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;

RangeBarSeries, Proportional size in function of the area instead of the steps ?

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,

Chart

Primitives and template for RadDiagram

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:

Click on background

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

YearViewPanel displays wrong values

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"

PreserveSpaceForCollapsedChildren

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?

Question about ClassDiagram example

Hi,

The ClassDiagram example defines the class shape inside <style> definition. I need now dynamically access one TextBlock inside the definition as I need to set the text according to user input. I'm having hard time to do this as following does not work:

private void NewClass_Click(object sender, Telerik.Windows.RadRoutedEventArgs e)

{

ClassShape newClass= new ClassShape() { Content = "Class1", Position = new Point(300, 120) };

//newClass.ApplyTemplate();

var textBlock = newClass.FindName("TypeName") as TextBlock;

newClass.Loaded += this.OnNewClassLoaded;

this.diagram.Items.Add(newClass);

}

This is absolutely driving me crazy, so any help would be much appreciated.

The definition of ClassShape is something like:

<Window.Resources>

<Style TargetType="local:ClassShape">

<Setter Property="IsCollapsible" Value="True" />

<Setter Property="IsResizingEnabled" Value="False" />

<Setter Property="MinHeight" Value="100" />

<Setter Property="Padding" Value="15 5" />

[Solved] Force filtering to refresh when values in existing rows are updated

I have filtering enabled in my RadGridView column. When an existing row has it's cell value updated for the filtered column, the row should be excluded if it's outside of the filter parameters - however, this is not the case. I have to manually go back and adjust the filter for the row to be excluded.

How can I ensure that all current data in the grid is correctly filtered, even when cells are updated after the row is added?
