Multiple Heading Rows

Hi.

I would like to have more than 1 row as a heading to my grid.
I would like to have a heading that is applicable to a couple of columns, with each underlying column still having its own heading.

It should be simular to the formatting that you can do in excel, when you merge a couple of columns into 1 column, and still have columns underneath it, example
------------------------------------
| Data Group |
------------------------------------
|Column1|Column2|Column3|
------------------------------------

I have a project where I need to add columns to my radgrid in code, so please help with a WPF C# example.

Thanks.

Close tabs - RadTabControl + Prism

Hello,

I'm a beginner in WPF and I need your help to do something.

I want to add a system to close tabs for users. But I can't do it !
I found a video here : http://tv.telerik.com/wpf/prism/introduction-prism-with-radcontrols-wpf and I use the same thing for RadTabControl. So I'm using MS Composite Application Guidance and the RegionManager.

So I have this code id my main project :

    
            <telerik:RadTabControl Name="tabControlClient" DockPanel.Dock="Right" cal:RegionManager.RegionName="MainRegion" Margin="10 0 10 10" ScrollMode="Viewport" DropDownDisplayMode="Visible" DisplayMemberPath="Content"> 
        
                        <telerik:RadTabControl.ItemContainerStyle> 
        
                           <Style TargetType="{x:Type telerik:RadTabItem}"> 
        
                                <Setter Property="Header" Value="{Binding DataContext.HeaderInfo}" /> 
        
                                <Setter Property="Height" Value="25" /> 
        
                                <Setter Property="IsSelected" Value="True" /> 
        
                            </Style> 
        
                        </telerik:RadTabControl.ItemContainerStyle> 
        
            </telerik:RadTabControl>

In my Module Project I copy the code on the video :

    
            public String HeaderInfo 
        
            { 
        
                 get { return "Labs Module"; } 
        
            } 
        
            #region INotifyPropertyChanged Membres 
        
            public event PropertyChangedEventHandler PropertyChanged; 
        
            protected void OnPropertyChanged(String propertyName) 
        
            { 
        
                 if (this.PropertyChanged != null) 
        
                 { 
        
                      this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); 
        
                 } 
        
            }

It work ! But now I want to add a close system. So I search the solution in this forum and I found this : How to Add Close Button to the Tab Headers
So I complete my code in my main project like this :

    
            <telerik:RadTabControl Name="tabControlClient" DockPanel.Dock="Right" cal:RegionManager.RegionName="MainRegion" Margin="10 0 10 10" ScrollMode="Viewport" DropDownDisplayMode="Visible" DisplayMemberPath="Content"> 
        
                        <telerik:RadTabControl.ItemContainerStyle> 
        
                           <Style TargetType="{x:Type telerik:RadTabItem}"> 
        
                                <Setter Property="Header" Value="{Binding DataContext.HeaderInfo}" /> 
        
                                <Setter Property="HeaderTemplate"> 
        
                                    <Setter.Value> 
        
                                        <DataTemplate> 
        
                                            <Grid> 
        
                                                <TextBlock Text="{Binding Header}"></TextBlock> 
        
                                                <Button Grid.Column="1" Margin="3 0 0 0" Content="x" Width="16" 
        
                                                   Height="16" HorizontalAlignment="right"/> 
        
                                            </Grid> 
        
                                        </DataTemplate> 
        
                                    </Setter.Value> 
        
                                </Setter> 
        
                                <Setter Property="Height" Value="25" /> 
        
                                <Setter Property="IsSelected" Value="True" /> 
        
                            </Style> 
        
                        </telerik:RadTabControl.ItemContainerStyle> 
        
                    </telerik:RadTabControl>

But only close button appear and not the header text.
So how I can use this two solution to have "Header text + close button" please ?

If you need more informations or others, tell me.

Thank you in advance.
Best Regards

Chart Series Opacity read only

We have noticed with your chart control that when we set it so that the point labels are showing it makes the opacity of the series definition read only. Is there a way to disable this behavior or work around it so that we can change the opacity in this case? Currently we turn the opacity to 50% for all other series when the user hover’s the mouse over one of the series items in the legend. If the point labels are on and the opacity locked we are unable to do this. Any help on this matter would be greatly appreciated.

Thanks in advance

Grid does not leave edit mode

Hello,

It seems that if I set the ValidationMode and add a RowEditEnded handler on my grid either declaratively or programmatically, the grid does not leave edit mode when the Enter key is pressed. The only way I can get it out of edit mode it to click on another row. If I do not add a RowEditEnded event handler, then pressing Enter works as expected.

Am I doing something wrong? Missing something?

Update: It seems to be related to setting ValidationMode="Row". With this setting, even if I have no RowEditEnded event handler, the cell will stay in edit mode.

Thanks,
Mark
