Crash in TreeviewAdv when displaying tooltip

[Justin Koh]

We are getting a crash in a docked treeview when it tries to display a tool tip. Here is the stack trace: It is hard to reproduce this error, however. Has anyone seen anything similar?

We are using v 2.0.5.1 . Upgrading at this time is not an option, but we''d still like to know if there is a fix for this in a later version.

Nonrecoverable error: Cannot access a disposed object named "TreeViewAdv".
Object name: "TreeViewAdv".

Hi Justin, We have made several related fixes in the TreeViewAdv control and the docking windows framework since the release of v2.0.5.1, and I am afraid we will not be able to support those fixes in v2.0.5.1 itself. The v3.0 Release Candidate has these fixes, and you could test your application in this version to see if this issue has been taken care of. The v3.0 Release Candidate is available for download, and you could so so from the link below : Essential Suite 3.0 Release Candidate available for download You could then upgrade to v3.0 final release when it becomes available (we plan to bring out v3.0 final release shortly). We appreciate your cooperation on this issue. Regards, Guru Patwal Syncfusion, Inc.
