Has anyone experienced this before? In my datagrid I''ve got one drop down that filters another drop down. When I press a character when my second drop down has focus I receive the following exception. Just curious if this looks fimiliar. This worked fine before upgrading to, but I have made other change on this form, but I don''t think relating to the drop downs though. I''ve put break points in all datagrid events, but I can''t find where it''s failing. Thanks, Todd ex.Message = Specified argument was out of the range of valid values.\r\nParameter name: ''140'' is not a valid value for ''index''. ex.StackTrace = " at System.Windows.Forms.ObjectCollection.get_Item(Int32 index)\r\n at Syncfusion.Windows.Forms.Grid.GridComboBoxCellRenderer.SynchronizeDisplayText(Int32 index)\r\n at Syncfusion.Windows.Forms.Grid.GridComboBoxCellRenderer.OnKeyPress(KeyPressEventArgs e)\r\n at Syncfusion.Windows.Forms.Grid.GridCellRendererBase.ProcessKeyEventArgs(Message& m)\r\n at Syncfusion.Windows.Forms.Grid.GridCellRendererBase.RaiseProcessKeyEventArgs(Message& m)\r\n

Are you using the technique in the article? http://www.syncfusion.com/Support/article.aspx?id=567 It makes sure the slave column''s GridBoundColumn.StyleInfo.DataSource/ValueMember/DisplayMember was set so the DataSource contains all possible entries for any potential value in the column. This is necessary if you are setting DropDownStyle = GridDropDownStyle.Exclusive.

Yes, I''m changing the datasource within the slave just like in this article. The only thing that is different is that I''m using the editor to create my GridBoundColumns. If I set DropDownStyle = GridDropDownStyle.Exclusive then I do not have an error, but the requirement is for this to be editable. (editable in production) BTW, I''m running version and not like a originally said if it matters. This is a rather large problem that is now in production, so any help is greatly appreciated. Thanks,

I need more help so I have created a direct-trac issue. Therefore, no need to reply to this post. Thanks,
