Does the TreeViewAdvDataBound control work well with the latest version (4.1.0.50) of the Essential Studio? The library provided at http://www.syncfusion.com/support/user/uploads/treeviewadvdatabound_lib.zip still references older Syncfusion assemblies. So is there also a new version of the TreeViewAdvDataBound control available? Any improvements, bug fixes? Kind regards Wolfgang

Deepa, I just experienced that the TreeViewDataBound is pretty buggie. Basically when I call the dataSet.tables["mytable"].clear() after the TreeViewDataBound control is deleted, it has null reference exception I guess table.clear() is trying call the events that was assoicated the deleted treeViewDataBound control. I think the TreeViewDataBound need to handle to clear all the DB_xxxEvent when the TreeViewDataBound control is delete (or disposed if you want this word). What do you think how sooon we have newer version of TreeViewDataBound. Thanks Here is the stack System.NullReferenceException was unhandled by user code Message="Object reference not set to an instance of an object."

Hi Ken, I apologize for the inconvenience caused. I was able to reproduce the issue and I have logged a bug report bug #1630 NullReferenceException occurs when dataSet.tables["mytable"].clear() is called in DataBound sample. Regarding this issue you could track the status of this bug fix in the above link.We will try our very best to implement this at the earliest. We will let you know for sure, regarding the newer version of TreeViewDataBound once it is been addresed. Thanks for your patience and interest in Syncfusion products. Best regards, Deepa.T.S
