Hi,
In my project, page1.aspx contains a button and a function in code behind. When clicking on the button, I''ve to pop up a window(page2.aspx) and when the pop up window is getting closed function in the page1.aspx.cs should be called. How can I do it? I tried javascript function to open the pop up window, but how will I call the function after return?

Thank you.

推荐答案

You have to write a javascript function in page1.aspx say 'parentFunction()',
in this function you have to call your code behind function.

Now in your pop up window page2.aspx before closing this window
    in javascript call page1.aspx function 'parentFunction()'
using window.opener.parentFunction()

尝试使用委托并相应地触发父页面的事件.

Try using delegates and accordingly fire the event of the parent page.
