I have a GridViewTextBoxColumn in my grid. I want it to behave like a drop down when I have more than one potential value which could be displayed. In order to do this I capture the "EditorRequired" event. Sometimes I will have values in my grid for a given row and sometimes I will not. Sometimes I will have only one item in the row as well. So basically I expect to have no value, one value or multiple values.
I'd like the column in my GridView to only show the drop down list when I have more than one value that is available. Currently the column shows the drop down as soon as I click on that column which is very misleading to the user. I've attached 3 screen shots showing an example of how my grid row/column appears. In my screen shots I also show an exclamation point image when there is more than 1 item in my drop down list.
Here is my implementation of this event..
Also, it would be nice for the border of the column to have a thickness and color before clicking on it when it has multiple values in the drop down. If possible please let me know how to do this.
