DragDrop Hosted in Windows Forms

Hello,

I'm having trouble with the RadDragAndDropManager when the UserControl that is using it is being hosted inside of a Windows Form. I made a quick example.

    
            <UserControl x:Class="DragAndDropTest.simple" 
        
                xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
        
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
        
                xmlns:dragDrop="clr-namespace:Telerik.Windows.Controls.DragDrop;assembly=Telerik.Windows.Controls"> 
        
                <UserControl.Resources> 
        
                    <Style TargetType="StackPanel"> 
        
                        <Setter Property="dragDrop:RadDragAndDropManager.AllowDrop" Value="True" /> 
        
                    </Style> 
        
                    <Style TargetType="Label"> 
        
                        <Setter Property="dragDrop:RadDragAndDropManager.AllowDrag" Value="True" /> 
        
                    </Style> 
        
                </UserControl.Resources> 
        
                <Grid> 
        
                    <Grid.ColumnDefinitions> 
        
                        <ColumnDefinition /> 
        
                        <ColumnDefinition /> 
        
                    </Grid.ColumnDefinitions> 
        
                    <StackPanel

                } 
        
            }

seems to work fine inside of a wpf Window but not a Form.
Any ideas on what I'm doing wrong?

Thanks much,

How to change the chart item ControlTemplate?

Hello,

in the ChartControl-Help I found this hint to increase charting performace:

Simplify the chart item ControlTemplate - e.g. the Line item template contains by default an item label and a point mark visual. The point mark visual can be removed (as they are relatively insignificant when rendering thousands of records). With lots of points the sheer number of UI elements simply bogs the system down as discussed above). So if you cannot reduce the data points, you will need to simplify the chart item ControlTemplate.

Can anybody give me an example how to do this?

SelectedItem Binding OneWayToSource tries to get the property value

Hi,

I have a combobox in my application that has this binding on the SelectedItem

SelectedItem="{Binding Path=Food, Mode=OneWayToSource}">

The back end property is define as follows

public Food Food

{

get { return _food; }

set { _food = value; }

}

My problem is that the above binding will try to get the property, this is not the expected behavior for this type of binding.
Can you suggest a work around you come up with fix ?

Thank you,

ComboBox

Quick Start Framework for WPF

Do you plan on publishing something like this that you did for WinForms? Or at least release all of the code used in the demos? I see others are asking the same thing too.

Thanks!
