How to persist row in editable mode in radgrid, on page size change?
Scenario:- In my radgrid i have 10 records with page size of 5 records. I am on second page to edit 3rd record(4th index).
Now I change page size from 5 to 10 and the record in edit mode changes. It takes 3rd record among 10.
Ideally 9th row should remain in edit mode.
How to achive this?

Thanks in advance

Hi Vinayak,

Please try the following code snippet.It works fine at my end.It persists the edit mode in page size change .Hope this helps.

ASPX:
<telerik:RadGrid ID="RadGrid1" runat="server"   PageSize="5" AllowAutomaticUpdates="True" AllowPaging="True"
    AutoGenerateColumns="False" DataSourceID="SqlDataSource1" OnPreRender="RadGrid1_PreRender"
    OnEditCommand="RadGrid1_EditCommand" OnPageSizeChanged="RadGrid1_PageSizeChanged">
    <PagerStyle Mode="NextPrevAndNumeric"></PagerStyle>
    <MasterTableView  CommandItemDisplay="TopAndBottom" DataKeyNames="ProductID"
        DataSourceID="SqlDataSource1" AutoGenerateColumns="False">
        <Columns>
            <telerik:GridEditCommandColumn ButtonType="ImageButton" UniqueName="EditCommandColumn">
            </telerik:GridEditCommandColumn>
            <telerik:GridBoundColumn DataField="ProductName" HeaderText="ProductName" SortExpression="ProductName"
                UniqueName="ProductName" ColumnEditorID="GridTextBoxColumnEditor1">
            </telerik:GridBoundColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

C#:
public static string dataKey = "";
   bool isPageSizeChanged = false;
   protected void RadGrid1_PreRender(object sender, EventArgs e)
   {
       if (isPageSizeChanged)
       {
           foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
           {
               string value = item.GetDataKeyValue("ProductID").ToString();
               if (value == dataKey)
               {
                   item.Edit = true;
                   break;
               }
           }
           isPageSizeChanged = false;
           RadGrid1.Rebind();
 
       }
   }
   protected void RadGrid1_EditCommand(object sender, GridCommandEventArgs e)
   {
       GridDataItem editItem = (GridDataItem)e.Item;
       dataKey = editItem.GetDataKeyValue("ProductID").ToString();
   }
   protected void RadGrid1_PageSizeChanged(object sender, GridPageSizeChangedEventArgs e)
   {
       isPageSizeChanged = true;
   }
