如何将XAML（ControlTemplate）转换为Code-Behind

Question

<dxg:LookUpEdit Margin="5" HorizontalAlignment="Stretch" VerticalAlignment="Center" 
                    ItemsSource="{Binding}"
                    DisplayMember="Name" 
                    AutoPopulateColumns="False">
    <dxg:LookUpEdit.PopupContentTemplate>
        <ControlTemplate>
            <dxg:GridControl Name="PART_GridControl">
                <dxg:GridControl.Columns>
                    <dxg:GridColumn FieldName="Name"/>
                    <dxg:GridColumn FieldName="Date"/>
                </dxg:GridControl.Columns>
            </dxg:GridControl>
        </ControlTemplate>
    </dxg:LookUpEdit.PopupContentTemplate>
</dxg:LookUpEdit>

please help me, I do not know how to add GridColumn on GridControl and set LookUpEdit.PopupContentTemplate = GridControl

Thank you very much. I think XAMLREADER can help me, I'm stuck here

ControlTemplate ct = new ControlTemplate();
FrameworkElementFactory gridcontrol = new FrameworkElementFactory(typeof(GridControl));
FrameworkElementFactory gridcolumn = new FrameworkElementFactory(typeof(GridColumn));
gridcontrol.SetValue(?, ?);
gridcolumn.SetValue(?, ?);
ct.VisualTree = gridcontrol;

creating control/data templates in code behind involves factory classes, that may be more complicated for non framework types.

example from Creating a control template with code behind

ControlTemplate template = new ControlTemplate(typeof(ListBoxItem));
FrameworkElementFactory elemFactory = new FrameworkElementFactory(typeof(Border));
elemFactory.Name = "Border";
elemFactory.SetValue(Border.CornerRadiusProperty, new CornerRadius(5));
elemFactory.SetValue(Border.PaddingProperty, new Thickness(1));
elemFactory.SetValue(Border.SnapsToDevicePixelsProperty, true);
template.VisualTree = elemFactory;

//same can be used as 
LookUpEdit.PopupContentTemplate = template;

above is just an example, you may need to use the appropriate types

alternatively keeping the control templates in resource dictionary may help you

or the easiest solution is to parse the xaml in code behind

const string xaml = "<ControlTemplate><dxg:GridControl Name=""PART_GridControl""><dxg:GridControl.Columns><dxg:GridColumn FieldName=""Name""/><dxg:GridColumn FieldName=""Date""/></dxg:GridControl.Columns></dxg:GridControl></ControlTemplate>";
ControlTemplate template = XamlReader.Parse(xaml) as ControlTemplate;

//this can be used as 
LookUpEdit.PopupContentTemplate = template;
