Hi Milko,

What I mean is when I resize the column of the grid. The width of my custom editor should be adjusted based on the new width of column.

Actually, I found out the problem. I did not implement the {PropertyName}Changed event. Add that to my custom editor and it works.

Another issue is my custom editor size does not fit the size of the column. Can you show me the way to make custom editor always fit to the cell?

Hi Milko,

I have successfully create a custom editor using UltraControlContainerEditor. But I got an issue, when I tab out of the grid, the value of the cell is blank. I don't set the RenderingControl property, I just set EditingControl. EditingControlPropertyName will point to a property which is a DateTime? type.

Not sure if I miss anything?
