Control Button to Datagridview - asp.net

Question

I'm a new member here. I want to ask something. Best regards for everyone of you to answer my questions. Sorry for my bad English. I'm from Indonesia.
I have two radiobutton, two textbox, two datagridview and one button. The scenario is my first textbox is Input by InvoiceNumber and the second Textbox input by AccountNumber. My question is when I input by Invoicenumber and I click Button Search the datagridview for Invoicenumber will show and when I input by Accountnumber the datagridview for Accounrnumber will show. This is my Code:

Try something like this
HTML Code (.aspx page)
<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>
**Code Behind**
protected void btnSubmit_Click(object sender, EventArgs e)
{
if (!string.IsNullOrEmpty(txtInvoice.Text.Trim())) {
gv.DataSource = getInvoiceDetails(txtInvoice.Text);
gv.DataBind();
}
else if (!string.IsNullOrEmpty(txtAccountNo.Text.Trim()))
{
gv.DataSource = getAccountDetails(txtInvoice.Text);
gv.DataBind();
}
}
private DataTable getInvoiceDetails(string invoiceNo) {
DataTable dt = new DataTable();
using (SqlConnection con = new SqlConnection(connectionString)) {
using (SqlCommand cmd = new SqlCommand("YourQueryToGetInvoiceDetails")) {
SqlDataAdapter adapter = new SqlDataAdapter(cmd);
adapter.Fill(dt);
return dt;
}
}
}
private DataTable getAccountDetails(string invoiceNo)
{
DataTable dt = new DataTable();
using (SqlConnection con = new SqlConnection(connectionString))
{
using (SqlCommand cmd = new SqlCommand("YourQueryToGetAmountDetails"))
{
SqlDataAdapter adapter = new SqlDataAdapter(cmd);
adapter.Fill(dt);
return dt;
}
}
}
