Hi,

I want to split the progress bar. i.e Upto particular point i want one color, remaining will be another color.

For example with following code

<

 

 

telerik:RadProgressBar x:Name="pb" Width="220" Height="15" Minimum="0" Maximum="100" Value="10" Margin="40,4,0,4" />

 

 

 

Upto say value=30 i want grey color and above that point i need default color.

Please suggest/provide sample code.

Regards

Sreeju

Hi,

I have two questions:

1- is it possible to set the default value of the zoomcontroller to "automatic" instead of 100 %?  if possible in XAML, or in code-behind is necessary

 

2- is there a way (documented or code snippet) so I can filter the export format (i.e.: I only want PNG files)

 

Thanks

I have a radgridview with a bunch of columns. Each column has defined how to group and sort.

For instance:

  • The data: MeetingDate is a of a custom type, which has a Tostring()-override that returns the datetime as date only (and implements IComparable<T>, IEquatable<T>
  • GroupHeaderTemplate: Writes the date if there is one. Writes "None" otherwise
<telerik:GridViewDataColumn x:Name="_meetingDateColumn" IsReadOnly="True"
                                Header="Meeting date"
                                DataMemberBinding="{Binding MeetingDate.TheDateTime, UpdateSourceTrigger=PropertyChanged}"
                                GroupHeaderTemplate="{StaticResource GridDateColumnGroupHeaderTemplate}"
                               Width="SizeToCells"
                                GroupMemberPath="MeetingDate">
                                <telerik:GridViewDataColumn.HeaderCellStyle>
                                    <Style TargetType="telerik:GridViewHeaderCell">
                                        <Setter Property="ToolTipService.ToolTip" Value="Date when meeting is taking place"/>
                                        <Setter Property="ToolTipService.ShowDuration" Value="{x:Static Member=system:Int32.MaxValue}" />
                                    </Style>
                                </telerik:GridViewDataColumn.HeaderCellStyle>
  
                                <telerik:GridViewDataColumn.CellTemplate>
                                    <DataTemplate >
                                        <TextBlock VerticalAlignment="Top"
                                                Text="{Binding MeetingDate.TheDateTime, StringFormat={}{0:g}}"
                                                ToolTipService.Placement="Center" />
                                    </DataTemplate>
                                </telerik:GridViewDataColumn.CellTemplate>
                            </telerik:GridViewDataColumn>


I have around 20 columns, some are dates like the one above. One is industry, which groups by the category (http://ec.europa.eu/competition/mergers/cases/index/nace_all.html) but the column sorts by the entire industry name. Others are completely different - most have special handling of grouping and sorting.

The user is supposed to play around with grouping and sorting to find interesting stuff. However  - in addition - I would like to provide a few preset options, which the user should be able to choose in a drop down and have the grid re-arrange itself accordingly.

I would hate to implement all 20 grouping and sorting again - is there any way I can reuse the defination of sort and group from the columns in the gridview - and apply them to the radgridview group panel programatically ?

 

Thanks,

I am trying to chart a variable number of series, any of which can either be displayed as point series (using bar series) or line series. I've managed to get TypePath to work to successfully vary the series type dynamically. However, I have 2 questions:

1. How can I apply Styles to the two different types of series? CategoricalSeriesDescriptor only takes a single Style, and that Style only accepts Properties of the specified TargetType; I can't figure out how to set styles for each series type.

2. (How) can I use a converter to supply the ChartView with the Series Type so that the ViewModel in MVVM doesn't have to supply telerik types to the View? TypePath doesn't allow a binding (I get "System.Windows.Data Error: 2 : Cannot find governing FrameworkElement or FrameworkContentElement for target element." if I try) so I can't apply the "Converter" tag.

If there's a better way to display variable numbers of series using 2 different series types please do point it out as well.

Thanks,
Louis

I'm using the RadCartesianChart and the ScatterPointSeries for the chart view and was wondering if there is a way to permanently show the origin (0,0) on the axis.

I have the Minimum and Maximum of each axis defined by the points that are being plotted... so for instance it can occasionally display something like

X-Axis: min -0.034... to max 0.02...
Y-Axis: min -0.04... to max 0.035... etc.

The major grid lines obviously tries to account for the spacing between the min and max to produce equally spaced lines. This sometimes obscures the origin axis lines. I have been able to mitigate this is some situations by forcing the min and max to be equal absolute values... 

Taking my earlier example for instance, making:

X-Axis: min -0.04 to max 0.04
Y-Axis: min -0.04 to max 0.04

[See attached image "Test Working"]

Sometimes depending on the min/max and the spacing decided, the axis origin is still being hidden.

[See attached image "test Not Working"]

I was wondering if there is any way to force the origin (0,0) to be displayed at all times, i'm unable to find an option in the documentation, perhaps as a major grid line etc.

Hi to all,

I doìt understand why I have several problems with Theme.

I can't see Theme applyed at design-time, when I run my project it works all perfectly.

Why?!?

I tryed to change Theme by wizard (configurator), but it not takes effect.

I tryed to clear cache of VS also, but nothing.

Hello. I have simple example

XAML:

<telerik:RadComboBox 
    Width="100" Height="25"
    IsEditable="True" 
    Text="{Binding Value, Mode=TwoWay}" >
            <telerik:RadComboBoxItem Content="20"/>
            <telerik:RadComboBoxItem Content="10"/>
            <telerik:RadComboBoxItem Content="2"/>
            <telerik:RadComboBoxItem Content="1"/>
</telerik:RadComboBox>

 

ViewModel:

    public class ViewModel {
        public int Value { get; set; }
    }

 

Behavior:

    public partial class MainWindow : Window {
        public MainWindow() {
            InitializeComponent();

            DataContext = new ViewModel() { Value = 2 };
        }
    }

ComboBox selected another value instead of '2'
