The following code example adds two buttons to a form. The example transactions the addition of the buttons by using the SuspendLayout and ResumeLayout methods.
private:
void AddButtons()
{
// Suspend the form layout and add two buttons.
this->SuspendLayout();
Button^ buttonOK = gcnew Button;
buttonOK->Location = Point(10,10);
buttonOK->Size = System::Drawing::Size( 75, 25 );
buttonOK->Text = "OK";
Button^ buttonCancel = gcnew Button;
buttonCancel->Location = Point(90,10);
buttonCancel->Size = System::Drawing::Size( 75, 25 );
buttonCancel->Text = "Cancel";
array<Control^>^temp5 = {buttonOK,buttonCancel};
this->Controls->AddRange( temp5 );
this->ResumeLayout();
}
private void AddButtons()
{
// Suspend the form layout and add two buttons.

Button buttonOK = new Button();
buttonOK.Location = new Point(10, 10);
buttonOK.Size = new Size(75, 25);

Button buttonCancel = new Button();
buttonCancel.Location = new Point(90, 10);
buttonCancel.Size = new Size(75, 25);
buttonCancel.Text = "Cancel";
this.Controls.AddRange(new Control[]{buttonOK, buttonCancel});
this.ResumeLayout();
}
Private Sub AddButtons()
' Suspend the form layout and add two buttons.
Me.SuspendLayout()
Dim buttonOK As New Button()
buttonOK.Location = New Point(10, 10)
buttonOK.Size = New Size(75, 25)
buttonOK.Text = "OK"
Dim buttonCancel As New Button()
buttonCancel.Location = New Point(90, 10)
buttonCancel.Size = New Size(75, 25)
buttonCancel.Text = "Cancel"
Me.Controls.AddRange(New Control() {buttonOK, buttonCancel})
Me.ResumeLayout()
End Sub
Remarks
The layout logic of the control is suspended until the ResumeLayout method is called.
The SuspendLayout and ResumeLayout methods are used in tandem to suppress multiple Layout events while you adjust multiple attributes of the control. For example, you would typically call the SuspendLayout method, then set the Size, Location, Anchor, or Dock properties of the control, and then call the ResumeLayout method to enable the changes to take effect.
There must be no pending calls to SuspendLayout for ResumeLayout to be successfully called.
Note
When adding several controls to a parent control, it is recommended that you call the SuspendLayout method before initializing the controls to be added. After adding the controls to the parent control, call the ResumeLayout method. This will increase the performance of applications with many controls.
