Capturing name of StackPanel from Drop event - wpf

Question

Within WPF I have the following XAML code:
<Page x:Class="com.MyCo.MyProj.Pages.Configuration.ManageLinkage.MasterLinkage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:local="clr-namespace:com.MyCo.MyProj.Pages.Configuration.ManageLinkage"
mc:Ignorable="d"
d:DesignHeight="450" d:DesignWidth="800"
Title="MasterLinkage">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="120"></ColumnDefinition>
<ColumnDefinition></ColumnDefinition>
</Grid.ColumnDefinitions>
<TabControl TabStripPlacement="Top" Background="Transparent">
<TabItem Header="Import">
<ListBox Margin="0,5,0,0" Name="lbxImportItems" HorizontalAlignment="Left" VerticalAlignment="Top" Width="110" Background="Transparent"
PreviewMouseLeftButtonDown="lbxImportItems_PreviewMouseLeftButtonDown" >
<StackPanel Orientation="Vertical" HorizontalAlignment="Center" Name="DBImport">
<Image Source="/Images/DBImport25px.png" VerticalAlignment="Center" HorizontalAlignment="Center"></Image>
<TextBlock Text="Database" Foreground="AntiqueWhite"/>
</StackPanel>
<StackPanel Orientation="Vertical" Name="CSVImport">
<Image Source="/Images/CSVImport25px.png" VerticalAlignment="Center" HorizontalAlignment="Center"></Image>
<TextBlock Text="CSV Import" Foreground="AntiqueWhite"/>
</StackPanel>
</ListBox>
</TabItem>
</TabControl>
<Canvas x:Name="cnvsLinkScreen" AllowDrop="True" Grid.Column="1" Background="Transparent" Drop="cnvsLinkScreen_Drop" DragOver="cnvsLinkScreen_DragOver" ></Canvas>
</Grid>
The code for capturing the event is here:
private void cnvsLinkScreen_Drop(object sender, DragEventArgs e)
{
Canvas parent = (Canvas)sender;
object data = e.Data.GetData(typeof(string));
StackPanel objIn = (StackPanel)e.Data;
...
}
The drag and drop work great, the event method created the image in the canvas. However, I want to capture the Name="" from the StackPanels which are dropped.
I found the Name buried super deep in the "DragEventArgs e" object. I was think that there should be a way to cast the object (or the object within that object) as a StackPanel to easily work with it. The above code does not convert the StackPanel object( it's not at the root or the child object; I tried both) so it exceptions on "StackPanel objIn = (StackPanel)e.data;"
How do I either translate the incoming object to a StackPanel or how do I access the Name attribute from the Stackpanel?

Answer 1

I got it. I was close with the translation. To translate / typecast the object to what you are working with I needed to use the following line:
StackPanel objIn = (StackPanel)(e.Data.GetData(typeof(StackPanel)));
Which is slightly different than above.
