Validate() function doesn't fire
问题 Here is my button. <asp:Button ID="btnNext" runat="server" Text="Next" Style="display: none" OnClick="btnNext_Click" CausesValidation="true" ValidationGroup="vgLinR"/> When I write ValidationGroup="vgLinR" in aspx side validation works. But I have 2 different validation group. So I need fire these 2 validation group in one button. so I write that code at code behind : protected void btnNext_Click(object sender, EventArgs e) { Page.Validate("vgLinR"); Page.Validate("vgLogR"); } but it doesn't
