I've created a Gridview and i'm populating, editing and deleting okay. However the width of the columns changes depending on what data is in the cell. I've tried setting the individual columns ItemStyle and setting the width but it only seems to effect how the gridview in design view and not when the application is running. When i populate the cell with data the column resizes to fit the data.

Is there any way i can set the max length of a column in single row mode?
