Hello!
I use the ASP.NET telerik controls and love them...

However in a new development project at my company, it has been decided to use WPF as both a desktop solution (great! Meant for that!) but also as a "web product". It will be accessible via a public site but also sold for intranet use. It is a HUGE RMS system for the fire industry. Are there any case studies using WPF application run in this way? Over the internet via browser? What are the limitations? I have not been able to find ANY information really on using WPF as a web application.

I know ASP.NET is used for web apps, but in this case, management wants to use WPF. Mainly for the single code base (Desktop/web). However, it does not appear to have been meant for web deployment based on the literature... THoughts?

Thanks
Harold

I installed RadControls for WPF Q1 2009.  I can't get any tools to post to the Toolbox.  I select RadCarouselPanel on the WPF tab, click OK, but nothing gets added.  I've added Telerik.Windows.Controls as a reference.
Added 3/15.  VS2008SP1 now restarts anytime I try to add a tool.  This seems to be a VS problem.  I've tried "devenv /reset and /safemode w/o success.  I see where this was a problem before SP1.  Any help appreciated; it makes it hard to use RadControls!
Added 3/17.  Toolbox now working see - Can't add items to toolbox in Visual Studio 2008

Hi Telerik,

In Q1 2009 when I drop down the list for the StyleManager.Theme in the IDE (Blend AND VS2008) a strange gradiant (purple to blue with a black line under) list appears for the list of themes.

I can get you a screenshot if you need it.

I download and installed the latest 2009 Q1 release and the included demo examples contains a lot of errors:

my laptop is setup with:
VS2008, .Net 3.5 SP1, XP2Pro

Any solution? Tnx.

Is there currently a way to label the series on a pie chart from a data field ?

Hi,

I use VS and Blend to build a wpf application. When using Blend all of a sudden I get the following error message
The name <telerik control tab/grid> does not exist in the namespace "http://schemas.telerik.com/2008/xaml/presentation"'

I have tried Clean, re-referencing, re-build but to no avail. This error is only in design time in Blend.

any advise?

Hi,

Executing following code recieved strange NullReferenceException:

        private void IterateRows(IList<Record> records)
        {
            foreach (Record record in records)
            {

                if (record is ExpandableDataRecord)
                {
                    ExpandableDataRecord expandableRecord = (ExpandableDataRecord)record;
                    expandableRecord.IsExpanded = true;

                    IterateRows(expandableRecord.ChildRecordManagers[0].Records);
                }
            }
        }

        private void Expand_Click(object sender, RoutedEventArgs e)
        {
            this.IterateRows(this.radGridView1.Records);
        }


System.NullReferenceException was unhandled

Any thoughts?
Just to mention that I don't have r:\WPF_Scrum\WPF_Team\Sources\Development\WPF\GridView\GridView\GridViewItemsControl.cs on my computer ;)

Hello,

i am working with the radtreeview, i want that the default styling on the mouseover should be removed.
Please suggest with code snippet.
Thanks and regards

If the height of the RadChart is not specified in xaml the radchart starts to grow vetically(a lot)  in the designer mode.
this slows down the system. But when the project is run all shows normally.
In the Q1 2009 is going to be ok???
