Closing Iframe from inside with code behind

well, I got the solution.
what I did is so much simple, I used javascript to read values from control inside the IFRAME, saved them in a hidden filed, then from code behind file, I get them from hidden field and set them to their relative place.
 

this is what I used
 

 
Javascript:

var IFrame = document.getElementById("IFrameIDHere");
var Values = "";
 
Values += IFrame.contentDocument.getElementById("control_1").value + ","; 
Values += IFrame.contentDocument.getElementById("control_2").value + ","; 
Values += IFrame.contentDocument.getElementById("control_3").value + ","; 
.
.
.
.
Values += IFrame.contentDocument.getElementById("control_n").value + ","; 
 
document.getElementById("HiddenFieldID").value = Value; 

 
after that, I did this from code behind file. (C#)
 

string[] Values = HiddenFieldID.Text.ToString().Split(',');

 
now, I used values from this array and did my task..
