点击button按钮 页面为空

[wujilin]

我做了修改密码的页面

当修改成功后弹出一个
Response.Write(" <script>window.alert('修改成功！') </script>");

可是 页面背景换成了白色空白的
我想让它不变 有上面办法

protected void Button1_Click(object sender, EventArgs e)
{
try
{
DataBaseM DBM = new DataBaseM();
String sqlString = "select count(*) from UTC_Userinfo where UserPass = '" + this.TextBox1.Text.ToString().Trim() + "' and UserName ='" + Session["name"].ToString().Trim() + "'";
if (DBM.RunProcGetNumber(sqlString)>0)
{
String sqlString2 = "update UTC_Userinfo set UserPass = '" + this.TextBox2.Text.ToString().Trim() + "' where UserPass = '" + this.TextBox1.Text.ToString().Trim() + "' and UserName ='" + Session["name"].ToString().Trim() + "'";
DBM.RunProc(sqlString2);
Response.Write(" <script>window.alert('修改成功！') </script>");

}
else
{
Response.Write(" <script>window.alert('密码错误！') </script>");

}

}
catch (Exception ex)
{

}


}

有什么方法解决

[阿非]

ClientScript.RegisterStartupScript(GetType(), "alert", "<script>window.alert('密码错误！') </script>");

[sprc_lcl]

Response.Write
改为：RegisterClientScriptBlock("aa", "<script>window.alert('修改成功！') </script>");

[xiaoqhuang]

Response.Write(" <script>window.alert('修改成功！') </script>");
换成
Page.RegisterStartupScript("alert", "<script>window.alert('修改成功！') </script>");
try.

用response.write后网页的样式会变的，所以尽量别用
