I have added the one checkbox colum in the grid. I would like to make that column editbale and rest of the columns are not. how to make it ?, At the same time I want to capture the  checkbox state changed event.

FYI : I am using the following code to add checkbox column

GridViewCheckBoxColumn checkBoxColumn = new GridViewCheckBoxColumn();

checkBoxColumn.DataType =

typeof(bool);

checkBoxColumn.HeaderText =

string.Empty;

checkBoxColumn.Width = 25;

dGridDisplayField.MasterGridViewTemplate.Columns.Insert(0, checkBoxColumn);

Thanks you
Raghu
