ResetState or DeleteDockState

[Helmut Wahrmann]

Hi,

i have a question on how to restore the original layout of a DockingManager.

I have set PersistState="True".

When now the various elements have been moved around and i want to restore the original layout of the program, how can i do that?

I have a button in my app, which executes a ResetState and a DeleteDockState, but the Layout stays the same.

Now when exiting the App, the layout is saved again, because of PeristState.

How could i achieve, what i want?

thanks,

Helmut

Ok, i found now a way doing my own handling of saving and loading the state from an external file.

The only thing, which is not nice, is that i need code behind in my MVVM application to load the and save the states, since i need to reference the Dockingmanager by the name.

I haven't found how to handle this via Bindings.

Hi Helmut, 

 

Thanks for your patience. 

 

We have checked your query "Perform Save and LoadDockState serialization in DockingManager using MVVM" and we can meet your requirement in MVVM pattern by using DockingManager interaction behaviors. The dock states can be saved and loaded by pressing Ctlr+S and Ctrl+L, respectively, using interaction behaviors only. Please find the code snippet, sample for the same.   

 

Code Snippet: 

 

View: 

 

<syncfusion:DockingManager x:Name="SyncDockingManager" Grid.Row="1" > 

            <interaction:Interaction.Behaviors> 

                <local:ViewModel/> 

            </interaction:Interaction.Behaviors> 

             

            <ContentControl x:Name="SolutionExplorer" syncfusion:DockingManager.Header="Solution Explorer" /> 

            <ContentControl x:Name="ToolBox" syncfusion:DockingManager.Header="Toolbox" /> 

            <ContentControl x:Name="Properties" syncfusion:DockingManager.Header="Properties" /> 

            <ContentControl x:Name="Output" syncfusion:DockingManager.Header="Output"/> 

            <ContentControl x:Name="StartPage" syncfusion:DockingManager.Header="Start Page" /> 

        </syncfusion:DockingManager> 

 

ViewModel: 

 

public class ViewModel : Behavior<UIElement> 

    { 

        protected override void OnAttached() 

        { 

            Window parent = Application.Current.MainWindow; 

            AssociatedObject.PreviewKeyDown += (sender, e) => 

            { 

                if (e.Key == Key.S && (Keyboard.IsKeyDown(Key.LeftCtrl) || Keyboard.IsKeyDown(Key.RightCtrl))) 

                { 

                    (AssociatedObject as DockingManager).SaveDockState(); 

                } 

                if (e.Key == Key.L && (Keyboard.IsKeyDown(Key.LeftCtrl) || Keyboard.IsKeyDown(Key.RightCtrl))) 

                { 

                    (AssociatedObject as DockingManager).LoadDockState(); 

                } 

            }; 

        } 

    }
