I recently discovered a bug in Infragistics 9.2 (don't know if also in other versions) regarding the WinTree.
NodeStyle is set to CheckBox; when checking or unchecking the nodes using space key, if the number of nodes exceeds ~1500, the current node loses focus (goes unactive) and the focus is set on the first node (first node becomes the active node). This happens only when changing state via space key and when dealing with a big number of nodes.
Hope this helps someone, maybe Infra will find a fix in the next release.
Have a good one folks!
That seems pretty unlikely to be a bug in the tree. I can't imagine any code in the tree that would cause the control to lose focus.And I especially don't see why the number of nodes in the tree would make any difference.
Are you sure nothing in your code is doing this? Perhaps some code in an event of the tree?
Can you post a small sample project demonstrating this behavior?
I am very sure that the number of nodes creates the bug, because if I fill the tree with less than ~1500 elements, it works just fine.
I forgot to mention that the tree is in a popup control.
However, I do not have any events linked to the tree.
I cannot post the project right now, will do it in a couple of days.
