Hi There

I cant find any examples of how to set focus on a selected row.

Say I have a grid with 5000 records and in code I set the selecteditem. I then want the grid to show that item in focus on the screen (scroll to where that item is located).

How would this be possible?

Regards

Nick

Error when changing visual style

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. .. :(

[Solved] 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?

Can any one tell me hoe to restrict the drag and drop of the radtreeviewitems. (ie., it should not allow to be dropped as an child of another item). The drop should happen only before or after rootnodes.

TIA
