retrieve all checkbox ticked rows from radgrid

[digish devassy]

I am able to check all the checkboxes. 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("chkSelected");
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.

Hello,

I cannot reproduce the issue at my end. Check the following help documentation.
Persisting CheckBox control state in GridTemplateColumn on rebind.

HI shinu,

I respect your replies,

I am in a hurry. All my requirement is, how to loop through all the checked checkboxes in radgrid and get the id associated with the checkboxed rows. I am not finding a solution. my client has bought your stuff. It is painful to see that, I get such non serious replies from telerik forum
thanks,

Hi,

i hope it will help

//MakeAllowPaging false and collect all data
         radVenues.AllowPaging = false;

radVenues.Rebind();

List<int> CheckedItemlist = new List<int>();

            var Count=(from Item in radVenues.MasterTableView.Items.Cast<GridDataItem>()

                       where  ((CheckBox)Item.FindControl("chkLoop")).Checked=true

                       select AddItemIdinList(Item,CheckedItemlist)).Count();

//MakeAllowPaging True
   radVenues.AllowPaging = true;

   radVenues.Rebind();

 

 public bool AddItemIdinList(GridDataItem Item, List<int> Itemlist)

        {

            int id=0;

            int.TryParse(Item.GetDataKeyValue("ID").ToString(), out id);

            Itemlist.Add(id);

            return true;

        }
