Hello!

Im trying to create CustomGridView component by creating WPF CustomControl (control inherits telerik RadGridView). I realized that my custom control style is not loaded. I made simple example about this problem. Example should change my custom control background to blue but it does not.

my cs. file
public class MyCustomGridView : RadGridView  
{   
     static MyCustomGridView()
     {   
        DefaultStyleKeyProperty.OverrideMetadata(typeof(MyCustomGridView), new FrameworkPropertyMetadata(typeof(MyCustomGridView)));
     }  
  
     protected override void OnInitialized(EventArgs e)
     {         
        base.OnInitialized(e);       
     }    
 }

and here is my Generic.xaml in themes folder

<Style TargetType="{x:Type local:MyCustomGridView}">   

<Setter Property="Background" Value="Blue"></Setter>
  
 <Setter Property="Template">
         <Setter.Value>   
             
<ControlTemplate TargetType="{x:Type local:MyCustomGridView}">
                    <Border Background="{TemplateBinding Background}"    
                         BorderBrush="{TemplateBinding BorderBrush}"  
                           BorderThickness="{TemplateBinding BorderThickness}">
                    </Border>          
       
</ControlTemplate>      
       
</Setter.Value>      
   
</Setter>  </Style>

So basically this is classic start for WPF custom control, but in runtime this is not working. Am I missing something ?

Best regards

Hello,

I have problem with RadRibbonViewBackstage. My window shell contains two regions in separate rows. In First region I registered view containing RibbonView with RibbonViewBackstage. In second i defined statusbar view. When ribbonView's backstage is closed everything looks fine (First region and second shares window space). Problem appears when I open backstage. Backstage View is always taking whole window space and my status bar dissapears under. Is there any option to make Backstage same size as region in which i is defined so it will leave space for bottom status bar?

Thanks for your help :)

Hello,

I'm trying to use the PDF viewer to look at a specific page number in a pdf document. I try to set the document source, and then set the CurrentPageNumber property. The viewer will still only load the pdf on the first page. Is there a different way to jump to a specific page in the document?

I used the following:
PdfDocumentSource newDoc = new PdfDocumentSource(new Uri(@"C:\12345.pdf"));
pdfViewer.DocumentSource = newDoc;
pdfViewer.CurrentPageNumber = 5;

Hi,

I'm working with a RadCartesianChart to display Value / Time.
I'm using an DateTimeContinuousAxis as bottom axis. 
On this Axis I use a Major Step Unit in Days.

I display 2 series. One with value in days and one with value in hour.

The day serie is display with a simple LineSeries.

The hour serie MUST but be displayed in a RangeBarSeries to show min/max values.

In this case the Bar are to wide. My probleme is that RangeBarSerieModel generate a RadSize in function of the Axis Step size and not in function of the value covered by it.
In this case the Bar are to wide. 

For example 1 step == 1 day is represented by 28px then the bar have a width of 28px.

Is it possible to change the behavior to have a bar width = (Day/hour) * StepSize = Min(1,  1/24 * 28) ?

This way the width of the bar correspond to the time the value represent.

Thanks,

Hi. I'm adding a binding to the cell size and everything works correctly. 

xmlns:primitives="clr-namespace:Telerik.Windows.Controls.Diagrams.Primitives;assembly=Telerik.Windows.Controls.Diagrams"
 
<telerik:RadDiagram x:Name="diagram"      primitives:BackgroundGrid.CellSize="{Binding CellSize , Mode=TwoWay}"   />

 

But as soon as I connect the template, the binding disappears

1.   <telerik:RadDiagram x:Name="diagram" Template="{StaticResource RadDiagramTemplate}"  
2. Background="{Binding SelectedColorDiagram,   Mode=TwoWay, Converter={StaticResource customColorToBrushConverter}}"
3.primitives:BackgroundGrid.CellSize="{Binding CellSize , Mode=TwoWay}"   />

Other bindings, such as Background, work fine

 

I need a template to change ManipulationAdorner. Template code:

001.<ControlTemplate TargetType="{x:Type telerik:RadDiagram}" x:Key="RadDiagramTemplate">

Hi all

I am binding the 'IsSelectedProperty' to trigger actions when a RadDiagramShape is selected (Clicked).

I also need to handle when the Background of the Diagram is clicked.. I've tried the override '(Preview)OnMouseDown' functions, but these also get called when the shape is clicked. I want to distinguish the case where the background of the diagram is clicked only... not a shape. Any ideas what I should be using?

 

Thanks

I have found that when scrolling through up and down the years that I get incorrect values.  I have attached pictures of these values.  Obviously, when I select 1990 I expect to get years listed between 1990 and 2000 but I don't get that.

 

<telerik:RadDatePicker
    Grid.Row="4"
    Grid.Column="2"
    Margin="20,5,5,5"
    MaxHeight="60"
    IsEnabled="True"
    Background="{DynamicResource PrimaryBackgroundBrush}"
    Foreground="{DynamicResource PrimaryForegroundBrush}"
    SelectedDate="{Binding Patient.DOB, Mode=TwoWay}"
    DisplayDateStart="{Binding Patient.DOBDateStart}"
    DisplayDateEnd="{Binding Patient.DOBDateEnd}"
    SelectableDateStart="{Binding Patient.DOBDateStart}"
    SelectableDateEnd="{Binding Patient.DOBDateEnd}"
    DateTimeWatermarkContent="Enter Birth Date"
    ToolTip="{Binding [0].ErrorContent}">
</telerik:RadDatePicker>

I have a touch based application that uses a large font (Segoe UI 28) .  I need to force the Year/Decade Panels to display correctly.  How do I prevent the host panel from collapsing when I pick a year (it goes from wide accommodating the entire calendar down to listing only the Years) and I need to guarantee it doesn't crowd the years into a very small place?
