Can't find control within asp.net repeater?

You need to set the attribute OnItemDataBound="myFunction"

And then in your code do the following

void myFunction(object sender, RepeaterItemEventArgs e){   Label lblA = (Label)e.Item.FindControl("lblA");}

Incidentally you can use this exact same approach for nested repeaters. IE:

<asp:Repeater ID="outerRepeater" runat="server" OnItemDataBound="outerFunction"><ItemTemplate>   <asp:Repeater ID="innerRepeater" runat="server" OnItemDataBound="innerFunction">   <ItemTemplate><asp:Label ID="myLabel" runat="server" /></ItemTemplate>   </asp:Repeater></ItemTemplate></asp:Repeater>

And then in your code:

void outerFunction(object sender, RepeaterItemEventArgs e){   Repeater innerRepeater = (Repeater)e.Item.FindControl("innerRepeater");   innerRepeater.DataSource = ... // Some data source   innerRepeater.DataBind();}void innerFunction(object sender, RepeaterItemEventArgs e){   Label myLabel = (Label)e.Item.FindControl("myLabel");}

All too often I see people manually binding items on an inner repeater and they don't realize how difficult they're making things for themselves.

I just had the same problem.

We are missing the item type while looping in the items. The very first item in the repeater is the header, and header does not have the asp elements we are looking for.

Try this:

if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)    {Label lblA = (Label)rptDetails.Items[0].FindControl("lblA");}

Code for VB.net

    Protected Sub rptDetails_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles rptDetails.ItemDataBound          If e.Item.ItemType = ListItemType.AlternatingItem Or e.Item.ItemType = ListItemType.Item Then        Dim lblA As Label = CType(e.Item.FindControl("lblA"), Label)        lblA.Text = "Found it!"      End If    End Sub
