I am using the latest version, and never used GridClientSelectColumn before. I could not find this column among the list of different columns that are to be selected at design-time. How shall I include this column in the grid.
The GridClientSelectColumn is not included to the column collection in the editor, as only data bound columns appear there. You can modify the markup in the aspx page to add a GridClientSelectColumn yourself. GridClientSelectColumn is deprectated?
