会话值无法清除 [英] session value can not clear

问题描述

我参加了两场比赛。在弹出窗口中我想破坏会话但不能。

I have take two session. In the popup I want to destroy the session but can not.

Session["StyleNo"] = ddlStyleNo.SelectedValue.ToString().Trim();
        Session["DefectNo"] = ddlDefectType.SelectedValue.ToString().Trim();
        ScriptManager.RegisterStartupScript(this, typeof(string), "OPEN_WINDOW", "var Mleft = (screen.width/2)-(760/2);var Mtop = (screen.height/2)-(700/2);window.open( 'Reports/Smt_StyleWiseReportWindow.aspx?', null, 'height=700,width=760,status=yes,toolbar=no,scrollbars=yes,menubar=no,location=no,top=\'+Mtop+\', left=\'+Mleft+\'' );", true);

在弹出代码中我尝试了不同的三种方式在最后阻止但没有工作。

In popup codes I tried different three ways in finally block but none work.

finally
{
Session["StyleNo"] = null;
Session["StyleNo"] = "";
Session.Remove("StyleNo");
}

推荐答案

你可以使用session.clear（）;

It will give clear idea.. :)

在那段代码之后我清除了下拉菜单

After that code I clear the dropdown

Session["StyleNo"] = ddlStyleNo.SelectedValue.ToString().Trim();
        Session["DefectNo"] = ddlDefectType.SelectedValue.ToString().Trim();
        ScriptManager.RegisterStartupScript(this, typeof(string), "OPEN_WINDOW", "var Mleft = (screen.width/2)-(760/2);var Mtop = (screen.height/2)-(700/2);window.open( 'Reports/Smt_StyleWiseReportWindow.aspx?', null, 'height=700,width=760,status=yes,toolbar=no,scrollbars=yes,menubar=no,location=no,top=\'+Mtop+\', left=\'+Mleft+\'' );", true);

ddlStyleNo.Items.Clear();
ddlDefectType.Items.Clear();
