public:
event System::Windows::Forms::ToolStripItemImageRenderEventHandler ^ RenderItemImage;public event System.Windows.Forms.ToolStripItemImageRenderEventHandler RenderItemImage;member this.RenderItemImage : System.Windows.Forms.ToolStripItemImageRenderEventHandler Public Custom Event RenderItemImage As ToolStripItemImageRenderEventHandler Event Type
Examples
The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the RenderItemImage 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 RenderItemImage event.
private void ToolStripRenderer1_RenderItemImage(Object sender, ToolStripItemImageRenderEventArgs e) {
System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Image", e.Image );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ImageRectangle", e.ImageRectangle );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Graphics", e.Graphics );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Item", e.Item );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "ToolStrip", e.ToolStrip );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "RenderItemImage Event" );
}
Private Sub ToolStripRenderer1_RenderItemImage(sender as Object, e as ToolStripItemImageRenderEventArgs) _
Handles ToolStripRenderer1.RenderItemImage
Dim messageBoxVB as New System.Text.StringBuilder()
messageBoxVB.AppendFormat("{0} = {1}", "Image", e.Image)
messageBoxVB.AppendLine()
messageBoxVB.AppendFormat("{0} = {1}", "ImageRectangle", e.ImageRectangle)
messageBoxVB.AppendLine()
messageBoxVB.AppendFormat("{0} = {1}", "Graphics", e.Graphics)
messageBoxVB.AppendLine()
messageBoxVB.AppendFormat("{0} = {1}", "Item", e.Item)
messageBoxVB.AppendLine()
messageBoxVB.AppendFormat("{0} = {1}", "ToolStrip", e.ToolStrip)
messageBoxVB.AppendLine()
MessageBox.Show(messageBoxVB.ToString(),"RenderItemImage Event")
End Sub
