在用户控件中使用占位符为gridview保留位置

Question

I have a user control that I want reserve a place inside it for filling by a GridView by each target pages.

I am using place holder and ITemplate to provide this option for my user control.

Q1: How can I force my place holder to accept just GridView tag inside it?

Q2: Or in ideal mode, is there a way that I can use place holder inside the grid? It means I write ASP:GridView tag in user control and write columns of it in target each pages.
