By now you're probably used to reaching into the .NET Framework using Managed Extensions with your C++ code. But what do you do if you have legacy apps that use older versions of the compiler, or if you want to avoid some of the CLR requirements? Well, you can wrap Framework classes in a native way so you can use them in any C++/MFC app without /clr. Paul DiLascia shows you how.

The next version of Microsoft SQL Server, code-named "Yukon," represents quite a few steps forward in the evolution of XML integration. Yukon supports native storage of XML data using the XML data type, which makes it possible to run native queries on XML data using the emerging industry standard XQuery language. Data integrity of the XML data type can be enforced through schema validation and XML-based check constraints, and special indexes can be defined that help speed up queries. In addition, Yukon has the built-in ability to expose its data through Web services. This article discusses these and other XML features of Yukon.

In essence, I am creating Dynamic Checkboxlist controls and adding them to a Panel.  It works well when I do not have a Master Page configure to this webpage. Once I have a masterpage congifured.. I get a "Object Reference not set to instance of object" error on the Panel_Control.Controls.Add(Checkboxlistnew) line:

protected void Page_PreInit(object sender, EventArgs e)
    {
       
        XML OXML = new XML();
        
        alistChkBoxLabels = OXML.XMLTransform("C:\\Documents and Settings\..\\Config_new.xml", "config_options/check_box/applications/app/@name");
        int count = 1;
        alistCheckisFacility = new ArrayList();
        alIDTracker = new ArrayList();
        while (count <= alistChkBoxLabels.Count)
        {

            Checkboxlistnew = new CheckBoxList();
            Checkboxlistnew.ID = count.ToString();
            alIDTracker.Add(Checkboxlistnew.ID);
            Checkboxlistnew.Items.Add(new ListItem(alistChkBoxLabels[count - 1].ToString(), alistChkBoxLabels[count - 1].ToString()));

            String sAppName = alistChkBoxLabels[count - 1].ToString().Trim();

            
            alistCheckisFacility = OXML.XMLTransform("C:\\Documents and Settings\\Administrator\\My Documents\\Visual Studio 2005\\WebSites\\User_Trial\\Config_new

I have been using the following tutorial and had to convert the code to C# for my project, now i cant get the code to work, im getting red line under the word "in" in the UpdateRolesFromList,
i tried to add a datasource on page load for the checkboxlist like so RoleList.DataSource = PopulateRoleList(User.Identity.Name.ToString());

and gives me error saying cannot implictly convert type 'void' to 'object'

http://weblogs.asp.net/scottgu/pages/Recipe_3A00_-Implementing-Role_2D00_Based-Security-with-ASP.NET-2.0-using-Windows-Authentication-and-SQL-Server.aspx

What am i missing, that when i load the page or even do a search it never displays the checkbox list as it shows in the tutorial?

        protected void Page_Load(object sender, EventArgs e)
        {
            
        }

        public void PopulateRoleList(string userName)
        {
            RoleList.Items.Clear();
            string[] roleNames = null;
            string roleName = null;
            roleNames = Roles.GetAllRoles();
            foreach (string roleName_loopVariable in roleNames)
            {
                roleName = r

I have asp.net checkboxlist control that bounded to a data source so the number of items in the control are different from one to to another time.

I have this function:

     $('#<%=chkListGroups.ClientID %> input:checkbox:checked').siblings('label').text();

this function will return all texts for all selected items in the control as a one string.


 I'm looking for a way that when I check a check box from the ckeckboxlist control will return only last checked checkbox.

this code :

$('#<%=chkListGroups.ClientID %> input:checkbox:checked').last().siblings('label').text(); 

returns last checked item for example if I checked second will return
 second item then when I checked fifth item will return fifth item but 
if now when I check third item will return fifth item so it is always 
returning last item checked in the list and I'm looking to

Please advice me how to do this using jquery.

I have used a checkboxlist in association with PopupControlExtender. All the items are inside the update panel. I used the server side SelectedIndex changed event of checkbox list for another purpose.  But it cause full post back while checking the check box item. The update panel doent make any sense here.

            CheckBox active = ((CheckBox)Emp_Form.FindControl("cbActive"));

            CheckBoxList roles = (CheckBoxList)Emp_Form.FindControl("UsrRoles");

            foreach (ListItem role in roles.Items)
            {                
                // do stuff
            }
