How do i get the values of label on my iframe and pass it to the default page?

What I have tried:

Page load of default page:

C#

protected void Page_Load(object sender, EventArgs e)
{
   if (Session["name"] != null) 
   {
      lblName.Text = Session["name"].ToString(); // I have also tried to do this without the if statement.
   }
}

Page load of 2nd page or my iframe src:

C#

protected void Page_Load(object sender, EventArgs e)
{
   lblName.Text = name.Value;
   Session["name"] = lblName.Text;
}

You already asked this before. Where exactly are you stuck? You only set the Session value in the 2nd page so if it loads after Default, default can't get to it. This should be very easy to understand so please try to explain where you are stuck.

I need to get the value of labels of the 2nd page so that on load of the default page the values should be displayed. If session is not possible for this, do you know any other way on how to do this??

1. As mentioned last week, reply to the comment so that we get notified. Don't add a new comment to your own question.
2. Explain exactly what is happening. Is default the first page loaded or second page?

Member 11525563 22-Feb-16 11:23am

the default page is the first page loaded.

ZurdoDev 22-Feb-16 11:28am

Then how can it get values from a page that hasn't loaded yet?

Member 11525563 22-Feb-16 13:05pm

the 2nd page is loaded on the iframe of the default page.

ZurdoDev 22-Feb-16 13:21pm

OK. What is your question exactly. You know that to get a value from the session you have to set it first. So, what exactly do you want from us?

Member 11525563 22-Feb-16 13:23pm

How can i display the value of label on 2nd page to the label of my default page?

ZurdoDev 22-Feb-16 13:24pm

Depends. When do you want that to happen? When a button is clicked?

Member 11525563 22-Feb-16 13:30pm

on page load of default page

ZurdoDev 22-Feb-16 13:34pm

But you can't because it does not exist yet, right?

How about whatever logic you are using to set it in the 2nd page, do the same thing in the default page.

Member 11525563 22-Feb-16 13:44pm

that's why i asked earlier if there's another way to do it beside session

ZurdoDev 22-Feb-16 13:45pm

Sure. How is it getting set in the 2nd page? Do the same thing in default.

string body = Regex.Replace(item.HTMLBody.ToString(), @"<[^>]*>", String.Empty);

Match addressMatch = Regex.Match(body, @"[^\d]\d+([a-zA-Z0-9\-\s]+)", RegexOptions.IgnoreCase);

address.Text = "Address: " + addressMatch.Value.ToString();

Probably best to put javascript in your 2nd page and use jquery's document.ready function. In there reference the control on default.aspx with something like this: window.parent.document.getElementById('lblName').Value=whatever;

Member 11525563 22-Feb-16 14:03pm

is the "window.parent.document.getElementById('lblName').Value" is the label of my default page?

ZurdoDev 22-Feb-16 14:15pm

Yes.

Member 11525563 22-Feb-16 14:25pm

Thanks so much.

ZurdoDev 22-Feb-16 14:26pm

Sure.

As discussed in comments, because of the order of events that you have it sounds like you should use the jquery's document.ready event in the 2nd page and have it reference the label on the default page.

For example:

JavaScript

$(document).ready(function () {
 window.parent.document.getElementById('lblName').Value= document.getElementById("lblName").Value;
});
