Question

I have a gridview that contains 4 columns of check boxes. By default it is not possible to check or uncheck them.

How can I go about to make only one of the columns of checkboxes editable…i.o.w. not read only so that I can check or uncheck the one specific column of check box which will update the database.

You can use RowDataBound event to apply enable/disable criteria on the checkboxes using row instances of grid view along with the binding data.

void gridview1_RowDataBound(object sender, GridViewRowEventArgs e)
{
  if (e.Row.RowType == DataControlRowType.DataRow)
  {
       CheckBox chk = (CheckBox)e.Row.FindControl("chkBoxID");
       if(DataBinder.Eval(e.Row.DataItem, "datasourceColumnName").ToString() == "someval")
             chk.Enabled = false;
  }
}
