Hello!

After Q1 release I found that PDFViewer became slow opening PDF files. I researched and found that the bottleneck is PdfFormatProvider().Import(). Also I found that it is slow espessaly for PDF files that produced by MS Word(I use Office 2013). Here is an example: http://www.fileswap.com/dl/aasX4Wy6QE/. Opening(with option ReadAllAtOnce) takes about 13 sec. Is there way to improve performance for similar files?
UPD: Link to sample pdf is changed

I submitted a 'suggestion' but I don't see it today. I tried to submit a ticket, but it won't let me because our maintentance program lapsed. Regardless of whether or not I am a currently subscribing customer, I should still be allowed to submit a bug report. I am using version 2012_2_0912.

When using Windows 7 with one of the larger font sizes, the map has two issues. The first is minor, but very noticeable. The image tiles are very fuzzy. It looks like they are being scaled/enlarged.

More importantly, Telerik.Windows.Controls.Map.Location.GetCoordinates is giving bad coordinates. I click on the map and use this function to get the geo coordinates. When I do this, the resulting coordinates are shifted a bit down and quite a bit to the right.

I am using RadCartesianChart to create a scatter chart showing both positive and negative values. Is there a way to display a line at 0 in each axis as is shown in this documentation for RadChart: http://www.telerik.com/help/wpf/radchart-features-negative-values.html

It appears to be controlled using the PlotAreaAxisVisibility but I can't find a way to gain access to the ChartArea when using a RadCartesianChart.

Any suggestions? 

Thanks,

Andy. 

Hi,

I am using v2013.1.220.45.

I have created a ScheduleView with databound Resources.
I am dragging data from a GridView to the ScheduleView. All is working, but when dropping, the new appointment in the "AppointmentCreating" event is not associated to the resource I have dropped.

How can I get the resource I have dropped on ?

Thanks.

Hello. I'm using RadCartesianChart to show some data in Stacked Bar Series. I want to have dynamic number of series and for that i use
RadCartesianChart.SeriesProvider. I want to bind legend to my chart but legend doesn't display at the window. Here is snippets of code that i use in XAML:

        <telerik1:RadCartesianChart x:Name="Chart"
                                    Grid.Row="1"
                                    Palette="Arctic">
            <telerik1:RadCartesianChart.HorizontalAxis>
                <telerik1:CategoricalAxis />
            </telerik1:RadCartesianChart.HorizontalAxis>
            <telerik1:RadCartesianChart.VerticalAxis>
                <telerik1:LinearAxis />
            </telerik1:RadCartesianChart.VerticalAxis>
            <telerik1:RadCartesianChart.Grid>
                <telerik1:CartesianChartGrid StripLinesVisibility="Y">
                    <telerik1:CartesianChartGrid.YStripeBrushes>
                        <SolidColorBrush Color="#F2F2F2" />
                        <SolidColorBrush Color="Transparent" />
                    </telerik1:CartesianChartGrid.YStripeBrushes>
                </telerik1:CartesianChartGrid>
            </telerik1:RadCartesianChart.Grid>

            <telerik1:RadCartesianChart.SeriesProvider>
                <telerik1:ChartSeriesProvider Source="{Binding DailyDatas}">
                    <telerik1:ChartSeriesProvider.SeriesDescriptors>

                        <telerik1:CategoricalSeriesDescriptor CategoryPath="HourName"
                                                              ItemsSourcePath="Data"
                                                              ValuePath="Value">
                            <telerik1:CategoricalSeriesDescriptor.Style>
                                <Style TargetType="telerik1:BarSeries">
                                    <Setter Property="CombineMode" Value="Stack" />
                                </Style>
                            </telerik1:CategoricalSeriesDescriptor.Style>
                        </telerik1:CategoricalSeriesDescriptor>

                    </telerik1:ChartSeriesProvider.SeriesDescriptors>
                </telerik1:ChartSeriesProvider>

            </telerik1:RadCartesianChart.SeriesProvider>
        </telerik1:RadCartesianChart>
        
        <telerik1:RadLegend Items="{Binding ElementName=Chart, Path=LegendItems}"/>

DailyDatas is an ObservableCollection of DailyData:

    public class HourInfo
    {
        public string HourName { get; set; }
        public double? Value { get; set; }
    }

    public class DailyData
    {
        public string RoleName { get; set; }
        public ObservableCollection<HourInfo> Data { get; set; }
    }

What am i doing wrong? Maybe there is another way to make dynamic number of stacked bar series?
Suggest me please asap! Thank you in advance!

Hello.
I am using the context menu in the GridView and under some circumstances displaying a Popup to the user.  When I do this I see focus being placed on the user control within the Popup but it immediately leaves.  The focus is being placed back onto a cell.  My attempts to intercept this have failed.  Is there some mechanism or pattern available to resolve this?

I am using the same pattern from within the ChildHierarchyTemplate the focus remains on the user control within the Popup.

Thank you

Paul

Hello,

I am trying to use Telerik's WPF GridView control in a MVVM application.  I have two general questions:

1) It seems that the XAML/WPF approach to MVVM requires the view to both a.) databind to the viewmodel, and b.) sink events from the viewmodel (that is, the view must respond to events from the view model).  Given that the Telerik WPF DataGrid obviously resides in the view, where does Telerik document the complete list of WPF DataGrid properties and methods?  Surely we can't be expected to infer the list of properties and methods from the samples?  Yet I cannot find what I normally think of as documentation.

2) In the stock MVVM definitions and explanations I find on the internet, it seems that the MVVM advocates claim there is a "clear separation" of concerns between the view, the viewmodel, and the model.  But in the stock MVVM implementations, I find that the view's XAML invariably contains column names in the grid declaration.  That seems to violate MVVM, no? In these implementations, the view seems to be overly concerned with the model.  Wouldn't it be best if the view only knew how to query the collection of column names from the viewmodel? Then you wouldn't have to modify the view (that is, the XAML) every time a user requested a new column.

Thanks.  I apologize in advance if these newbie-ish questions have been asked elsewhere; I queried the forums and could not find answers.
