Answer 1

Put this code in your Code behind.

Public Overloads Overrides Sub VerifyRenderingInServerForm(ByVal control As Control)


End Sub

Answer 2

Make sure that the ContentPlaceholder is inside

<form runat="server">


</form>

Answer 3

A gridview must be placed in a server-side form.

<form id="frm" runat="server">
<asp:gridview />
</form>

That form can either reside on the content page, or it must surround the content placeholder on the master page. It must be one or the other - you can only have one server side form on a page.
