Hi - I'm new to this SDK and C#. I'm trying to code a dockpane which lists all rasters of a given folder. this works. now I would like to add the listed rasters with drag&drop (or right-click - add) to the current map. unfortunately I don't get it to work. it doesn't throw any errors, so I have no clue what's missing... can someone help me please?
here my xaml:
<ListView Name="FileListView" SelectionChanged="FileListView_SelectionChanged" AllowDrop="True" Drop="FileListView_Drop" Height="Auto" Margin="0,28,0,113" Grid.Row="1">
<ListView.View>
<GridView>
<GridViewColumn Header="Filename" Width="250">
<GridViewColumn.CellTemplate>
<DataTemplate>
<TextBlock Text="{Binding}" />
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
</GridView>
</ListView.View>
</ListView>
<Button Content="Refresh" Click="OnRefreshButtonClicked" HorizontalAlignment="Left" Margin="0,3,0,0" Grid.Row="1" VerticalAlignment="Top"/>
