Question

I have a repeater bind by the data coming from database. Now on click of its row i want to bind another repeater of detailed information.One thing more both are not nested.
OK Let me explain with an example, I have a repeater of classes. This repeater has binding information about all classes in school.Now I have another Repeater for detailed information of a particular class.Now when i click on a particular class in list of classes, then i will get the detailed information i.e. bind the second repeater using the class id.

Ok..So you know the particular id of row which the user clicks.In the click event get the id and pass it to your stored procedure or what ever way you are binding to the repeater.check this below..

<asp:Repeater ID="repGrd" runat="server">
<ItemTemplate>      
          <asp:LinkButton ID="lnkbtn" Runat="server" RowID='<%#DataBinder.Eval(Container.DataItem,"ID")%>' OnCommand="clickbutton">Click Here</asp:LinkButton>
</ItemTemplate>
</asp:Repeater>

and the code behind goes like this..

 #region On click of row binding repeater
    public void clickbutton(Object sender,CommandEventArgs e)
    {
    try
    {
            //Getting the ID of clicked row
            string RowIDval=((LinkButton)sender).Attributes["RowID"].ToString().Trim();

        // Write your code here to bind the repeater as you got the ID
    }
    catch(Exception ex)
    {

    }
    }
    #endregion

Try this out.
