Hello,

I am trying to implement MVVM pattern using RadGridView.
I have a People property as the ItemsSource of the Grid.
Now, I also have a SelectedPeople property that I want to bind to the grid (Two Way).
Anyone knows how can that be supported in RagGridView?

Thanks!

Hi,
Copying from a TFS PBI Description into a rad Rich Text Box does not work.
Could this be due to different rich text formats and is there a way to fix this ?
Thanks

Hi.

I have one problem.

My source is below.

             <telerik:RadCartesianChart.SeriesProvider>
                <telerik:ChartSeriesProvider Source="{Binding Series}">
                    <telerik:ChartSeriesProvider.SeriesDescriptors>
                        <telerik:CategoricalSeriesDescriptor ItemsSourcePath="Data" ValuePath="Value" CategoryPath="LocalTime">
                            <telerik:CategoricalSeriesDescriptor.Style>
                                <Style TargetType="telerik:LineSeries">
                                    <Setter Property="StrokeThickness" Value="1"/>
                                    <Setter Property="Visibility" Value="{Binding Name , Converter={StaticResource pointFocusConverter}}"/>
                                    <Setter Property="ShowLabels" Value="{Binding Path=DataContext.Ribbon.IsShowLabel, RelativeSource={RelativeSource AncestorType={x:Type UserControl}}}"/>
                                    <Setter Property="LegendSettings">
                                        <Setter.Value>
                                            <telerik:SeriesLegendSettings Title="{Binding Name}" />
                                        </Setter.Value>
                                    </Setter>
                                    <Setter Property="VerticalAxis">
                                        <Setter.Value>
                                            <MultiBinding Converter="{StaticResource multiVerticalAxisConverter}">
                                                <Binding Path="Data"/>
                                                <Binding Path="DataContext.Series" ElementName="lineChart"/>
                                            </MultiBinding>
                                        </Setter.Value>
                                    </Setter>
                                </Style>
                            </telerik:CategoricalSeriesDescriptor.Style>
                        </telerik:CategoricalSeriesDescriptor>
                    </telerik:ChartSeriesProvider.SeriesDescriptors>
                </telerik:ChartSeriesProvider>
            </telerik:RadCartesianChart.SeriesProvider>


Currently, good work.

But I want to wort setter about [Property="VerticalAxis"]

Now chart is changed by changing [ItemsSourcePath="Data"]

But converter of 'VerticalAxis' do not work.

Why is this not work?

What should I do for working of converter ?

Hi,

Is it possible to format the GridLines inidividual for each row?  (e.g. the width or color).

Thanks

Is there a way to make either the RadMaskedNumericInput or RadMaskedTextBox accept only non negative integers?

I am a long time Telerik user, and I love the ShowColumnWhenGrouped attribute, I've wanted this functionality for a long time.  It works great when the user drags a column to the group bar, but when set in XAML with a column grouping defined in XAML, it is ignored.  Is this a bug, and is there a workaround?  Thanks.

Hi,

i can't find how to load a second combobox on demand depending  what is selected in the first combobox? For Example, i select "Audi" in
the first combobox and the second should load all Audis "A1, A2, A3, A4, A5,..." out of a csv-File!

Thanks
Best Regards

I'm trying to make a custom appointment following this tutorial. I clone the style using Right Click -> Edit Template -> Edit a Copy. The resulting code has several  ambiguous reference error. I read that the solution is to use the fully qualified namespace but I don't know which option is correct.

One of the errors is in the line 

Hello,

i am using a Gridview that is having a RadObservableCollection<T> (where T is DependencyObject, INotifyPropertyChanged) as ItemsSource. The same collection is also used in a Chartview as Datasource for a Lineseries.
Any changes in the Chart (Drag&Drop) are reflected in the Gridview and the other direction works too.

My problem is the way the editing is passed on:
I have a Double Column which is editable and reflect the values that are shown in the Chart too. But the editing changes are passed on the the chart on every keypress during the editing which is very irritating.

So lets say someone wants to enter 749 as new value the behavior is now like this:

• press key 7 -> datapoint in chart jumps to Y-Value 7
• press key 4 -> datapoint in chart jumps to Y-Value 74
• press key 9 -> datapoint in chart jumps to Y-Value 749

what i want is this:

• press key 7 -> nothing
• press key 4 -> nothing
• press key 9 -> nothing
• press return -> datapoint in chart jumps to Y-Value 749

I guess I need to block some notification sending in the BeginningEdit event and pass out the final new value only in the CellEditEnded event. But i havent been able to work out how.

Thanks in advance!

I've run into a problem where if the DataContext is set too late in the initialization/rendering process, bindings on the IsVisible property of columns are never established. Below is an example showing the problem.

If you establish the DataContext in the constructor, it works as expected; the Number column is not shown, and you can toggle its display using the checkbox.

However, if you comment out that line, run the app, and use the button to establish the DataContext after the grid has rendered, the Number column is shown even though ShowNumber is false, and the binding does not respond to changes in ShowNumber (again using the checkbox).

I found a work-around by re-establishing the binding after setting the DataContext, but this is ugly and much less maintainable.

Is there a way I can force it to update the column bindings when the DataContext is set, rather than re-creating the binding for every column on which I need to control visibility?

Thanks,
Louis
