C1Zoom.ManipulationStarting event occurts when the manipulation processor is first created. It means you can handle zoom or pan gesture before C1Zoom process it. For example, if you want to give priority to scrolling ListBox than scrolling the Form, use the following code.
[C#]
|
using C1.Win.TouchToolKit;
private void c1Zoom1_ManipulationStarting(object sender,ZoomManipulationStartingEventArgs e) { if (e.TargetControl is ListBox) { e.Mode = ZoomManipulationModes.Zoom; } else { e.Mode = ZoomManipulationModes.All; } } |
[Visual Basic]
|
Imports C1.Win.TouchToolKit
Private Sub C1Zoom1_ManipulationStarting(sender As System.Object, e AsZoomManipulationStartingEventArgs) Handles C1Zoom1.ManipulationStarting If TypeOf e.TargetControl Is TextBox AndAlso DirectCast(e.TargetControl, TextBox).Text.Length > 0 Then e.Mode = ZoomManipulationModes.Zoom Else e.Mode = ZoomManipulationModes.All End If End Sub |
You can give priority to a TextBox than Form when the TextBox has some text.
