Deactivate zoom Tool and currently active tool

Disable Zoom tool
By default, we can press Ctrl+Shift+P keys to disable zoom functionality and to enable normal selection cursor in diagram control.
However, we can use Esc key to disable currently active tool in application level. Since, we need to use Diagram’s KeyPress event to cancel the currently active tool by using Diagram.Controller’s “DeactivateTool()” method.
The following code example is used to disable currently active tool (i.e. ZoomTool).
[C#]
//Registering the event to the diagram controller
diagram1.KeyPress += diagram1_KeyPress;
Private Sub diagram1_KeyPress(ByVal sender As object, ByVal e As KeyPressEventArgs)
{
if (e.KeyChar == Convert.ToChar((char)(Keys.Escape)))
{
diagram1.Controller.DeactivateTool(diagram1.Controller.ActiveTool);
}
}
[VB]
'Registering the event to the diagram controller AddHandler diagram1.KeyPress, AddressOf diagram1_KeyPress Private Sub diagram1_KeyPress(ByVal sender As Object, ByVal e As KeyPressEventArgs) If e.KeyChar = CChar(ChrW(Keys.Escape)) Then diagram1.Controller.DeactivateTool(diagram1.Controller.ActiveTool) End If End Sub
