This walkthrough is split up into the following activities:

• Adding a protected enumeration to frmDesigner
• Adding code to the frmDesigner_Load event
• Adding code to the Designer1_SelectionChanged event

Adding a protected enumeration to frmDesigner

To write the code in Visual Basic

• Right-click in any section of frmDesigner, and click on View Code to display the code view for the Windows Form. Add the following code just below the "Windows Form Designer generated code" region.

To write the code in C#

• Double-click anywhere on frmDesigner to show the code view for the Windows Form. Add the following code just below the "Windows Form Designer generated code" region.

  The following example shows what the code for the method looks like.

  ' Visual Basic
  Protected Enum toolbarModes
          singleControl
          twoControls
          multiControls
          noControls
  End Enum

  //C#
  protected enum toolbarModes
  {
  	singleControl,
  	twoControls,
  	multiControls,
  	noControls,
  }

Adding code to the frmDesigner_Load event

To write the code in Visual Basic

• Right-click in any section of frmDesigner, and click on View Code to display the code view for the Windows Form. At the top left of the code view for frmDesigner, click the drop-down arrow and select (Base Class Events). At the top right of the code window, click the drop-down arrow and select Load. This creates an event-handling method for the frmDesigner_Load event.

To write the code in C#

• Click at the top of frmDesigner to select the Windows Form. Click on the events icon in the Properties window to display available events for the section. Double-click Load. This creates an event-handling method for the frmDesigner_Load event.

  The following example shows what the code for the method looks like.

  ' Visual Basic
  
  Dim i As Integer
  Dim cnt As Integer
  Dim ctl As String
  Dim doStatusChange As Boolean
  Private Sub frmDesigner_Load(ByVal sender As Object, ByVal e As System.EventArgs) _
  	Handles MyBase.Load
          Me.fillClassName()
          Me.fillFonts()
          Me.fillFontSizes()
          Me.setModes(toolbarModes.noControls)
          Me.Designer1.Focus()
          
          AddHandler Application.Idle, AddressOf Me.Idle
  End Sub

  //C#
  
  bool doStatusChange;
  private void frmDesigner_Load(object sender, System.EventArgs e)
  {
  	this.fillClassName();
  	this.fillFonts();
  	this.fillFontSizes();
  	this.setModes(toolbarModes.noControls);
  	this.designer1.Focus();
  
  	Application.Idle += new System.EventHandler(this.Idle);
  }

Adding code to the Designer1_SelectionChanged event

To write the code in Visual Basic

• Right-click in any section of frmDesigner, and click on View Code to display the code view for the Windows Form. At the top left of the code view for frmDesigner, click the drop-down arrow and select designer1. At the top right of the code window, click the drop-down arrow and select SelectionChanged. This creates an event-handling method for the Designer1_SelectionChanged event.

To write the code in C#

• Click in the designer window of frmDesigner to select Designer1. Click on the events icon in the Properties window to display available events for the section. Double-click SelectionChanged. This creates an event-handling method for the Designer1_SelectionChanged event.

  The following example shows what the code for the method looks like.

  ' Visual Basic
   Private Sub Designer1_SelectionChanged() Handles Designer1.SelectionChanged
          selChangeReportToolbar()
          selChangeLayoutToolbar()
          selChangePropGrid()
  End Sub

  //C#
  private void designer1_SelectionChanged()
  {
  	selChangeReportToolbar();
  	selChangeLayoutToolbar();
  	selChangePropGrid();
  }
