TreeView / Expand Animation

Configuration
Expand Animation
  • select
Collapse Animation
  • select
  • Software
  • Books
  • Music
  • Movies

  • You can customize the way the child TreeNodes expand or collapse.

    The ExpandAnimation and CollapseAnimation tags of the RadTreeView object control the expand/collapse animations.

    For each expand or collapse animation, you can specify its Type and Duration:

    • The Type is chosen from a list of predefined animation effects.
    • The Duration is set in milliseconds.

    To disable the animation effects, set the Type to AnimationType.None. 

        <telerik:RadTreeView ID="RadTreeView1" runat="server" Skin="Vista"/>
        <ExpandAnimation Type="OutQuart" Duration="300" />
        <CollapseAnimation Type="OutQuint" Duration="200" />
        ...
    </telerik:RadTreeViewu>
