Custom TabItem template/Style in RadDocking DocumentHost

Hi,

I'm trying to have custom TabItems in a RadGroupPane in DocumentsHost. As I'm understand RadGroupPane items are rendered using TabItemPresenter (looked at RadGroupPane template) and are RadTabItem controls. Problem is that I can not get them to style.
A litle sample or idea how to set custom template for TabItem's in a RadGroupPane would be really good, as setting it in RadGroupPane resources as style with TargetType for RadTabItem seems don't work.

Thanks,
Saulius

Binding GridViewRow Visibility to Column IsVisible

Hello,

I have a RadGridView with a custom row style targeting GridViewRow (set using RowStyle property and defined in resource dictionary).
In that style I have a control template targeting GridViewRow.
In that template I have a couple of GridViewCells definitions.
Here is one of them, for example:

    
            <telerik:GridViewCell x:Name="theCell"  
        
                                                    BorderThickness="0" 
        
                                                    Foreground="{StaticResource ColorMessageText}" 
        
                                                    Value="{Binding Owner}" 
        
                                                    Margin="0,0,0,2" 
        
                                                    Content="Owner" 
        
                                                    Background="{x:Null}" 
        
                                                    BorderBrush="{x:Null}" 
        
                                                    FontSize="11"                                    
        
                                                    HorizontalAlignment="Left" 
        
                                                    HorizontalContentAlignment="Left" 
        
                                                    Width="90" 
        
                                                    Visibility="{Binding Column.IsVisible, Converter={StaticResource VisibilityOfBool}, ElementName=theCell}"/>

Now, what I am trying to accomplish is to bind the Visibility property to the column IsVisible property (using the required converter).
The problem is that both Column and DataColumn properties of the GridViewCell are unknown at run time (saw it using Snoop).

How do I make my GridViewCell hide when the matching column is hidden?

Thanks,
Gili

Problem with Binding

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 :

    
            <telerik:RadTabControl Name="RadTabControlAddress" SelectionChanged="RadTabControlAddress_SelectionChanged"> 
        
                                <telerik:RadTabControl.ItemContainerStyle> 
        
                                    <Style TargetType="{x:Type telerik:RadTabItem}"> 
        
                                        <Setter Property="ContentTemplate"> 
        
                                            <Setter.Value> 
        
                                                <DataTemplate> 
        
                                                    <Grid Name="Grid"> 
        
                                                        <Grid.ColumnDefinitions> 
        
                                                            <ColumnDefinition Width="100" /> 
        
                                                            <ColumnDefinition Width="*"/> 
        
                                                        </Grid.ColumnDefinitions> 
        
                                                        <Grid.RowDefinitions> 
        
                                                            <RowDefinition /> 
        
                                                        </Grid.RowDefinitions> 
        
                                                        <TextBlock Text="{Loc address1}" Grid.Row="0" Grid.Column="0"></TextBlock> 
        
                                                        <TextBox Grid.Row="0"  Grid.Column="1" Text="{Binding Adresse.Adresse1 }" Height="30" Margin="5"></TextBox> 
        
                                                    </Grid> 
        
                                                </DataTemplate> 
        
                                            </Setter.Value> 
        
                                        </Setter> 
        
                                    </Style> 
        
                                </telerik:RadTabControl.ItemContainerStyle> 
        
                            </telerik:RadTabControl>

(I deleted some field for a short version)

I have a simple RadButton with this event :

    
            private void AddAddressTab() 
        
                    { 
        
                        _model.AddAddress(); 
        
                        RadTabItem itemToAdd = new RadTabItem() 
        
                        { 
        
                            Header = "New Tab" 
        
                        }; 
        
                        RadTabControlAddress.Items.Add(itemToAdd); 
        
                        RadTabControlAddress.SelectedIndex = RadTabControlAddress.Items.Count - 1; 
        
                    }

The constructor in my XAML.cs is :

    
            public AjouterView(AjouterViewModel model) 
        
                    { 
        
                        InitializeComponent(); 
        
                        // Sauvegarde du model dans un attribut de la classe. 
        
                        _model = model; 
        
                        // On se sert de notre model en tant que DataContext. 
        
                        this.DataContext = model; 
        
                        //AddAddressTab(); 
        
                    }

In my Model I have two attribute :

    
            private IAdresse _adresse = null; 
        
                    public IAdresse Adresse 
        
                    { 
        
                        get { return _adresse; } 
        
                        set 
        
                        { 
        
                            _adresse = value; 
        
                            OnPropertyChanged("Adresse"); 
        
                        } 
        
                    }

My Model implement INotifyPropertyChanged - (And sorry for french name...)

The AddAddress() Method (in the model) :

    
            public void AddAddress() 
        
                    { 
        
                        IAdresse address = new Adresse("Just a test"); 
        
                        ListAdresse.Add(address); 
        
                        Adresse = address; 
        
                    }

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.

ATTACHED FILE :
You can download a demo here : Download

If you need more informations, please tell me.
Thank you in advance for your answer.

Regards,
G.B.

[EDIT] : Nobody shall have the beginning of solution ? I don't find how to fix this problem !

Scatter Plot Point Size

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

Image in DataTable databound to a GridView

Hi,

I have a grid that is bound to a DataTable. The structure of the DataTable varies at runtime so I cannot set the columns at design time (AutoGenerateColumns is set to true). When a column of the DataTable is of type System.Byte[] the grid shows "System.Byte[]" and I would like it to show an image instead. I am guessing I should be using a DataTemplate for this type but I am unsure of how to do this with the GridView, can you please help or point me to the relevant resource?

Cheers,

Jose

rowvalidating isvalid not preventing rowvalidated

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.

Automatic EditMode for a checkbox Column

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
