Transfer Date from one page to another in aspx

[imtmub]

I have two page one is parent and child. Parent page has text field and command button. The Link button open a child page as a popup. Child page as Text box and Button. when i click the button it will transfer child textbox data parent page text box. this is working fine when i use normal page(Not using master page on it).
Parent page aspx:

 
<asp:TextBox ID="TextBox1" runat="server" AutoPostBack="True"></asp:TextBox>
<a href="#" onclick="OpenNewWindow()">Lookup</a>
 
 
function OpenNewWindow() 
{
window.open('Child.aspx','MyPopUp','width=500,height=700,scrollbars=1,resizable=1');
}
 

Child.aspx:

 
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<input id="Button2" onclick="Transfer()" type="button" value="Select" style="width: 65px" />
 
function Transfer() 
{
window.opener.form1.TextBox1.value = document.getElementById("TextBox1").value; 
window.close(); 
}
 

This code is working fine. Child page transfer the data parent.

But i when i use master page in parent page. I can open child page using pop up. The child page not transfering the data to parent page with same code. i dont know whats went wrong. Can i anybody what i have to change. I am not getting any error and the data is not transfering

Thanks in advance

Hi imtmub,

If you check the source html generated by your code you'll probably find that the ID of TextBox1 has been changed to something like ctl00_Content1_ TextBox1.

To get the actual ID you need to pass the ClientID property of your TextBox control to your popup window and use that to pass the value back. Here's an example:

Parent:

window.open('Child.aspx?txt=<%=TextBox1.ClientID%>','MyPopUp','width=500,height=700,scrollbars=1,resizable=1');

Child:

window.opener.form1.TextBox1.value = document.getElementById('" & Request.Querystring("txt") & "').value; 

Let me know how you get on,

Dr B

PS You posted this in the ASP Forum which is for Classic ASP only - I've moved it for you but please remember to post all future ASP.NET questions in the .NET Forum. Thanks.

First of all I have to say thanks for ur response.
When i check the Source html genreted by my code My Textbox1 id change to "ctl00_ContentP laceHolder1_Tex tBox1"

Then I have modified my java function according to your suggestion. Still i am facing the same problem. The Textbox is not transfering data to parent page textbox. Can u see anyother info i need to change?

Thanks

window.open('ChildMain.aspx?txt=<%=TextBox1.ClientID%>','MyPopUp','width=500,height=700,scrollbars=1,resizable=1');
}
 

ChildMain:

I can't see anything obvious - can you check the value that is passed in the querystring and compare it the actual ID from your mark-up. Are they the same?
