  • .net ViewState in page lifecycle

    - by caltrop
    I have a page containing a control called PhoneInfo.ascx. PhoneInfo is dynamically created using LoadControl() and then the initControl() function is called passing in an initialization object to set some initial textbox values within PhoneInfo. The user then changes these values and hits a submit button on the page which is wired up to the "submit_click" event. This event invokes the GetPhone() function within PhoneInfo. The returned value has all of the new user entered values except that the phoneId value (stored in ViewState and NOT edited by the user) always comes back as null. I believe that the viewstate is responsible for keeping track of user entered data across a postback, so I can't understand how the user values are coming back but not the explicitly set ViewState["PhoneId"] value! If I set the ViewState["PhoneId"] value in PhoneInfo's page_load event, it retrieves it correctly after the postback, but this isn't an option because I can only initialize that value when the page is ready to provide it. I'm sure I am just messing up the page lifecycle somehow, any suggestion or questions would really help! I have included a much simplified version of the actual code below. Containing page's codebehind protected void Page_Load(object sender, EventArgs e) { Phone phone = controlToBind as Phone; PhoneInfo phoneInfo = (PhoneInfo)LoadControl("phoneInfo.ascx"); //Create phoneInfo control phoneInfo.InitControl(phone); //use controlToBind to initialize the new control Controls.Add(phoneInfo); } protected void submit_click(object sender, EventArgs e) { Phone phone = phoneInfo.GetPhone(); } PhoneInfo.ascx codebehind protected void Page_Load(object sender, EventArgs e) { } public void InitControl(Phone phone) { if (phone != null) { ViewState["PhoneId"] = phone.Id; txt_areaCode.Text = SafeConvert.ToString(phone.AreaCode); txt_number.Text = SafeConvert.ToString(phone.Number); ddl_type.SelectedValue = SafeConvert.ToString((int)phone.Type); } } public Phone GetPhone() { Phone phone = new Phone(); if ((int)ViewState["PhoneId"] >= 0) phone.Id = (int)ViewState["PhoneId"]; phone.AreaCode = SafeConvert.ToInt(txt_areaCode.Text); phone.Number = SafeConvert.ToInt(txt_number.Text); phone.Type = (PhoneType)Enum.ToObject(typeof(PhoneType), SafeConvert.ToInt(ddl_type.SelectedValue)); return phone; } }

  • QAS custom address layout

    - by DaveC
    I have been given a new format to add to the QAS ini file Qawserve.ini and want to use this format in the GetFormattedAddress() method call.

  • .NET ComboBox Autocomplete failing on slashes

    - by Clyde
    The .NET ComboBox autocomplete will not fully autocomplete with the display text contains a slash. It completes only up to the slash, leaving SelectedIndex == -1 and SelectedValue == null. This behavior stupidly persists no matter whether your autocompletesource is set to ListItems rather than FileSystem or URL. Is there any workaround for this that doesn't involve just throwing the ComboBox class away and writing a "MyComboBox" class?

  • How to bind a label inside a gridview to another table?

    - by Kolten
    I have a very standard Gridview, with Edit and Delete buttons auto-generated. It is bound to a tableadapter which is linked to my "RelationshipTypes" table. dbo.RelationshipTypes: ID, Name, OriginConfigTypeID, DestinationConfigTypeID I wish to use a label that will pull the name from the ConfigTypes table, using the "OriginConfigTypeID" and "DestinationTypeID" as the link. dbo.ConfigTypes: ID, Name My problem is, I can't automatically generate Edit and Delete buttons using an Inner Join in my dataset. Or can I? FOllowing is my code: <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" AutoGenerateDeleteButton="True" AutoGenerateEditButton="True" CssClass="TableList" DataKeyNames="ID" DataSourceID="dsRelationShipTypes1"> <Columns> <asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False" ReadOnly="True" SortExpression="ID" Visible=False/> <asp:TemplateField HeaderText="Origin" SortExpression="OriginCIType_ID"> <EditItemTemplate> &nbsp;<asp:DropDownList Enabled=true ID="DropDownList2" runat="server" DataSourceID="dsCIType1" DataTextField="Name" DataValueField="ID" SelectedValue='<%# Bind("OriginCIType_ID") %>'> </asp:DropDownList> </EditItemTemplate> <ItemTemplate> &nbsp; <asp:Label ID="Label2" runat="server" Text='<%# Bind("OriginCIType_ID") %>'></asp:Label> </ItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Name" SortExpression="Name"> <EditItemTemplate> <asp:TextBox ID="TextBox3" runat="server" Text='<%# Bind("Name") %>'></asp:TextBox> </EditItemTemplate> <ItemTemplate> <asp:Label ID="Label3" runat="server" Text='<%# Bind("Name") %>'></asp:Label> </ItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Destination" SortExpression="DestinationCIType_ID"> <EditItemTemplate> <asp:DropDownList ID="DropDownList3" runat="server" DataSourceID="dsCIType1" DataTextField="Name" DataValueField="ID" SelectedValue='<%# Bind("DestinationCIType_ID") %>'> </asp:DropDownList> </EditItemTemplate> <ItemTemplate> <asp:Label ID="Label1" runat="server" Text='<%# Bind("DestinationCIType_ID") %>'></asp:Label> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView> So I did try to create my own edit and delete buttons, but kept receiving the error "cannot find update method" or something similar.

  • ASP.NET Wizard control with Dynamic UserControls

    - by wjat777
    Hello everyone I'm trying to use the Wizard control as follows: 1 - In the first step (first screen) has a cheklistbox with several options 2 - For each option selected, will be created an extra step 3 - In some steps may be set up intermediate stages Me problem is that each step is a usercontrol. So if the first step I select option1 and option3, I should create two more steps with usercontrol1 and UserControl3 .... Someone already did something similar? I will try explain better the problem. I'll paste here, but I put a copy of the project in skydrive: http://cid-3d949f1661d00819.skydrive.live.com/self.aspx/C%5E3/WizardControl2.7z It is a very basic example of what I'm trying to do. The project has page.ASPX 1 and 3 usercontrol.ASCX (UC1, UC2 and UC3) Default.ASPX: <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebApplication2._Default" % Option1 Option2 Option3 Code Behind: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; namespace WebApplication2 { public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void Page_PreInit(object sender, EventArgs e) { LoadSteps(); } private void LoadSteps() { int count = Wizard1.WizardSteps.Count; for (int i = count - 1; i > 0; i--) { WizardStepBase step = Wizard1.WizardSteps[i]; if (step.StepType != WizardStepType.Start) Wizard1.WizardSteps.Remove(step); } string Activities=""; foreach (ListItem item in CheckBoxList1.Items) { if (item.Selected) { WizardStep step = new WizardStep {ID = "step_" + item.Value, Title = "step_" + item.Value}; UserControl uc=null; switch (item.Value) { case "1": uc=(UserControl)LoadControl("~/UC1.ascx"); break; case "2": uc=(UserControl)LoadControl("~/UC2.ascx"); break; case "3": uc=(UserControl)LoadControl("~/UC3.ascx"); break; } step.Controls.Add(uc); Wizard1.WizardSteps.Add(step); } } } protected void CheckBoxList1_SelectedIndexChanged(object sender, EventArgs e) { LoadSteps(); } } } Control UC1.ASCX to UC3.ASCX has the same code (as an example) usercontrol.ascx: <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="UC1.ascx.cs" Inherits="WebApplication2.UC1" % AutoPostBack="True" AutoPostBack="True" Code Behind: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; namespace WebApplication2 { public partial class UC1 : System.Web.UI.UserControl { protected void Page_Init(object sender, EventArgs e) { List list1 = new List { "Alice", "Bob", "Chris" }; List list2 = new List { "UN", "DEUX", "TROIS" }; DropDownList1.DataSource = list1; DropDownList2.DataSource = list2; DropDownList1.DataBind(); DropDownList2.DataBind(); } protected void Page_Load(object sender, EventArgs e) { if (IsPostBack) return; } protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e) { Label1.Text = DropDownList1.SelectedValue; } protected void DropDownList2_SelectedIndexChanged(object sender, EventArgs e) { Label2.Text = DropDownList2.SelectedValue; } } } You can see that the controls UserControls trigger events (they cause postbacks) The behavior of this project is a little different than I described in the first thread, but the problem is the same. After the second time "next" button, you will get an error. Thanks in advance William

  • How To Change The Screen Resolution in C#

    - by SAMIR BHOGAYTA
    All programmers are facing common problem is how to change screen Resolution dynamically. In .Net 2005 it's very easy to change the screen resolution. Here We will explain you how can we get the Screen resolution and how we will change the resolution at dynamically and while unloading the page it will come as it was before. In dot net we can access the values of user's screen resolution through the Resolution class. It also affects all running (and minimized) programs. Page_Load Function Screen Srn = Screen.PrimaryScreen; tempHeight = Srn.Bounds.Width; tempWidth = Srn.Bounds.Height; Page.ClientScript.RegisterStartupScript (this.GetType(), "Error", "alert('" + "Your Current Resolution is = " + tempHeight + " * " + tempWidth + "');"); //if you want Automatically Change res.at page load. //please uncomment this code. if (tempHeight == 600)//if the system is 800*600 Res.then change to { FixHeight = 768; FixWidth = 1024; Resolution.CResolution ChangeRes = new Resolution.CResolution(FixHeight, FixWidth); } Change Resoultion in C# switch (cboRes.SelectedValue.ToString()) { case "800*600": FixHeight = 800; FixWidth = 600; Resolution.CResolution ChangeRes600 = new Resolution.CResolution(FixHeight, FixWidth); break; case "1024*768": FixHeight = 1024; FixWidth = 768; Resolution.CResolution ChangeRes768 = new Resolution.CResolution(FixHeight, FixWidth); break; case "1280*1024":How To Change The Screen Resolution in C# FixHeight = 1280; FixWidth = 1024; Resolution.CResolution ChangeRes1024 = new Resolution.CResolution(FixHeight, FixWidth); break; }

  • Problems re-populating select options in Rails when form returned with errors

    - by Rick
    I have a form with 2 select options in it -- frequency and duration. When there are errors with the form, and it is returned to the browser, the select options are not re-populated with the selections the user made even though the returned values for those fields match the values of options in the selects. Also, when the form is returned, these fields are not marked as having errors even though their values are blank. Here's the frequency and duration fields in Rails <%= frequency_select c, :frequency %> <%= duration_select c, :duration %> The method for frequency_select is def frequency_select(f, method) options = [["day", 1.day], ["other day", 2.days], ["week", 1.week]] f.select method, options, :include_blank => true end And the method for duration_select is def duration_select(f, method, unit="day" ) values, units = *case unit when "day" : [[[5, 5], [15, 15], [30, 29]], "days"] when "other day" : [[[15, 15], [30, 29], [45,45]], "days"] when "week" : [[[4, 29], [6, 43], [8, 57]], "weeks"] end f.select method, values.map {|(label, i)| ["#{label} #{units}", i.days]}, :include_blank => true end If you enter a value into one or both of these fields and submit the form without completing part of it (any part of it), the form is returned to the user (as would be expected), but the duration and frequency fields are not re-populated with the user's selection. If I add this bit of code to the form <p><%= @challenge.attributes.inspect %></p> I see that this for duration and frequency when the form is returned to the browser: "duration"=>3888000, "frequency"=>172800 These values match values on the options in the select fields. Is there anything special in Rails that needs to be done so that the select fields are re-populated with the user's selections? Any thoughts on what the problem could be or what I should try next? Help is greatly appreciated! -Rick PS If you look at some of the other questions, you'll notice I've asked about this in the past. At one point, I thought the form was returning values for frequency and duration in days rather than seconds, but that's not the case. PPS Here's one other bit of information that might matter, but my tests indicate that it probably does not. (Though, I'm a bit of a newbie to this, so don't take my word for it.) These two fields are chained together using the cascade jquery plugin. The javascript is included on the page (not in a separate file) and some of the js is being created by Rails. First, here are the scripts as they appear in the browser. The first is the script to generate the options for the duration select and the second is the script required by the Cascade plugin to trigger the field chaining. <script type="text/javascript"> var list1 = [ {'When':'86400','Value':' ','Text':' '}, {'When':'172800','Value':' ','Text':' '}, {'When':'604800','Value':' ','Text':' '}, {'When':'86400','Value':'432000','Text':'5 days'}, {'When':'86400','Value':'1296000','Text':'15 days'}, {'When':'86400','Value':'2505600','Text':'30 days'}, {'When':'172800','Value':'1296000','Text':'15 days'}, {'When':'172800','Value':'2505600','Text':'30 days'}, {'When':'172800','Value':'3888000','Text':'45 days'}, {'When':'604800','Value':'2505600','Text':'4 weeks'}, {'When':'604800','Value':'3715200','Text':'6 weeks'}, {'When':'604800','Value':'4924800','Text':'8 weeks'} ]; function commonTemplate(item) { return "<option value='" + item.Value + "'>" + item.Text + "</option>"; }; function commonMatch(selectedValue) { return this.When == selectedValue; }; </script> <script type="text/javascript"> jQuery(document).ready(function(){ jQuery("#challenge_duration, #user_challenge_duration").cascade("#challenge_frequency, #user_challenge_frequency",{ list: list1, template: commonTemplate, match: commonMatch }) }); </script> And here's a bit of the the first script as it is in the erb file -- you see that some of the script is being generated by Rails <%= [ [1.day, [[5, 5], [15,15], [30, 29]], "days"], [2.days, [[15, 15], [30, 29], [45, 45]], "days"], [1.week, [[4, 29], [6, 43], [8, 57]], "weeks"]].map do |(frequency, durations, unit)| durations.map do |(label, value)| "{'When':'#{frequency}','Value':'#{value.days}','Text':'#{label} #{unit}'}" end end.join(",\n") -%> Now, the reason I don't think that it matters whether the duration is being generated with JS is the problem still exists if I remove all the JS the problem also affects the frequency field, whose options are not being generated by the JS

  • Programatically add UserControl with events

    - by schaermu
    Hi everybody I need to add multiple user controls to a panel for further editing of the contained data. My user control contains some panels, dropdown lists and input elements, which are populated in the user control's Page_Load event. protected void Page_Load(object sender, EventArgs e) { // populate comparer ddl from enum string[] enumNames = Enum.GetNames(typeof (SearchComparision)); var al = new ArrayList(); for (int i = 0; i < enumNames.Length; i++) al.Add(new {Value = i, Name = enumNames[i]}); scOperatorSelection.DataValueField = "Value"; scOperatorSelection.DataTextField = "Name"; ... The data to be displayed is added to the user control as a Field, defined above Page_Load. The signature of the events is the following: public delegate void ControlStateChanged(object sender, SearchCriteriaEventArgs eventArgs); public event ControlStateChanged ItemUpdated; public event ControlStateChanged ItemRemoved; public event ControlStateChanged ItemAdded; The update button on the user control triggers the following method: protected void UpdateCriteria(object sender, EventArgs e) { var searchCritCtl = (SearchCriteria) sender; var scEArgs = new SearchCriteriaEventArgs { TargetCriteria = searchCritCtl.CurrentCriteria.CriteriaId, SearchComparision = ParseCurrentComparer(searchCritCtl.scOperatorSelection.SelectedValue), SearchField = searchCritCtl.scFieldSelection.SelectedValue, SearchValue = searchCritCtl.scFilterValue.Text, ClickTarget = SearchCriteriaClickTarget.Update }; if (ItemUpdated != null) ItemUpdated(this, scEArgs); } The rendering page fetches the data objects from a storage backend and displays it in it's Page_Load event. This is the point where it starts getting tricky: i connect to the custom events! int idIt = 0; foreach (var item in _currentSearch.Items) { SearchCriteria sc = (SearchCriteria)LoadControl("~/content/controls/SearchCriteria.ascx"); sc.ID = "scDispCtl_" + idIt; sc.ControlMode = SearchCriteriaMode.Display; sc.CurrentCriteria = item; sc.ItemUpdated += CriteriaUpdated; sc.ItemRemoved += CriteriaRemoved; pnlDisplayCrit.Controls.Add(sc); idIt++; } When first rendering the page, everything is displayed fine, i get all my data. When i trigger an update event, the user control event is fired correctly, but all fields and controls of the user control are NULL. After a bit of research, i had to come to the conclusion that the event is fired before the controls are initialized... Is there any way to prevent such behavior / to override the page lifecycle somehow? I cannot initialize the user controls in the page's Init-event, because i have to access the Session-Store (not initialized in Page_Init). Any advice is welcome... EDIT: Since we hold all criteria informations in the storage backend (including the count of criteria) and that store uses the userid from the session, we cannot use Page_Init... just for clarification EDIT #2: I managed to get past some of the problems. Since i'm now using simple types, im able to bind all the data declaratively (using a repeater with a simple ItemTemplate). It is bound to the control, they are rendered in correct fashion. On Postback, all the data is rebound to the user control, data is available in the OnDataBinding and OnLoad events, everything looks fine. But as soon it enters the real event (bound to the button control of the user control), all field values are lost somehow... Does anybody know, how the page lifecycle continues to process the request after Databinding/Loading ? I'm going crazy about this issue...

  • How do I check if selected value of the DropDown List is not selected in C#?

    - by Sahat
    This code will display the selected value from the drop down list. E.g. if I sellect Item 1 I will get the following output: You have selected Item 1. Label1.Text = "You have selected " + DropDownList1.SelectedValue + "<br />"; But if I don't select anything and click on Submit button, I will get: You have selected What would I need to make it display "You have not selected anything. Please select at least 1 item."

  • MVC Dropdown List isn't binding to the model.

    - by Rod McLeay
    Hi, I am trying set up a simple dropdown list but I dont seem to be able to get it to bind to the Model. I am using Asp.Net MVC and nhibernate. My dropdown list is declared like so: <%= Html.DropDownListFor(model => model.Project, (IEnumerable<SelectListItem>)ViewData["Projects"], " -- Select -- ", new { name = "Project" })%> I set up the select list like so: ViewData["Projects"] = new SelectList(projectRepository.GetAll(), "EntityGUID", "Name", editEntity.Project); This seems to bind the select list to the Dropdown fine, but the SelectedValue is not set. it shows up as the default --- Select --- Also when I save this data, the dropdown does not bind to the model, I have to manually set the object like so to save it: entity.Project = projectRepository.GetById(new Guid(Request["Project"].ToString())); I believe I have take the correct messures to have this item bind directly to my model. Is there something I am missing here? Many thanks for your time, Rod

  • Databind gridview with LINQ

    - by Anders Svensson
    I have two database tables, one for Users of a web site, containing the fields "UserID", "Name" and the foreign key "PageID". And the other with the fields "PageID" (here the primary key), and "Url". I want to be able to show the data in a gridview with data from both tables, and I'd like to do it with databinding in the aspx page. I'm not sure how to do this, though, and I can't find any good examples of this particular situation. Here's what I have so far: <%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="LinqBinding._Default" %> <asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent"> </asp:Content> <asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent"> <h2> Testing LINQ </h2> <asp:GridView ID="GridView1" runat="server" DataSourceID="LinqDataSourceUsers" AutoGenerateColumns="false"> <Columns> <asp:CommandField ShowSelectButton="True" /> <asp:BoundField DataField="UserID" HeaderText="UserID" /> <asp:BoundField DataField="Name" HeaderText="Name" /> <asp:BoundField DataField="PageID" HeaderText="PageID" /> <asp:TemplateField HeaderText="Pages"> <ItemTemplate <asp:DropDownList ID="DropDownList1" DataSourceID="LinqDataSourcePages" SelectedValue='<%#Bind("PageID") %>' DataTextField="Url" DataValueField="PageID" runat="server"> </asp:DropDownList> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView> <asp:LinqDataSource ID="LinqDataSourcePages" runat="server" ContextTypeName="LinqBinding.UserDataContext" EntityTypeName="" TableName="Pages"> </asp:LinqDataSource> <asp:LinqDataSource ID="LinqDataSourceUsers" runat="server" ContextTypeName="LinqBinding.UserDataContext" EntityTypeName="" TableName="Users"> </asp:LinqDataSource> </asp:Content> But this only works in so far as it gets the user table into the gridview (that's not a problem), and I get the page data into the dropdown, but here's the problem: I of course get ALL the page data in there, not just the pages for each user on each row. So how do I put some sort of "where" constraint on dropdown for each row to only show the pages for the user in that row? (Also, to be honest I'm not sure I'm getting the foreign key relationship right, because I'm not too used to working with relationships). EDIT: I think I have set up the relationship incorrectly. I keep getting the message that "Pages" doesn't exist as a property on the User object. And I guess it can't since the relationship right now is one way. So I tried to create a many-to-many relationship. Again, my database knowledge is a bit limited, but I added a so called "junction table" with the fields UserID and PageID, same as the other tables' primary keys. I wasn't able to make both of these primary keys in the junction table though (which it looked like some people had in examples I've seen...but since it wasn't possible I guessed they shouldn't be). Anyway, I created a relationship from each table and created new LINQ classes from that. But then what do I do? I set the junction table as the Linq data source, since I guessed I had to do this to access both tables, but that doesn't work. Then it complains there is no Name property on that object. So how do I access the related tables? Here's what I have now with the many-to-many relationship: <%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="ManyToMany._Default" %> <asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent"> </asp:Content> <asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent"> <h2> Many to many LINQ </h2> <asp:GridView ID="GridView1" runat="server" DataSourceID="LinqDataSource1" AutoGenerateColumns="false"> <Columns> <asp:CommandField ShowSelectButton="True" /> <asp:BoundField DataField="UserID" HeaderText="UserID" /> <asp:BoundField DataField="Name" HeaderText="Name" /> <asp:BoundField DataField="PageID" HeaderText="PageID" /> <asp:TemplateField HeaderText="Pages"> <ItemTemplate> <asp:DropDownList ID="DropDownList1" DataSource='<%#Eval("Pages") %>' SelectedValue='<%#Bind("PageID") %>' DataTextField="Url" DataValueField="PageID" runat="server"> </asp:DropDownList> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView> <asp:LinqDataSource ID="LinqDataSource1" runat="server" ContextTypeName="ManyToMany.UserPageDataContext" EntityTypeName="" TableName="UserPages"> </asp:LinqDataSource> </asp:Content>
