Assembly: DevExpress.Xpf.Grid.v24.2.dll

NuGet Package: DevExpress.Wpf.Grid.Core

Declaration

VB.NET

Public Property AllowPerPixelScrolling As Boolean

Property Value

Type	Description
Boolean	true to enable per-pixel scrolling; false to enable row by row scrolling.

Remarks

Note

If per-pixel scrolling is enabled and data rows are of different height, the last (bottom) visible row may not be displayed entirely.

Example

This example shows how to implement a custom animation displayed when a user vertically scrolls the GridControl (per-pixel scrolling):

1. Set the TableView.AllowScrollAnimation property to true.
2. Set the TableView.ScrollAnimationMode property to Custom.
3. Handle the TableView.CustomScrollAnimation event and specify a custom scroll animation.

View Example: Implement Custom Scroll Animation

XAML

<dxg:GridControl Name="grid" AutoGenerateColumns="AddNew">
    <dxg:GridControl.View>
        <dxg:TableView Name="view"
                       AutoWidth="True"
                       AllowScrollAnimation="True"
                       ScrollAnimationMode="Custom"
                       CustomScrollAnimation="view_CustomScrollAnimation"/>
    </dxg:GridControl.View>
</dxg:GridControl>

C#

void view_CustomScrollAnimation(object sender, DevExpress.Xpf.Grid.CustomScrollAnimationEventArgs e) {
    e.Storyboard = new Storyboard();
    DoubleAnimation animation = new DoubleAnimation {
        From = e.OldOffset,
        To = e.NewOffset,
        Duration = new Duration(TimeSpan.FromMilliseconds(600)),
        EasingFunction = new ExponentialEase() { Exponent = 0 }
    };
    e.Storyboard.Children.Add(animation);
}

VB.NET

Private Sub view_CustomScrollAnimation(ByVal sender As Object, ByVal e As DevExpress.Xpf.Grid.CustomScrollAnimationEventArgs)
    e.Storyboard = New Storyboard()
    Dim animation As DoubleAnimation = New DoubleAnimation With {.From = e.OldOffset, .[To] = e.NewOffset, .Duration = New Duration(TimeSpan.FromMilliseconds(600)), .EasingFunction = New ExponentialEase() With {.Exponent = 0}}
    e.Storyboard.Children.Add(animation)
End Sub
