Bind/naviagte menu items in web forms (ASP.net)

问题

I am new to ASP.net web forms. Please help me for following issue.

Dragged menu control in the design. Edited menu items with its sub items. I have a grid view with the data bound to the database. When I select the sub menu item the gridview with the data should be shown below the menu. How to show he gridview when I select a menu item

I tried to bind the grid view id but it doesn't work.

      <asp:Menu ID="mini" runat="server" Orientation="Horizontal">
          <Items> <asp:MenuItem Text="Item">
              <asp:MenuItem Text="sdaad" Value="1">
                  <asp:MenuItem Text="MenuSub" Value="MenuSub" ></asp:MenuItem>
                  <asp:MenuItem Text="MenuSub1" Value="MenuSub1" ></asp:MenuItem>
              </asp:MenuItem>
              <asp:MenuItem Text="Item" Value="Item">
                  <asp:MenuItem Text="MenuSub" Value="MenuSub"></asp:MenuItem>
              </asp:MenuItem>
              </asp:MenuItem></Items>
      </asp:Menu>

I want to show the gridview when the menu item is selected

     <asp:GridView ID="GridView1" CssClass="table-condensed" runat="server" DataKeyNames="projectid" OnRowCommand="Unnamed_RowCommand">
        <Columns>
        <asp:TemplateField HeaderText="Proje">
        <ItemTemplate>
        <asp:Label ID="lbfid" runat="server" Text='<%#Eval("projectid")%>'></asp:Label>
        </ItemTemplate>
        </asp:TemplateField>

        <asp:TemplateField HeaderText="Doc">
        <ItemTemplate>
        <asp:Label ID="lbfname" runat="server" Text='<%#Eval("video")%>'></asp:Label>
            <asp:HyperLink runat="server" CommandName="view" CommandArgument='<%#Eval("abstract")%>' >download</asp:HyperLink>

        </ItemTemplate>
        </asp:TemplateField>
            </Columns>

    </asp:GridView>

In my page load event

con.Open();


    SqlDataAdapter sda = new SqlDataAdapter("select * from table", con);
    DataSet ds = new DataSet();
    sda.Fill(ds);
    if (ds.Tables[0].Rows.Count > 0)
    {
        GridView1.DataSource = ds;
        GridView1.DataBind();

    }
    con.Close();

Please help me
