Hi 

I am using latest version, and I found a problem about data binding  Min and Max in GaugeRange.

Xaml like this.

<Window x:Class="TelerikChartTest.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
        Title="MainWindow"
        Height="350"
        Width="525">
    <Window.Resources>

    </Window.Resources>
    <Grid>

        <telerik:RadRadialGauge x:Name="radialGauge"
                                Width="200"
                                Height="200"
                                telerik:StyleManager.Theme="Windows8">
            <telerik:RadialScale Name="scale"
                                 LabelRotationMode="None"
                                 Min="{Binding Path=Min}"
                                 Max="{Binding Path=Max}"
                                 StartWidth="0.1"
                                 EndWidth="0.1"
                                 MajorTicks="4">
                <telerik:RadialScale.Ranges>
                    <telerik:GaugeRange x:Name="range1" 
                                        Min="{Binding ElementName=radialGauge, Path=DataContext.Min1, NotifyOnTargetUpdated=True}"
                                        Max="{Binding ElementName=radialGauge, Path=DataContext.Max1, NotifyOnTargetUpdated=True}"
                                        Background="#FF1E8D00" />

                </telerik:RadialScale.Ranges>
            </telerik:RadialScale>
        </telerik:RadRadialGauge>
       
    </Grid>
</Window>

in cs file like this,

    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            this.Loaded += MainWindow_Loaded;

        }

        void MainWindow_Loaded(object sender, RoutedEventArgs e)
        {
            this.DataContext = new TestData();
          
        }
        
    }

    public class TestData : ViewModelBase
    {
        private float _min = 0;
        public float Min
        {
            get { return _min; }
            set
            {
                _min = value;
                this.OnPropertyChanged("Min");
            }
        }


        private float _min1 = 0;
        public float Min1
        {
            get { return _min1; }
            set
            {
                _min1 = value;
                this.OnPropertyChanged("Min1");
            }
        }

        private float _max = 1000;
        public float Max
        {
            get { return _max; }
            set
            {
                _max = value;
                this.OnPropertyChanged("Max");
            }
        }

        private float _max1 = 1000;
        public float Max1
        {
            get { return _max1; }
            set
            {
                _max1 = value;
                this.OnPropertyChanged("Max1");
            }
        }

    }
if I set the DataConxtext in  MainWindow_Loaded event, the display of GaugeRange  will be mess. I found if we do not set max and min value before loaded event, the display will be wrong, but in some case, the min and max value maybe get updated after loaded event, how can we handle it?

Hello,

I've currently writing a control that descends from RadRichTextBox, with an additional HtmlText dependency property, so that I can  directly bind an HTML content to the RichTextBox. To avoid performances issues, the HtmlText dependency property should be updated only when the RichTextBox loses its focus.

First problem: The OnLostFocus virtual method is never called when the control loses its focus. This is contrary to the WPF guidelines: if an On<EventName> virtual method is defined it should be called to raise the event, so that descendant classes can override this method instead of adding an event handler. This has the advantage that we are sure that the control is notified before the event listeners and can act accordingly.

Second problem: The LostFocus event is called repeatidly: justr clicking on the control, when it doesn't have the focus raises it twice.

Hello,

I have a couple of questions about the RichTextBox, I want to use this control for basic notes that are made in my application.

The user should be able to use basic format options to format the note, like bold, understrike, italics and color.

Also the text should be spellchecked, besides that I dont need any of the other features of this control.

I am trying to set this up, but have some questions:

• When I set the font in XAML the font of the text remains 12, the font of my contextmenu gets smaller but not the text in the richtextbox? How can I set this font?
• The default settings show some margins below every line, I can remove this using the contextmenu option paragraph. How can I set this in XAML?
• Is it possible to bind to some property that specify if there are spellcheck errors in the text or the number of spellcheck error in the text? So I can for example show a messagebox before the notes are saved which will tell the user that there are still spell check errors.
• I want to use the Alt+Enter key-combination for next line, the enter key will be used to move to the next field, I tried to implement this see below, but cant programmaticaly add a return in the text. How can I accomplish this?

Regards,

Marcel

Severity is an enum type. The below XAML doesn't work. If I compare on another property of Int type, the styles are selected just fine. I also tried to compare against the underlying constant value, but no cigar. Can I use the conditionalstyleselector on an Enum type?

<telerik:RadGridView ItemsSource="{Binding IssuesFound}">

<telerik:RadGridView.RowStyleSelector>

<telerik:ConditionalStyleSelector>

<telerik:StyleRule Condition="Severity = Error">

<Style TargetType="telerik:GridViewRow">

<Setter Property="Background" Value="Red"/>

</Style>

</telerik:StyleRule>

<telerik:StyleRule Condition="Severity = Warning">

<Style TargetType="telerik:GridViewRow">

<Setter Property="Background" Value="Yellow"/>

</Style>

</telerik:StyleRule>

<telerik:StyleRule Condition="Severity = Information">

<Style TargetType="telerik:GridViewRow">

<Setter Property="Background" Value="Blue"/>

</Style>

</telerik:StyleRule>

</telerik:ConditionalStyleSelector>

</telerik:RadGridView.RowStyleSelector>

</telerik:RadGridView>

Hi telerik Team,

I want to make longer the duration of tool tip visibility in a piechart, I tried several solutions but nothing seems to work.

Settings the show duration in ChartTooltipBehavior I obtain another tooltip.

here is my xaml:

How can I set the show duration on the right tooltip?

Thank,

Giorgio

i have a radGrid that bind to string with delimiter such as : string: key=value;key=value;....
i bind this string to the grid by converter from string to dictionary and back.

this is the radgrid:

this is the converter:

the currentParameter Implements INotifyPropertyChanged.

so i want to edit the values in radGrid but it's not possible because the  keyValuePair from converter is read only!

what i can do?

I'm currently testing out the Q1 2015 Trial before deciding to completely upgrade my application. One of the views in the application uses the RadRadialGauge with an interactive RadialScale. A custom ShaderEffect effect is applied to the root Grid in the application. When I navigate to the page containing the gauge, my application crashes with a UCEERR_RENDERTHREADFAILURE exception. If, however, I use one of the included effects (DropShadow or Blur) the app doesn't crash but the needle is no longer interactive. I have a sample solution I can provide if desired and will provide basic xaml below.

Any thoughts on what I might be able to do to either work around this problem or get an assurance this can be fixed? I'm considering the upgrade for some of the new WPF Reporting tools and I'd hate to not be able to do it because of the RadialGauge.

Sample MainWindow.xaml:

Hi,
