You can apply templates to the RadToolBarButton and RadToolBarSplitButton.
        You can embed any content inside a template:
    
        - HTML markup 
- ASP.NET server controls 
- Third-party controls (other Telerik controls as well) 
        Use the following syntax to specify a template for RadToolBarButton:
    <telerik:RadToolBarButton>
	<ItemTemplate>
		<div style="font:bold 11px Tahoma;">
			Name:
			<asp:TextBox id="txtName" runat="server"></asp:TextBox>
		</div>
	</ItemTemplate>
</telerik:RadToolBarButton>
    
        As only RadToolBarButton supports databinding, binding expressions
        in RadToolBarSplitButton templates are not evaluated.
