C# - Creating Server Controls Dynamically At Runtime Inside A Grid Item Template?
Aug 6, 2010
I've an item template inside a grid which has a <asp:LinkButton/> inside it. I assign the text for the link button as
<%# Convert.ToString(Eval("Tags"))%>
Tags can have a string with multiple tags in it delimited by space. For eg. "sports", "sports cricket", "sports cricket sachin" are the examples of some possible tags.
I want to create a button for each tag inside the string. How can i create the controls (server control - linkbutton) dynamically during runtime inside the grid item template?

I'm having problems binding controls at runtime. I've some user controls which need to be bind to the page when one of the dropdownlist selected index changed.
I can able to bind them properly but when if there is any postback event happens I am losing the controls and control values which were created runtime.
How do I avoid binding them again and again.

I have a gridview, in an update panel, that's populated by an object data source when the page loads. This same Grid View is going to use a different data source and slightly different columns collection at runtime. The columns collection will be very similar, with one column added and three removed. Is this the best way to do this?
The other solution would be to create another grid view and data source to use when needed. The two Grid Views can be toggled off and on to use the correct one as needed. I've done this and it worked well, as far as I can tell. I'm curious if there are performance implications because of the additional Grid views and data sources. Or, if there are other reasons not to do this.
Which of these two ways is the best way to do this? Should I toggle between the two Grid Views at runtime or modify the grid view(datasource and columns) at runtime in the code behind?

I have a gridview that I want to show a dropdownlist (for, let's say, column1) when it has a certain value, and I want to change that same column into a label when it has a certain value. Is this possible with gridview? if so, how?

I have the below label. I need it to be a link that will cause the following:
Existing label INSIDE a DataList Item Template;
<asp:Label ID="Label10" runat="server" Text='<%# Eval("CG_ID") %>' Font-Size="X-Small"></asp:Label>
I need to change this label to a link that will cause C# code behind to:
tbxCG_ID.Text = Eval("CG_ID")
and then call this:
protected void ListBox1_SelectedValueChanged(object sender, EventArgs e)
I keep creating a DataList1_SelectedIndex_Changed event created when I double click the label or a link button. What is the code needed? I can see the Eval("CG_ID") value with the label but I don't know how to get it into tbxCG_ID.Text and fire the ListBox1 event.

I have written some code to dynamically generate template columns for gridview which works well. However, each cell in the gridview has to be a linkbutton, which when clicked does a db update and redirects to a specific url with some parameters in it.
I have attached a click event handler to the linkbutton in the InstantiateIn method but the event does not seem to fire.

protected void btnAnalyze_Click(object sender, EventArgs e)

Newbie in using AJAX . Programming in C# and using SQL as a database. Here is my scenario. User selects a project and I want to display the subprojects related to that project. Here is the query I use to retrieve subprojects.
"SELECT SubProjectName,StartDate,Description FROM SubProject WHERE ProjectName'"+ddlProjectName.text+"';
Currently I store the results of the query in a Dataset. I want to get the SubProjectName in the Header of the Accordion and StartDate and Description values to the text box for each accordion. ( This is what I need to do in each accordian for each subproject)
<asp:AccordionPane ID="AccordionPane2" runat="server">
<Header>
<a href="" onclick="return false;" class="accordionLink">SubProject 1</a>
</Header>
<Content>
<table width="100%" cellpadding="0" cellspacing="0">
<tr>
<td class="td_left" colspan="2">
<asp:Label ID="Label1" runat="server" Text="Start Date"></asp:Label>
</td>
<td class="td_left" colspan="2">
<asp:TextBox ID="StartDate" runat="server"></asp:TextBox>
</td>
</tr>
<tr>
<td class="td_left" colspan="2">
<asp:Label ID="Label2" runat="server" Text="Description"></asp:Label>
</td>
<td class="td_left" colspan="2">
<asp:TextBox ID="txtDecription" runat="server"></asp:TextBox>
</td>
</tr>
</table>
</Content>
</asp:AccordionPane>
How can I do this? Some code example would be great on how to creat the accordinas ,text boxes dynamically and fill the values.

I have a requirement whereby one or more image buttons need to be created in a user control at runtime. The number of buttons is determined from a database where a user can add one or more rows that contain an image for each button, so if a user adds 3 images to a table, 3 image buttons are created. Ive used this code but I get an error at runtime
The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases.
[Code]....
this is the usercontrol aspx
[Code]....
I basically want one or more buttons to render within the div in the usercontrol. Ive only got the code written for one button at the moment while I test the rendering, eventually they will be rendered in a loop of records taken from a database. Whats the best way to do this ?

OK, so I'm trying to create a template item from a web form.
I have referenced this article: [URL] and it exports the template and installs it fine.
When you try and use the template item within a project though it leaves the inherits="_Default" in the page directive like shown below:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="FormTemplateDev.aspx.cs" Inherits="_Default" %>
So it thinks all the new template items use the original form name pre-template generation. This is an issue in the code behind too as shown here:
public partial class _Default : System.Web.UI.Page
I have seen example of passing paramater strings through but havent managed to get anything to compile. I found something like below:
public partial class $safeitemname$ : System.Web.UI.Page
This was the link to the list of available template parameters i found:

I have ASPxDataView and ASPxRadioButtonList within item template. i also have two SQLDataSource's (first fill ASPxDataView, second ASPxRadioButtonList). They are using other database tables connected with the foreign key. Is there any way to pass parameter to my second sqlDataSource (id) to fill RadioButtonList property ? i mean select * from TABLE2 where id = @id ; (@id is a value from TABLE1 which is a value of column returned by first sqlDataSource)

I added a (Read More...) Div to my repeater's item template, that doesn't contain any information.
I want to add a text button or an anchor to my item template..when it's clicked it should call a javascript method that writes information to the Div and it will take the content to write as a parameter, the content will be passed as an Eval method, for example it will eval("education")...and when it's clicked again it will hide the Div
I tried various and near approaches but it all worked outside the repeater and item template tags, but if I placed the identical code to the repeater and my javascript to the head tag it won't function!
I don't want to post my code, because I'm sure it's an easy and essential trick for any developer...so I was hoping for an original example not an edit to my test code(beginners logic)

Here is a perplexing issue I have not seen a good answer to on StackOverflow, although there a couple stabs at it... I have a situation where I'd like to do this:
<asp:Repeater ID="MyRepeater" runat="server" OnItemDataBound="MyRepeater_ItemDataBound">
<ItemTemplate>
<li id="id?">
All the other stuff
</li>
</ItemTemplate>
</asp:Repeater>
is how do I get the ID of my <li> elements to be id1, id2, id3, etc., based on the ItemIndex they are bound to? So far the most... er..."elegant" solution I've come up with is to replace the <li> with an asp:Literal and dump the <li...>' text. But that just feels... so wrong. And no, I'm not using ASP.NET 4.0, which I've read will provide this functionality.

I have a formview with various templates set up for a database that has 255 columns. I need the insertitemtemplate to pre-fill values based upon a specific selection by the user (just like the edit item template) but when the template is switched to insertitemtemplate every text box is cleared. The idea is that a new entry is usually made by making minor changes to an existing entry. With 255 fields I don't want to require the user to enter every field when only three or four need to change.

I have a gridview which the columns are created programmatically.
When a button is click i will clear all columns and add the columns that I want. Im adding a boundfield which is not a problem. When I add a template field, I must add also the item template which is my problem.
How can I add a item template in the template field I created which is binded in my datasource. Also what event handler should I use to do this.
Here's the part of my code:
[Code]....
Someone know how can I bind a label item template from the datasource. The label item template should be firstname + middlename + lastname.
If im not doing it programatically, it will be just concatenating eval(). But how can create item template and bind it programmatically?
