Using Q12009 RadGrid, C#, VS2008, SQL Server. I have several pages where the autogenerated popup editor takes a long time to appear. I think this might have to do with two GridDropDownColumns(RadComboBox Type). One of these have several hundred possible choices and the other has a few thousand choices. Using Fiddler I can see it is xmitting all of the DropDownList Values and Text for these comboboxes before the page appears. How could I implement some type of incremental loading of the data in the combo box for these autogenerated popup edit fields?

Hello John,
Thank you for the explanation. To speed up the performance, you may consider implementing load on demand for the RadComboBox editors by replacing the GridDropDownColumns with template columns hosting RadComboBoxes inside their edit templates.
A sample implemenatation can be found in the KB article linked below:
