推荐答案

好吧，我得到了解决方案。

我做的很简单，我用过javascript从IFRAME中的控件读取值，将它们保存在隐藏文件中，然后从代码隐藏文件中获取，我从隐藏字段中获取它们并将它们设置为相对位置。





这是我用过的东西







Javascript：

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; 

之后，我从代码隐藏文件中做到了这一点。 （C＃）

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

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

现在，我使用了这个数组的值并完成了我的任务..

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