I don't see any Clear() method listed for GridView Methods.

If you want to clear the current rows in a GridView, the answer you linked to above is the way to do it:

'VB.NET
GridView1.DataSource = Nothing
GridView1.DataBind()

//C#
GridView1.DataSource = null;
GridView1.DataBind();

If the above isn't working for you, please update your question with the code and what error, if any, you're seeing.

If you want to delete the rows of a gridview you can use this: Gridview1.Rows.Clear();
