Modal Dialog read params server side

Question

I have an applicationPage who is open by Modal Dialog. I would like to read this params server side in the application page . I don't use the URL for passing parameter, i use the options.args

Is it possible??

sample code :

Javascript :

var options = {
  url: '/_layouts/MyApplicationPage.aspx',
  title: 'Title',  
  autoSize: true,   
  args: { arg1: 'arg 1', arg2: 123, arg3 : 'other arg'} // My params
};
SP.UI.ModalDialog.showModalDialog(options);

Server side of MyApplicationPage.aspx

protected void Page_Load(object sender, EventArgs e){   
  // how to read arg1, arg2, arg3 ??

Answer 1

You probably won't be able to get the args in code-behind when you specify them within the options object. When working with the options object in Modal Dialog the args will be saved on client side only. Thus the server cannot get them.

To get these args you should modify your url like this:

var options = {
  url: '/_layouts/MyApplicationPage.aspx' + '?arg1=arg%201&arg2=123&arg3=other%20arg',
  title: 'Title',  
  autoSize: true,   
  args: { arg1: 'arg 1', arg2: 123, arg3 : 'other arg'}
};

This way you can get them with Request.Form["arg1"] As you can see, I did escape the arguments.
