How to add dock child in WPF DockingManager by drag and drop from other controls?
1 min read
WPF DockingManager has built in support to drag and drop Dock child from one DockingManager to another. You can also configure child dock controls by drag and drop from other controls.
For example, consider you need to add Document child by drag and drop of ListViewItem from ListView and it can be achieved by handling Drop event in DockingManager.
XAML
<syncfusion:DockingManager x:Name="clientdockingManager" IsVS2010DraggingEnabled="True"
Drop="clientdockingManager_Drop" IsEnableHotTracking="True" EnableScrollableSidePanel="True" ContainerMode="TDI" PersistState="false" AllowDrop="True" UseDocumentContainer="True">
<ListView Margin="10,50,10,10" Name="lstView" BorderBrush="WhiteSmoke"
syncfusion:DockingManager.SideInDockedMode="Left"
syncfusion:DockingManager.State="Dock" AllowDrop="True"
syncfusion:DockingManager.DesiredWidthInDockedMode="350"
syncfusion:DockingManager.Header="ListView" PreviewMouseLeftButtonDown="lstView_PreviewMouseLeftButtonDown" MouseMove="lstView_MouseMove" DragEnter="lstView_DragEnter" Drop="lstView_Drop">
<ListView.View>
<GridView>
<GridViewColumn Header="Title" Width="80" DisplayMemberBinding="{Binding Title}" />
<GridViewColumn Header="Note" Width="150" DisplayMemberBinding="{Binding Note}" />
</GridView>
</ListView.View>
</ListView>
<!--Document Area-->
<Grid syncfusion:DockingManager.State="Document"
syncfusion:DockingManager.Header="Docking Manager" syncfusion:DockingManager.DesiredWidthInFloatingMode="150" >
<FlowDocumentScrollViewer VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Auto">
<FlowDocument>
<Paragraph FontSize="14" FontFamily="Segoe UI" >
This sample illustrates the Linked Manager support in Docking Manager.
The windows belonging to one docking Manager can be dragged and dropped to other Docking Manager.
</Paragraph>
</FlowDocument>
</FlowDocumentScrollViewer>
<!--Remaining Client Area-->
</Grid>
</syncfusion:DockingManager>
C#
/// <summary>
/// Invoked when Drop some control on the DockingManager
/// </summary>
private void clientdockingManager_Drop(object sender, DragEventArgs e)
{
ContentControl CC = new ContentControl();
if (item != null)
{
CC.Content = new TextBlock() { Text = item.Note };
DockingManager.SetState(CC, DockState.Document);
DockingManager.SetHeader(CC, item.Title);
this.clientdockingManager.Children.Add(CC);
}
isdragenter = false;
}
