Question

我有一个非常敏感的未解决的错误。请看这个forums，

在asp：linkbutton上单击将打开一个modalPop，如果单击后退按钮，则浏览器会显示＆＃34;文档已过期＆＃34;

Linkbutton在gridview和命令中动态添加，点击动态添加的linkbutton＆＃34; lnkBtnBookTheSelected_Click＆＃34;函数将在那里调用我捕获选定的行ID。

bool CheckAvailability()
{
   //some logical code and getting data in "statusList"
   Session["Availability"] = statusList;
   gridViewAvailability_DataBound(null,null);
}

protected void gridViewAvailability_DataBound(object sender, EventArgs e)
{
   string[]  statusList = (string[])Session["Availability"];
   try
   {

        if (statusList.Length > 0)
        {
             int i = 1;
             foreach (GridViewRow row in gridViewAvailability.Rows)
             {
                 row.Cells[3].Controls.Clear();
                 if (statusList[i - 1] == "Available")
                 {
                      LinkButton lb = new LinkButton();
                      lb.Text = "Book this?";
                      lb.CommandArgument =i.ToString();            
lb.Command+=lnkBtnBookTheSelected_Click;                                                             
                      row.Cells[3].Controls.Add(lb);

             }
             else
             {
                  Label lbl = new Label();
                  lbl.Text ="Not available";
                  row.Cells[3].Controls.Add(lbl);
             }

         }
         i++;
     }

}
catch (Exception a)
{

}
}

protected void lnkBtnBookTheSelected_Click(object sender, CommandEventArgs e)
{    
     Session["SelectedID"] = e.CommandArgument.ToString();    
     lblUserMsgForPurpose.Text = "Dear " + Session["UserName"].ToString() + ", Please enter for what purpose you want to Booking";
     ModalPopupExtenderPurpose.Show();//popup for some input                   
}

来自浏览器的“文档已过期”消息可能是由于在发布表单后回击（单击后回发）。

我建议通过Javascript在ModalPopupExtender上调用show，而不是进行完整的回发。

<script type='text/javascript'>
   function showPopup() {
      $find('ModalPopupExtenderPurpose').show();
   }
</script>

然后，在你的LinkButton标签中，添加onlick ='showPopup（）;返回0;'

<asp:LinkButton runat='server' id='lnkBtnBookTheSelected' Text='Show Popup' onclick='showPopup();return 0;' />

您可以在同一个javascript函数中操作所需的任何其他HTML。

链接按钮单击打开modalpopup，浏览器返回按钮导致＆＃34;文档已过期＆＃34;
