Hello,

I am having an issue with reordering multiple selected items in a RadListBox. I am trying to select multiple items in a RadListBox, and drag them within the same RadListBox to reorder them. However, it doesn't always work. When I start to drag, sometimes I will be able to reorder the items (cursor indicator and drop visual indicator in the RadListBox show normally), and sometimes it won't. The drag visual always works normally, but it looks like AllowDrop is immediately false sometimes (not sure if that is what is actually happening, but it's the best way I can describe it). I have a test RadListBox for theme visual feedback and testing, and the behavior is happening there. Here is the code I am using:

And here is the code for ReorderableListItemStyle:

Is there something I am missing? I am using Telerik WPF R3 2020.

I'm trying to pass  a Telerik CrystalPalette to a Sub but I get an error "...is class type and can not be used as an expression".  Hints?

Hello All,

      After hours of digging through the forums and help pages and examples, I have NOT found a complete example of how to bind a RadRichTextBox to a viewmodel property.  I would like to see a complete example , all the XAML and all the code in the viewmodel to setup the binding.  I think it should be fairly easy , all I want to do is display some simple text from my database (it's a property in the viewmodel) in a RadRichTextBox...  I'm sure I'll have to use a TxtFormatProvider for the control, but I can't seem to find a complete example of how to do this to bind to a viewmodel property.  The viewmodel property gets set on the viewmodels object instantiation .  I have looked at the Developer Focused Examples and found the data binding example , but that's not a View-View Model example.  

Thanks in advance,

Since you folks don't provide any Telerik Label or TextBox controls, we have to use the Microsoft default controls which I then find out will NOT be themed via StyleManager per this link.  

If using the XML approach, how are we supposed to use themes without key support for two of the most fundamental and basic controls like Label and TextBox?

It makes the entire purpose of "Application level" themes useless without this basic support.

Am I missing something?

Rob.

It seems when I set a theme globally (using Implicit) and new Window I show doesn't have the theme applied to the actual Window ... like Title bar color, font, windows background ... they all seem to inherit default and not my assigned theme (i.e. GreenTheme).  The telerik controls on the Window do indeed use my assigned theme.

Does Telerik UI WPF suite provide an alternative or is this a bug?

Cheers, Rob.

Hello.

Help me with next problem, how i can rotate column header text of GridViewDataColumn on 90 degree?

I am create columns in programm code

column = new GridViewDataColumn
{
                   ColumnGroupName = args.ColumnDef.ColumnGroupName,

                    DataMemberBinding = new Binding(args.ColumnDef.Member)
                    {
                        Mode = BindingMode.TwoWay,
                        UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged
                    },
                    IsReadOnlyBinding = new Binding(args.ColumnDef.IsReadOnlyMember)
                    {
                        Converter = new NullToBooleanConverter {IsInverted = true}
                    },

                    Header = args.ColumnDef.Header,
                    HeaderTextWrapping = TextWrapping.Wrap,
                    IsVisible = true,
};

Also, how i can add borders to cells?

Hi,

I need to draw arrows on my ImageEditor.
These arrows must be drawn in multiple directions (N, NE, E, SE, S, SW, W, NW).
How can I accomplish that?

I implemented a Custom Shape tool and in my GetShapeGeometry() function I return the arrow Path figure.
But my shape seems to be crushed...

Any idea?

Thanks.
