Public Event RenderItemCheck As ToolStripItemImageRenderEventHandler

For more information about handling events, see Handling and Raising Events.

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the RenderItemCheck event. This report helps you to learn when the event occurs and can assist you in debugging.

To run the example code, paste it into a project that contains an instance of a type that inherits from ToolStripRenderer, such as a ToolStripSystemRenderer or ToolStripProfessionalRenderer. Then name the instance ToolStripRenderer1 and ensure that the event handler is associated with the RenderItemCheck event.

Private Sub ToolStripRenderer1_RenderItemCheck(sender as Object, e as ToolStripItemImageRenderEventArgs) _ 
     Handles ToolStripRenderer1.RenderItemCheck

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "Image", e.Image)
    messageBoxVB.AppendFormat("{0} = {1}", "ImageRectangle", e.ImageRectangle)
    messageBoxVB.AppendFormat("{0} = {1}", "Graphics", e.Graphics)
    messageBoxVB.AppendFormat("{0} = {1}", "Item", e.Item)
    messageBoxVB.AppendFormat("{0} = {1}", "ToolStrip", e.ToolStrip)
    MessageBox.Show(messageBoxVB.ToString(),"RenderItemCheck Event")

End Sub
