Hi Jyoti,

When posting a support ticket and a forum thread about the same thing, please notify us about this.

Now to your question - we are aware of the described problem and are researching for a way to prevent it. In the meantime, please use the following workaround:

    
            <%@ Page Language="C#" %> 
        
            <%@ Import Namespace="System.Data" %>

            <script runat="server"> 
        
                public string PageSizeComboBoxClientID; 
        
                protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e) 
        
                { 
        
                    DataTable dt = new DataTable();
