I've noticed that when I add drag and drop to a grid the column sizing no loger works.

I have implemented the drag/drop events..

        private void OnDropQuery(object sender, DragDropQueryEventArgs e)
        {

            Type sourceType = e.Options.Source.GetType();
            if (sourceType == typeof(GridViewHeaderCell))
            {
                return;
            }
        .
        .
        .

and
        #region dragQuery
        protected virtual void OnDragQuery(object sender, DragDropQueryEventArgs e)
        {
            if (sourceType == typeof(GridViewHeaderCell))
            {
                e.QueryResult = true;
            }
        .
        .
        .

How should the drag and drop respond to the GridViewHeader?

Hi,
I have typed the following text in Google-translator, so it goes faster, so please excuse any errors.
I have the following problem with the WPF RadWindows:
Whenever it opens, is thrown a System.ArgumentException. Whether it's own window, or create the controls of their choice.
The windows are always at the upper corner of the screen. If I want to move the window, thrown the exception.
Here is a screenshot of a window of RadShedule: http://img1.bildupload.com/4ed9dbb35ad45e65eb4bc6814fa455cf.jpg and as attachment.

I searched for this error (google and Telerik) and have found several entries. Unfortunately, none has been solved so far.
I've tried the following workarounds:
1. Catch the ecxeption in app_DispatcherUnhandledException does work, but the application also crashes after short time (when moving), so no solution
2. refer to this thread: http://www.telerik.com/community/forums/silverlight/gridview/radgridview-exception-onclose-of-radwindow.aspx: still no solution
3. i found this: http://www.telerik.com/community/forums/silverlight/window/exception-value-does-not-fall-within-the-expected-range-when-displaying-nested-rad-windows.aspx, but there is also no solution, only a reference at the HACKS class (but this is still private, perhaps in the internal user) you.

I'm desperate, I can indeed use for my own window, the standard Window class, but all of the windows, for example RadShedule are RadWindows.
The error also appears in your wpf example application. (detailed see screenshots):

But...,
in Silverlight the moving, resizing and closing and reopening of the window works with no problems: http://img1.bildupload.com/60332521dc5deec8783c99ae08dc5f84.jpg

I would like to thank you very much if you could deal with the problem, since all other contributions were offered no further assistance or solutions. I can send you all important project data, unless you can reproduce the problem.
Can it possibly be constellation problem with my system. If you suspect this, I send you also necessary system parameters (os: Vista Ultimate 64-bit video card: NVIDIA 9800 SLI (2 units) and so on)

Many many thanks in advance.

Hi

Just thought I'd make a suggestion for a new WPF control.

I not sure if there's a name for it already but basically its kind of a spinning progress indicator, to show the user that something is happening but it doesn't actually show progress. Like if you were loading data to the UI.

The best example I can think of is in Firefox when its loading a website. In the tab, there's a small circle of circles and each circle flashes around the main circle, whilst the page is being loaded.

I've already created something similar but it took me ages to get the animation (see attached).

Just being able to drop the control and set a few animation properties would have saved me several days work.

I think it would be popular.

Hi,

I have a carousel on a WPF page and it seems the Height of the CarouselItem does not allow me to set it above about 300 pixels.  See my attached screen shot A and B. 

I am setting the CarouselItem template using the following XAML:
And set the main border inside the control template to this:

It still clips the content to what appears to be somewhere between 250 and 300 pixels. 

How can I make the content template height larger to fit my content?

Thanks,

Hello!

Hi, 
we updated to Telerik 2010 Q1 Beta, and now we can drag the floating window outside of the main window, but we no longer can drag and drop from one floating window into another or into the main window.
What should we do to make the drag and drop work between the windows.
Thanks
Nick

Hi,

How do I set the DateFormat in the RadDatePicker.

For example, I want to show the date 9/7/09 as July 9, 2009 in the textbox. Any help would be appreciated.

Thanks,
