前台:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="test2.aspx.cs" Inherits="WebApplication1.test2" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:ScriptManager ID="ScriptManager1" runat="server">
        </asp:ScriptManager>  
        <asp:UpdatePanel runat="server" ID="updatePanel2">
            <ContentTemplate>
                <asp:TextBox ID="txtCompanyCd" runat="server" OnTextChanged="txtChanged" AutoPostBack="true"></asp:TextBox>
                <asp:TextBox ID="txtUserNm" runat="server" ></asp:TextBox>               
            </ContentTemplate>
            <Triggers>
                <asp:AsyncPostBackTrigger ControlID="txtCompanyCd" EventName="textChanged" />               
            </Triggers>
        </asp:UpdatePanel>

    </div>
    </form>
</body>
</html>

 

后台:

        protected void txtChanged(object sender, EventArgs e)
        {
            txtUserNm.Text = "test";
        }

 

错误提示的时候,注意要用:

 

     ScriptManager.RegisterStartupScript(this.updatePanel2, this.GetType(), "sucess", "alert('登録完了しました。')", true);

 

不能用:  this.ClientScript.RegisterStartupScript(GetType(), "getUserInfo", “alert(3434)”, true);
