问题描述

大家好

Hi All

protected void btnPreview_Click(object sender, EventArgs e)
    {

        ArrayList array = new ArrayList();

        array.Add(txtAD.Text);
        array.Add(txtASO.Text);
        array.Add(txtController.Text);
        array.Add(txtGPS.Text);
        array.Add(txtTAP.Text);

        Session["ArrayList"] = array;
        ViewState["ArrayList"] = array;
        Response.Redirect("~/Preview.aspx");

}
到现在为止都很好

在预览"页面中，我有一个编辑"按钮.通过单击我将再次将我的页面重定向到上一页..那里的文本框值不存在..
我想在不同页面加载之间保留文本框值..

我知道我应该使用视图状态.但是无法实现它们.
请帮助我.

谢谢

推荐答案

您不应该使用ViewState，因为要在不同的页面之间导航.改为使用会话.

You shouldn''t use ViewState because you''re navigating between different pages. Use Session instead.

我同意Jim

以这种方式尝试

i agree with Jim

try in this way

On Click Of btnPreview
session["Name"]=Convert.tostring(txt.text);

Redirect to nextPage 

//do your work 

Redirect to previous Page 

//in the Page Load Check 

if(session["Name"]!=null)
TextBox1.text = Session["Name"];
//clear that Session 

Session["Name"]=null;
Session.clear();
