I'm calculating the screen size of the browser and storing passing it to the server and i'm dynamically creating controls on the page OnInit() based on the sizes. But OnInit() on the USERCONTROL is getting fired before javascript function fires to calculate the screen size.... i need the browser size on Onit no matter what for my task .... Any ideas? please help mail to [email protected]

Hi there,

You can't do it like this. When you request a page, it runs at the server first. The generated HTML is then sent to the browser when you can run some JavaScript. This means that for a single request, OnInit always fires before any client side JavaScript.

You could use a two-step approach:

1. Render a normal page just once, let JavaScript collect the screen resolution and submit to the server.
2. Store the resolution in cookies or session variables or elsewhere and use that information for subsequent pages.

This way, you overcome your problem as you collect the info just once in a separate request once at the start of a user's visit.

Cheers,

Imar
