Hi Team,

I'm new to telerick controls and using image editor control. i would like to know how to change theme for this control like i want to configure visual studio 2013 dark theme;

Give some sample code or explain the steps.

Regards

Hema

With a basic RadPropertyGrid, if I set the Item to an object with a System.Windows.Media.Color property, when I pick a color in the editor, it will properly call the property setter and update Test1's Color value.

public class Test1
{
    public System.Windows.Media.Color Color { get; set; }
}

If I use the following Test2 class instead, changing the color in the property grid will not call the property setter and the value in the box will not get updated.

public class Test2 : INotifyPropertyChanged
{
    public System.Windows.Media.Color Color { get; set; }
    public event PropertyChangedEventHandler PropertyChanged;
}

Hi,

We're using version 2015.2.728.45 of Telerik UI for WPF and we are encountering an issue with the hyperlink dialog. Here is the related xaml code used in the ribbon of the application:

<telerik:RadRibbonButton LargeImage="pack://application:,,,/Telerik.Windows.Controls.RichTextBoxUI;component/Images/MSOffice/32/inserthyperlink.png" telerik:RadRichTextBoxRibbonUI.RichTextCommand="{Binding Path=ShowInsertHyperlinkDialogCommand}" telerik:ScreenTip.Description="Create a link to a Web page, a picture or an e-mail address." telerik:ScreenTip.Title="Insert Hyperlink" Size="Large" Text="Hyperlink" />

Each time we insert/update an hyperlink using the "Insert Hyperlink" modal dialog, we get an extra "http://" prefix added to the beginning of the address. What should we do to avoid this behaviour?

Thanks for your help,

Sébastien

Hi,

At the moment, upon loading my usercontrol, I programatically load all my calendar events. I export my outlook calendar folder then import it into the schedule view. I'm wondering what is the best approach to integrate with outlook? I created methods to trigger OnAppointmentDelete and OnAppointmentCreate, such that it'll update outlook. But is this the ideal solution? 

        private void LoadOutlook()
        {
            try
            {
                var outlook = new ApplicationClass();
                var OutlookNS = outlook.GetNamespace("MAPI");

                MAPIFolder f = OutlookNS.GetDefaultFolder(OlDefaultFolders.olFolderCalendar);

                CalendarSharing cs = f.GetCalendarExporter();
                cs.CalendarDetail = OlCalendarDetail.olFullDetails;
                cs.StartDate = new DateTime(2011, 11, 1);
                cs.EndDate = new DateTime(2018, 12, 31);
                var tempPath = Path.GetTempPath();
                var tempCalendar = tempPath + "cal.ics";
                cs.SaveAsICal(tempCalendar);
                using (TextReader txtReader = new StreamReader(tempCalendar))
                {
                    this.Import(txtReader);
                }
            }
            catch
            {
                
            }
        }

So I have a working save/load for my RadPivotGrid with LocalDataProvider, but had performance concerns so added set of wrappers and functionality for QueryableDataProvider.

My wrappers and set with properties (get; set;) of types int, double, string, bool?, string, MyEnum, DateTime[DisplayFormat(DataFormatString = "{0:dd-MM-yyyy}", ApplyFormatInEditMode = true)]

Im not applying any custom aggregates or similar, and in this example I had 1 column, 1 row property and 'count' of ItemID value.

The code works fine with LocalDataProvider (though not using wrappers there, instead more complex EF entities), but wit h my lighter QueryableDataProvider datasource it now my export throws an exception when it hits the serialize command `provider.Serialize(this.xPivotGrid_Reports.DataProvider)`

---

An exception of type 'System.Runtime.Serialization.SerializationException' occurred in System.Runtime.Serialization.dll but was not handled in user code

Additional information: Type 'Telerik.Pivot.Queryable.QueryablePropertyAggregateDescription' with data contract name 'QueryablePropertyAggregateDescription:http://schemas.datacontract.org/2004/07/Telerik.Pivot.Queryable' is not expected. Consider using a DataContractResolver if you are using DataContractSerializer or add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to the serializer.

I cant remember original source, but I found the DataContract code online and changed very little.

And I am aware that the DataProviderSerializer subclass (where KnownTypes is defined) is called LocalDataSourceSerializer, but thats part of question: 

Is there another list like `PivotSerializationHelper.KnownTypes` I should be using, because it seems comprehensive enough and im hardly doing anything strange?

I add raddatafilter as following :

<Grid><Grid.Resources><DataTemplate x:Key="CountryComboboxTemplate" ><telerik:RadComboBox x:Name="CountryCombox2" TabIndex="3"HorizontalAlignment="Left" VerticalAlignment="Center"DisplayMemberPath="CountryName" IsTabStop="True"ClearSelectionButtonContent="Clear" ClearSelectionButtonVisibility="Visible"CanAutocompleteSelectItems="True" CanKeyboardNavigationSelectItems="True"IsEditable="True" IsReadOnly="False" IsTextSearchEnabled="True"OpenDropDownOnFocus="True" IsFilteringEnabled="True"TextSearchMode="Contains" IsDropDownOpen="False" SelectedValue="{Binding Value, Mode=TwoWay, FallbackValue=null}"Width="200" Background="{x:Null}" BorderBrush="{x:Null}" Height="30" Foreground="{DynamicResource white-forground}" Margin="0,5" Grid.Row="2" Grid.Column="2"/></DataTemplate><behaviors:EditorTemplateSelector x:Key="MyEditorTemplateSelector"><behaviors:EditorTemplateSelector.EditorTemplateRules><behaviors:EditorTemplateRule PropertyName="Country" DataTemplate="{StaticResource CountryComboboxTemplate}" /></behaviors:EditorTemplateSelector.EditorTemplateRules></behaviors:EditorTemplateSelector></Grid.Resources><telerik:RadDataFilter Name="Filter" telerik:StyleManager.Theme="Windows8"EditorCreated="OnRadDataFilterEditorCreated"Loaded="Filter_Loaded"MinHeight="193"MaxHeight="250"Width="Auto"Grid.Row="0" behaviors:FilterDescriptorBindingBehavior.FilterDescriptors="{Binding FilterDescriptors, Source={StaticResource model}}"EditorTemplateSelector="{StaticResource MyEditorTemplateSelector}"Margin="1" /></Grid>

the problem is the country not fill in the filter always country is equal too empty , not the selected country
and code behind looks like

public FilterDataUserControl(){InitializeComponent();var list = new List<FilterCriterea>();list.Add(new FilterCriterea());Filter.Source = list;}private void OnRadDataFilterEditorCreated(object sender, EditorCreatedEventArgs e){if (DataContext != null){var datacontextVm = DataContext as AdvancedSearchManagerViewModel;if (datacontextVm != null){switch (e.ItemPropertyDefinition.PropertyName){case "Country":RadComboBox countrycomboBoxEditor = (RadComboBox)e.Editor; countrycomboBoxEditor.ItemsSource = datacontextVm.CountryCollectionViewModelIns;break;}}}}private void Filter_Loaded(object sender, RoutedEventArgs e){Filter.ItemPropertyDefinitions.Add(new ItemPropertyDefinition("Country", typeof(Country), "Country"));}}

Hi, I implemented an Autocompletebox within an Edit Appointment's dialog,I was able to set the ItemsSource to be a staticresource of the viewmodel, But I can't seem to set it as a property of my CustomAppointment. May I ask how do I do that.

Also upon creation of a new appointment, I send it off to make the changes in outlook as well. But the problem is that the code below is of type IAppointment. How do I get the value of the customappointment OnSchedulerAppointmentCreated 

        private void OnSchedulerAppointmentCreated(object sender, AppointmentCreatedEventArgs e)
        {
            (this.DataContext as CalendarViewModel).NewAppointment((CustomAppointment)e.CreatedAppointment);
        }

Hey all,

So to start, let me say that I have a project built out to learn with...I'm trying things out just to figure out better patterns and whatnot when building up apps since I've been doing a lot of that lately and I've started a blog to document my experiences.

What I was doing initially was creating a project to figure out which was better to use...a BackgroundWorker or Task for doing background processing of getting a data source for the grid.  What I ended up with was a test app that is buried under a mountain of bad perf and it locks the UI up until it's darn good and ready to let it go.  As far as I can tell in my source code...I'm not attaching any of the BackgroundWorker or Task threads to the UI thread...so I'm pretty confused as to what's going on.

If I just do one at a time, the table starts filling up with data before the RadBusyIndicator can even bring up it's UI...if I try 2 or 3...I start seeing the RadBusyIndicator doing it's thing...but the UI is still responsive.  If I do all 12...the UI is stuck for a good 10 minutes (my test database has more than 250,000 records in each table).

My source files can be found at the following blog post (If you'd rather I posted them here I can do that as well...)

Any thoughts as to what I'm doing wrong?  Thanks in advance.  :)
