    AllowUserZoom Property (FpSpread)
    In This Topic
    Gets or sets whether the user can scale the display of the component using the Ctrl key and the mouse wheel.
    Syntax
    'Declaration
     
    Public Property AllowUserZoom As Boolean
    'Usage
     
    Dim instance As FpSpread
    Dim value As Boolean
     
    instance.AllowUserZoom = value
     
    value = instance.AllowUserZoom
    public bool AllowUserZoom {get; set;}

    Property Value

    Boolean: true if the user is allowed to scale the display; false otherwise
    Remarks

    If you set this property to false, users cannot zoom in or out by clicking the mouse while the pointer is over a preview page. However, you can still provide other means to let users zoom, such as a button that changes the ZoomFactor property.

    This property is available at run time only.

    Example
    This example specifies whether the user can zoom in the Spread component by using the Control (Ctrl) key and the mouse wheel.
    FarPoint.Win.Spread.FpSpread fpSpread1 = new FarPoint.Win.Spread.FpSpread();
    FarPoint.Win.Spread.SheetView shv = new FarPoint.Win.Spread.SheetView();
    fpSpread1.Location = new Point(10, 10);
    fpSpread1.Height = 200;
    fpSpread1.Width = 400;
    Controls.Add(fpSpread1);
    fpSpread1.Sheets.Add(shv);
    fpSpread1.AllowUserZoom = true;
    Dim fpSpread1 As New FarPoint.Win.Spread.FpSpread()
    Dim shv As New FarPoint.Win.Spread.SheetView()
    fpSpread1.Location = New Point(10, 10)
    fpSpread1.Height = 200
    fpSpread1.Width = 400
    Controls.Add(fpSpread1)
    fpSpread1.Sheets.Add(shv)
    fpSpread1.AllowUserZoom = True
