Hello dhamodharan,

You can redirect the page after insertion. This way when hitting F5, the data will not be inserted second time.

If you have page MyPage.aspx that contains RadGrid, for instance:

Attach function to ItemInserted event of the grid

<telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1" oniteminserted="RadGrid1_ItemInserted" .....>
   ....
</telerik:RadGrid>

Then on ItemInserted event, redirect to the same page.

protected void RadGrid1_ItemInserted(object sender, Telerik.Web.UI.GridInsertedEventArgs e)
{
    Response.Redirect("MyPage.aspx");
}
