var item = ((CheckBox)sender).Parent as RepeaterItem;
CheckBox chkAll = item.FindControl("CheckAll") as CheckBox;
Repeater rpt = (Repeater)(sender as Control).Parent.Parent.Parent.Parent;
RepeaterItem rptitme =(RepeaterItem) rpt.FindControl("CheckSelect");

Hey there,

In the header checkbox's checkedChanged event, you need to loop through all the Repeater items, find the CheckBox using FindControl and set its checked value same as the header checkbox. e.g,

C#

CheckBox chkheader = (CheckBox) sender;
           foreach (RepeaterItem item in Repeater1.Items)
           {
               CheckBox chkItem = (CheckBox) item.FindControl("YourCheckBoxID");
               if (chkItem != null)
               {
                   chkItem.Checked = chkheader.Checked;
               }
           }

Hope it helps.

Azee...

for (int i = 0; i < rptCC.Items.Count; i++)
{
CheckBox chk = (CheckBox)rptCC.Items[i].FindControl("CheckSelect");
if (chkAll.Checked)
{
chk.Checked = true;
}
}
