I have a repeater with which I want to use to show a user control multiple times, populated with dataCurrently, I have this:
<asp:Repeater runat="server" ID="MyRepeater" >
<ItemTemplate>
<uc1:MyItems ID="MyItems1" runat="server" />
</ItemTemplate>
</asp:Repeater>
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?
I am using a repeater control and i want to use one more repeater control inside the existing repeater control .
Like this:
<asp:Repeater ID="Repeater1" runat="server"> <HeaderTemplate> </HeaderTemplate>
<ItemTemplate>
<!-- start child repeater --> Here I want to use one repater control <!-- end child repeater -->
</ItemTemplate>
</asp:Repeater>
I have a Repeater control that loads instances of a custom control I have built. This repeater looks like this:
<asp:Repeater ID="myRepeater" runat="server" OnLoad="myRepeater_Load">
<HeaderTemplate>
<table border="0" cellpadding="0" cellspacing="0">
</HeaderTemplate>
<ItemTemplate>
<tr><td><my:CustomControl ID="myControl" runat="server"
OnLoad="myControl_Load" />
</td></tr>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>
I bind to the Repeater through the myRepeater_Load event handler. My custom control is used to render an item within the Repeater. Because of this, I am trying to set properties on the custom control during the myControl_Load event handler. However, I do not know how to access the current item during the myControl_Load event.
Is there a way I can pass along the current item or access the current item during the myControl_Load event? If so, how?
I have a user control that contains a modal popup extender.
I am using the user control inside of a repeater so it could be shown multiple times on a page.
Everything works fine if the repeater only contains one item.
When there are multiple user controls on the page I get the following error:
"Microsoft JScript runtime error: Sys.InvalidOperationException: Two components with the same id 'PosAdjPopup' can't be added to the application."
How do I get my user control to work with the modal popup extender when it will be used multiple times on a page?
Can I keep the modal popup extender in the user control or do I have to put it on my aspx page and trap the event on the button click?
Relevant code from DetailsBERS.ascx file:
<%@ Register Src="BERS.ascx" TagName="BERS" TagPrefix="ucBERS" %>
<asp:Repeater ID="repeatBERS" runat="server"><ItemTemplate>
<tr>
<td id="Td1" runat="server">
<asp:TextBox runat="server" ID="txtTest" Text='<%#DataBinder.Eval(Container, "DataItem.id_bers")%>' MaxLength='<%#DataBinder.Eval(Container, "DataItem.id_bers")%>' />
<ucBERS:BERS ID="ucBERS" runat="server" IdBers='<%#DataBinder.Eval(Container, "DataItem.id_bers")%>' />
</td>
</tr>
</ItemTemplate></asp:Repeater>

I have a simple user control that I have placed inside a repeater. I want to access it through the ItemDataBound event of the repeater. Here's my code so far:
[Code]....
Not so sure what to do about all of this. I have developed a simple calendar using an XML doc and a repeater. The parent repeater contains a child repeater that lists events based on the date. I have a User Control that has some unique capablities for control the date in a link button. I want the user to click on the User Control and be able to use the information to do something. Bottom line, I want to access the linkbutton inside the repeater.
I have a user control that contains a repeater. We have added some paging and sorting into the user control and it all works well.
What I need now is a nice way to catch the OnItemDataBound event of the inner repeater and then bubble it up to be accessible directly from the user control from within the page.
We have tried catching it and then declaring it in the user control but it just won't work.
I am using Linkbutton inside the Repeater Control to display the paging ........and m calling Page change event on client click ....m attaching u code that m using it work fine in some webform but somewhere it didn't go the page change method on clicking page no. .....
I am writing ds code in source code of page......
<asp:Repeater ID="rptPager" runat="server">
<ItemTemplate>
asp:LinkButton ID="lnkPage" runat="server" Text='<%#Eval("Text") %>' CommandArgument='<%# Eval("Value") %>'
Enabled='<%# Eval("Enabled") %>' OnClick="Page_Changed" CssClass='<%# Convert.ToBoolean(
Eval("Enabled")) == true ? "LBR" : "Active" %>'>></asp:LinkButton></ItemTemplate>
</asp:Repeater>
I have a user control inside a repeater. I am binding a collection of objects to the repeater.
My user control has a public property to retrieve the object (setobject)
How do i pass each object through to the user control and not just the object property value? What is the syntax to do this?

I want to bind parent repeater item index in child repeater control using inline code not code behind side.
For example
[Code]....
I have written a user control that captures some user input and has a Save button to save it to the DB. I use a repeater to render a number of these controls on the page - imagine a list of multiple choice questions with a Save button by each question.
I am loading the user control inside the repeater's ItemDataBound event like this (code simplified):
[code]....
The problem is that when the Save button is clicked, the page posts back, but lbnUpdate_Click is not called. The Page_Load event of the page itself is called however.
I should mention that the repeater is part of a user control, and that user control is loaded inside another user control (this is a DotNetNuke site which makes heavy use of user controls). The Save button link looks like this:
javascript:__doPostBack('dnn$ctr498$AssignmentsList$rptAssignments$ctl04$ctl00$lbnUpdate','')
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 don't think I understand fully how ASP.NET does inheritance of controls.I have a user control, ucBase, which has an asp.net label in the ascx file. Code behind references the label and it works fine during run time if the control is not a parent for another user parent.
If I have another user control, ucChild, inheriting from ucBase, the label in ucBase's code is always null. ucChild has no controls in its ascx fileThe server controls (like the label) needs to be declared in the ascx file and not created programmatically.What needs to be done for ucBase to see its own controls when it's a parent user control?
I've got a web site that has a master page and that master page (mpMaster that has a user control ucControl1) which has a sub user control (ucControl2), this user control has a property which accepts a value. Now, I have a page that uses the master page
and on this page I have another user control (ucPageControl), I need to find a way of setting the value in ucControl2 from ucPageControl. Is this possible at all?

I have a web user control that represents a simple message box. It is used to display simple messages like "Item has been deleted", or "The item was saved successfully".
On the other hand, I have another web user control that represents the item in the form of an editable form (I made this a user control because this is used in two different pages). I want to embed an instance of the message box user control inside the editable form. I am writing this right after the @Control directive:
[Code]....
Instead of using @Register directives, I register the user controls in web.config and so far this has worked just fine.
With the above markup, the project compiles, but whenever I try to navigate to a page that contains this construct, I get an HttpParseException exception. Furthermore, Visual Studio states that the tack w7rc9:MessageBox doesn't represent a known control.
What am I doing wrong?
