PanelBar / Expand Animation

Configuration
Expand Animation
Collapse Animation

  • You can customize the way the panel-items expand and collapse.

    The ExpandAnimation and CollapseAnimation tags of RadPanelBar are used to customize the way groups are expanded and collapsed. For each expand or collapse animation, you can specify Type and Duration:

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

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

    The ExpandDelay and CollapseDelay properties set the period of time (in milliseconds) between clicking the item and the children starting to expand or collapse respectively.

        <telerik:RadPanelBar ID="RadPanelBar1" runat="server"/>
        <ExpandAnimation Type="OutQuart" Duration="300" />
        <CollapseAnimation Type="OutQuint" Duration="200" />
        ...
    </telerik:RadPanelBar>
