By default a context menu appears when the C1PreviewPane is right-clicked at run time. This ContextMenuStrip includes settings for manipulating the preview including items from the File, Zoom, and Text toobars. You can create your own context menu by adding a ContextMenuStrip control and assigning it to the PreviewPane.ContextMenuStrip property. You can also customize the existing ContextMenuStrip by adding additional items or removing existing items.
The following example removes the standard "Copy" item from the context menu. Complete the following steps:
1. In the Form_Load event attach a handler to the Opening event of the ContextMenuStrip on the C1PreviewPane:
AddHandler PreviewPane.ContextMenuStrip.Opening, AddressOf ContextMenuStrip_Opening
• C#
PreviewPane.ContextMenuStrip.Opening += new CancelEventHandler(ContextMenuStrip_Opening);
2. Create the ContextMenuStrip_Opening event, and add the following code to remove the "Copy" item from the context menu:
Private Sub ContextMenuStrip_Opening(ByVal sender As Object, ByVal e As CancelEventArgs)
Dim cms As System.Windows.Forms.ContextMenuStrip = DirectCast(sender, System.Windows.Forms.ContextMenuStrip)
For Each item As ToolStripItem In cms.Items
If item.Tag = ContextMenuTags.Copy Then
item.Visible = False
End If
Next
End Sub
• C#
void ContextMenuStrip_Opening(object sender, CancelEventArgs e)
{
System.Windows.Forms.ContextMenuStrip cms = (System.Windows.Forms.ContextMenuStrip)sender;
foreach (ToolStripItem item in cms.Items)
if (item.Tag == ContextMenuTags.Copy)
item.Visible = false;
}
What You've Accomplished
When you right-click the preview pane in the C1PrintPreviewControl control, observe that the standard "Copy" item is not included on the context menu.
