C#:
foreach (RepeaterItem item in rpVoteList.Items)
{
if (item.ItemType == ListItemType.Item || item.ItemType == ListItemType.AlternatingItem)
{
var hf= (HiddenField)item.FindControl("HiddenField2")
}
}
Or
protected void rpVoteList_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
var value = (HiddenField) e.Item.FindControl("HiddenField2")).Value;
}
