A first chance exception of type ''System.NullReferenceException'' occurred in syncfusion.grid.dll Source code for EssentialGrid indicates: /// [Syncfusion.Documentation.DocumentationExclude()] public int GetItemCount() { return this.DataManager.List.Count; }

I did a search for GetItemCount in both our forum database and in our Direct Trac database to see if anyone else has reported an error involving this method. The only hit I found was this forum thread. http://www.syncfusion.com/Support/Forums/message.aspx?MessageID=24096 If that does not help, can you tell us how to see the problem in one of our samples, or can you upload a sample showing this problem?

Clay, Thanks. With a little tweaking I was able to figure it out.
