I am attempting to persist a gridview with custom filteringer.  I am using the GridViewCustomPropertyProvider class in your example and see that I am hitting the ProvideValue method but in the if condition for FilterDescriptors I have no ColumnFilterDescriptor which IsActive is true.  If I remove my custom filter I do find the IsActive column.

 

My custom filter does function get applied to the grid as I am implementing the IFIlteringControl.  I also do have an IsActive DependencyProperty on my class.  In fact, the basis for my custom control was from your example code as well.

Is there some issue with using the PersistanceManagers Save method when the filter is a custom filter or am I missing something?

Thanks

I am trying to figure out how to get the Treeview to ignore the SelectedUnfocused VisualState. I am also trying to use the Windows8Theme with my project as well. When ever I try to edit the template, I always get the default colors. I would also like to be able to have the ability to change the theme at any given time. Is there an option I am missing that can enable and disable that function?

I am sorry if this is a duplicate, I did look to see if anyone else was having this exact issue. :)

Thanks
ZS

Hi all,

I am currently using the RadGridView with the IDataErroInfo interface to perform validation with my View Model.

This is currently working as expected but I would like to change the cell validation style, in particular the tooltip and the how the red border around the cell works.

I would like to continue to use the IDataErrorInfo interface for the validation but just change the error template being used (rather then to start building cell template selectors for example)

Thanks in advance!

I have a HierarchyChildTemplate which contains a TabControl.  The model driving content for to the HierachyChildTemplate has collections to drive the content in each TabControl.  The issue is when there is a change to a collection driving one of the tabs the tab fires the SelectionChanged event.  One of these tab items holds the the FlowDocumentReader control so the SelectionChanged cannot be bubbled up and caught by the TabControl.  The update to the data is reflected correctly by the way.

I replaced the Microsoft TabControl with the RadTabControl in hopes that your control will have special handling for this, like the additional support you provide with the IsContentPreserved property.  However, I see no default handling for this and find nothing within the RadTabControl I can use to deal with this.

How can I keep the tab fro changing to index 0 every time there is a change?

Thanks

I do not see a way of zooming using touch without adding code on my part.  I hope that full touch manipulations would be added in a future release.  In the mean time, any examples showing the easiest way in your opinion to add a simple two finger zoom would be nice.

An example of how to bind DocumentSource to a string, would also be nice.  I see a reference to a PdfDocumentSourceConverter in the docs, but I see no examples of how to use it, nor any clues as to what xlmns namespace we have to expose to see it. 

I would also like to understand what if anything we need to do to clean up when we switch DocumentSources. 

The documentation on this control is pretty sparse. 

Thanks
Paul

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!
