check all checkboxes in radgrid on button click.

Hi,

check all checkboxes in radgrid on button click.  button is placed outside radgrid. I tried thos method on button click.

                CheckBox chb;
                for (int i = 0; i < RadGrid1.Items.Count; i++)
                {
                    chb = (CheckBox)RadGrid1.Items[i].FindControl("chkSelectItem");
                    chb.Checked = true;
                }
This will fix the check boxes in the radgrid on that page. if I move to another page(pagination), it will be unchecked in there.
Thanks in advance.

I am able to check all the button. But When I tried to retrieve all the checked boxes, checked, I am able to get the checkboxes ticked only in the first page.
other page value are not getting retrieved using the code:

 for (int i = 0; i < rdNew.Items.Count; i++)
            {
                CheckBox chkSelected = (CheckBox)rdNew.Items[i].FindControl("chkS");
                String Id = rdNew.Items[i]["id"].Text;
               
                if (chkSelected.Checked && chkSelected != null)
                {
                    if (list.Count == 0)
                    {
                        list.Add(Id);
                    }
                }
            }
I am not getting the total list, of the users checked.

Hi,

When paging is enabled in the grid, a solution would be to temporarily disable paging, loop through all the items in the grid, select the items and then enable paging back.

Give this suggestion a try and see if it works for you..
