My Series data is decided in run-time.

Below my xaml code.

            <telerik:RadCartesianChart.SeriesProvider>
                <telerik:ChartSeriesProvider Source="{Binding Series}">
                    <telerik:ChartSeriesProvider.SeriesDescriptors>
                        <telerik:CategoricalSeriesDescriptor ItemsSourcePath="Data" ValuePath="Value" CategoryPath="Time" >
                            <telerik:CategoricalSeriesDescriptor.Style>
                                <Style TargetType="telerik:LineSeries">
                                    <Setter Property="StrokeThickness" Value="1"/>
                                    <Setter Property="Visibility" Value="{Binding Name , Converter={StaticResource pointFocusConverter}}"/>
                                    <Setter Property="LegendSettings">
                                        <Setter.Value>
                                            <telerik:SeriesLegendSettings Title="{Binding Name}"/>
                                        </Setter.Value>
                                    </Setter>
                                    <Setter Property="VerticalAxis">
                                        <Setter.Value>
                                            <telerik:LinearAxis/>
                                        </Setter.Value>
                                    </Setter>
                                </Style>
                            </telerik:CategoricalSeriesDescriptor.Style>
                        </telerik:CategoricalSeriesDescriptor>
                    </telerik:ChartSeriesProvider.SeriesDescriptors>
                </telerik:ChartSeriesProvider>
            </telerik:RadCartesianChart.SeriesProvider>


In this code, 'StrokeThickness', 'Visibility' and 'LegendSettings' is confirmed binding
According to other code,  'VerticalAxis' property is dynamically making Yaxis.
But does not working.
Please help me.

Hi,
in my application I'm recording values at run-time. So I add series dynamic to my chartview. Next step would be to add vertical axis dynamically to my chartview.
So I added a collection where I can add the axis at run-time. Then when I want to change from one axis to another i got a InvalidOperationException: Specified element is already the logical child of another element. Disconnect it first.

Here is my SeriesProvider:

Is there another way to do this?

I have the following custom control:


I want to add a close button to the header, to the right of where the minimize and maximize buttons appear normally. I've googled for this problem and every solution I come across involves assigning a custom template to an unextended RadTileViewItem. I don't know how to convert these solutions for application to a custom control. I've tried multiple solutions from this website so far, but I can't get it to work.

Good afternoon,

I've read a 2009 thread saying it was not possible to export a chart in vector graphic, but only as images. As it is very important for our application, I wanted to ask wether it is still the case today ? And if it is not the case, is there a way to access graphical elements and reconstruct the graphic ?

Thank you,

Hello Friends,

I have just started working with Telerik UI for WPF and currently working on the RadDiagram.

After going through the Documentation, i am looking forward for some code samples for  RadDiagram.

Also just want your guidance how and where should i start leaning Telerik UI for WPF .

I am creating some rather large diagrams that take some time to load, so I am using a busy indicator to display while the diagram loads. I run this busy indicator in a background thread to keep the UI responsive. Once the loading is complete in the RunWorkerCompleted method I set the GraphSource property in my ViewModel which is bound to my diagram. I am subscribing to the GraphSourceChanged event of the diagram, at which point I set the layout to be ​'TreeLayoutType.TreeDown'. 

This was working perfectly until I introduced the busy indicator on a seperate thread. The GraphSourceChanged still gets called at the appropriate time however the diagram does not layout at all with all of the diagram items stacked on top of each other. Im assuming this is a threading issue, but thought it would work correctly as in setting the databound GraphSource property on the RunWorkerCompleted which should be using the UI thread.

Any help appreciated.

Hi,

I have a problem serializing and deserializing a business object, expanding on your examples:
http://www.telerik.com/help/wpf/raddiagram-howto-drag-custom-toolboxitem.html (1)
http://www.telerik.com/help/wpf/raddiagram-extensions-toolbox.html#PopulateWithCustomData (2)

Your examples work just fine (when I changed the geometry handling, because of localization issues, I think).
But when I try to add more properties, and serialize them, I get an error deserializing the objects.

After searching, I have now found this thread:
http://www.telerik.com/forums/adding-my-own-properties-into-settingspane-of-raddiagram-on-selection-of-shape (3)
In this thread, Zarko writes (in September 13th 2012):
...
"As for your second question - unfortunately at the moment the RadDiagram supports only string serialization."

I now have to ask: Is this still the case? I would expect serialization to have been handled way before now.
And if this is the case, how can I get around this? Can you come with a solution so that I can handle what I am trying in my example (see below)?

Thank you very much!



I have the full sample project as png files attached, but here is the issue from my point of view:

namespace DeserializationProblem
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            SerializationService.Default.ItemSerializing += Default_ItemSerializing;
        }

        void Default_ItemSerializing(object sender, SerializationEventArgs<IDiagramItem> e)
        {
            if (e.Entity is RadDiagramShape)
            {
                Geometry g = (e.Entity as RadDiagramShape).Geometry;
                string g_string = GeometryParser.GetString(g);               
                e.SerializationInfo["MyGeometry"] = g_string;
                if ((e.Entity as RadDiagramShape).DataContext is MyShape)
                {
                    e.SerializationInfo["DataContent"] =
                        ((e.Entity as RadDiagramShape).DataContext as MyShape).Header;

                    e.SerializationInfo["DataContent2"] =
                        ((e.Entity as RadDiagramShape).DataContext as MyShape);
                    var test = (MyShape)e.SerializationInfo["DataContent2"];    // <- Works fine
                }
            }
        }

        private void radDiagram1_ShapeDeserialized(object sender, ShapeSerializationRoutedEventArgs e)
        {
            if (e.Shape as RadDiagramShape != null)
            {
                //SerializationInfo e_info = (SerializationInfo)e.SerializationInfo["MyGeometry"];
                string e_info_string = e.SerializationInfo["MyGeometry"].ToString();
                Geometry g = GeometryParser.GetGeometry(e_info_string);               
                (e.Shape as RadDiagramShape).Geometry = g;

                (e.Shape as RadDiagramShape).Content = e.SerializationInfo["DataContent"].ToString(); // <- Works
                var test = (MyShape)e.SerializationInfo["DataContent2"];    // <- Breaks
                // Error: Unable to cast object of type 'System.String' to type 'DeserializationProblem.MyShape'.
                // e.SerializationInfo["DataContent2"] is now a string "DeserializationProblem.MyShape"
            }
        }
    }
}  
 

Hello,

I am having some problems on our solution with the IColumnFilterDescriptor.

Here is our C# implementation :


The problem occurs when we in the gridview, we have 2 different item types at the same level. Here is the error we are getting on the columnDescriptor.ResumeNotifications() event :
ArgumentException :
The value "(Empty) AND ((Title Contains ma) AND (Title IsNotNull null))" is not of type "Telerik.Windows.Data.IFilterDescriptor" and cannot be used in this generic collection.
Parameter name: value

We are following the examples shown on your site.
We've been trying to figure out this problem for ours without any success. Any idea where this problem comes from?

Hi,

I created a usercontrol base on a ScheduleView. My user control contain a "OnCanDrop" event and a "SetDataSource" method. When I create my UserControl, I fill the view with ReadOnly slots. The user can use the "SetDataSource" method to fill the view with "Appointments" and "SpecialSlots". Appointments is for appointments and SpecialSlots is for open slots where user can drag apointments into it of where user can create new appointments.

My objects (appointments and special slots) contain specifics members for logical purpose.

What I'm trying to do in my a drag and drop behavior, it's to raise my event with the source appointment the user is dragging and the specialslot where the user is trying to drop or drag over so the user can decide if the appointment is trying to drag can be drop or not on the specialslot I raised through my event base on a logic he decided.

If I have an appointment from 8h00 to 8h15 and I want to drag it in the special slot 8h15 to 8h30. I want to raise my event only when I'm over the special slot not after each mouse move of my appointment.

Thank's
Alain

Hi,

May i know how can i accomplish this pls?

http://clip2net.com/s/7e5IEa

Our requirement is to use car icons as MapPinPoint. I already accomplish that using this code


Our next requirment is to put a tooltip like popup whenever the user clicks on the icon car. It also has some labels or buttons on the bottom. it must trigger an event like click on the backend whenever clicked. example "Send a message" it will trigger click event of that "send message button" to show a form.


May i ask how is this possible? im having a hardtime doing this. can i have a sample project from you?

THanks
