Hi.

Additionally, I have a question.

It is event about RadCartesianChart.

I want to occur event when data of chart is changed.

example code part. 

------------------------------------------------------------------------------------------------------------------------

chart.xaml
<telerik:RadCartesianChart.SeriesProvider>
                <telerik:ChartSeriesProvider Source="{Binding Series}">
                    <telerik:ChartSeriesProvider.SeriesDescriptors>
                        <telerik:CategoricalSeriesDescriptor ItemsSourcePath="Data" ValuePath="Value" CategoryPath="LocalTime" >


chartViewModel.cs
Series type is ObservableCollection<TrendSeries>

    public class TrendSeries
    {
        public string Name { get; set; }
        public ObservableCollection<TrendData> Data { get; set; }
        public string Unit { get; set; }
        public short Place { get; set; }
    }

    public class TrendData
    {
        public double Value { get; set; }
        public short Place { get; set; }
        public string LineName { get; set; }
        public string Time { get; set; }
        public string Color { get; set; }
        public DateTime LocalTime { get; set; }
    }

in timer event(tick)

........
ObservableCollection<TrendData> data = Series[i].Data;

data.Add(....)

------------------------------------------------------------------------------------------------------------------------

Finally, when 'data' is changed, some event occur.

What should I do for it?

When using the ColorEditor, there is an option to hide or collapse the Alpha slider. However, the user can still alter alpha settings in the hex representation TextBox. How can I prevent this? I would still like the user to be able to interact with the TextBox, but I don't want them to change the color's transparency.

Hi,

I just update to Q3 2014.
RadDiagram has a style in a dictionary like this


BEFORE the update Routing worked - after the update I just had straight lines.
Adding RouteConnections="true" directly with the control made it work again.

So this is just informational.

We want to connect two ends of a RadDiagramConnection using a collection of points in the domain that can vary.  So it be useful to bind directly to the ConnectionPoints collection in the XAML.  Any way to do this?

Hi Telerik,

I have a problem, i want to use the property Direct2DRenderOptions. But that property does not show up, see attached image.

When i build the application using that property i get the error "The tag 'Direct2DRenderOptions' does not exist in XML namespace 'http://schemas.telerik.com/2008/xaml/presentation'."

I am using the Telerik version 2014.2.617.40.

I have followed the instructions on the link below:
http://www.telerik.com/help/wpf/radchartview-features-rendering.html

So is this property removed? Or does this rendermode not exist for ScatterLineSeries?

Best regards,
Jeppe

How do i go about drawing a simple line, in the diagram?

I only want i line with only two selection/resize point?

Do you have a example or something, have tried using both PathTool and PencilTool, with no luck.

Hi,

After upgrading telerik dll from version "2011.1.0315.35" to version "2014.2."   there is error occour :

Could not load type 'Telerik.Windows.Controls.TemplateVisualStateAttribute' from assembly 'Telerik.Windows.Controls, Version=2014.2.729.45, Culture=neutral, PublicKeyToken=5803cfa389c90ce7'. Line 2497 Position 280.' 

Is any thing missing while upgrading telerik dll.

Thanks,

We are implemting a diagram with geometry shapes. These shapes is meant to be inserted in a work "Shapes" way. Meaning this:

User select a circle from the ribbon, and the cursor changes to cross.
Now when the user press and hold left mouse button (MouseLeftButtonDown), the shape is inserted and a resize operation is started.

My problem is i have some trouble starting the resize operation.

I have tried in PreviewMouseLeftButtonDown to set handle, and change the ActiveTool to ResizeSENW, and call ResizeIntialise on the Resize service.

This with no luck. Can you guys point me in the right direction to achieve this.

Regards

Hi,

I can't figure out how to correctly use the EditorTemplateSelector with the RadPropertyGrid. I just want to apply custom DataTemplates for different types of properties. The applying parts works as expected but I don't understand how to get the DataContext to work. DataContext inside the DataTemplates is always pointing to the top level object that is bound to the RadPropertGrid as Item. It would really make more sense to me to have the specific property (or PropertyDefinition) as DataContext. So, how do I bind to the specific property from the Editor-DataTemplate?

Thanks for your help!

Hi,

I have a special need where I have 2 gridViews side by side. They have their own data source, but always the same number of rows.
I have to adjust the height for each row, and take the vale of the ighest row.

This is needed to ensure that vertical scrolling is always synchronized.

I tried to work with the RowLoaded event, but a this point, the Height is always "NaN" and ActualHeight is always 0.0.

Do you have an idea how I can perform this? Maybe in another event ?

Thanks,
Ben
