如何将复选框列添加到gridview

Question

How to add checkbox column to gridview .

i've tried:

foreach (GridViewRow objRow in GridView1.Rows)
{
   TableCell tcCheckCell = new TableCell();
   CheckBox chkCheckBox = new CheckBox();
   tcCheckCell.Controls.Add(chkCheckBox);

   objRow.Cells.Add( tcCheckCell);
}

How can i add the objrow to gridview? Or is there any other method of adding a checkbox column to an ASP.net GridView ?

Answer 1

The problem is that you cannot add a CheckBox field to a GridView in order to have a column of checkboxes - the GridView doesn't support it:

Instead you have to change the template of each row, manually adding a CheckBox control to the template of a row.

• i can't tell you how to do that
• i can't tell you how to read which items the user has checked
• i can't tell you how to default some of them to checked

But it's what you have to do.
