[Solved] Creating LineSeries programmatically with custom TrackBallInfoTemplate

I am trying to change the track ball info, but I cannot figure out the right combination to get the data to come out the way I need it to come out. I want to show an identifier for a line series in much the same way that the ChartView demo does, but in that demo, the series and format strings are encoded into the XAML. In my app, there can be any number of line series, so they need to be created programmatically.

Here is the class that holds the data:

public class SalesInfo

{

public string Employee { get; set; }

public DateTime Time { get; set; }

public int Value { get; set; }

}

And here is where I am creating the data and setting the item source of my line series:

data = new RadObservableCollection<SalesInfo>(data.OrderBy(x => x.Time));

Color dataColor = colorArray[loopCounter % 4];

LineSeries line = new LineSeries();

line.Stroke = new SolidColorBrush(dataColor);

line.StrokeThickness = 2;

line.CategoryBinding = new PropertyNameDataPointBinding() { PropertyName = "Time" };

line.ValueBinding = new PropertyNameDataPointBinding() { PropertyName = "Value" };

line.ItemsSource = data;

var tbiTemplate = this.Resources["theTemplate"] as DataTemplate;

line.TrackBallInfoTemplate = tbiTemplate;

activitiesAddedChart.Series.Add(line);

And finally the template in the resources:

<DataTemplate x:Key="theTemplate">

<StackPanel Orientation="Horizontal">

<TextBlock Text="{Binding DataPoint.SalesInfo.Employee}" />

<TextBlock Text=": " />

<TextBlock Text="{Binding DataPoint.Value}" />

</StackPanel>

</DataTemplate>

I cannot figure out how to get this bound correctly so that I can see the Employee name in the track ball info. I get the Value fine, and if I use DataPoint.Category, I can get the date, but I just cannot figure out how to get the Employee to show up in that first TextBlock in the template. Thanks.

KeyTipService - wrong position

Hi,
I use 2 screens and when I implement keytips they don't appear in the right position related to my application.
(I open up my application on my right screen, the "main display screen", but when I trigger the keytips they appear on my left screen...!)

Are there any settings I have to apply to "connect" the keytips to my application in any way...so that they always appear "in the right position" related to my app?

I've enabled keytips in my xaml and in the code-behind file I do this:
var keyGesture = new KeyGesture(Key.LeftAlt);
ribbon.SetValue(KeyTipService.AccessKeyProperty, keyGesture);

Bind class to RadGridView

Hi,

I am having trouble binding a class with 2 members to a RadGridView. The first member contains a dictionary to set the column header text and the second to fill the grid.

here is my sample project

cs

public Content()

{

// Get the labels from database

ContextSource.Labels = DictionaryFromDatabase();

// Get grid data from database

ContextSource.DataSrc = DataTableFromDatabase();

Listing.DataContext = ContextSource;

}

public class ContextSource

{

public DataTable DataSrc { get; set; }

public Dictionary<string, string> Labels { get; set; }

public ContextSource()

{

DataSrc = new DataTable();

Labels = new Dictionary<string, string>;

}

xaml

<telerik:RadGridView Margin="0"

AreRowDetailsFrozen="True"

AutoGenerateColumns="False"

CanUserFreezeColumns="False"

IsReadOnly="True"

ItemsSource="{Binding}"

SelectionMode="Single"

ShowInsertRow="False"

x:Name="Listing">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Header="{Binding Labels.[str_label0]}" DataMemberBinding="{Binding Path=DataSrc.[columnname0]}"/>

<telerik:GridViewDataColumn Header="{Binding Labels.[str_label1]}" DataMemberBinding="{Binding Path=DataSrc.[columnname1]}"/>

<telerik:GridViewDataColumn Header="{Binding Labels.[str_label2]}" DataMemberBinding="{Binding Path=DataSrc.[columnname2]}"/>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

When I set Listing.DataContext = ContextSource, it will only fill the header text property. The grid is not populated.

If I direct the Listing.DataContent directly to ContextSource.DataSrc then the grid is populated, but the headers are not set.

Listing.DataContext = ContextSource.DataSrc;

Any idea what I am doing wrong?

Kind regards,
Dennis

Multilevel list doesn't work correctly

Hi,

I use the last (Q3 2012) version of WPF controls. And I noticed that it can't get multilevel list (1.-1.1-1.1.1. for example) as it would be expected. The indent buttons behavior also doesn't work properly.

I would appreciate your advice or comments.

TabStripPlacement along side vertical align

Hi There,

I'm finding myself a bit stumped as to how to set the position of the tabs on the tab control if the placement is set to go along the left or right as per the attached image.

what it does right now is place the tabs from the bottom going up, but i would prefer to have them go from the top down...

is there a way to set this??

Thanks,
Nemanja

MergeField, CustomField update problem.

Hi,

The scenerio we are working on:

User A opens a template (docx) with RadRichTextBox.
Template has two MergeFields, "Subject" and "Signed".
User A updates the document and "Subject" MergeField is set to "User A's Subject".
Then User A saves the document as Docx and sends it to User B.
User B signs the document and "Signed" MergeField should be set to "Yes", but "Subject" MergeField shouldn't be updated.

The problem is, when User B opens the document, application does not have the User A's MergeFieldSource. So when application merge fields, it updates both "Subject" and "Signed" MergeFields.

I've tried couple of solutions, one with RadRichTextBox.MergeFieldToStringConverting event and one with inheriting MergeField.

In RadRichTextBox.MergeFieldToStringConverting solution, MergeFieldToStringConvertingEventArgs doesn't have the old/original value (before merging). If it was, I could pass the old value to the "Subject" MergeField when User B updates the document.

In CustomField implementation, I could have find a solution, if there were a functionality like; when protected override DocumentFragment GetResultFragment() method returns null, corresponding MergeField does not updates it's own value. But there is no such a functionality.

One another solution could be, enumerating the MergeFields in the document and update only the required ones. (This is possible in Office Word API). But I couldn't find a way to achieve the is with RadRichTextBox.

I've added a sample solution demonstrating the scenerio. (Using Telerik version 2012.3.1017.45)

Regards.

OLAP Data Mistake - measures in wrong columns randomly

Hi all,
I've tried PivotGrid control on OLAP to a my local cube on Analysis Service and I noticed that data was in wrong columns (randomly).
So I've tried the WPF demo on OLAP and same problem on data.
In attach you can find mistakes to reproduce it on the example.
I think that this is a bug (I know that this control is still beta...) and I've also noticed this mistake in silverlight control too.

Regards,
Davide
