[Solved] First row loses dropdown bound value when using GridDropDownListColumnEditor

[Chris]

Hi,

 I am using the Q1 2009 RAD AJAX control for ASP.NET. I hvae an odd problem when using a GridDropDownListColumnEditor to modify the width of the dropdownbox in edit mode. When the grid is not in edit mode the first row does not display a value for the field that is bound to the dropdown column. The value is correctly picked up in edit mode and in all the other rows. If i remove the column editor ID from the dropdown column all the values are displayed as expected.

The GridTextBoxColumnEditor works as expected.

Thanks

Chris
