Hello Lasly,

I tried the same in the latest version 2011.2.712.35 which worked as expected. Make sure that you have given the fields as shown below.
aspx:

<telerik:GridDropDownColumn  DataField="EmployeeID" ListTextField="EmployeeID"ListValueField="EmployeeID" UniqueName="GridDropDownColumn" DropDownControlType="DropDownList"  DataSourceID="SqlDataSource1">
</telerik:GridDropDownColumn>

If this doesn't fix your issue, try upgrading to the latest version.

Hi thanks for the reply
I tried to use your example, but it doesn't work.
I've noticed that my version is different from your, because my version is for FW.net 4.0 while yours is for 3.5. 
The problem is version of framework?
however I've attached a printscreen of my problem.
Best regards

Hi Lasly,

The observed behavior is due to an inssue introduced in the Q2 2011 release. Please upgrade to Q3 2011 to fix the problem.
