I dad a need to update all checkboxes on client side in a grid. Found a great article posted here by Cinnie Patel. I just added a slight mod to make it function on multiple grids on a page. In a nutshell the jQuery code is something like:

function SelectAll(CheckBoxControl,GridName)
{
   var newState;
   if (CheckBoxControl.checked == true)
   {
      newState = true;
   }
   else
   {
      newState = false;
   }
   var i;
   for (i=0; i < document.forms[0].elements.length; i++) 
   { 
      if ((document.forms[0].elements[i].type == 'checkbox') 
           && (document.forms[0].elements[i].name.indexOf(GridName) > -1))
      {
         document.forms[0].elements[i].checked = newState;
      }
   }
}

and then you place the code to call this on the header item of a grid (assuming you are using checkboxes in the header as well to select all/select none) like this:

<input id="SelectAllCheckboxes" onclick="SelectAll(this,'##NAME OF YOUR GRID GOES HERE##')" type="checkbox" />

Hope this helps someone and kudos to original poster.

I came across need the other day where I had to scrape a page. The issue was that if you are not logged in then you get different content to if you were logged in. It was a relatively easy solution but I came across some code that really stood out at stackoverflow.

The bulk of it a nice simple class to encapsulate the cookies and authentication credentials in a class as follows:

public class CookieAwareWebClient : WebClient
{
public CookieAwareWebClient()
{
CookieContainer = new CookieContainer();
}
public CookieContainer CookieContainer { get; private set; }

protected override WebRequest GetWebRequest(Uri address)
{
var request = (HttpWebRequest)base.GetWebRequest(address);
request.CookieContainer = CookieContainer;
return request;
}
}

Thus once you provide login details you can then easily call on the WebClient method as illustrated in sample code (also from the stackoverflow site):

using (var client = new CookieAwareWebClient())
{
var values = new NameValueCollection
{
{ "username", "john" },
{ "password", "secret" },
};
client.UploadValues("http://domain.loc/logon.aspx", values);

// If the previous call succeeded we now have a valid authentication cookie
// so we could download the protected page
string result = client.DownloadString(“http://domain.loc/testpage.aspx”);
}

Again this is not my code – I just liked it’s elegance in solving a simple problem.
