Simple drop down editor?

[Karl B]

How can I make this work with the property grid?  I am using a property grid with automatically generated properties and on edit I want SelectedIndex1 and SelectedIndex2 to display a list of my available indexes for the user to choose from.

public class MyIndexSelector
{
    private readonly List<int> m_someList = new List<int> () {1, 2, 3};
    [Browsable (false)]
    public List<int> AvailableIndexes { get { return m_someList; } }

    //??[Telerik.Windows.Controls.Data.PropertyGrid.Editor (typeof (IndexEditorControl), Telerik.Windows.Controls.Data.PropertyGrid.EditorStyle.DropDown)]
    public int SelectedIndex1 { get; set; }

    //??[Telerik.Windows.Controls.Data.PropertyGrid.Editor (typeof (IndexEditorControl), Telerik.Windows.Controls.Data.PropertyGrid.EditorStyle.DropDown)]
    public int SelectedIndex2 { get; set; }
}

Hello Karl,

The suggested approach in this scenario would be to create a custom DataTemplate and set that as the EditorTemplate for the PropertyDefinitions of interest in RadPropertyGrid's AutoGeneratingPropertyDefinition event:

private void RadPropertyGrid_AutoGeneratingPropertyDefinition(object sender, Telerik.Windows.Controls.Data.PropertyGrid.AutoGeneratingPropertyDefinitionEventArgs e)
{
    if (e.PropertyDefinition.SourceProperty.Name == "Country")
    {
        e.PropertyDefinition.EditorTemplate = (DataTemplate)Application.Current.Resources["ComboBoxTemplate"];
    }
}

<Application.Resources>
    <DataTemplate x:Key="ComboBoxTemplate">
        <telerik:RadComboBox ItemsSource="{Binding Countries}" SelectedValue="{Binding Country}" />
    </DataTemplate>
</Application.Resources>

I'm attaching a sample project to better demonstrate this. Please have a look at it and let me know whether such an approach would work for you.
