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);
