  • What is a best free way to make form resizeable in Delphi 7?

    - by Tofig Hasanov
    I need my form in Delphi to be resizeable, and all components and controls should stretch proportionally, along with font sizes etc. Right now in order to resize components I write a code inside "OnResize" event, and manually calculate all components' sizes and fonts. I would like to have more simple solution, which I can apply to different applications without rewriting this code for each form. I found some components on the web, but they are shareware. Can you suggest something?

  • Changing the style of a Combo-Box in WPF (in Blend preferably)

    - by George Sealy
    I'm having some issues trying to change the look / style of a combo box in Expression Blend / WPF. While there are tutorials out there describing setting styles for buttons, there seem to be a few wrinkles with ComboBox controls. Can anyone offer any advice, or point me towards good tutorials that cover re-styling something more complex than a button?

  • Silverlight control locked in runtime

    - by user194979
    I have a online survey running in Silverlight. Out of more than 1000 onetime users, there are three users than cannot open a combobox on the first page. The control seems disabled and don't react on mouseclick. Since it is one-time user, they don't wan't to help me with debugging and I cannot reproduce the problem myself. Any ideas why 1000 users have no problem, and 3 are experiencing all controls like they were disabled?

  • How to loop through the ChartColorPalette properties and add to list?

    - by John M
    I am using the Microsoft Chart Controls for .NET 3.5 (C#) and have a chart in a winform. My hope is to allow the user to change the color palette based on their preference. How do I iterate through the color properties of the ChartColorPalette and add them to a combobox list? I know it should be something like: for each(something in ChartColorPalette) { combobox.items.add(something.ToString); }

  • User control events not getting to their handlers

    - by PhrkOnLsh
    I am trying to create a user control to wrap around the Membership API (A set of custom Gridviews to display the data better) and, while the code and the controls worked fine in the page, when I moved them to an .ascx, the events stopped firing to it. <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="CustomMembership.ascx.cs" Inherits="CCGlink.CustomMembership" %> <asp:Panel ID="mainPnl" runat="server"> <asp:Label id="lblError" ForeColor="Red" Font-Bold="true" runat="server" /> <asp:GridView id="grdUsers" HeaderStyle-cssclass="<%# _headercss %>" RowStyle-cssclass="<%# _rowcss %>" AlternatingRowStyle-cssclass="<%# _alternatingcss %>" OnRowUpdating="grdUsers_RowUpdating" OnRowDeleting="grdUsers_RowDeleting" OnRowCancelingEdit="grdUsers_cancelEdit" autogeneratecolumns="false" allowsorting="true" AllowPaging="true" EmptyDataText="No users..." pagesize="<%# PageSizeForBoth %>" runat="server"> <!-- ...columns... --> </asp:GridView> <asp:Button id="btnAllDetails" onclick="btnAllDetails_clicked" text="Full Info" runat="server" /> <asp:GridView DataKeyNames="UserName" HeaderStyle-cssclass="<%# _headercss %>" RowStyle-cssclass="<%# _rowcss %>" AlternatingRowStyle-cssclass="<%# _alternatingcss %>" id="grdAllDetails" visible="false" allowsorting="true" EmptyDataText="No users in DB." pagesize="<%# PageSizeForBoth %>" runat="server" /> <asp:Button id="btnDoneAllDetails" onclick="btnAllDetails_clicked" text="Done." Visible="false" runat="server" /> </asp:Panel> However, none of the events in the first two controls (the gridview grdUsers and the button btnAllDetails) simply do NOT occur, I have verified this in the debugger. If they occured just fine in the aspx page, why do they die on moving to the ascx? My code in the aspx now is: <div class="admin-right"> <asp:ScriptManager ID="sm1" runat="server" /> <h1>User Management</h1> <div class="admin-right-users"> <asp:UpdatePanel ID="up1" runat="server"> <ContentTemplate> <cm1:CustomMembership id="showUsers" PageSizeForBoth="9" AlternatingRowStylecssclass="alternating" RowStylecssclass="row" DataSource="srcUsers" HeaderStylecssclass="header" runat="server" /> </ContentTemplate> </asp:UpdatePanel> </div> Thanks.

  • User control disapear when added to a Panel

    - by dutt
    I've got a user control class that works fine, drawing, events firing and the works. When i programmaticly add it to a class that extends from Panel it disapears. I've checked around and the line that makes it disapear is the line where i go panel.Controls.Add(myuserControl). Without that line the control works just fine, does anybody know why it won't show after the add? I'm currently doing the painting of the user control by overriding OnPaint, but the panel is using the default painting.

  • Asp controls Id generation inside repeater

    - by toraan
    I define some controls inside repeater itemtemplate, the problem is with the Id that are generated automatically. This is my page: <asp:Repeater ID="rptThreads" runat="server" onitemcreated="rptThreads_ItemCreated"> <HeaderTemplate> <table cellpadding="0px" cellspacing="0"> </HeaderTemplate> <ItemTemplate> <tr style="height:50px"> <td> <asp:PlaceHolder ID="plcItemTitle" runat="server"> <asp:Panel id="titleContainer" runat="server" style="position:absolute;"> <asp:HyperLink ID="lnkTitle" runat="server" style="float:left;padding-right:10px;" Text='<%# Container.DataItem%>'/> <asp:Panel id="pnlEditButtons" runat="server" Visible="false" style="vertical-align:middle;z-index:100;display:none;float:left;" > <asp:ImageButton ID="imgbtn1" runat="server" ImageUrl="~/Images/misc/edit.png" /> <asp:ImageButton ID="imgbtn2" runat="server" ImageUrl="~/Images/misc/Rename.png" /> </asp:Panel> </asp:Panel> </asp:PlaceHolder> </td> </tr> </ItemTemplate> <FooterTemplate> </table> </FooterTemplate> </asp:Repeater> Now I will try to describe the problem: code-behind: protected void Page_Load(object sender, EventArgs e) { int [] array = {1,2,3,4,5}; rptThreads.DataSource = array; rptThreads.DataBind(); } protected void rptThreads_ItemCreated(object sender, RepeaterItemEventArgs e) { if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) { Panel editButtonsPanel = e.Item.FindControl("pnlEditButtons") as Panel; editButtonsPanel.Visible = true; Panel containerPanel = e.Item.FindControl("titleContainer") as Panel; //Point of Interest!!!! containerPanel.Attributes.Add("onmouseover", "ShowEditButtons('" + editButtonsPanel.ClientID + "');"); } } If I run the page as is, the generated html will be the following (I show only the first 2 items): <table cellpadding="0px" cellspacing="0"> <tr style="height:50px"> <td> <div id="titleContainer" onmouseover="ShowEditButtons('pnlEditButtons');" style="position:absolute;"> <a id="lnkTitle" style="float:left;padding-right:10px;">1</a> <div id="pnlEditButtons" style="vertical-align:middle;z-index:100;display:none;float:left;"> <input type="image" name="imgbtn1" id="imgbtn1" src="Images/misc/edit.png" style="border-width:0px;" /> <input type="image" name="imgbtn2" id="imgbtn2" src="Images/misc/Rename.png" style="border-width:0px;" /> </div> </div> </td> </tr> <tr style="height:50px"> <td> <div id="titleContainer" onmouseover="ShowEditButtons('pnlEditButtons');" style="position:absolute;"> <a id="lnkTitle" style="float:left;padding-right:10px;">2</a> <div id="pnlEditButtons" style="vertical-align:middle;z-index:100;display:none;float:left;"> <input type="image" name="imgbtn1" id="imgbtn1" src="Images/misc/edit.png" style="border-width:0px;" /> <input type="image" name="imgbtn2" id="imgbtn2" src="Images/misc/Rename.png" style="border-width:0px;" /> </div> </div> </td> </tr> As you can see all divs get the SAME ID, THIS I DONT WANT!!! But If I omit this line form the ItemCreated event: containerPanel.Attributes.Add("onmouseover", "ShowEditButtons('" + editButtonsPanel.ClientID + "');"); The generated HTML will be the following: <table cellpadding="0px" cellspacing="0"> <tr style="height:50px"> <td> <div id="rptThreads_ctl01_titleContainer" style="position:absolute;"> <a id="rptThreads_ctl01_lnkTitle" style="float:left;padding-right:10px;">1</a> <div id="rptThreads_ctl01_pnlEditButtons" style="vertical-align:middle;z-index:100;display:none;float:left;"> <input type="image" name="rptThreads$ctl01$imgbtn1" id="rptThreads_ctl01_imgbtn1" src="Images/misc/edit.png" style="border-width:0px;" /> <input type="image" name="rptThreads$ctl01$imgbtn2" id="rptThreads_ctl01_imgbtn2" src="Images/misc/Rename.png" style="border-width:0px;" /> </div> </div> </td> </tr> <tr style="height:50px"> <td> <div id="rptThreads_ctl02_titleContainer" style="position:absolute;"> <a id="rptThreads_ctl02_lnkTitle" style="float:left;padding-right:10px;">2</a> <div id="rptThreads_ctl02_pnlEditButtons" style="vertical-align:middle;z-index:100;display:none;float:left;"> <input type="image" name="rptThreads$ctl02$imgbtn1" id="rptThreads_ctl02_imgbtn1" src="Images/misc/edit.png" style="border-width:0px;" /> <input type="image" name="rptThreads$ctl02$imgbtn2" id="rptThreads_ctl02_imgbtn2" src="Images/misc/Rename.png" style="border-width:0px;" /> </div> </div> </td> </tr> All divs get unique IDs, and this I do want My questions are: 1)why it happens? why this line of code messup the ids? 2)how can have the unique ID's and assign javascript in codebehind? I can add this on aspx (it will wotk and I will get unique ids): onmouseover='<%# "javascript:ShowEditButtons(\""+ Container.FindControl("pnlEditButtons").ClientID+ "\");" %>' But I must do it in codebehind because I need to set the javascript only if server validate some things.

  • Taking a look at the Mindscape Phone Elements for WP7.

    - by mbcrump
    I recently heard that Mindscape HQ had released the Windows Phone 7 Controls and had to take a look at them. 100 FREE LICENSE GIVEAWAY! Before we get to the screenshots, you will be pleased to learn that my usergroup called “Allaboutxaml” has partnered with Mindscape HQ and are giving away 100 license. You can check out the site here to get your free controls. But please hurry as after the 100 are gone then I will not have any more to give away! A few links to read first: The official blog post from Mindscape HQ detailing the release. They also have the links to download the trial and get started. The phone elements official forum! So, let’s get started. After you download the controls go ahead and double click the .exe to get started installing them. After everything is installed then you will have the following program group. I’d recommend clicking on the Phone Elements Directory to get started: Let’s go over each element: Bin – Just the .DLL that’s required to use Mindscape HQ WP7 Controls in your project. Documentation – a .CHM File that will show you how to get your project up and running quickly. Resources – Just a few image files Samples – This is a full WP7 project that details every controls. The thing that I was most interested in was how the controls look and is it easy to use. I always believed if your paying for controls then you should hold my hand through using them. You will be pleased to know that Mindscape made it very easy to use. First, the WP7 project in the “Samples” folder just works. Double click on the solution file and you are in an emulator looking at the controls. Since you have the source code for every control, it’s a matter of copying/pasting the code in your project to get it to work. What I did, was play with the controls in the emulator until I found one I could use. Then I looked at the Visual Studio solution and found the Page that contained the control. Mindscape makes this very easy to do with their layout: So, the one that I was interested in was the Looping List Box.  Here is a demo of it: I wanted to see how they were populating the numbers 1-100 so I found the code behind and noticed it was just this one line. LoopingListBox1.DataSource = new NumericDataSource() { MinValue = 1, MaxValue = 100 }; In case you are wondering, the NumericDataSource was created by MindScape and you can view the Declaration to find out more about it:   So, the controls are pretty much that easy to use. Play with the emulator and find the control you want to use. Find the XAML file in the Sample Solution and copy/paste the code. Let’s go ahead and take a look at the controls available: They also have a great variety of Charting controls: Overall it’s a nice set of WP7 controls. Feel free to leave a comment below on anything you would like to see and I will make sure that Mindscape HQ get the message. Don’t forget if you are the first 100 people reading this article then you will get a free license.  Subscribe to my feed CodeProject

  • How to get selected values from a dynamically created DropDownList Array after PostBack (Button Click)

    - by user739280
    I have a CheckBoxList that contains Employee Names on a Wizard Step. When employees are selected and the active step is changed, the Wizard1_ActiveStepChanged function is called and it dynamically creates a DropDownList Array for each employee that is selected. Each DropDownList specifies a condition of the employee. The DropDownList is created properly. When the user clicks submit, the DropDownList array is deleted and no selected values can be pulled from the array. I understand this is an issue with the PostBack and can be fixed with ViewState, but I am trying to figure out what I can do to fix it. ViewState is enabled for the checkboxlist and the DropDownList. This is what I have in the body of my System.Web.UI.Page class private int empcount; private DropDownList[] DDL_Emp { get { return (DropDownList[])ViewState["DDL_Emp"]; } set { ViewState["DDL_Emp"] = value; } } The relevant code: protected void Wizard1_ActiveStepChanged(object sender, EventArgs e) { if (Request.QueryString["type"] == "Accident" && BulletedList1.Items.Count > 0) { this.empcount = 0; for (int i = 0; i < CBL_EmpInvolved.Items.Count; i++) { if (CBL_EmpInvolved.Items[i].Selected) { this.empcount++; } } if(this.empcount > 0) { this.DDL_Emp = new DropDownList[this.empcount]; for (int i = 0, j=0; i < CBL_EmpInvolved.Items.Count; i++) { if (CBL_EmpInvolved.Items[i].Selected) { List<ListItem> cond = new List<ListItem>(); cond.Add(new ListItem("Disabled", CBL_EmpInvolved.Items[i].Value)); cond.Add(new ListItem("Diseased - Fatality", CBL_EmpInvolved.Items[i].Value)); cond.Add(new ListItem("On Treatment - Short Term Disability", CBL_EmpInvolved.Items[i].Value)); cond.Add(new ListItem("On Treatment - Long Term Disability", CBL_EmpInvolved.Items[i].Value)); cond.Add(new ListItem("Treated - Back to Work", CBL_EmpInvolved.Items[i].Value)); cond.Add(new ListItem("Treated - Relocated", CBL_EmpInvolved.Items[i].Value)); cond.Add(new ListItem("Treated - Transferred", CBL_EmpInvolved.Items[i].Value)); this.DDL_Emp[j] = new DropDownList(); this.DDL_Emp[j].ID = "DD_LabCondition_" + CBL_EmpInvolved.Items[i].Value; this.DDL_Emp[j].EnableViewState = true; this.DDL_Emp[j].Visible = true; this.DDL_Emp[j].Items.AddRange(cond.ToArray()); this.DDL_Emp[j].Items.Insert(0, new ListItem("-- Select condition of employee: " + CBL_EmpInvolved.Items[i].Text, "")); PH_LabCondition.Controls.Add(this.DDL_Emp[j]); j++; } } PH_LabCondition.Visible = true; MV_LabCondition.Visible = true; Label1_ReportTitle.Text += "Control Count: " + PH_LabCondition.Controls.Count.ToString(); } MV_LabCondition.ActiveViewIndex = 1; MV_LostTime.ActiveViewIndex = 1; } } This code is giving me the following error now: Type 'System.Web.UI.WebControls.DropDownList' in Assembly 'System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' is not marked as serializable. I've tried changing buttons to images, playing with the AutoPostBack feature. I'm lost on how to get my dropdownlist array saved to the ViewState and accessing it after the postback.

  • Why do so many wpf controls implement CLR properties instead of dependency properties ?

    - by msfanboy
    Hello, is it because the controls programmers are lazy, too hard to implement or not knowledgeable? Wether they are custom controls from 3rd party vendors or Microsoft itself, very much controls have often clr properties instead of DP. Result is I can not bind to them and is wpf not all about binding? :/ My next side question would be, why do so many wpf controls offer visual parts but they are not member of the visual tree ? see wpf datagrid columns, headers... What do you think?
