Dear Infragistics experts,
I have a WebExplorerBar on my MasterPage with most of it's items set via markup. But I programmatically add a few items to a certain ExplorerBarItem in code. This is done in the Load event of the MasterPage.
When you navigate from page to page there's not a problem. But one page has a button. When this button is clicked a postback is happening (ofcourse) and this is when the problem occurs.
Apparantly the WebExplorerBar is using ViewState, but it lost information on the items which were added in code. This 'causes an 'object or reference not set' error.
What am I doing wrong?
Update:
I've even put everything on 1 single Page in a brand new test solution. A WebExplorerBar (with some items via markup), a ScriptManager and a Button. In the load event I add 2 items when it's not a postback. When I run the solution it works fine. When the button is clicked I get an error. I'm starting to think it's not my fault, to be honest.
Would someone from Infragistics care to take a look at this?
