Hello, I am trying to color the CandleSticks within a RadCartesianChart but the code does not seem to be working. This is the code:

<telerik:RadCartesianChart.Series>

    <telerik:CandlestickSeries ItemsSource="{Binding currentDataSource}"
           OpenBinding="Open"
           HighBinding="High"
           LowBinding="Low"
           CloseBinding="Close" 
           CategoryBinding="FromDate"
           TrackBallInfoTemplate="{StaticResource trackBallInfoTemplate}">

        <telerik:CandlestickSeries.DefaultVisualStyle>
            <Style TargetType="telerik:Candlestick">
                <Setter Property="StrokeThickness" Value="2" />
                <Setter Property="UpStroke" Value="Yellow" />
                <Setter Property="DownStroke" Value="Cyan" />
                <Setter Property="UpFill" Value="Green" />
                <Setter Property="DownFill" Value="Red"/>
            </Style>
        </telerik:CandlestickSeries.DefaultVisualStyle>
    </telerik:CandlestickSeries>

</telerik:RadCartesianChart.Series>

Also, is it possible to have different color for some of the candlesticks according to a custom logic? For example, if the value == 200, the candlesticks should be green, otherwise red. Thanks

Hello,

I'am on edge of exasperation. XAML-DSK don't work. Demos don't work. Copy+Paste from web+forum don't work.

Isn't there a simple AND complete example working solution with Northwind sql database and any (preferably GridView)?

I simply want to 1. UNZIP, 2. Open in VS and 3. Adjust SQL connection sting in app.config and 4. RUN!

Thank you!

Hi,

In the RadRichTextBox I'm working with, I am listening to the SelectionChanged event when the user selects a piece of a string. I need to determine, within the span.Text in which the string is located, what is the position (index) within the Span.Text of the selected string.

So, for example, if the span.Text contains "This is a piece of text"

and the user selects "piece"

I want to write code that returns "10", which is the index of "piece" within "This is a piece of text"

I have tried various properties that I hoped would get me this number - eg

var range = t.Document.Selection.Ranges.First;
if (range != null)
{

       string curSpanText = t.Document.CaretPosition.GetCurrentSpanBox().AssociatedSpan.Text;
       string s = t.Document.Selection.GetSelectedText();
       int start = range.StartPosition.GetCurrentPositionInSpan();
       int end = range.EndPosition.GetCurrentPositionInSpan();
}

I hoped that "start" above would give me what I needed but it doesn't.

s gets me the string I had selected. curSpanText is the entire span's Text property. How do I find the position of s within curSpanText?

Thanks
  

Hello,

I created a user control and changed it into a RadWindow. The application is using the Windows 8 touch theme with an implicit style. The libarary version is Telerik 2014 Q3.

The Visual Studio 2013 Designer shows either an empty window or a null reference exception when I have set references to Telerik Libraries in a custom folder. The Window is shown properly when the Telerik libraries are loaded from the installation folder. 

I have used the technique as mentioned in: http://www.telerik.com/help/wpf/radwindow-how-to-use-radwindow-as-user-control.html  The exception is shown in the designer when the style is applied to the window via Style ="{DynamicResource RadWindowStyle}" instead of setting it in App.xaml. The theme xaml files are loaded from the Theme dll.

Kind regards,
Bert

After a simple replace of the DLLs and clean solution, rebuild, nothing works.


WTF!!!  No menu, no buttons, not one single Rad control is visible.

Hi Team,

We are using the Telerik controls in our application and to test the application we are using Coded UI Test 2012.

We were able to record actions on the controls placed inside the RadPaneGroup. But the playback is failing.
For the button inside the RadPaneGroup, CUIT is identifying the button control with the following hierarchy:
--->MainWindow
--->Rad Split Container
---> Rad Pane Group --->Button But it is failing to playback actions on the button. Following is the exception message with which the CUIT is failing:

---------------------------------------------------------------------------------------------------------
<<Result Message: >>
Test method CodedUITestProject2.CodedUITest1.CodedUITestMethod1 threw exception:

 Search may have failed at 'Rad Pane Group' TabList as it may have virtualized children.

This is a blocking issue. Any help in automating on the controls placed inside the RadPaneGroup is greatly appreciated.

Hi,
 
I have RadRichTextBox on my WPF Window. I am using MVVM design pattern and have binding in my View for this RadRichTextBox using TxtDataProvider as below:

<Window.DataContext>
        <local:vmRichTextBox />
    </Window.DataContext>
    <Grid>
        <telerik:RadRichTextBox x:Name="rchTextBox" Width="210" Height="150">
        </telerik:RadRichTextBox>
        <telerik:TxtDataProvider RichTextBox="{Binding ElementName= rchTextBox}"  Text="{Binding Path= MessageToSend, Mode= TwoWay, UpdateSourceTrigger= PropertyChanged}"></telerik:TxtDataProvider>
    </Grid>

Here Binding works perfect. Now, I would like the user to enter 120 characters only in above RadRichTextBox in a manner  that whenever user enters 121st character the foregoround color of this character and exceeding characters changes to Red while typing itself. The first 120 characters will have default  foreground color.
Please let me know how to implement this functionality with this RadRichTextBox in MVVM asap.

Thanks

I need to have the Richtextbox display a transparent background and border when IsEnabled is set to true.  After fumbling around for a few hours I am unable to get the control to cooperate.

Any help would be appreciated.

Hi,  

In most use-cases, I enjoy the fact that a RadGridView cell which fails validation will "trap" the user's focus, and require the user to fix the cell contents.  However, in the current project I am working on, I need to allow the user to switch focus simply by mouse-click (currently if the user enters an invalid cell, they must hit esc first), even out of cells which have failed validation.

How do I get this behavior?  

Thanks,
Dustin

Hi,

I implemented a search functionality with the PDF Viewer control. The user have the flexibility to do a findfirst, findlast, findprior, findnext and depending on what the user did, I highlight the searchtext corresponding on which action the user did. I would like to know how to scroll to the matching text I found to have it in the visible portion of the viewer.

Thank's
Alain
