First of all in markup use Text property of label, do not put databinder.Eval in
<asp:Label ..> do not put content here </asp:Label>
In item databound event first find out control in which template.
follow this example :
Markup:
<asp:Repeater ID="Repeater1" runat="server"
onitemdatabound="Repeater1_ItemDataBound">
<HeaderTemplate>
</HeaderTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Eval("content") %>'></asp:Label>
<asp:LinkButton ID="LinkButton1" runat="server">LinkButton</asp:LinkButton>
</ItemTemplate>
<AlternatingItemTemplate></AlternatingItemTemplate>
<SeparatorTemplate></SeparatorTemplate>
</asp:Repeater>
Source Code :
C#:
protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item)
{
Label lbl = (Label)e.Item.FindControl("Label1");
LinkButton link = (LinkButton)e.Item.FindControl("LinkButton1");
link.PostBackUrl = "abcd/" + lbl.Text;
}
}
VB.Net:
Protected Sub Repeater1_ItemDataBound(sender As Object, e As RepeaterItemEventArgs)
If e.Item.ItemType = ListItemType.Item Then
Dim lbl As Label = DirectCast(e.Item.FindControl("Label1"), Label)
Dim link As LinkButton = DirectCast(e.Item.FindControl("LinkButton1"), LinkButton)
link.PostBackUrl = "abcd/" + lbl.Text
End If
End Sub
