Obtain the control in the Repeater control template Column

Directly Using repeater. findcontrol cannot obtain the sub-control, because the sub-control is actually in itemtemplate. Translate a comment:
If (roles. isuserinrole ("admin "))
{
Button Delete = (button) rptnotering. items [0]. findcontrol ("btndelete ");
Delete. Visible = true;
Button edit = (button) rptnotering. items [0]. findcontrol ("btnedit ");
Edit. Visible = true;
}

Inside a repeater are 0-Snapshot items... items [x] is where X is the index of the specific itemtemplate instance.
If your repeater returns 10 rows of data, then your repeater returns an instance of itemtemplate 10 times
And places each instance in the items [] collection.

Your findcontrol method is not looking inside the itemtemplate.
Hope this helps

The general meaning is: There are 0 items in the repeater, and items [x] is the instance for creating the template column. If your repeater has 10 rows of data, your repeater will return 10 itemtemplate instances, each instance is aggregated in the item set.

So I did it in the event, and the effect is still acceptable, but this loop does not feel very good. Also, pay attention to the above operations after the repeater data is fixed, otherwise it will not work ....
