Asked by: shenoyroopesh

Hi.
    Im trying to add one checkbox column to the DataGridView which already contains other 4 other columns. Im binding data for these 4 columns from a datasource. but i want this 5th column to be a checkbox column which i can use for the bulk operation on datagrid rows.

I have handled cell click event on this datagridview. I wanto know how do i check whether check boxes in the grid are selected or not selected (only two states).
Is there any other good way to handle bulk operations on the datagridview rows.

When you want to check the checkboxes to be checked or not. You can handle the bulk event in Item_Command event.

 

by: angus_young_acdcPosted on 2009-09-22 at 01:15:53ID: 25390521

The following code will do the check for you:
            int index = dataGridView1.Rows.Count - 1;
            foreach (DataGridViewRow row in dataGridView1.Rows)
            {
                if (row.Index < index) // You don't want to check the unbound row at the bottom
                {
                    if (row.Cells["Column1"].Value != null && (bool)row.Cells["Column1"].Value != false)
                    {
                        if ((bool)row.Cells["Column1"].Value == true)
                        {
                            MessageBox.Show("row " + row.Index + " is checked");
                        }
                    }
                }
            }

Was in a bit of a rush posting that, really you don't need the check to see if it's true as if it meets the conditions before that, then it will pass as true.  :)
