WorkspaceManager.LoadWorkspace(String, Object) Method

Loads a workspace from the target local file and places it in the WorkspaceManager.Workspaces collection under the specific name.

Namespace: DevExpress.Utils

Assembly: DevExpress.Utils.v24.1.dll

NuGet Packages: DevExpress.Utils, DevExpress.Wpf.Core

Declaration

C#

public bool LoadWorkspace(
    string name,
    object path
)

VB.NET

Public Function LoadWorkspace(
    name As String,
    path As Object
) As Boolean

Parameters

Name	Type	Description
name	String	A String value that is the name under which the loaded workspace is kept in the WorkspaceManager.Workspaces collection.
path	Object	An Object that is the location of the file that stores a workspace.

Returns

Type	Description
Boolean	true if the workspace was successfully loaded; otherwise, false.

Remarks

The LoadWorkspace method loads a workspace from a file and makes it available from the WorkspaceManager.Workspaces collection. However, this workspace remains inactive. To activate this workspace, use the WorkspaceManager.ApplyWorkspace method afterwards.

Example

The following code shows how to use the WorkspaceManager component to save the form’s bounds and state, and the layout of DevExpress controls when a form is closed, and load this layout when the form starts.

You may need to call the controls’ ForceInitialize methods (e.g., GridControl.ForceInitialize) before applying layouts to the controls in a Form.Load event handler.

C#

 string file = "layout.xml";
 string workspaceName1 = "MyLayout";

 private void Form1_Load(object sender, EventArgs e) {
     //Use the WorkspaceManager to handle the layout of DevExpress controls that reside within the current form.
     workspaceManager1.TargetControl = this;

     // Save & restore the form's size, position and state along with DevExpress controls' layouts.
     workspaceManager1.SaveTargetControlSettings = true;

     // Disable layout load animation effects 
     workspaceManager1.AllowTransitionAnimation = DevExpress.Utils.DefaultBoolean.False;

    // Disable (de)serialization for the following controls (if required):
    //WorkspaceManager.SetSerializationEnabled(gaugeControl1, false);
    //WorkspaceManager.SetSerializationEnabled(accordionControl1, false);

    // When restoring layouts of controls in a Form.Load event handler,
    // you may need to call the controls' ForceInitialize methods to finish their initialization before restoring their layouts.
    //gridControl1.ForceInitialize();
    //dockManager1.ForceInitialize();
    //barManager1.ForceInitialize();
    //...

     //Load DevExpress controls' layouts from a file
     if (workspaceManager1.LoadWorkspace(workspaceName1, file, true))
         workspaceManager1.ApplyWorkspace(workspaceName1);
 }

 private void Form1_FormClosed(object sender, FormClosedEventArgs e) {
     //Save DevExpress controls' layouts to a file
     workspaceManager1.CaptureWorkspace(workspaceName1, true);
     workspaceManager1.SaveWorkspace(workspaceName1, file, true);
 }

VB.NET

Dim file As String = "layout.xml"
Dim workspaceName1 As String = "MyLayout"

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    ' Use the WorkspaceManager to handle the layout of DevExpress controls that reside within the current form.
    WorkspaceManager1.TargetControl = Me

    ' Save & restore the form's size, position and state along with DevExpress controls' layouts.
    WorkspaceManager1.SaveTargetControlSettings = True

    ' Disable layout load animation effects 
    WorkspaceManager1.AllowTransitionAnimation = DevExpress.Utils.DefaultBoolean.False

    ' Disable (de)serialization for the following controls (if required):
    'WorkspaceManager.SetSerializationEnabled(GaugeControl1, False)
    'WorkspaceManager.SetSerializationEnabled(AccordionControl1, False)

    ' When restoring layouts of controls in a Form.Load event handler,
    ' you may need to call the controls' ForceInitialize methods to finish their initialization before restoring their layouts.
    'GridControl1.ForceInitialize()
    'DockManager1.ForceInitialize()
    'BarManager1.ForceInitialize()
    '...

    ' Load DevExpress controls' layouts from a file
    If WorkspaceManager1.LoadWorkspace(workspaceName1, file, True) Then
        WorkspaceManager1.ApplyWorkspace(workspaceName1)
    End If
End Sub

Private Sub Form1_FormClosed(sender As Object, e As FormClosedEventArgs) Handles MyBase.FormClosed
    ' Save DevExpress controls' layouts to a file
    WorkspaceManager1.CaptureWorkspace(workspaceName1, True)
    WorkspaceManager1.SaveWorkspace(workspaceName1, file, True)
End Sub
