Using a layout file to preserve user changes [Janus ButtonBar Control v3.5 for .NET] How to save and load a layout file to preserve ButtonBar control settings. Using a layout file you could be able to preserve even the changes to the layout made by the user.

The steps followed to create this project are:

1) Create a new Visual Basic or C# project using "Windows Application" Template.

2) Add a ButtonBar control to Form1.

3) Add a button and change its Text property to "Load".

4) In the Click event of the load button, load the layout from a file calling a procedure similar to
the following:

In VB:


   Private Sub LoadLayout()
       Dim LayoutDir As String = GetLayoutDirectory() + "\ButtonBarLayout.bbl"
       Dim LayoutStream As FileStream
       LayoutStream = New FileStream(LayoutDir, FileMode.Open)
       ButtonBar1.LoadLayoutFile(LayoutStream)
       LayoutStream.Close()
   End Sub

In C#:


   private void LoadLayout()
   {
       string layoutDir = GetLayoutDirectory() + @"\ButtonBarLayout.bbl";
       FileStream layoutStream;
       layoutStream = new FileStream(layoutDir, FileMode.Open);
       buttonBar1.LoadLayoutFile(layoutStream);
       layoutStream.Close();
   }

5) Add a button and change its Text property to "Save"

6) In the Click event of the save button, save the layout from to file calling a procedure similar to
the following:

In VB:


   Private Sub SaveLayout()
       Dim LayoutDir As String = GetLayoutDirectory() + "\ButtonBarLayout.bbl"
       Dim LayoutStream As FileStream
       LayoutStream = New FileStream(LayoutDir, FileMode.Create)
       ButtonBar1.SaveLayoutFile(LayoutStream)
       LayoutStream.Close()
   End Sub

In C#:


   private void SaveLayout()
   {
       string layoutDir = GetLayoutDirectory() + @"\ButtonBarLayout.bbl";
       FileStream layoutStream;
       layoutStream = new FileStream(layoutDir, FileMode.Create);
       buttonBar1.SaveLayoutFile(layoutStream);
       layoutStream.Close();
   }

You can also save a layout by calling the Update method of the Layout.

In VB:


       If Not ButtonBar1.CurrentLayout Is Nothing Then
           ButtonBar1.CurrentLayout.Update()
       End If

In C#:


       if(buttonBar1.CurrentLayout!=null)
       {
           buttonBar1.CurrentLayout.Update();
       }

7) Run the project.

Using a ButtonBarGroup as Container Control [Janus ButtonBar Control v3.5 for .NET] Adding controls into a ButtonBarGroup.

The steps followed to create this project are:

1) Create a new Visual Basic or C# project using "Windows Application" Template.

2) Drag a ButtonBar control from the toolbox into the Form designer.

3) Right click in the ButtonBar control and select "Groups Designer" menu. In the Groups Designer dialog add a new group and set its Container property to true in the property window.

4) In the Load event of the form add the TreeView control as follows:

In C#


private void Form1_Load(object sender, System.EventArgs e)
{   
       this.buttonBar1.Groups[0].ContainerControl.Controls.Add(this.treeView1);
this.treeView1.Dock = DockStyle.Fill;
}

In VB


Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles _
MyBase.Load
       Me.ButtonBar1.Groups(0).ContainerControl.Controls.Add(Me.TreeView1)
       Me.TreeView1.Dock = DockStyle.Fill
End Sub

At design time you can just drag the TreeView control into the ButtonBarGroup directly.

5) Run the project.
