Telerik Grid Hierarchy: Details Grid Paging not working

[Mohamed]

Telerik Grid Hierarchy: Details Grid Paging runs the paging of the main grid,

i.e, when I click on the page 2 in the details grid, the main grid show the second page

i want to keep the main grid as it's and show the second page of the detail grid.

This is my code

<telerik:RadGrid ID="gridPinHistory" runat="server" AllowFilteringByColumn="True"

AllowPaging="True" PageSize="20" AllowSorting="True" AutoGenerateColumns="False"

CellSpacing="0" GridLines="None" Skin="Office2007" OnPageIndexChanged="gridPinHistory_PageIndexChanged"

AllowCustomPaging="false" OnNeedDataSource="gridPinHistory_NeedDataSource" OnDetailTableDataBind="gridPinHistory_DetailTableDataBind">

   <MasterTableView TableLayout="Auto" DataKeyNames="PIN">

       <telerik:GridTemplateColumn HeaderText="PIN" DataField="PIN" AllowFiltering="true">

         <ItemTemplate>

           <asp:LinkButton ID="lbtnSearchCustomer2" runat="server" Text='<%# Eval("PIN") %>'

           OnClientClick="" />

         </ItemTemplate>

Hi Mohamed,

The behavior you experience is expected. Because no matter which GridTableView is paged, you are changing the CurrentPageIndex of the grid which will affect the MasterTableView. Therefore I suggest that you remove the code from the PageIndexChanged event.
Note that when the grid is bound through the NeedDataSource, you do not need to call the DataBind method for it or set its DataSource outside the NeedDataSource event handler. In this case it will automatically handle paging, sorting, filter, etc. Furthermore, when you have hierarchical grid bound programmatically, through the NeedDataSource and DetailTableDataBind event you do not need to set any ParentTableRelations. They are used only when the grid is bound though declarative DataSource controls like SlqDataSource, LinqDataSource, etc.

Check this demo for more information.
