Hello,
I have a serious issue with the designer for the tree control..if I click on Nodes in the properties tab to create some nodes design time...after I click OK, even if I don't add anything..it removes the first node and all it's children. If I click nodes again, then ok without even doing anything (add removing nodes) it does the same thing.
The only reason I can think of for behavior like this is if you are using an inherited form with a tree on the base form. Is that the case? If so, then you cannot modify the nodes collection on the child form - the form designer simply can't handle it.
Sorry, should add that I am using VS 2010, with the the Infragistics 2010 Vol2
