    I changed the example DragAndDrop (first look) a little and have everything working great, but I want to be able to update the ContentControl.ContentTemplate(DataTemplate).

    I re-dedinfed the DataTemplate (below) and I'm trying to get a reference to TextBlock defined in the the DataTemplate during the execution of OnDragQuery so I can set the .Text of the TextBlock.

    DataTemplate defined (which has a TextBlock):
    <DataTemplate x:Key="ApplicationDragTemplate">
                    <Border BorderBrush="DarkGray" BorderThickness="1" Width="40" Height="40">
                            <Rectangle Width="38" Height="38" Canvas.Left="0" Canvas.Top="0" Stroke="DarkGray" Margin="0, 0, 0, 0" HorizontalAlignment="Center" VerticalAlignment="Center" UseLayoutRounding="False" RadiusY="0" RadiusX="0">
                                    <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
                                        <GradientStop Color="#FFFFFFFF" Offset="0"/>
                                        <GradientStop Color="#00000000" Offset="1"/>
                            <TextBlock Text="401" FontWeight="Bold" Foreground="DarkGray" Width="35" Canvas.Left="3" Canvas.Top="2" />

    Hello Voss Grose,

    My advice here is to bind the Text property of the TextBlock in the DataTemplate, something like:

    Text="{Binding MyProperty}"

    Then you will have to assign as Content of the ContentControl an object that has a property named MyProperty and afterwards you only need to change this object. If you want to change just this string, you can assign a string as the content:

    dragCue.Content = "402"

    and then use the empty binding in the template:


    Hopefully this will work for you,

    All the best,
