用户控件有一个名为.Page的属性，你可以从中使用
FindControl方法
thisControl.Page.FindControl（" myDataGridID"）

The user control has a property called .Page from which you can use the
FindControl method
thisControl.Page.FindControl("myDataGridID")

您可以在页面上创建一个公共函数，该函数返回对
数据网格的引用。 />
然后从你的用户控件中你可以说：
Dim dg as datagrid = Page.MyDataGridFunction（）

You could make a public function on the page that returns a reference to the
datagrid.
Then from within your user control you could say:
Dim dg as datagrid = Page.MyDataGridFunction()

thisControl.Page.FindControl("myDataGridID")
请注意这应该是
Page.FindControl（" myDataGridID"）
来自用户控件.....
