Hello Sunil,

Thank you for posting your inquiry to the Infragistics ASP.NET forums.  When binding a large amount of data to the UltraWebGrid, the best approach is to use Partial DataBinding, where only a subset of the bound data is retrieved for display.

In the information regarding Partial Data Binding found in the following link to the Infragistics NetAdvantage Online Help for ASP.NET, it explains how a subset of data is initially loaded and retrieved each time the UltraWebGrid scrolls out of the loaded rows range, giving the developer total control on the number of rows to retrieve:

         Partial Data Binding 
         <https://ko.infragistics.com/help/aspnet/webhierarchicaldatagrid-data-binding>

Information and sample code may be found in the above link, demonstrating the functionality of Partial Data Binding.  Please take a look at the provided information and let me know if you have any questions.

Thank you.

Sincerely,
