Hi.
When changing visual style not the first time, but the second time, the application always chrashes. I change the styles like this:

this

.RadRibbonBar.SetValue(StyleManager.ThemeProperty, new Windows7Theme());

this.RadPaneGroup.SetValue(StyleManager.ThemeProperty, new Windows7Theme());

this.RetrivalDataGrid.SetValue(StyleManager.ThemeProperty, new Windows7Theme());

It does not matter which style I change to. It always works the first time and always chrases the second time.

The application error message is like this:

An unhandled exception of type 'System.ArgumentOutOfRangeException' occurred in PresentationCore.dll

Additional information: Specified argument was out of the range of valid values.

Anyone know what this problem is?

regards
Kjetil

RadRibbonWindow is flickering while resizing

heya,

i am porting an existing project to telerik and since i changed my window to derive from RadRibbonWindow i experience flickerings when i resize the window (no code or eventhandler is handling the resizing). additionally i specified

ResizeMode="CanResizeWithGrip"

on the window.

most of the time the border and title-bar is flickering, sometimes the whole window.
on my tryout with another wpf component suite just the areas flicker sometimes, where i created "new space" through resizing.

is there a way to prevent this?

thx

EDIT: this is especially nasty, because the flickering area is black :(
EDIT2: after a sleep of my notebook most of the drawing-area of the program was now black. unfortunately i didnt do a screenshot. .. :(

Binding column with Integer

Hello,

I need help (again) with the RadGridview please.

PROBLEM :
I use a RadGridView to display some informations. And one column have a Binding with an Integer attribute.
When I edit a row, and put a value which is not a number in the cell, my application crash (normal).

I tried to use GridViewMaskedTextBoxColumn with MaskType="Numeric" but it doesn't work or I does not succeed in using it.

CODE :
I have a gridview with an ObservableCollection as ItemSource :

    
                    private ObservableCollection<IRoleUtilisateur> _userRole; 
        
                    public ObservableCollection<IRoleUtilisateur> ListUserRole 
        
                    { 
        
                        get { return _userRole; } 
        
                        set 
        
                        { 
        
                            _userRole = value; 
        
                            OnPropertyChanged("ListUserRole"); 
        
                        } 
        
                    }

In my RoleUtilisateur class (implements IRoleUtilisateur) I have an Integer :

    
                    private int _rang; 
        
                    public int Rang 
        
                    { 
        
                        get 
        
                        { 
        
                            return _rang; 
        
                        } 
        
                        set 
        
                        { 
        
                            _rang = value; 
        
                        } 
        
                    }

XAML :

    
            <telerik:RadGridView.Columns> 
        
                            <telerik:GridViewDataColumn Header="{Loc rank}" DataMemberBinding="{Binding Rang}" /> 
        
            </telerik:RadGridView.Columns>

(I deleted all columns except the one with the Binding with Integer attribute)

INFOS :
Visual Studio 2008
.NET Framework 3.5 SP1
Telerik 2010.1.603

How can I do to avoid crashing please ?

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

Regards,
G.B.

Time counter inside a RadGridView

Hi,
I'm trying to implement a monitoring gridview that have a column of a time counter that increments in each second.
For now the only solution that i came up with is to do a DispatcherTimer initiating foreach that increment each object and then rebind the grid, which of course is an awful performance hit.
Any suggestions?

Several Issues with TileView Control

Hello telerik,

I am going to use RadTileView Control in my appliaction with XML-DataBinding.
But I have some problems:

1.) I have tried out to manage to current State of the control in the code-behind file. Here in forum I found out that I have to use following call ->
RadTileViewItem radTileItem = settingRadTileView.ItemContainerGenerator.ContainerFromItem(buissinesObject) as RadTileViewItem;

I do get a reference to each RaTileViewItem in the collection but do not get a reference to the RadFluidContentControl, if I do this call
RadFluidContentControl fluidControl = item.Content as RadFluidContentControl.
While debugging I see at quickwatch that the content of the RadTileViewItem is a XmlElement.

What should I do to get / wrap an XMLElement to RadFluidContentControl ?

2.) Another issue is, when I am setting the MinimizedHeight / MinimizedWidth - Property of each RadTileViewItem in the code -behind file e.g in the SizeChanged-Handler, I have always to click at the TileView - Control in order to update the current view then after loading TileViewItems allocate whole space the is available. Only after a e.g Click on TileView RadTileViewItems change height and width setted in the code-behind file.

How can achieve a refresh on TileViewControl in the code-behind file whithout cklicking / user interaction ?

3.) I am setting the MinimizedHeight / MinimizedWidth - Property of each Item in the code-behind file in SizeChanged-Handler depending on the ActualHeight of the grid, but if I am setting my desktop resolution to 800x600 pixel some minimized items disappear and I have only 7. I read that at the moment there is no scrollerView for minimized Items, does it mean that at the moment I can just show a few items ?

4.) Can just header be visible in in minimized state without any content?

5.) And at least, how can I change the size of the content e.g of the large content dynamically ? If I change the resolution of the desktop some visible area of the large content disappear, although the snaptodevicepixel is checked an the size of the border in the LargeContent is setted to auto ? Have I to change the width and heigt ot the content control itself dinamically ?

Thank you.

Here is my code:

    
                <Grid>               
        
                    <telerikNavigation:RadTileView x:Name="settingRadTileView"
