    Using a different Magnifier Window in different controls

    You can use the C1Magnify.MagnifierShowing event to change the Magnifier Window before the window is displayed. In the event, you can use different settings in different controls. Also, you can cancel showing the Magnifier Window when the e.Cancel property is set to True.

    The following code shows a rectangular Magnifier window for a TextBox. It does not show the Magnifier window for NumericUpDown, but it shows a circular Magnifier window for other controls.

    Visual Basic
    Copy Code

    Imports C1.Win.TouchToolKit

    Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load

        C1Magnify1.SetEnableMagnifier(TextBox1, True)

        C1Magnify1.SetEnableMagnifier(NumericUpDown1, True)

    End Sub

    Private Sub C1Magnify1_MagnifierShowing(sender As System.Object, e As C1.Win.TouchToolKit.MagnifierEventArgs) Handles C1Magnify1.MagnifierShowing

        If e.TargetControl Is TextBox1 Then

            Dim magnifier As C1Magnify = DirectCast(sender, C1Magnify)

            magnifier.Shape = MagnifierShape.Rectangle

            magnifier.Size = New Size(200, 30)

        ElseIf e.TargetControl Is NumericUpDown1 Then

            e.Cancel = True

        Else

            Dim magnifier As C1Magnify = DirectCast(sender, C1Magnify)

            magnifier.Shape = MagnifierShape.Circle

            magnifier.Size = New Size(100, 100)

        End If

    End Sub
    C#
    Copy Code

    using C1.Win.TouchToolKit;

     

    private void Form1_Load(object sender, EventArgs e)

    {

        C1Magnify1.SetEnableMagnifier(textBox1, true);

        C1Magnify1.SetEnableMagnifier(numericUpDown1, true);

    }

     

    private void C1Magnify1_MagnifierShowing(object sender, MagnifierEventArgs e)

    {

        if (e.TargetControl == textBox1)

        {

            C1Magnify magnifier = sender as C1Magnify;

            magnifier.Shape = MagnifierShape.Rectangle;

            magnifier.Size = new Size(200, 30);

        }

        else if (e.TargetControl == numericUpDown1)

        {

            e.Cancel = true;

        }

        else

        {

            C1Magnify magnifier = sender as C1Magnify;

            magnifier.Shape = MagnifierShape.Circle;

            magnifier.Size = new Size(100, 100);

        }

    }
