    Hello Biju,

    Thank you for writing.

    Please refer to the Cascading ComboBoxes in RadGridView KnowledgeBase article which demonstrates a sample approach how to achieve your goal.

    I hope this information helps. Should you have further questions I would be glad to help.

    Hello Dess, 

    Thanks for the reply. I referred the link. It can be used for small list . What about this approach  for a big list. In my case it is Product and Batches to be binded. My product table will have more than 60K records and full Batch table will have more than 150K records.  This means the second column need to be binded to a huge list.

    Thanks

    Hello Biju,

    Thank you for writing back. 

    This approach is applicable for cases with 150 000 records in the GridViewComboBoxColumn as well. However, have in mind that it will affect the editor's initialization time a bit due to the number of records. Please refer to the attached gif file. 

    I hope this information helps. If you have any additional questions, please let me know.
