    How can I add rows in a table from server-side? if (!Page.IsPostBack) { Session["table"] = TableId; }else TableId = (Table)Session["table"]; } protected void btnAddinRow_Click(object sender, EventArgs e) { num_row = (TableId.Rows).Count; TableRow r = new TableRow(); TableCell c1 = new TableCell(); TableCell c2 = new TableCell(); TextBox t = new TextBox(); t.ID = "textID" + num_row; t.EnableViewState = true; r.ID = "newRow" + num_row; c1.ID = "newC1" + num_row; c2.ID = "newC2" + num_row; c1.Text = "New Cell - " + num_row; c2.Controls.Add(t); r.Cells.Add(c1); r.Cells.Add(c2); TableId.Rows.Add(r); Session["table"] = TableId; } in debug I found out the number in the "TableID", but the rows are not drawn. Have you got an idea about this issue? Thanks

  • Dynamically created textboxes and changes plus jQuery in ASP.NET?

    - by gazeebo
    Hi all, I was wondering how to read off a value from a textbox that resides in a partialview and output the value into a textbox within the initial window. Here's my code... <script type="text/javascript"> $(document).ready(function (e) { // Calculate the sum when the document has been loaded. var total = 0; $("#fieldValues :input.fieldKronor").each(function (e) { total += Number($(this).val()); }); // Set the value to the correspondent textbox $("#fieldSummation").text(total); // Re-calculate on change $("#fieldValues :input.fieldKronor").change(function (e) { var total = 0; $("#fieldValues :input.fieldKronor").each(function (e) { total += Number($(this).val()); }); $("#fieldSummation").text(total); }); }); </script> Here's the table where in info is... <table id="fieldValues" style="width: 60%; margin-bottom: 2em"> <thead> <tr> <th>Rubrik, t.ex. teknik*</th> <th>Kronor (ange endast siffror)*</th> </tr> </thead> <asp:Panel ID="pnlStaffRows" runat="server"></asp:Panel> <tfoot> <tr> <th></th> <th>Total kostnad</th> </tr> <tr> <td></td> <td><input type="text" value="" class="fieldSummation" style="width:120px" /></td> </tr> </tfoot> </table> And here's the partialview... <tr> <td class="greyboxchildsocialsecuritynumberheading4" style="padding-bottom:1em"> <asp:TextBox ID="txtRubrikBox" ToolTip="Rubrik" runat="server" Width="120"></asp:TextBox> </td> <td class="greyboxchildnameheading3" style="padding-bottom:1em"> <asp:TextBox ID="txtKronorBox" class="fieldKronor" ToolTip="Kronor" runat="server" Width="120"></asp:TextBox> </td> </tr>

  • How to retrieve ID of button clicked within usercontrol on Asp.net page?

    - by Shawn Gilligan
    I have a page that I am working on that I'm linking multiple user controls to. The user control contains 3 buttons, an attach, clear and view button. When a user clicks on any control on the page, the resulting information is "dumped" into the last visible control on the page. <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="Default" MasterPageFile="DefaultPage.master" %> <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %> <%@ Register tagName="FileHandler" src="FileHandling.ascx" tagPrefix="ucFile" %> <asp:Content ID="Content1" ContentPlaceHolderID="Main" Runat="Server"> <asp:UpdatePanel ID="upPanel" UpdateMode="Conditional" runat="server"> <ContentTemplate> <table> <tr> <td> <ucFile:FileHandler ID="fFile1" runat="server" /> </td> <td> <ucFile:FileHandler ID="fFile2" runat="server" /> </td> </tr> </table> </ContentTemplate> </asp:UpdatePanel> </asp:Content> All file handling and processing is handled within the control, with an event when the upload to the file server is complete via a file name that was generated. When either button is clicked, the file name is always stored internal to the control in the last control's text box. Control code: <table style="width: 50%;"> <tr style="white-space: nowrap;"> <td style="width: 1%;"> <asp:Label runat="server" ID="lblFile" /> </td> <td style="width: 20%;"> <asp:TextBox ID="txtFile" CssClass="backColor" runat="server" OnTextChanged="FileInformationChanged" /> </td> <td style="width: 1%"> <%--<asp:Button runat="server" ID="btnUpload" CssClass="btn" Text="Attach" OnClick="UploadFile"/>--%> <input type="button" id="btnUpload" class="btn" tabindex="30" value="Attach" onclick="SetupUpload();" /> </td> <td style="width: 1%"> <%--<asp:Button runat="server" ID="btnClear" Text="Clear" CssClass="btn" OnClick="ClearTextValue"/>--%> <input type="button" id="btnClearFile" class="btn" value="Clear" onclick="document.getElementById('<%=txtFile.ClientID%>').value = '';document.getElementById('<%=hfFile.ClientID%>').value = '';" /> </td> <td style="width: 1%"> <a href="#here" onclick="ViewLink(document.getElementById('<%=hfFile.ClientID%>').value, '')">View</a> </td> <td style="width: 1%"> <asp:HiddenField ID="hfFile" runat="server" /> </td> </tr> </table> <script type="text/javascript"> var ItemPath = ""; function SetupUpload(File) { ItemPath = File; VersionAttach('<%=UploadPath%>', 'true'); } function UploadComplete(File) { document.getElementById('<%=txtFile.ClientID%>').value = File.substring(File.lastIndexOf("/") + 1); document.getElementById('<%=hfFile.ClientID%>').value = File; alert('<%=txtFile.Text %>'); alert('<%=ClientID %>') } function ViewLink(File, Alert) { if (File != "") { if (File.indexOf("../data/") != -1) { window.open(File, '_blank'); } else { window.open('../data/<%=UploadPath%>/' + File, '_blank'); } } else if (Alert == "") { alert('No file has been uploaded for this field.'); } } </script>

  • How to find which existing .NET solutions contain a project?

    - by Daniel Daranas
    I am exploring a structure of folders with C# projects such as the following: Projects ProjectA ProjectB ProjectC ProjectD Scattered around in the same folders as the .csproj files, there are several solution (.sln) files. Is there a fast way to find all the solutions that contain ProjectD.vsproj? I can open them one by one and see what they contain, but I would like a feature such as "find all the solutions containing this project".

  • Shrink a cell (in an absolutely-positioned ASP.NET table) to fit its contents?

    - by Giffyguy
    My webpage currently looks like this: <asp:Table runat="server" style="position: absolute; left: 0%; top: 82%; right: 0%; bottom: 0%; width: 100%; height: 18%" CellPadding="0" CellSpacing="0" GridLines="Both"> <asp:TableRow> <asp:TableCell> Content1 </asp:TableCell> <asp:TableCell Width="2.5%"> </asp:TableCell> <asp:TableCell > Content2 </asp:TableCell> </asp:TableRow> </asp:Table> But I need it to look like this: "Content1" is of unknown size, and the table will have to adjust to fit it in, but without taking any unnecessary space away from "Content2." I can't use "display: table" because it isn't supported in IE7 and such, so I'm pretty much stuck using a regular table element unless there is something better out there that is supported in older browsers. Does anyone know how this can be accomplished?

  • How do I obtain an HtmlHelper<TModel> instance for a model in ASP.NET MVC?

    - by DanM
    Let's say I have an Index view. The model I pass in is actually a collection of models, so the Html property is of type HtmlHelper<List<MyModel>>. If I want to call extension methods (e.g., Display() or DisplayFor() on the individual items in the list, however, I think I need to obtain an HtmlHelper<MyModel>. But how? I tried using the HtmlHelper<TModel> constructor, which looks like this: HtmlHelper<TModel>(ViewContext, IViewDataContainer) But I'm not having any luck with that. I don't know how to obtain the IViewDataContainer for the item, and the documentation on these things is very sparse. A lot of magic apparently happens when I do... return View(List<MyModel>); ...in my controller. How do I recreate that magic on individual items in a list/collection?

  • Difference between `<%#` and `<%=` and an asp.net ascx file?

    - by jax
    I understand that <%= is for returning a String I seem to usually use <%# in my .ascx files. For example the following works OnClientClick=<%# String.Format("return confirm('Are you sure you wish to delete barcode ({0})?');", Eval("BARCODE") ) %> The following does not work OnClientClick=<%# String.Format("return confirm('Are you sure you wish to delete barcode ({0})?');", Eval("BARCODE") ) %>

  • Post data with jQuery to ASP.net, am I doing this secure enough?

    - by Wim Haanstra
    For a website I am building, I am using jQuery to post data to Generic Handlers I created for this purpose. Because you need to be logged in, to do most post actions (like 'rate a picture'), I am currently using the following technique: User visits page Page determines if user is logged in On Page_Load the page fills a hidden field with an encrypted string, which contains several needed variables, like User ID, Picture ID (of the picture they are currently viewing), the DateTime when the page was rendered. When the user clicks a "I like this picture"-button, I do a $.ajax post to my Generic Handler, with the encrypted string and the value whether or not they liked the picture. The Generic Handler decrypts the supplied encrypted string and takes a look at the DateTime to determine if it was not too long ago When everything works out, the vote is submitted to the database. In my understanding this is a pretty secure way to handle a situation like this. But maybe I am missing a very important point here. Any advice would be very welcome.

  • How to display popup from code-behind in ASP.net ?

    - by user359706
    hello I wonder how it would be possible to launch a series of popups, containing a form, from code-behind. I possess a list of objects 'Products' and I wish I could change one property (quantity) of each "product". Here's how I build my list (normally I use a database). Private List<Product> listProduct; listProduits = new List<Product>(); Product objProduit_1 = new Produit; objProduct_1.ref = "001"; objProduct_1.article = "G900"; objProduct_1.quantity = 30; listProducts.Add(objProduct_1); ProductobjProduit_2 = new Product; objProduct_2.ref = "002"; objProduct_2.article = "G900"; objProduct_2.quantity = 35; listProduits.Add(objProduct_2); And I would like displayed popup one after one. Thank you in advance for your help

  • asp.net datasource in memory which component suites this better?

    - by Mike
    I need to create a page that has a listbox with databound items. Upon clicking an entry in the listbox, the page will postback and insert an entry into a listview. The listview should have the item's name, and a textbox allowing the user to edit the value for each. I don't want the listview to be in "edit" mode. I just want the user to be able to update the value. Is this possible?

  • In .NET Xml Serialization, is it possible to serialize a class with an enum property with different

    - by Lasse V. Karlsen
    I have a class, containing a list property, where the list contains objects that has an enum property. When I serialize this, it looks like this: <?xml version="1.0" encoding="ibm850"?> <test> <events> <test-event type="changing" /> <test-event type="changed" /> </events> </test> Is it possible, through attributes, or similar, to get the Xml to look like this? <?xml version="1.0" encoding="ibm850"?> <test> <events> <changing /> <changed /> </events> </test> Basically, use the property value of the enum as a way to determine the tag-name? Is using a class hierarchy (ie. creating subclasses instead of using the property value) the only way? Edit: After testing, it seems even a class-hierarchy won't actually work. If there is a way to structure the classes to get the output I want, even with sub-classes, that is also an acceptable answer. Here's a sample program that will output the above Xml (remember to hit Ctrl+F5 to run in Visual Studio, otherwise the program window will close immediately): using System; using System.Collections.Generic; using System.Xml.Serialization; namespace ConsoleApplication18 { public enum TestEventTypes { [XmlEnum("changing")] Changing, [XmlEnum("changed")] Changed } [XmlType("test-event")] public class TestEvent { [XmlAttribute("type")] public TestEventTypes Type { get; set; } } [XmlType("test")] public class Test { private List<TestEvent> _Events = new List<TestEvent>(); [XmlArray("events")] public List<TestEvent> Events { get { return _Events; } } } class Program { static void Main(string[] args) { Test test = new Test(); test.Events.Add(new TestEvent { Type = TestEventTypes.Changing }); test.Events.Add(new TestEvent { Type = TestEventTypes.Changed }); XmlSerializer serializer = new XmlSerializer(typeof(Test)); XmlSerializerNamespaces ns = new XmlSerializerNamespaces(); ns.Add("", ""); serializer.Serialize(Console.Out, test, ns); } } }

  • How do I pass a javascript parameter to an asp.net MVCmodel from within a View?

    - by Josh
    Hi everyone! I am having an issue trying to access a list property on a model from within a javascript. My basic situation is this: I have an ArticleController and an ArticleViewModel. An Article has a number of properties, one of which is Text, which is just a string that contains the contents of the article. The ArticleViewModel contains a Pages property, which is just a List of Strings. When the ArticleViewModel constructor is called, I populate the Pages list by dividing up the article text based on some delimeters. I have a View which inherits the ArticleViewModel type. What I want to do is only display one page at a time, and then when the user clicks a page number (from a list at the bottom of the article), I want to use javascript to load that page into the #dynamicContent div. The problem: I can't seem to pass a parameter to the Model.Pages property from within javascript... Is this possible? I get an error stating, "Expression Expected" when I try what I have below. I don't want to have to worry about AJAX calls or anything like that since I already have the entire article... I just need a way to access each individual page from within the javascript function. Alternatively, if there is a better solution for "paginating" an article so that I can load each articlePage without having to refresh the entire html page, I would certainly be open to that as well. Any help would be much appreciated!! Thanks for your time! ArticleView Code: Script at the top of the view: function loadPage(pageNumber) { try { alert(pageNumber); $('#dynamicContent').html('<%=Model.Pages(' + pageNumber + ') %>'); } catch (e) { alert('in here'); alert(e.description); } } HTML for view: [...] <div id="articleBody"> <div id="dynamicContent"> <%=Model.Pages(0)%> </div> </div> [...] Page Links at bottom of page: [...] <div> <ul style="display:block"> <li style="display:inline"> <a href="#articleTitle" onclick="loadPage(0)"> 1 </a> </li> <li style="display:inline"> <a href="#articleTitle" onclick="loadPage(1)"> 2 </a> </li> </ul> </div>
