MultiSelect ComboBox SelectionBoxTemplate binding issue

To illustrate MultiSelectComboBox, I am using some forum posted code.

for comboBox i am using

 

<telerik:RadComboBox SelectedIndex="0" x:Name="MembersComboBox"                                    
   ItemsSource="{Binding Members}"
   ItemTemplate="{StaticResource MultiSelectionComboBoxItemTemplate}"
   Visibility="{Binding CanViewOtherUserTrendingConfiguration}"
   SelectionBoxTemplate="{StaticResource MultiSelectionComboBoxSelectionBoxTemplate}"
   ToolTip="{Binding SelectedMembersText}"
   Width="150" Height="20" />
 as i am using MVVM pattern, above comboBox is contained in a user Control RadDocumentPane, and MainChartView userControl DataContext contains the ViewModel

<telerik:RadDocumentPane x:Class="MainChart.MainChartView"
...
>

 and datatemplate MultiSelectionComboBoxSelectionBoxTemplate is defined as

<DataTemplate x:Key="MultiSelectionComboBoxSelectionBoxTemplate">
 <TextBlock Text="{Binding RelativeSource={RelativeSource AncestorType={x:Type telerik:RadDocumentPane}, Mode=FindAncestor}, Path=DataContext.SelectedMembersText}" />
</DataTemplate>

 my question is when i check the checkboxes in the comboBox, it updates the tooltip of combo box, which is bind to viewModel's property SelectedMembersText, but it do not updates the textlbock inside the SelectionBoxTemplate. I am sure i am making some mistake in doing dataBinding. please help me fixing this issue, as i have already applied all possible ways(in my knowledge) of binding textBlock to the field.

 

 

 

 

 

 

 

 

 

1.<telerik:RadComboBox SelectedIndex="0" x:Name="MembersComboBox"                                    
2.                                     ItemsSource="{Binding Members}"

Keep TrackBall with logical focus

It's Telerik UI for WPF 2014.3.1202.40.

There is a  RadCartesianChart on screen. Once user clicks on outside region of the chart, the track ball disappears due to losing keyboard focus.

Is it possible to keep the track ball inside chart in this case? It still has logical focus anyway.

Thanks.

ExportToImage returnImageSize & dpi parameters

Say I have a Diagram that is 1920x1080.  I call ExportToImage with an enclosingBounds of (0, 0, 1920, 1080), a returnImageSize of (1920,1080), and a dpi of 384.

 I get an image that is 7680 x 4320.  Is that expected?  I am (perhaps naively) expecting to get an image that is 1920x1080, based on the value of the returnImageSize parameter.

 Thanks!

Behavior on HD displays

We are using the TextControl (http://www.textcontrol.com) in an WinForms application used by more then 40.000 employees.
Now we are migrating the application to WPF.
We realize a problem on HD Displays, where standard build-in dialogs like Search and Replace, Spellchecker, Font Format dialogs etc. are too small - maybe because standard MVC dialogs are still used.

 

What about the Telerik RichTextBox control?
Are all Build-In dialogs scaling on HD-Displays correctly?

Event MouseLeftButtonDown on GridViewHeaderCell

Hi,

 I tried to implement the MouseLeftButtonDown event and the CellDoubleClick event on a style:

<Style TargetType="{x:Type telerik:GridViewHeaderCell}">
            <Setter Property="Foreground" Value="White"/>
            <EventSetter Event="CellDoubleClick" Handler="SelectDeselectColumn"/>
            <EventSetter Event="MouseLeftButtonDown " Handler="SelectDeselectColumn2"/>
</Style>

 

The "CellDoubleClick" event works fine but the "MouseLeftButtonDown" event doesn't work! I tried each event alone in the style and the MouseLeftButtonDown never works!

In the class "GridViewHeaderCell" there is no event accessible for MouseLeftButtonDown, there is only a method called "OnMouseLeftButtonDown" My guess is that the event MouseLeftButtonDown (or MouseDown) is already handled somewhere else...

If I want to use the method "OnMouseLeftButtonDown" I have to create a new ​child class that the parent is "GridViewHeaderCell". But I don't know where to allocate the new class in the code. Is there a event like "AutogeneratingCoumn"?

Is there any other options possible to support the MouseLeftButtonDown event or a single click?

TimeRulerMonthViewGroupItem' TargetType does not match type of element 'TimeRulerGroupItem'

Serialize/Deserialize collections in SerializableGraphSourceBase

Following your Serialize a Databound Diagram article
I was wondering whether the RadDiagram Serialization/Deserialization system supports serialization of a collection within the GraphSource Nodes. In particular I am interested on using an ObservableCollection:

01.public class OrgItem : HierarchicalNodeViewModel
02.{
03.    public OrgItem()
04.    {
05.       this.MyCollection = new ObservableCollection<string>();
06.    }
07.    public ObservableCollection<string> MyCollection
08.    {
09.        get;
10.    }
11.…
12.…
13.…
14.}
15.private void BindGraphSource()
16.{
17.    int uniqueIdCounter = 0;
18.    GraphSource source = new GraphSource();
19.    OrgItem rootItem = new OrgItem()
20.    {
21.        Title = "CEO",
22.        Position = new Point(200, 20),
23.        Id = (uniqueIdCounter++).ToString()
24.    };
25.    rootItem.MyCollection.Add(new MyClass(“Test1”));
26.    rootItem.MyCollection.Add(new MyClass(“Test2”));
27.    source.AddNode(rootItem);
28.…
29.…
30.…
31.}
32.public class MyClass
33.{
34.    public MyClass(){};
35.    public MyClass(string myValue)
36.    {
37.        this.MyValue = myValue;
38.    }
39.    public string MyValue { get; set; }
40.}

 

Could I possibly Serialize/Deserialize the ObservableCollection in the OrgItem?

If that is possible how should i serialize/deserialize the collection in the GraphSource?

01.public class GraphSource : SerializableGraphSourceBase<OrgItem, OrgLink>
02.{
03.    public override string GetNodeUniqueId(OrgItem node)
04.    {
05.        return node.Id;
06.    }
07.    public override void SerializeNode(OrgItem node,
08.        Telerik.Windows.Diagrams.Core.SerializationInfo info)
09.    {
10.        base.SerializeNode(node, info);
11.        info["Title"] = node.Title;
12.    }
13.    public override OrgItem DeserializeNode(
14.        Telerik.Windows.Diagrams.Core.IShape shape,
15.        Telerik.Windows.Diagrams.Core.SerializationInfo info)
16.    {
17.        base.DeserializeNode(shape, info);
18.        if (info["Title"] != null)
19.        {
20.            return new OrgItem(info["Title"].ToString());
21.        }
22.        return null;
23.    }
24.}

 

Many thanks in advance,

Christos
