Public Property ScrollAnimationMode As ScrollAnimationMode
| Type | Description |
|---|---|
| ScrollAnimationMode |
A ScrollAnimationMode enumeration value that specifies the per-pexel scrolling mode.
|
Available values:
| Name | Description |
|---|---|
| EaseOut |
Starts quickly and then decelerates.
| | Linear |
Moves smoothly.
| | EaseInOut |
Starts slowly, accelerates and then decelerates.
| | Custom |
A custom animation effect implemented within the TableView.CustomScrollAnimation event handler (TreeListView.CustomScrollAnimation in TreeListView).
|
To provide a visual effect for per-pixel scrolling, set the TreeListView.AllowScrollAnimation property to true. The ScrollAnimationMode and TreeListView.ScrollAnimationDuration properties allow you to customize the animation. The first property specifies the scrolling mode, the second property specifies the animation length.
This example shows how to implement a custom animation displayed when a user vertically scrolls the GridControl (per-pixel scrolling):
true.Custom.View Example: Implement Custom Scroll Animation
<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>
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);
}
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
