GroupingGridToExcel Cannot bind to the new display member. Parameter name: newDisplayMember

[Gaukhar Massabayeva]

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;
                converter.GroupingGridToExcel(this,
                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
