I downloaded the WPF demo app to get examples on how to create UI items similar to the examples.  I'm finding that I'm always missing references and have to google which reference I need for certain controls.  I also can't find resources, not sure if they are in another library or if they were omitted from the source code.  It's getting frustrating to struggle with every control.

Right now I'm trying to get the RadPieChart to work so I copied in the markup into my page and the RadPieChart wasn't found.  I had to google to find out I was missing a reference to Telerik.Windows.Controls.Chart. 

Now I got that working but noticed I was missing some styles which I found in the Resources.xaml.  When I copy in those styles they have "basedon" set to another style and I don't know if it's missing or if it's a reference.

Any chance these demos could be easier to copy in so I don't have to google everything and figure it out, I don't need anything fancy, I just need it to work so I can start fiddling around with it.

For reference I'm looking at the Layout Control and trying to get a little doughnut pie chart like in the steps per day.

I have a very simple wizard that contains 3 pages. The first page should always be shown and is the starting point for the wizard. Now, I have the SelectionChanging event hooked up on the wizard to perform some validation before allowing the user to move on. However, here is where the trick comes in:I would like to be able to skip step two if certain conditions are met and move the user directly to the last page of the wizard. Likewise, as long as this condition is met, if the user then clicks Back to go to the previous step, I'd like to take the user to the first page in this scenario.

I cannot remove the second page of the wizard because this page may be needed in some cases depending on whether the specified criteria is met. Apparently, setting the Wizard's SelectedPage property to the page I want isn't the right way to do it because it puts the wizard into an infinite loop where it keeps going between the first page and the last page because when I set the SelectedPage to the last page, the SelectionChanging event is raised again, but this time with the direction saying Backward which gets the wizard to go back to the first page since the OldPage is now the last page and the direction is Backward and the criteria for skipping the middle step is met, the SelectedPage is set back to the first page which raises the SelectionChanging event with the direction Forward and the OldPage being the first page... and round and round we go.

I'm looking for a solution that doesn't require me to add or remove pages to the collection on the fly and doesn't briefly navigate to the second page in a fashion that it creates a "stutter" to the user where it's obvious that the software is simulating the user clicking the next button when the second page is active.

TIA.

I want to display an image editor withuot tools. (I need only the ability to control the brightness and contrast, what I can do programmatically).

I want the image will be displayed fully in the image editor, without scrolling.

How can I do that?

Hi,

https://github.com/telerik/xaml-sdk/tree/master/ChartView/WPF/SeriesProvider

# SeriesProdvider project

1. Add new item : window1.xaml (include one button)

 2. app.xaml  StartupUri   set  window1.xaml 

 3.  window1.xaml  button client event

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            MainWindow w = new MainWindow();
            w.ShowDialog();
        }

4. Run button click - PopupWindow Open & Close (Loop.. Loop.. Loop)

5. Memeory Leak check

I found a solution

        public MainWindow()
        {
            InitializeComponent();
            this.Unloaded += MainWindow_Unloaded;               
        }
        private void MainWindow_Unloaded(object sender, RoutedEventArgs e)
        {
            chart.SeriesProvider.Source = null; 
        }

I want to more best solution, for plan MVVM project

While implementing the LayoutControlExpanderGroup in my project I thought the doughnut charts shown in the WPF example were quite nice visually so decided to use those for weights on transactions.  After many days of struggling to reproduce the code I finally got something somewhat working but I'm still having problems.  I don't know where to set the max value of a chart, I'm guessing the example has it set at around 15,000 since even 11234 steps on Feb, 09 is still a ways away from the max.  My weights go from 25,000 up to 170,000 so even the lowest weight show 100% filled.  I can't find documentation on where to set this max value.

I'm also having a hard time wrapping the text in the middle.  I have a date time that has year/month/day followed by a space then hour/minute.  For some reason it's all on the same line and goes outside the doughnut.

My XAML is quite similar to the example in the StepsPerDay.xaml in the Layout Control demo (first look).  I just have different properties bound to it.

<telerik:RadPieChart Palette="Flower"
                         Style="{StaticResource ChartStyle}">
                        <telerik:RadPieChart.Series>
                            <telerik:DoughnutSeries ItemsSource="{Binding Transaction.Weights}"
                                    InnerRadiusFactor="0.75"
                                    RadiusFactor="1"
                                    ValueBinding="Weight">
                                <telerik:DoughnutSeries.AngleRange>
                                    <telerik:AngleRange StartAngle="270" />
                                </telerik:DoughnutSeries.AngleRange>
                                <telerik:DoughnutSeries.SliceStyles>
                                    <Style TargetType="Path">
                                        <Setter Property="Fill" Value="{Binding DataItem.WeightFill}" />
                                    </Style>
                                </telerik:DoughnutSeries.SliceStyles>
                                <telerik:DoughnutSeries.LabelDefinitions>
                                    <telerik:ChartSeriesLabelDefinition Margin="20">
                                        <telerik:ChartSeriesLabelDefinition.Template>
                                            <DataTemplate>
                                                <StackPanel>
                                                    <TextBlock Text="{Binding DataItem.WeightDisplay}" 
                                                               Style="{StaticResource BoldLabelStyle}" />
                                                    <TextBlock Text="{Binding DataItem.WeighInTimeDisplay}"
                                                               Foreground="Black"
                                                               TextWrapping="Wrap"
                                                               TextAlignment="Center" />
                                                </StackPanel>
                                            </DataTemplate>
                                        </telerik:ChartSeriesLabelDefinition.Template>
                                    </telerik:ChartSeriesLabelDefinition>
                                </telerik:DoughnutSeries.LabelDefinitions>

I'm using the RadCollectionNavigator in a WPF UserControl.  

The CurrentItem Is Bound, TwoWay to a DataContext property.

Everytime I navigate using the RCN's navigation buttons the CurrentItem setter is called 3 times.

I using ReferenceEquals() to ignore additional calls to the setter with the same value but this causes other problems.

Will I need to override the built in navigation buttons to eliminate this behavior?

<telerik:RadCollectionNavigator Source="{Binding EvidenceItems}" CurrentItem="{Binding CurrentNavItem, Mode=TwoWay}"/>

private EvidenceGridData _CurrentNavItem;
        public object CurrentNavItem
        {
            get { return _CurrentNavItem; }
            set
            {
                if (ReferenceEquals(_CurrentNavItem, value))
                    return;

                _CurrentNavItem = value as EvidenceGridData;
                RaisePropertyChanged(nameof(CurrentNavItem));
            }
        }

Hi all,

I know I can overwrite all the style of the docking controls, but I was wondering if there is an easier way to do what I want.
I want that when I have the mouse focused inside my control that is inside a RadPaneGroup the border would be highlighted just like the picture have attached.

Thanks for your help

I am attempting to mimic the Windows 10 behavior where dragging a tile to an "empty" area automatically creates a new group. Since "Group" is implemented as a "property path" in the RadTileList I am not seeing an obvious way to implement this functionality.

Should I create a new ContentControl that has special "Drop" functionality that creates a new group? Or is there a better option using the TileList itself?

On the same project I am attempting to "save" the position of Tiles across sessions, is there a "TilePosition" property that I am just not finding such that I can save the position of specific tiles or is the position of the tiles dictated by the order of the items in bound ObservableCollection?

Cheers!

Hi,

I have a RadImageEditor that I am using as an image viewer, and I have added my own toolbar with buttons bound to the commands for rotating and flipping the image, which all works fine. 

However, the buttons remain disabled until I click on the image, but I would really like the user to be able to just click on one of the buttons without having to first click on the image.  Equally, if they click on the zoom control, this gets the focus and the buttons once again get disabled.

How can I permanently enable these buttons?

Thanks,

Brian
