I have a repeater with a checkbox and a textbox, that I am binding to a datasource. Depending on conditions from the code behind, I want to be able to disable the checkbox and textbox dynamically.
Currently this is what I have within the
[Code]...
The #DataBinder.Eval(Container.DataItem, "DISABLE") is being set to the string value of "true" on the code behind yet when the code is ran, I recieve a InvalidCastException error.
I am using a repeater control and i want to use one more repeater control inside the existing repeater control .
Like this:

<ItemTemplate>
<!-- start child repeater --> Here I want to use one repater control <!-- end child repeater -->
</ItemTemplate>
</asp:Repeater>

I have dropdownlists inside a repeater. I would like to do something like this but can't figure out the syntax:
If (DropDownList1.Text = "Hello")
{ DropDownList1.Enabled = false; }
I'm not sure if the JQuery implementation will be as simple as this, or the approach will be a little different?
how can i enable and disable columns in repeater in the code behind
View 1 RepliesI want to bind parent repeater item index in child repeater control using inline code not code behind side.
For example
[Code]....
Edit: I have a working solution already - I would just like to know why my original attempt didn't work. My original attempt is the code below.
I'm using the approach I found here:[URL] 306154 to implement a nested Repeater. Each parent item has one or more children items (the point of having the nested Repeater) with a dropdown horizontally aligned to each child item. In an effort to re-use the nested part of the Repeater I wanted to develop that piece as a user control but couldn't get it to work. I am wondering if it is even possible and if so how?
Here is my user control apsx:
<asp:Repeater ID="NestedRepeater" runat="server">
....
<ItemTemplate>
<tr class="text" id="RepeaterItemRow" runat="server">
<td>
<%#DataBinder.Eval(Container.DataItem, "Name") %>
</td>
<td>
</td>
<td>
</td>
<td>
</td>
<td>
</td>
<td>
</td>
</tr>
</ItemTemplate>
And here is my code behind for the user control. I noticed when I debugged NestedDataSource was null even though in the parent page load the data is there:
public DataSet NestedDataSource
{
get;
set;
}
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
NestedRepeater.DataSource = NestedDataSource;
NestedRepeater.DataBind();
}
}
In the parent Repeater in the `<ItemTemplate> I have:
<asp:RepUC ID="NestRep" runat="server" NestedDataSource='<%#((DataRowView)Container.DataItem).Row.GetChildRows("nestedrel") %>'>
And finally the page code behind:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BuildWBS();
}
}
private void BuildPage()
{
DataSet ds = new DataSet();
ds = DataAccessLayer.GetData("System");
ds.Relations.Add("nestedrel", ds.Tables[0].Columns["Id"], ds.Tables[1].Columns["ParentId"]);
ParentRepeater.DataSource = ds;
ParentRepeater.DataBind();
}
The page loads but nothing relating to the repeater appears on the screen. So, can you see anything wrong with what I have? Is the way I tried doing this even possible?
lets say I want to make a label of repeater1 visible in repater2's ItemCommand() method..
e.Item.FindControl("rpt1Label").Visible=True;
is not working..how else do you do it ?
[EDIT]
changed that to repeater1.FindControl("rpt1Label").Visible=True;
This is throwing object reference null exception
If I have a custom user control (say, MyCustomControl.ascx) which contains a number of other controls including a repeater, is there any way to expose that repeater's templates as templates for MyCustomControl?
For example, I would want to be able to do this:
[code]....
There could potentially be more than one repeater or other templated controls within the parent control, in which case I would like to be able to expose all of those templates for all of the controls in the same way.
My first thought was to simply expose the repeater's templates as ITemplate properties on MyCustomControl, but that didn't work since there's no (obvious) way to access the repeater's DataItem from the templates doing it that way.

I have set the EnableViewState property to false, but when I click on the button the value in the textbox persists after the postback. Why does the value persist?
