有什么错？
我用一个页面实现新增和修改的功能，想在操作成功后给个提示后转到另一页，但是在新增时不给提示也无任何反应（实际已操作成功），修改时可以，为什么呢？
后台代码
private void btnSubmit_Click(object sender, System.EventArgs e)
{
string [] fields = new string[]{ "ID ", "PID ", "FName ", "Comment ", "isort ", "HID "};
Control [] ctrls = new Control[]{txtID,lsdMayor,txtFName,txtComment,lblIflag};
Config con = new Config(Page);
bool isRun = true;
if (txtID.Text != " ")
{
isRun=con.RunSql(con.GetSQL(fields,ctrls, "querytol ",true,null));
}
else
{
con.TranRunSqlGet(con.GetSQL(fields,ctrls, "querytol ",false,null), "select IDENT_CURRENT( 'querytol ') ",txtID);
}
if(isRun)
{
isRun=con.RunSqlPara(new string []{ "Content "},new object[]{new System.Text.StringBuilder(txtContent.Text)}, "QueryTol ", "ID= "+txtID.Text);
}
con.Close();
if (isRun)
{
Page.RegisterStartupScript( " ", " <SCRIPT language=javascript> alert( '信息提交成功！ ');document.location.href= '../main/ListQuery.aspx?tid= "+lblIflag.Text+ " ' </SCRIPT> ");
}
else
{
con.Fail();
}
}

[解决办法]
先用Response.write输出js来执行alert功能,然后再window.location=xxx.aspx
你是在注册脚本了,而不是运行脚本
