Hello,
I am opening a popup [i-frame] on button click in the Parent page. After i have done the operations in the popup page i am setting the values in parent page from the popup page. I can access the elements of the parent page and i am setting the values in the elements. however post back occurs and my values are lost.

this is the code that i am using in the child page or the pop up page which is inside a iframe.

$('input[id*="MyId"]:first', window.parent.document).val($('#<%= MyValue.ClientId%>').val());
$('input[id*="txtDesc"]:first', window.parent.document).val('hello');

any suggestions how can i keep the values ??

Try window.frameElement.ownerDocument instead of window.parent.document...

window.parent.document is working fine. i checked just now that it is also setting the value in the corresponding fields. however post back is happening and i am loosing the values then. any suggestions. Can't use querystring , session , viewstate etc.

Stop post-back by return(false); or use AJAX...

even if i am returning false or setting e.preventDefault() from child page, post back happens

You maybe doing it at the wrong place...
Please show the relevant code for the click...

This is the function in the childpage inside document.ready

if ($('#<%= hiddSuccess.ClientId%>').val() == "1") {

$('input[id*="hiddId"]:first', window.parent.document).val($('#<%= hiddValue.ClientId%>').val());
$('input[id*="txtSelectOne"]:first', window.parent.document).val('ASUS_ME102A-1A035A : ASUS_ME102A-1A035A');
window.parent.closeIframe();
return false;
}

This is inside pageload of parent page

If Not IsPostBack Then
If (Not PrivilegeHelper.licenseLoginCheck(Session, Response, Request, "ABCD", True)) Then
Exit Sub
End If
Dim trans As Translator = New Translator(Session("UserLNG").ToString())
Translate(trans)
BindGrid(first, second)
End If

If you are updating textboxes etc and that data is being lost on postback then the problem is probably that you are always initialising the textbox values even on postback because you don't have "if (!Page.IsPostback)" around your init code in the page_load, or you are re-initialising the values somewhere else. As you haven't posted the relevant code it's hard to say for sure.

nop. i have used IsNotPostback. and i have not reinitialized the values. coz of post back the values of both fields that i am populating from the child page becomes blank.

this is what is happening inside the pageLoad

If Not IsPostBack Then
If (Not PrivilegeHelper.licenseLoginCheck(Session, Response, Request, "ABCD", True)) Then
Exit Sub
End If
Dim trans As Translator = New Translator(Session("UserLNG").ToString())
Translate(trans)
BindGrid(first,second)
End If

So, when you close the iframe, the parent page reloads?
