RadRibbonBar

Hi,

I would first of all like to say 2010 Q1 looks great!! Nice work.

Secondly, I am developing with the RadRibbonBar, I know there were a few issues when using it when minimised, such as the Ribbon not minimising itself again when lost focus. This is now fixed, which is great, however the Ribbon does not minimise when button has been clicked.

I have a Ribbon bar with buttons which when clicked display open a tab just below the ribbon, the tab opens fine but the Ribbon does not minimise. Is this by design?

Also, the first tab is always selected on load, I have all my RadRibbonTabs.IsSelected = False, once a Tab has been clicked and minimised, no tabs are selected. I have also tried looping through the RadRibbonBar.Items collection and setting RadRibbonBar.SelectedTab=null but there is tab always selected.

One other issue I came across was when I dragged my application and placed it across my two screen and clicked on a Tab, the ribbon tab opened off screen to the left or the right, instead of directly under the tab header where it should open.

One other question, has integration of the RibbonBar into the main application window been implemented in thithe 2010 Q1 release?

Thanks again!

A Marshall

RadRibbonButton.Text gets cropped

Hi guys,

I think i found a bug in the TextProperty of the RadRibbonButton. When i set text that contains whitespaces, the text shown in the ribbon is cropped from the first whitespace on. Is this a wanted behavior or is it really a bug ?

Thanks in advance.

TriState and Binding

Hi,

I am binding a treeview to a collection of objects. This is for use in a user/group permissions for my application.
The treeview is displaying up to four levels

The tree binds to a property on the object of type bool? , to achieve the tri state.

This is the ItemContainerStyle for the treeview

    
             <Style x:Key="GroupSecurityRadTreeStyle" TargetType="telerik:RadTreeViewItem">  
        
                <Setter Property="CheckState" Value="{Binding IsGroupActivated,Mode=TwoWay, Converter={StaticResource CheckStateConverter}}"/>  
        
                <Setter Property="IsExpanded" Value="True"/>          
        
             </Style>

The value converter;

    
               public class CheckStateConverter : IValueConverter  
        
                {  
        
                    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)  
        
                    {              
        
                        bool? result = (bool?)value;  
        
                        if (result.HasValue)  
        
                        {  
        
                            return result.Value ? ToggleState.On : ToggleState.Off;  
        
                        }  
        
                        else 
        
                        {  
        
                            ToggleState o = ToggleState.Indeterminate;  
        
                            return o;  
        
                        }  
        
                    }  
        
                    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)  
        
                    {  
        
                        ToggleState state = (ToggleState)value;  
        
                        return state == ToggleState.On ? true : false;  
        
                    }  
        
                }

The binding to the tree works perfectly, the problem I am having is when an treeviewitem is in the indeterminate state on the tree view.

When an item has been put in the indeteminate state, the (ToggleState)value in the ConvertBack method is set to 'Off', I would have expected this to be set to 'Indeterminate'.

I know the ConvertBack method doesn't actually deal with the indeterminate state, but that is due to me not being able to get it.

Is there something I am doing wrong?

Thanks,

A Marshall

Hi, Telerik.

I want to set a toolbar in a RadDocumentPane as the picture showing.

I try to use the RadToolBar control instead, but it looks a little ugly.

I wonder if there is any other way to achieve it.

Wish your help!
