[Solved] Dynamicly adding a RangeList to a Radial Gauge

I am trying to add ranges to a Radial Gauge. Code snippet:

RangeList oRangeList = new RangeList();

double nextRangeMinimum = 0;

foreach ( QualitativeRange oRange in _ViewModel.BulletGraphRanges )

{

RadialRange oRadialRange = new RadialRange();

oRadialRange.Min = nextRangeMinimum;

oRadialRange.Max = nextRangeMinimum = oRange.Value;

oRadialRange.BorderBrush = oRange.Brush;

oRangeList.Add( oRadialRange );

}

The problem is that RangeList has no .Add member. How do I add ranges to a RangeList?
Thanks.
Dan

Nevermind. Duh. It's oRangeList.Items.Add
All better now.

[Solved] How to allow custom values in GridViewComboBoxColumn

Hi,

I have a GridViewComboBoxColumn which is bound to a List of object with DisplayMemberPath and SelectedValueMemberPath set to the Name and ID properties of this object resp.

This combobox allows to enter text and I need it to accept user entered values which are not even present in its ItemSource.

Is it possible by any means?

Thanks,
Arpit

RadMaskedNumericInput ext:MaskedInputExtensions.Minimum property in style resource

I am trying to mask out negative numbers while using RadMaskedNumericInput. There was a thread on setting ext:MaskedInputExtensions.minimum="0" and that works great for us. We have about 50 RadMaskedNumericInput instances, so I added the following to our style resource xaml for RadMaskedNumericInput:

    <Setter Property="ext:MaskedInputExtensions.Minimum" Value="0" />
I am now getting the following exception:
        {"'Set property 'System.Windows.Setter.Property' threw an exception.' Line number '1423' and line position '10'."}
        {"Value cannot be null.\r\nParameter name: property"}

Can this property be in the style resource XAML? If so, how should that be specified? Any advise would be appreciated.

Thanks,
-Milt

[Solved] How to prevent MapPinPoint from moving the map?

I'm adding MapPinPoint objects to the map but every time map tries to focus the newly added pinpoint and therefore pans the map.
I don't want this behavior so how we can prevent it from automatically panning to the newly added location?

Selecting an item works only once

Hallo,

i have a problem with a RadComboBox. It's ItemsSource is an ObservableCollection<ThemeInfo>. The RadComboBox is a part of a RadRibbonBar. I bound my RibbonBarViewModel to the RadRibbonBar's DataContext property.

Here is the xaml code for my RadComboBox:

<telerik:RadComboBox
                            Name="themesRadComboBox"
                            Width="100" 
                            ItemsSource="{Binding ThemeInfos}"
                            SelectedItem="{Binding SelectedThemeInfo, Mode=TwoWay}"
                            Command="{Binding ChangeApplicationThemeCommand}"
                            DisplayMemberPath="DisplayName">
                        </telerik:RadComboBox>

If i select an item it works fine, but if i do this the second time, DropDownList of RadComboBox stays closed. If the RadComboBox has focus and i use the arrow keys it also works as expected. Any ideas to solve this?

Bind X axis label Width to ActualWidth of Bar in Chart

I need to trim the text the item labels of the x axis to the same width as the bars of my chart. Some of the labels could be quite long, so the end of one label could overlap the beginning of the next (Note: I don’t want to rotate these labels). It also needs to be able to resize if the window size changes or if the amount of bars changes.

On my template I have set the texttrimming to use CharacterEllipsis, but obviously this only works if the width is set. So I would like to bind the width of the x axis label to the ActualWidth of the Bar (or Candle).

Using Snoop I can see the ActualWidth of PART_MainContainer and a few other PART_ containers that change size with the size of window. So how do I bind to one of these PART_s? If this can be achieved using just XAML that would be great. I don’t really have code behind skills.

This is what I have so far;

>>>> x-axis label style

<Style x:Key="AxisXLabel2D" TargetType="{x:Type telerik:AxisLabel2D}">

<Setter Property="ItemLabelStyle">

<Setter.Value>

<Style TargetType="TextBlock">

<Trigger Property="IsMouseOver" Value="True">

<Setter Property="TextTrimming" Value="None" />

</Setter.Value>

</Setter>

<Setter Property="Template">

<Setter.Value>

<ControlTemplate TargetType="{x:Type telerik:AxisLabel2D}">

<Border x:Name="border" BorderThickness="1" BorderBrush="Transparent" CornerRadius="5,2,5,2"

Width="{Binding ElementName=PART_MainContainer, Path=ActualWidth}">

<TextBlock x:Name="labeltext" Style="{TemplateBinding ItemLabelStyle}">

<RotateTransform />

</TextBlock.LayoutTransform>

<TextBlock.Text>

<Binding>

<telerik:LabelFormatConverter />

</Binding.Converter>

</Binding>

</TextBlock.Text>

>>>>> The code behind that styles the chart

public MainWindow()

{

this.InitializeComponent();

this.radChart.DefaultView.ChartArea.Loaded += ChartArea_Loaded;

// Insert code required on object creation below this point.

}

void ChartArea_Loaded(object sender, RoutedEventArgs e)

{

ChartArea area = sender as ChartArea;

HorizontalAxisLabels2D axisLabelsContainer = area.FindChildByType<HorizontalAxisLabels2D>();

var axisLabels = axisLabelsContainer.ChildrenOfType<AxisLabel2D>();

System.Windows.Style style = this.Resources["AxisXLabel2D"] as System.Windows.Style;

foreach (var item in axisLabels)

{

item.Style = style;

}

Secondly, (not really a problem, but I thought I'd ask as I'm here!) Does anyone know how to make it so the CharacterEllipsis (or whatever ellipsis), could appear in the center of the word, not at the end?

For example, a full width label "Test Subject 001", trimmed to say "Test Subje..." is ok, but in this case it would be better if it said "Test Su...001". I know it's probably not the right place to post this, but any help would be great. Does anything in the RadControls do this?

Thank you in advance.
