We have been plagued with this red X issue for a while now. The scenario to replicate the problem would be to switch between the end tab and any of the other tabs in the control pictured below. It appears to only happen with this particular tab and you have to click very quickly and roughly about 10-15 times between the tabs before the X will appear. I can do it every-time without fail. A couple things to note: it appeared to be failing on the OnPaint() Method, we are using custom images in the cells, it only happens with the one specific tab (building elements). We are not sure what could be causing this and any insight would be extremely helpful. Any information needed please let me know and I will keep a close eye on this thread.
Hi,
Form the screenshot and the description I guess that you are talking about Windows Forms application? To understand what may be the cause we have to get more details about your application. About this tab that give you the error can you let us know what kind of controls you have there? If you debug it did you see any error? Did you use any custom controls that override the OnPaint methods and etc, did you use threading’s to load or build up that tab and the data in it?
I am looking forward to hearing form you.
Hi Dimi,
We are currently using an UltraTree inside a user control. There were a handful of times we were able to look at the stack trace and we did notice an OnPaint( ) method error. We did not use any custom controls that override the OnPaint method nor do we have any threads that load up the data on it.
Let us know if theres anything else we could do to help assist with solving this issue. We have yet to figure it out and would love to get this problem resolved. Thanks!
