GridViewComboBoxColumn - showing an initial value

[Jason]

The documentation states:

> If you want to set initial values, you should match the GridViewComboBoxColumn to a column which has appropriate values in it. To do this, you should set the FieldName of the GridViewComboBoxColumn to be the same as the name of the existing column.

Can I see a code sample of how this is done?

I have a text column that I am able to successfully bind to show the values, but I'm not able to replace that text column with a ComboBoxColumn and still have it set the initial values like the text column does. Here's a code sample of what I've tried:

uxgrdBindingsGrid.MasterTemplate.Columns.Clear();
uxgrdBindingsGrid.AutoGenerateColumns = false;
uxgrdBindingsGrid.DataSource = bindings.ToList<SymbolBinding>();

 // this textbox column displays fine
GridViewTextBoxColumn dataSourceTextColumn = new GridViewTextBoxColumn();
dataSourceTextColumn.Name = "dataSourceTextColumn";
dataSourceTextColumn.HeaderText = "Data Source";
dataSourceTextColumn.FieldName = "DataSourceProperty";
dataSourceTextColumn.TextAlignment = ContentAlignment.MiddleLeft;
dataSourceTextColumn.Width = 150;
dataSourceTextColumn.IsVisible = true;
uxgrdBindingsGrid.MasterTemplate.Columns.Add(dataSourceTextColumn);

// this combobox column displays the drop down list if double-clicked, but does not display any values initially
GridViewComboBoxColumn dataSourceComboColumn = new GridViewComboBoxColumn("DataSourceProperty");
dataSourceComboColumn.Name = "dataSourceComboColumn";
dataSourceComboColumn.HeaderText = "Data Source";
dataSourceComboColumn.DataSource = this.dataSources;
dataSourceComboColumn.DropDownStyle = RadDropDownStyle.DropDownList;
dataSourceComboColumn.ValueMember = "ID";
dataSourceComboColumn.DisplayMember = "Path";
dataSourceComboColumn.FieldName = "DataSourceProperty";
dataSourceComboColumn.TextAlignment = ContentAlignment.MiddleLeft;
dataSourceComboColumn.Width = 150;
uxgrdBindingsGrid.MasterTemplate.Columns.Add(dataSourceComboColumn);
