Hi,

While add new row into webgrid, webcombo does not load all the records in it.

Attached screenshot, as it works while edit the rows.

Attached sample example aspx page.

Please give us solution ASAP, I am using Version 7 of webcombo.

With WebGrid 8, just after inserting a new row, if I try to edit it, when the update code is supposed to run, I get :

Server Error in '/' Application.

Object reference not set to an instance of an object.

In the AddRow handler, I insert the new line in SQL Server. The Key is autogenerated by SQL Server.

Then I read this new Key and set in the Value of the corresponding WebGridCell in the new row.

Is there something else I need to do to correctly set the row's DataKeyField?

Thank you,
