控制按钮到Datagridview

Question

我是这里的新成员。我想要问一些事。祝大家回答我的问题。对不起，我的英语不好。我来自印度尼西亚。 我有两个单选按钮，两个文本框，两个datagridview和一个按钮。该场景是我的第一个文本框是由InvoiceNumber输入，第二个文本框由AccountNumber输入。我的问题是当我通过Invoicenumber输入，然后单击按钮搜索时，将显示Invoicenumber的datagridview，当我通过Accountnumber输入Accounrnumber的datagridview时，将显示。这是我的代码：

尝试是这样的

HTML代码（.aspx页）

<div> 
     <asp:TextBox ID="txtInvoice" runat="server" /> 
     <asp:TextBox ID="txtAccountNo" runat="server" /> 
     <asp:Button id="btnSubmit" runat="server" Text="Submit" OnClick="btnSubmit_Click" /> 
    </div> 

    <div> 
     <asp:GridView ID="gv" runat="server" AutoGenerateColumns="true" />    
    </div>
