Hi Yogi, I assume you are using mutliple thread. If so please check this KB article. http://www.syncfusion.com/Support/article.aspx?id=572 Any calls into the grid must be done on the thread that creates it, and you can use grid.InvokeRequired to check for this. On looking at our Direct-Trac history many customers have reported it due to threading problems. Sometimes threading causes unexpected behaviors. Can you please make sure that it is on the same thread? Here is a sample. Let me know if this helps. Best regards, Haneef

Haneef, Tks for the reply. We are very much knowledgable about UI multi-threading issues, so the below call is made on the GUI Thread. We haven''t faced such issues in Syncfusion 3.0, its a straight forward porting to 4.1 with no change in our code. Unfortunately this error pops up intermittently so there is no way that we can easily reproduce this problem. Please advise.. >Hi Yogi, > >I assume you are using mutliple thread.

Hi Yogi,

Setting the UseListChangedEvent property to true will avoid the mentioned issue.

this.gridDataBoundGrid1.UseListChangedEvent = true;

Let me know if you need any further assistance.

It is set to true and we still get that error. Please find the attached grid code we use. Please note it is a Hierarchial Grid Databound. >Hi Yogi, > >Setting the UseListChangedEvent property to true will avoid the mentioned issue. > >this.gridDataBoundGrid1.UseListChangedEvent = true; > >Let me know if you need any further assistance. > >Best Regards, >Haneef
