Deactivate zoom Tool and currently active tool

Disable Zoom Tool

By default, we can press Ctrl+Shift+P keys to disable the zoom functionality and enable the normal selection cursor in the diagram control.

However, we can use the Esc key to disable the currently active tool at the application level. Since we need to use the Diagram’s KeyPress event to cancel the currently active tool by using the 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 void 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
