GridDataBoundGrid : Exception

[Administrator]

Customer Query :
In our application, we are using GridDataBoundGrid control (Syncfusion version - 3.3, .Net framework - 1.1). When I try to load the datagrid with datatable, sometimes it is throwing the following exceptions.

System.ArgumentException: Value does not fall within the expected range.

Could you please let us know the cause of this exception and how to avoid this.

Hi Vanitha,

The error which you have mentioned, is an indication of threading issues.

Are there multiple threads involved in your appilcation? If so, please check the Knowledge Base(KB) article link below.

http://www.syncfusion.com/support/kb/grid/Default.aspx?ToDo=view&questId=78

Intermittant errors can be indications of threading issues. Any calls into the grid must be done on the thread that creates it, and you can use grid.InvokeRequired to check for this.
