I have built a simple user control that contains 2 buttons, a text box and a
dropdownlist. When a button is clicked it sets the visible property
of the textbox/dropdownlist and the button. ie the buttons allow me to
toggle between the textbox and the dropdownlist. This works fine when the
control
is placed on the page but when it is placed inside a datalist, ie the
itemtemplate, the onclick events for the buttons fire but the visibility is
not set.
How do I change the visibility of the child controls of a user control when
it is placed inside a datalist?
I have placed some code below in the hope that it helps.Thanks in
advance.******* ********this is my user control******** *************** *
