I have a TreeView control inside a repeater control. I try to bind the data to it using this syntax but it errors out:
<asp:TreeView
ID="tvChainAccounts_Off"
runat="server"
Enabled="false" DataSource=
<%#DataBinder.Eval(((RepeaterItem)Container).DataItem,
"tvChain")%>
></asp:TreeView>
where tvChain is a property of type TreeView.
i have a TreeView inside a Repeater, i am not sure how to get the OnSelectedNodeChanged item ie
protected void tvAssets_Change(object sender, EventArgs e)
{
selectedItemId = ???
}
I am new to ASP.NET, trying to learn it. I am using ASP.NET 3.5 with VB for scripting. Also read some books. I just can't figure out how to bind a DropDown List inside a Repeater Control. I saw a few examples but none were clear enough and explained all the details. I want to populate the Drop-Down using values from a Database inside the repeater.
I also read this article [URL] but still can't understand how to bind dropdown in a repeater.
I want to display 2 things inside the Repeater Control.
1. User Selected Values (which comes in the form of an Arraylist) from a previous page using "PostBackUrl" method.
2. Then allow users to select values from a Dropdown list corresponding to each design code they selected on previous page. (the dropdown values here must come from a backend db)
Also, I want to control the number or rows displayed inside the repeater control. It should be equal to the number of "design codes" selected by the user on a previous page.
Here is my code so far ....
ASPX Code:
<body>

Collection<ParameterDetailDTO> clParameterDetailDTO = objMonitoringDataInfo.GetAllParameters(idList, out errorCode);
var parameters = (from resx in clParameterDetailDTO
select resx.ParameterType).Distinct();
Repeater1.DataSource = parameters.ToList();
Repeater1.DataBind();
counter = Repeater1.Items.Count;
while (i < counter - 1)
{
foreach (var parType in parameters)
{
var items = from resx in clParameterDetailDTO
where resx.ParameterType.ToLower().Contains(parType.ToLower())
select new { resx.ParameterName, resx.ParameterID };
((CheckBoxList)(Repeater1.Items[i].FindControl("chkParList"))).DataSource = items;
((CheckBoxList)(Repeater1.Items[i].FindControl("chkParList"))).DataTextField = "ParameterName";
((CheckBoxList)(Repeater1.Items[i].FindControl("chkParList"))).DataValueField = "ParameterID";
((CheckBoxList)(Repeater1.Items[i].FindControl("chkParList"))).DataBind();
}
i++;
}
I am using LINQ as datasource.

View 3 RepliesI have a user control that displays a shopping cart in an ecommerce application.
The main cart display is a repeater that renders as a html table. In one of those table columns, there is another repeater to display people associated with the products int he cart (it's a repeater in case there is a line item >1 with multiple people).
I've added an ImageButton that I want to use to change the person associated with the item. At first, when I'd click on it I was getting this error:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
So as an experiment I disabled EventValidation on the page (not the control it's self) and now I do not get an error, but I also do not ever hit the breakpoint I set in the innermost repeater's ItemCommand event.
So I wonder how I might do this without disabling EventValidation, because this control will show up on multiple pages and we don't want to edit them all. Also, I'll need to know not only the repeater containing the control's row that the event came from but also the row index of the repeater containg this one. Is this possible?

View 2 RepliesI am using Nested Repeater repeater1 and repeater2 in my project . one button is there inside repeater2 but i cant use that button using e.commandname
so how to use that button and how to write code on it.
what changed do I need to make to my code for it to achieve what I'm after.
At the moment I am getting a "cannot cast to type" error message with the below code.
I have also tried calling the ItemDataBound method in with the parent repeater tags and had no errors but when I clicked on the button it would just move back to the top of the page and would not hide or show any data. Also I have made the div style to none but the first record still shows its child but the rest don't.

Apparently I am trying to do something that is a little unorthadox here. I am trying to use multiple arrays and bind them to one repeater in C#. I would think that there has to be a reasonably easy way to do this but I can not seem to find it anywhere online. This is what I have so far (that works). How do I bind multiple arrays to this one repeater though?
// Bind Array to Repeater repTest.DataSource = arrTest1; repTest.DataBind();
<form id="formTest" method="post" runat="server">
<asp:Repeater ID="repTest" runat="server"> <HeaderTemplate>
<table border="0" cellpadding="0" cellspacing="0" width="100%">
</HeaderTemplate> <ItemTemplate> <tr height="30px">

</ItemTemplate> <FooterTemplate> </table> </FooterTemplate>

I would like to display contents of two (or more) tables inside a Repeater control grouped by some Category. I will be getting the data in sepatare DataReaders (not a single joined query). Is there a way to do this without resorting to building DataTables/DataSets ? I am aware of nested repeater techniques, just not sure how to relate the data with DataReaders.
