ISupportInitialize Interface

Specifies that this object supports a simple, transacted notification for batch initialization.

Namespace:  System.ComponentModel
Assembly:  System (in System.dll)

'Declaration
Public Interface ISupportInitialize
'Usage
Dim instance As ISupportInitialize

ISupportInitialize allows controls to optimize multiple property assignments. As a result, you can initialize co-dependent properties or batch set multiple properties at design time.

Call the BeginInit method to signal the object that initialization is starting. Call the EndInit method to signal that initialization is complete.

The following code example demonstrates how to use the ISupportInitialize interface to initialize three TrackBar controls.

CType(Me.trackBar1, System.ComponentModel.ISupportInitialize).BeginInit()
CType(Me.trackBar2, System.ComponentModel.ISupportInitialize).BeginInit()
CType(Me.trackBar3, System.ComponentModel.ISupportInitialize).BeginInit()
Me.SuspendLayout()

'trackBar1 

Me.trackBar1.Location = New System.Drawing.Point(160, 400)
Me.trackBar1.Name = "trackBar1" 
Me.trackBar1.TabIndex = 1

'trackBar2 

Me.trackBar2.Location = New System.Drawing.Point(608, 40)
Me.trackBar2.Name = "trackBar2" 
Me.trackBar2.TabIndex = 2

'trackBar3 

Me.trackBar3.Location = New System.Drawing.Point(56, 40)
Me.trackBar3.Name = "trackBar3" 
Me.trackBar3.TabIndex = 3
CType(Me.trackBar1, System.ComponentModel.ISupportInitialize).EndInit()
CType(Me.trackBar2, System.ComponentModel.ISupportInitialize).EndInit()
CType(Me.trackBar3, System.ComponentModel.ISupportInitialize).EndInit()
