Hi,

in my application I use a RadChart component and there is something visible and I want to know if it's possible to remove it. Picture enclosed.

Thank's

I have a public property on one of my classes that is configurable by a PropertyGrid. It is a string property, but I want the user to be able to set it from a RadComboBox with values provided from an OpenAccess data model. I can't seem to put all the pieces together. The closest I got puts an odd value in the public property ("Telerik.Windows.Controls.RadComboBoxItem: City, State"). I've been banging my head against this for days and I'm tantalizingly close, but I'm just not seeing something.

How do I connect all the bits? The choices to the data source and the selected item to the public property? Here's my code without all my failed efforts taking up space.


Here's the property:

Here's the RadComboBox in the DataTemplate:

And here's the code-behind to (hopefully) populate the control:

Hi,

i was wondering if i can change the display style of an appointment in radscheduleview like shown in the attached screenshot? Is it
possible?
The default appointment style does only display the subject of an appointment in the week view for example. In my opinion, this is a waste of useful display space and my goal is to display additional information like the location, resources or category of an appointment.
I looked through the examples and API documentation but didn't found any hint or solution for this problem.

thanks in advance,

best regards

Hi telerik,

In my app I need to drag a row from at gridview onto a treeview.

When trying to drag, the cursor never changes to dragging-cursor. I'm a bit at a loss here.

I've tried to look at the example from "GridView Reorder Rows", but merging it over in my code has not produced the dragging cursor.


Can you confirm for me that it should be possible to drag from gridview to treeview?
Is it possible to construct a super simple example where it's done?

Internally in the treeview, I've got dragging working just fine -- the problem seems to be in allowing the dragging action to be initiated from gridview.

I'm still running Q1-release.

Thanks,

Anders, Denmark

Trying to understand how recent documents works I looked at your teams demo for RibbonView and i cannot understand where template are coming from

Seems that AddHandler for a FrameworkElementFactory won't work, event are never called ...

here follows the test code

foreach (var c in radGridViewTest.Columns)

            {

                        var factory = new FrameworkElementFactory(typeof(Button), "myButton");

                        factory.SetValue(CursorProperty, Cursors.Hand); // OK

                        factory.SetBinding(ContentProperty, new Binding(string.Format("[{0}]", 4))); //OK

                        c.CellTemplate= new DataTemplate();

                        

                        var mh = new RoutedEventHandler(onClick);

                        factory.AddHandler(Button.ClickEvent, mh,true); // won't work ...

                        c.CellTemplate.VisualTree = factory;

                        c.CellTemplate.Seal();
            }

I only get this some times (making it more annoying), but it seems like a bug in the OhlcSeriesRoundLayoutContext.SnapPointToGrid functionality. I need to be able to change the min/max of the vertical axis. Is there any way to turn off the snapping behaviour so it doesn't try to do it and thus doesn't break? Or is this something else doing it? I need to get this working rather soon.
