Detecting Auto Showing

You can use the C1Zoom.ControlAutoShowing event to determine the cancelation of the control's Auto Showing based on the cause of the event.

For example, you can cancel the auto scroll of the Form when the control is partially displayed.

Imports C1.Win.TouchToolKit
 Private Sub C1Zoom1_ControlAutoShowing(sender As System.Object, e As ControlAutoShowingEventArgs) Handles C1Zoom1.ControlAutoShowing
    ' Do not auto scroll if a control is displayed
    If C1Zoom1.GetDisplayRectangle(e.Showinc1ontrol).Size = e.Showinc1ontrol.Size Then
        e.Cancel = True
    End If
     ' Do not auto scroll if a control is partial displayed
    If C1Zoom1.GetDisplayRectangle(e.Showinc1ontrol).IsEmpty Then
        e.Cancel = True
    End If
     ' Do not auto scroll if a control's most part is shown
    If C1Zoom1.GetDisplayRectangle(e.Showinc1ontrol).Size.Height > 30 Then
        e.Cancel = True
    End If
End Sub

using C1.Win.TouchToolKit;
private void C1Zoom1_ControlAutoShowing(object sender, ControlAutoShowingEventArgs e)
{
    // Do not auto scroll if a control is displayed
    if (C1Zoom1.GetDisplayRectangle(e.Showinc1ontrol).Size == e.Showinc1ontrol.Size)
    {
        e.Cancel = true;
    }
 
    // Do not auto scroll if a control is partial displayed
    if (!C1Zoom1.GetDisplayRectangle(this.button1).IsEmpty)
    {
        e.Cancel = true;
    }
 
    // Do not auto scroll if a control's most part is shown
    if (C1Zoom1.GetDisplayRectangle(this.button1).Size.Height > 30)
    {
        e.Cancel = true;
    }
}
