I would like to know if there is a way to create a composite server control that includes:

GridPanel, Store, Paging Toolbar in only one server control, that means avoid to declare

First: Store,
Second: GridPanel,
Third: PagingToolbar

I'll like to declare a GridPanel that include these properties for example :

<ext:GridPanel ID="GridPanel1" runat="server" Header="true" Title="Movements" PagingToolbar="true" PageSize="10">
And for example

GridPanel.dataSource=List<....>; instead of Store.dataSource


It's posible...??
