<强> ASPX：

<asp:TextBox ID="TextBox1" clientidmode="Static" runat="server" onkeypress="return EnterEvent(event)"></asp:TextBox>    
<asp:Button ID="Button1" runat="server" style="display:none" Text="Button" />

<强> JS：

function EnterEvent(e) {
        if (e.keyCode == 13) {
            __doPostBack('<%=Button1.UniqueID%>', "");
        }
    }

<强> CS：

 protected void btnGo_Click(object sender, EventArgs e)
{
    try
    {
        SearchHint = txtName.Text.Split('[')[0].ToString().Trim();
        WebUtility.SetCookie(Response, "gslCountry", WebUtility.GetDropDownListValue(ddlCountry, String.Empty), false);
        WebUtility.SetCookie(Response, "gslState", WebUtility.GetDropDownListValue(ddlState, String.Empty), false);
        WebUtility.SetCookie(Response, "gslName", txtName.Text, false);
        WebUtility.SetCookie(Response, "gslCity", txtCity.Text, false);
        BindGrid();
