Hello,

I've already created a topic in this forum, and I need your help once again.
I work with the same configuration (it's the same application) : Telerik + MS Prism
Link : Close tabs - RadTabControl + Prism

I have a problem with the Binding and RadTabControl.
I have a button to add a RadTabItem in my RadTabControl, and the content of the RadTabItem work with a ContentTemplate.
The content is a form with some TextBox and each textbox has a Binding with an Object in my Model.

CODE :
So, here the XAML code of my RadTabControl :
(I deleted some field for a short version)

I have a simple RadButton with this event :

The constructor in my XAML.cs is :

In my Model I have two attribute :
My Model implement INotifyPropertyChanged - (And sorry for french name...)

The AddAddress() Method (in the model) :

I not include the system to change the address when we select an other Tab.

PROBLEM :
The first time we add an address (add a Tab in the TabControl), the binding doesn't work. I need to add two address for work. I don't find why ! The binding work only if I click the Button (to add an other address) if there is already a Tab in the TabControl.

Thank you in advance for your answer.

When I try to change the point size on a scatter plot, it doesn't increase in size, it's as if the container is fixed at a size and the point get clipped (so when I draw a circle point of point size 20, i see only a quarter of the circle appear on the graph).

here is my code i'm using to adjust the size:

DataSeries series = new DataSeries();
            ScatterSeriesDefinition l = new ScatterSeriesDefinition();
            l.Appearance.Fill = Brushes.DeepPink;
            l.Appearance.Stroke = Brushes.Black;
            l.PointSize = 20;
            series.Definition = l;

Appreciate your thoughts,
Nelson

Hi,

Hi All

I am using the WPF 2010 Q1 controls and as per the documentation here: http://www.telerik.com/help/wpf/gridview-events-validation.html

I am calling the rowisvalidating event and on a condition setting e.IsValid = false; But even when this is set to false, the rowisvalidated event is still fired. I thought that this would not be the case.

Hi,

I'm using RadControls for WPF 2010 Q1 (V2010.1.528.35). I have to customize the RadGridView according the following points :

• the grid needs to define a first column that is a checkbox column allowing to select/deselect rows
• this column is databound (2way) to a boolean property (IsSelected) of an object.
• the column must be always in edit mode. The user needs to be allowed to check directly the checkboxes without a previous click/double click that put the cells in editmode.

The first 2 points are done without any problem. For the third, I've tried differents ways to achieve this goal but without success :/

Can someone provide me a little help on this point ?

Greets,

Thomas

I really need some help on this!! :)

I'm unable to get rid of the background of the mouseovervisual. I've followed the example provided in the project here with no luck http://www.telerik.com/community/forums/wpf/panelbar/turn-off-mouse-over-effect-in-item-panel.aspx.

The problem is that when the panels are expanded, the mouseovervisual effect of the default orange background still appears on hover, even when applying the PanelBarItemSecondLevelTemplateStyle to the RadPanelBarItem.

The xaml:

    <Grid x:Name="MainContent" Margin="0,2,2,0">
        <Border BorderBrush="#FF336687" BorderThickness="1" CornerRadius="4" Margin="0" Width="Auto" Height="Auto">

            <telerikNavigation:RadPanelBar x:Name="PresentationPanel" Template="{DynamicResource PresentationPanelBar}" Background="Transparent"
                                           dragDrop:RadDragAndDropManager.AllowDrop="True" Orientation="Vertical" ExpandMode="Multiple">
                <telerikNavigation:RadPanelBarItem Name="DetailsPanel" IsExpanded="{Binding IsDetailsExpanded}" Template="{DynamicResource PanelBarItemSecondLevelTemplateStyle}">
                    <telerikNavigation:RadPanelBarItem.Header>
                        <ContentControl Cursor="Hand">
                            <TextBlock Text="Details" Foreground="#FFFFFF" Margin="5 4 5 5"/>
                        </ContentControl>
                    </telerikNavigation:RadPanelBarItem.Header>
                    <local:DraggableListBox x:Name="DetailDraggableListBox" ItemsSource="{Binding AvailableDetails}"
                                            ItemTemplate="{StaticResource Test}"
                                            ItemsPanel="{StaticResource DefaultWorkspacePanelTemplate}"
                                            Background="Transparent"
                                            BorderThickness="0" ScrollViewer.HorizontalScrollBarVisibility="Disabled">
                    </local:DraggableListBox>
                </telerikNavigation:RadPanelBarItem>

                <telerikNavigation:RadPanelBarItem Name="TopicsPanel" IsExpanded="{Binding IsTopicsExpanded}" Template="{DynamicResource PanelBarItemSecondLevelTemplateStyle}">
                    <telerikNavigation:RadPanelBarItem.Header>
                        <ContentControl Cursor="Hand">
                            <TextBlock Text="Topics" Foreground="#FFFFFF" Name="txtTopicsHeader" Margin="5 4 5 5" />
                        </ContentControl>
                    </telerikNavigation:RadPanelBarItem.Header>
                    <local:DraggableListBox ItemsSource="{Binding TopicsForSelectedDetail}"
                                            ItemTemplate="{StaticResource Test}"
                                            ItemsPanel="{StaticResource DefaultWorkspacePanelTemplate}"
                                            Background="Transparent"
                                            BorderThickness="0" ScrollViewer.HorizontalScrollBarVisibility="Disabled">
                    </local:DraggableListBox>
                </telerikNavigation:RadPanelBarItem>
                <telerikNavigation:RadPanelBarItem Name="ContentPanel" IsExpanded="{Binding IsContentExpanded}" Template="{DynamicResource PanelBarItemSecondLevelTemplateStyle}">
                    <telerikNavigation:RadPanelBarItem.Header>
                        <ContentControl Cursor="Hand">
                            <TextBlock Text="Content" Foreground="#FFFFFF" Margin="5 4 5 5"/>
                        </ContentControl>
                    </telerikNavigation:RadPanelBarItem.Header>
                    <local:DraggableListBox ItemsSource="{Binding ContentForSelectedTopic}"
                                            ItemTemplate="{StaticResource Test}"
                                            ItemsPanel="{StaticResource DefaultWorkspacePanelTemplate}"
                                            Background="Transparent"
                                            BorderThickness="0" ScrollViewer.HorizontalScrollBarVisibility="Disabled">
                    </local:DraggableListBox>

                </telerikNavigation:RadPanelBarItem>

I am currently testing Telerik, and testing for the charting at the moment, however I seem to be unable to render 3d charts.

Assume I have a XAML document, with one RadChart element, named w_Chart. The following works as expected:

However, if I change AreaSeriesDefinition to Area3DSeriesDefinition, it crashes (IntelliTrace picks up a lot of null reference exceptions). The same is true of Bar -> Bar3d.

What is required to get 3d charting to work?

[Edit: ] It also crashes when I attach a camera.
