I have three “user controls” and on page (see below). The steps that I am trying to do and will not give up on till I get a solution. Everything is possible; just trying to rig it to work is the test.
Walk through: The “Default.aspx” page loads and within that page there are two “PlaceHolder”s. Both are pre-populated with a link (PlaceHolder01) and text (PlaceHolder02). When the link within “PlaceHolder01” (Link One) is clicked; on the postback “PlaceHolder01” gets a new user control injected within it and the verbage for “PlaceHolder01” is now “Link Two”. All this works so far.
Here is where the problem starts:
When you click on “Link Two” within “PlaceHolder01” the postback should change the value within “PlaceHolder02” with another user control. But it does not.
Anyone knows why? Or has a work around?
Thanks,
