I get the above error when trying to export my grid to excel.
Here is the code.
            GroupingGridExcelConverterControl converter = new GroupingGridExcelConverterControl();
            SaveFileDialog saveFileDialog = new SaveFileDialog();
            saveFileDialog.Filter = "Files(*.xls)|*.xls";
            saveFileDialog.DefaultExt = ".xls";
            if (saveFileDialog.ShowDialog() == DialogResult.OK)
                converter.ExportStyle = false;
                saveFileDialog.FileName, Syncfusion.GridExcelConverter.ConverterOptions.Visible);
However when this code runs error happens
Cannot bind to the new display member. Parameter name: newDisplayMember
I use comboboxes in my application. Here is the sample code
comboBoxLists.DisplayMember = "Name";
comboBoxLists.ValueMember = "Name";
That is I assign both display and value to the same property. Could that be why I am getting this error?

I thought I would branch out in this question.
Currently the above described process takes a very long time and when I try to use either thread.Start(), background worker or use CurrencyManager.SuspendBinding() to somehow put the export work behind the scenes I get the following exception “BindingSource cannot be its own data source”.
I am new to threading :S so your help would be much appreciated. Thank you
