I have a ListBox with shapes that I am dragging onto a RadDiagram.  The snapping works when an item is dropped on the diagram, thanks to this post --> http://www.telerik.com/forums/snap-to-grid-when-dropping-new-item.

However, I would also like the same functionality to work when previewing this drop ( add the alignment lines and preview where the shape will be snapped to )

Is there any way implement this snap preview? Any feedback would be helpful.

Hi all,
i am working with RadPivotGrid with an EntityFramework Datasource

i would like to add a datasource made like that:
this.queryableDataProvider = new QueryableDataProvider()
{
      Source = DBContext.PERSON.Include(e => e.TASKS)                                         
};

when i start the program in the RadPivotGrid and in the FieldList i only see PEERSON and i am unable to see any further level of my DataSource (everything that is in the "include" linq query.

all the EDM Model is tested in many years and works great with all the telerik controls but i am unable to use RadPivotGrid

am i missing some points?

Thanks
Andrea

hi my friend

how I can change with of radcombobox depend on it's selection value  with nice animation

like changing in your wpf demo search textbox when we start change it's width resizable

I am using RadRichTextBox to display documents text and image. I am using telerik wpf controls 2015 Q3 Sp1.  The issue is that when I paste an image on to the control and use it to generate a document the image quality is decreased. Any help would be appreciated. I have tried this with .png and.jpeg images.

I am using PDFFormatProvider of terelik to convert the RadDocument to pdf.

Thanks,

Hello,

I have a problem when using diagram in ribbonview,

I want to set the 'New','Open','Save' button of the firstlook demo to the RadRibbonBackstage, the code is:

<telerik:RadRibbonView.ApplicationButtonContent>
                <TextBlock Text="Begin" Margin="10 2" />
</telerik:RadRibbonView.ApplicationButtonContent>

<telerik:RadRibbonView.Backstage>
                <telerik:RadRibbonBackstage>
                    <telerik:RadRibbonBackstageItem Header="New" IsSelectable="False" Icon="pack://application:,,,/FOSS.Common;component/Images/new32.png" Command="telerik:DiagramCommands.Clear"
CommandTarget="{Binding ElementName=diagram}"/>
                    <telerik:RadRibbonBackstageItem Header="Open" IsSelectable="False" Icon="pack://application:,,,/FOSS.Common;component/Images/open32.png" Command="telerik:DiagramCommands.Open" 
CommandTarget="{Binding ElementName=root}"/>
                    <telerik:RadRibbonBackstageItem Header="Save" IsSelectable="False" Icon="pack://application:,,,/FOSS.Common;component/Images/save32.png" Command="telerik:DiagramCommands.Save"
