Telerik.Web.UI.GridDataItemEventArgs OnHierarchyCollapsed Property

note

To get or set property values for client API properties, you must call property accessor methods that are named with the get_ and set_ prefixes. For example, to get or set a value for a property such as cancel, you call the get_cancel or set_cancel.

This event is fired when the hierarchy has been collapsed and the HierarchyLoadMode setting is set to Client.

Fired by RadGrid
Arguments id - id of the RadGrid item that has raised the event itemIndexHierarchical - hierarchical index of the item that has raised the event gridDataItem - the corresponding data item tableView - owner TableView of the item that has raised the event dataKeyValues - data key value for the item that has raised the event domEvent - dom event that was raised for the current event
Can be canceled No

Example:

<telerik:RadGrid RenderMode="Lightweight" ID="RadGrid1" runat="server">
    <ClientSettings>
        <ClientEvents OnHierarchyCollapsed="HierarchyCollapsed" />
    </ClientSettings>
</telerik:RadGrid>
function HierarchyCollapsed(sender, eventArgs) {
    alert("Row: " + eventArgs.get_itemIndexHierarchical() + " was collapsed");
}
note

get_gridDataItem() is not directly available on the client unless OnRowCreating/OnRowCreated events are hooked up. This is done for optimization purpose. If you need the rowIndex, you can use eventArgs.get_itemIndexHierarchical()
