Question

I have a listview that is loaded with a list of objects that contain an attribute called AssigneeView which holds the date that the entry was opened. The listview's ItemTemplate has a label named “lblHeader”. What I want to do is loop through the ListView.Items and check each element’s AssigneeView attribute, if it is null, I want to set the lblHeader.Text to be bold (indicating it is unread).

I want to create a method that takes an attribute from the Object in the Items list called ticketID and lookup whether or not the AssigneeView field is null for that field and return a bool. So it would look something like

ForEach item in listview.Items
   if(IsUnread(item.datamember.ticketID)) then
       item.lblHeader.MakeBold
   else
      item.lblHeader.MakeNotBold

I’m not 100% on how to dig into the telerik control to get what I need to do this. Any suggestions?

UPDATE:
here’s where I am at the moment:

using (var client = new QUTIService.QSVCClient())
            {
                var data = client.SearchTickets(this.myGuid, txtSearchString.Text, 100, chkSearchClosed.Checked).ToList();
                lsvResultTickets.DataSource = data;
                lsvResultTickets.DataBind();
                if (data.Count == 0)
                {
                    lblStatus.Text = "No tickets found.";
                }
                else
                {
                    foreach (var item in lsvResultTickets.Items)
                    {
                        var obj = item.DataItem as QT.FullTicket;
                        if (TicketIsUnread(obj.OriginalTicket.TicketID))
                        {
                            //???
                        }
                    }
                }
            }

Ok, it turns out that I just had to drill down one more level. I didn’t need to pull out another method to do the check for me. I handled this is in the item loaded event handler, here’s what I ended up with:

protected void ResultItem_DataBound(object sender, RadListViewItemEventArgs e)
    {        
        var dItem = e.Item as RadListViewDataItem;
        var dObj = dItem.DataItem as QT.FullTicket;
        //if no read date, mark as unread (bold)
        if (dObj.AssigneeView == null)
        {            
            var headerLabel = e.Item.FindControl("lblHeader") as Label;
            headerLabel.Style.Add("Font-Weight", "Bold");
            headerLabel.Style.Add("Color", "Orange");
        }
    }
