How to pass values from an asp.net child page to the parent page

I have two web pages, Page1 and Page2, which can both open the same child popup page.

If the parent page is Page1 I want certain input from the Child page to returned to the parent page and if the parent page is Page2 I want other information to be returned.

I do identify who is the parent page and how do I return the input to it and have it show in the proper text box or DroDownList?

I tried using Request.UrlReferrer putting results in a string variable and I got an error 'object not set to an instance'.

As both the pages can be parent , write the a javascript function that works as receiver on both the page and write code in it as per your requirement.

e.g.

javascript on Parent page:

SetDataFromPopup(data)
{
    document.getElementById('TextBox1ClientId').value = data;
}

On popup write the following line 

window.opener.SetDataFromPopup(data);

this should be called on the event where you want to pass the data e.g. suppose you have a button on client click of it you want to pass the data , the code should look like:

<input id="btnSave" type="submit" onclick="window.opener.SetDataFromPopup(data);" >Save</input>
