Hi I want to envoke the java script "window.open()" in the server side command button. Do you have any Idea how to do this? I want to create a download page with a Query String parameter from Data Time picker.

  this.btnDownload.OnClientClick="windows.open(download.aspx?FromDate=" + DatePicker.SelectedDate + ")"
   // Something like this

And I want to open a new page with Parameters every time the button was click. Server.redirect() is not suitable to my need. I believe Javascript Windows.Open() solves the issue except that I cannot get the property of the custom Control in ASP.NET server side.

Thank you
