How to Find a Control in the footer of a repeater

I need to access a button control that is located in the footer of a repeater.  Currently I've tried this, which returned an "Object not set to..." error.

Sub someSub()
  CType(myRepeater.FindControl("myButton"), Button).Text = "New Text"
End Sub

Is this actually possible to do from outside the RepeaterItemEventArgs sub?

You cannot get the footer item as such outside the reapeteritemeventargs since the header, footer, and separator are not included in the item collection.

So you have to declare a repeateritem variable, assign the footer item to this variable (in itemdatabound) and then use it.

e.g: in C#.

RepeaterItem rpItem;

private void rpItem_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
   if (e.Item.ItemType == ListItemType.Footer)
          rpItem = e.Item;
}

Sub someSub()
  CType(rpItem.FindControl("myButton"), Button).Text = "New Text"
End Sub

There is a way, using a recursive function, to use FindControl to find a control by ID anywhere in the hierarchy.

If you save the UniqueID of the button, say in the viewstate, when the page posts back, you can use Page.FindControl("Controls_Unique_ID") to get a direct reference to it.
