event System::Windows::Forms::ToolStripItemImageRenderEventHandler ^ RenderItemCheck;public event System.Windows.Forms.ToolStripItemImageRenderEventHandler RenderItemCheck;member this.RenderItemCheck : System.Windows.Forms.ToolStripItemImageRenderEventHandler Public Custom Event RenderItemCheck 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 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 void ToolStripRenderer1_RenderItemCheck(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(), "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.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(),"RenderItemCheck Event")
End Sub
