WPF Binding using a property as value to define a Binding - wpf

Question

I have to say I am not getting used to WPF.
I have the problem that I have a Property that contains the value, but I want not to bind to that property.
I want to bind the property to a property named as the value in the property Name.
This is my xaml:
<telerik:RadMultiColumnComboBox x:Name="radMultiColumnComboBox_Part"
Grid.ColumnSpan="3" Grid.Row="1"
SelectedItem="{Binding SelectedItem, ElementName=selector, Mode=TwoWay}"
>
<telerik:RadMultiColumnComboBox.ItemsSourceProvider>
<telerik:GridViewItemsSourceProvider ItemsSource="{Binding ItemsSource, ElementName=selector}"
AutoGenerateColumns="False"
>
<telerik:GridViewItemsSourceProvider.Columns>
<!-- This line below is what I am talking about -->
<telerik:GridViewDataColumn DataMemberBinding="{Binding Name, ElementName=selector}" />
</telerik:GridViewItemsSourceProvider.Columns>
</telerik:GridViewItemsSourceProvider>
</telerik:RadMultiColumnComboBox.ItemsSourceProvider>
</telerik:RadMultiColumnComboBox>
I think mostly a try can explain it best:
public override void OnApplyTemplate()
{
base.OnApplyTemplate();
var sourceProvider = radMultiColumnComboBox_Part.ItemsSourceProvider as GridViewItemsSourceProvider;
var columns = sourceProvider.Columns;
foreach(var gridViewColumn in sourceProvider.Columns)
{
var binding = new Binding(DisplayMemberPath);
binding.Source = gridViewColumn.DataContext;
// there is no property DataMemberBinding.
BindingOperations.SetBinding(gridViewColumn, Telerik.Windows.Controls.GridViewColumn.DataContextProperty, binding);
}
}
I would prefer a solution in xaml but in c# would also be fine.
Thank you.

Answer 1

This is not possible to do in pure XAML. You'll need to create the binding programmatically. Something like this:
var gridViewColumn = sourceProvider.Columns[0] as GridViewDataColumn;
string propertyToBindTo = selector.Name;
gridViewColumn.DataMemberBinding = new Binding(propertyToBindTo);

Answer 2

The solution:
var provider = this.GridViewItemsSourceProvider;
// var provider = this.radMultiColumnComboBox_Part.ItemsSourceProvider as GridViewItemsSourceProvider;
provider.Columns.Add(new GridViewDataColumn() { DataMemberBinding = new Binding("Name") });
