Folks, in an ASP.NET app is there a recommended and reliable way of passing some client-side data into the post so the server-side can get it? Here's the flow:
1. Some JavaScript rendered with the app makes a call in onload to get the ID of the device (which is actually an iPad ID). 2. JS puts the ID into an <asp:Hidden> control's value property. 3. On post, the server-side code reads the ID out of the control. This works in testing, but on the iPad the control's value is a blank string in step 3. I suspect there are DOM or control behaviour differences in the browsers. So I'm hoping there's some more reliable way I don't know about to pass values from JS in the page back to the server. *Greg K*
