Hi Telerik,
I have a Radgridview with combo box column . consider i have 3 rows.
in  the first row am selecting some value like "x" from the combobox column ,
 then when i select the  same value "x" in the second row , i should say the value x is already selected
 i guess we have to loop the columns across the gridview .... could anybody provide some idea

Thanks in Advance
Dev

Hello

Yes, you would need to itterate over teh rows to find the values. (see this help topic) you may also find this help topic on data validation of use.

Hello,

As you have suggested, you can stop rows from being resized by setting the AllowRowResize property to false.
this.radGridView1.AllowRowResize = false;

You can also control how the enter key behaves in terms of adding and editing rows. E.g.
this.radGridView1.NewRowEnterKeyMode = RadGridViewNewRowEnterKeyMode.None;

Please remember to mark the original answer to your first question as answer and if you need further help, please let me know
Regards,
Richard
