Hello guys,

I have problem about displaying Session value in textbox.

Here is my code:

Inside my page load:

C#

string msgBoxVal = string.Empty;
if (Session["LabelDetails"] != null)
{
  msgBoxVal = (String)Session["LabelDetails"];
  Session.Remove("LabelDetails");
}
if (msgBoxVal != "")
{
  MessageBox("Test1");
  MessageBox("The shipping label is successfully deleted! Deleted label details: " + msgBoxVal);
  MessageBox("Test2");
}

and my code for MessageBox:

C#

private void MessageBox(string msg)
{
  Page.Controls.Add(new LiteralControl("<script language='javascript'> window.alert('" + msg.Replace("'", "\\'") + "')</script>"));
}

This drives me crazy because I am having two alertbox show as Test1 and Test2 but one which is in the middle that I want to show won't appear.

I have double checked that Session is not null and the value gets assigned to msgBoxVal and during the debug mode it doesnt throw an exception. Can someone tell me where I am wrong?

Thanks.

hi tried your code and changed simple small things and i tested the results
try this

C#

protected void Page_Load(object sender, EventArgs e)
   {
       //the line was just to test it
      //Session.Add("LabelDetails", 454);
       string msgBoxVal = string.Empty;
       if (Session["LabelDetails"] != null)
       {
           msgBoxVal = Convert.ToString(Session["LabelDetails"]);
           Session.Remove("LabelDetails");
       }
       if (msgBoxVal != "")
       {
           MessageBox("Test1");
           MessageBox("The shipping label is successfully deleted! Deleted label details: " + msgBoxVal);
           MessageBox("Test2");
       }


   }

   private void MessageBox(string msg)
   {
       Page.Controls.Add(new LiteralControl("<script type=\"text/javascript\"> window.alert('" + msg.Replace("'", "\\'") + "')</script>"));
   }

This is the lengthy coding. either you directly access Session in javascript
see this

JavaScript

var Labeldet;
Labeldet = = <%=Session("LabelDetails")%>;

Thank you for your answer but your 2 links doesnt address my issue and they are not helping me. In first one basically says that beware of the session expiration. Since I indicated in my question that I have retrieved the value and can see it this means that session havent expired yet. for your second link I have no idea how you come up with msgbox to not display ok button? i didnt ask such a thing like that :) and seems like the link is broken.

Hi, I am not saying that you have no idea to come up with msgbox. My allegation is that maybe in your msgbox had triggers such an error…
Sorry for the broken link… The url is at :
