Switch two gridViews, but put in the same place, how to do it ?

if click_button1, then gridView1.visible=true

if click_button2, then show gridView2.visible=true

but, How to layout them in myFile.aspx ? I want to show them in the same place, switch from one to another ?

Just place them one after the other

<asp:GridViewID="GridView1"runat="server"> ...</asp:GridView><asp:GridViewID="GridView2"runat="server"> ... </asp:GridView>

Then in the button 1 event handler you have:

GridView1.Visible = true;
GridView2.Visible = false;

Mark as ANSWER. Thanks.
