GridDataControl ComboBox Data Binding

[Elisha John]

Hello

1. I created a griddatacontrol and data binded the itemsource and datacontext to an entityframeworkmodel like so:
private ExampleEntities context = new ExampleEntities();

this.ExampleGridDataControl.DataContext = this.context.Examples.ToList();



2. I then created a comboBox column like so:







3. And set the comboBox itemsSource:

StringCollection exampleList = new StringCollection();
exampleList.Add("Example1");
exampleList.Add("Example2");
exampleList.Add("Other");
this.ExampleGridDataControl.VisibleColumns[1].ColumnStyle.ItemsSource = exampleList;

4. When I load the gridDataControl, the comboBoxes cell values correspond to the actual values in the entityframework, however when I tried to change the values from the combo box, I get an error:
"Unable to cast object of type 'Syncfusion.Windows.Controls.Grid.HoverListBoxItem' to type 'System.String'.

Are there any specific ways I would need to dataBind the ComboBox column? It seems that there's an error converting the values back to the binding context. Please help.

Thank you
