I have a hierarchical RadListView:
<telerik:RadListView ID="RadListView1" runat="server" DataSourceID="SqlDataSource0"...>
......
 <ItemTemplate>

<%

 

# Session["CatalogID"] = Eval("SerialsID").ToString()%>

 

 

 

<telerik:RadListView ID="RadListView2" runat="server" DataSourceID="SqlDataSource1"...>
.....
<ItemTemplate>
<%# Session["ProductID"] = Eval("ProductID").ToString()%>

 

 

<asp:Button runat="server" ID="btnRebind_Production" Text="" OnClientClick="somefunction"/>

 

 

 

 

<telerik:RadListView ID="RadListView3" runat="server" DataSourceID="SqlDataSource2"...>
....
<ItemTemplate>
<div>

<asp:Button runat="server" ID="btnRebind_Detail" Text="" OnClientClick="somefunction()/>

 

 

 

 

 

<asp:ImageButton runat="server" ID="img1" AlternateText="" CausesValidation="false" ImageUrl='<%# Eval("ImageURL") %>' Width="180px" Height="180px" />
<div>
</
ItemTemplate>

 

 

 

</telerik:RadListView>
</ItemTemplate>
</telerik:RadListView>
</ItemTemplate>
</telerik:RadListView>
When I click btnRebind_Detail, I only want to rebind RadListView 3. The problem was that when I call

$find(

 

"<%= RadListView1.ClientID %>").rebind(), the data sets for RadListView2 and 3 are wrong.  I tried to wrap the RadListView3 with UpdatePanel and call _doPostBack("UpdatePanel1", ' '), but the dataset for RadListView 3 is wrong, it populated the ListView3 with another Catalog's details.  Is there a way to only rebind certain child RadListView in Client-Side?

Hi Shannnon,

It seems like the SqlDataSource is not correctly picking the data in this scenario. It might be a better idea to try with advanced data-binding. Instead of the declarative datasources use the NeedDataSource event, where you can manually check the ProductID value of the parent data item and query the DB using it.

Kind regards,
