Group expand/collapse client event does not happen

[Matt]

Hi,
I have the following code snippets:

radGrid.ShowGroupPanel = true;
radGrid.MasterTableView.GroupLoadMode = GridGroupLoadMode.Client;
radGrid.ClientSettings.AllowDragToGroup = true;
radGrid.ClientSettings.AllowExpandCollapse = true;
radGrid.ClientSettings.ClientEvents.OnGroupExpanded = "GroupExpanded";
radGrid.ClientSettings.ClientEvents.OnGroupCollapsed = "GroupCollapsed";
radGrid.GroupingSettings.ShowUnGroupButton = true;

The GroupExpanded and GroupCollapsed never  happens, I tried:

function GroupExpanded(s, e) {
    alert('GroupExpanded');
}

Nothing happens.

Am I missing something?
Thanks

Matt:

Try modifying your code as follows:

// from
radGrid.ClientSettings.AllowExpandCollapse = true;

// to
radGrid.ClientSettings.AllowGroupExpandCollapse = true;

Referenceing the Grid / Client Group Load online demo that states in the description area:

You can control where the grouping will be handled using the GroupLoadMode property of the GridTableView instance. There are two options: 

- Server-side - GridTableView.GroupLoadMode.Server - this is the default behavior. Groups are expanded after postback to the server for example: 

<MasterTableView GroupLoadMode="Server"> 

- Client-side - GridTableView.GroupLoadMode.Client - Groups will be expanded client-side and no postback will be performed. 

<MasterTableView GroupLoadMode="Client"> 

and set the ClientSettings -> AllowGroupExpandCollapse attribute to true: 

<ClientSettings AllowGroupExpandCollapse="True"> 

I have the events firing in my demo. See "radgridgroupcollapsedevent.png " and "radgridgroupexpandedevent.png" screenshots.

Hope this helps!
