Hello,

I followed your tutorial to use the RadDataPager and RadGridView. The pager is bound to the view model source items and the Rad Grid View is bound to the RadDataPager. See the following example:

<Grid x:Name="LayoutRoot" 
        Background="White">     
    <Grid.RowDefinitions> 
        <RowDefinition /> 
        <RowDefinition Height="Auto" /> 
    </Grid.RowDefinitions> 
    <telerik:RadGridView x:Name="radGridView" 
                         ItemsSource="{Binding PagedSource, ElementName=radDataPager}" 
                         AutoGenerateColumns="False"> 
        <telerik:RadGridView.Columns> 
            <telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" /> 
            <telerik:GridViewDataColumn DataMemberBinding="{Binding CompanyName}" /> 
            <telerik:GridViewDataColumn DataMemberBinding="{Binding Title}" /> 
        </telerik:RadGridView.Columns> 
    </telerik:RadGridView> 
    <telerik:RadDataPager x:Name="radDataPager" 
                          Source="{Binding Employees}" 
                          PageSize="5" /> 
</Grid> 

I can see that the pager splits the items into pages of 50 items (I have 10 pages) but the RadGridView shows all the items. Only if I force the reload of the xaml (with Hot Reload), the RadGridView is updated according to the pager items in the current page, until that point all the items are shown.

What am I doing wrong?

Hey, I have using your control RadMenuGroupItem with ItemsSource that is Observable Collection of string. I noticed that for name with underscore in them, the underscore is removed from the name. Here an example:

telerik_123 will turn to telerik123

I use the same ItemsSource in a RadComboBox and in there I don't have this issue.

What can I do to solve this?

Sincerely, Omer 

Is it possible to drag to All Day Events and drag from All Day Events?

As can be done in Outlook

Would appreciate help

I have the following class

Class My Class

Class MyClass()
{
   public int Var1 {get; set; }
   public int Var2 {get; set; }
}

i want the selected item to show {var1}/{var2}
for now im doing (for now) is

DisplayMemberPath = "Var1"

but because its a String and a Dependency property i cannot attach a MultiBinding
and RadMultiColumnComboBox  does not have itemTemplate property
how can i achieve it

P.S 
I want the same behavior for the tooltip

p.s 2
i also want to center the selected text but it seems HorizontalContentAlignment  is not working


Thanks in advance

Hello Im Working with the RadSlider in the RadScheduler.

I've used the RadSlider_OnDragDelta Method to change the view definition. Works as intended atm.

But I've got a problem. If somebody just klicks on the slider (left or right of the Darg-Bar) to make the Bar hop on that spot, the event doesn't get fired.

So I've found several events if somebody drags the silider. But what if somebody just klick on the Slider?

Is there a event i can catch this behaviour?

best regards

Hy everyone,

I have a collection from DB:

var dynamicOutput = _sql.LoadData<dynamic, dynamic>(@"SELECT * FROM " + procedura.Trim() + "(@IdRamura, @DataRef)", p);

RaportRentabilitateGrid2.AddRange(dynamicOutput );

private ObservableRangeCollection<ExpandoObject> _raportRentabilitateGrid2 = new ObservableRangeCollection<ExpandoObject>();
public ObservableRangeCollection<ExpandoObject> RaportRentabilitateGrid2 {
            get { return _raportRentabilitateGrid2; }
            set {
                _raportRentabilitateGrid2 = value;
                OnPropertyChanged(nameof(RaportRentabilitateGrid2));
            }
}

So far everything works ok

I have the RadGridView:

<telerik:RadGridView x:Name="oRaportRentabilitateDet1" DockPanel.Dock="Top"
                                         Style="{StaticResource ContasGridviewStyle}"
                                         Background="White"
                                         AutoGenerateColumns="True"
                                         SelectionUnit="FullRow"
                                         SelectionMode="Single"
                                         HorizontalContentAlignment="Left"
                                         RowIndicatorVisibility="Collapsed"
                                         ShowGroupPanel="False"
                                         IsReadOnly="True"
                                         SelectedItem="{Binding SelectedRaportRentabilitateGrid2,Mode=TwoWay}"
                                         ItemsSource = "{Binding RaportRentabilitateGrid2, Mode=TwoWay}"
                                         VerticalAlignment="Stretch"
                                         Margin="5,0,5,10"
                                         IsSynchronizedWithCurrentItem="True"
                                         IsFilteringAllowed="False"
                                         ScrollViewer.VerticalScrollBarVisibility="Auto"
                                         ScrollViewer.HorizontalScrollBarVisibility="Auto">

And, for formatting the column in the RadGridView with the name DATA, i have the code:

            var delaColumn = oRaportRentabilitateGrid2.Columns["DATA"] as Telerik.Windows.Controls.GridViewDataColumn;
            delaColumn.DataFormatString = "dd.MM.yyyy";

But, it's not working...

I can't figure out why...

Thanks a lot.

Our application uses Telerik.Windows.Controls.RadDiagram to arrange RadDiagramItem instances on the screen.  Our view model uses a higher resolution than 96x96.  When I set RadDiagramItem.Width, for example, to 94.464, I can see in the debugger the framework accepts that value.  However, when I execute the undo operation, I see RadDiagramItem.OnSizeChanged(Size newSize, Size oldSize) called, with oldSize = {94, ... }.  This results in a rounding error in our view model.

Is there any way to put RadDiagram into a fractional pixel mode?

Dear Team,

I wanted to try the Radbarcodereader in WPF. I opened a new project with .Framework 4.7 

and i just pulled out a Radbarcodereader to an empty WPF window.

Simply started the app, and browsed some random images with barcodes, but every time i push the "decode image" i get IndexOutOfRangeException from the control.

All propertises of the control are on default, what do i have to set up to make it work?

I have tried without control, only by code:

    Private Sub Button_Click(sender As Object, e As RoutedEventArgs)
        Dim imageSource = img_Camera.Source
        Dim decoder As New BarcodeDecoder()
        decoder.ImageSource = imageSource
        AddHandler decoder.DecodingComplete, AddressOf OnDecodingComplete
        decoder.StartDecoding()
    End Sub
    Private Sub OnDecodingComplete(ByVal sender As Object, ByVal e As DecodingEventArgs)
        Dim decodeResult As String
        If String.IsNullOrEmpty(e.ErrorMessage) Then
            decodeResult = String.Format("Code Type: {0}" & ControlChars.Lf & "Result: {1}", e.CodeType, e.Result)
        Else
            decodeResult = e.ErrorMessage
        End If
        txt_RESULT.Text = decodeResult
    End Sub

At this line:     decoder.StartDecoding()

i also  get the IndexOutOfRangeException 

Please help :)

thanks

Peter B.
