How to switch Grid View for View Mode in MVVM patter

Hello,

I am using RadGridView for WPF. After changing cell's value in the grid and selecting another control (for example dropdown list or button on the same window) row is still in editable mode and changes in the cell is not applyed to corresponding model (I am using default binding). How could I force Grid to switch from Edit mode back to view mode on losing focus or when some command is executed (for example, command that is binded to the button).

Thanks,
Alexey Smirnov

RadRibbonWindow title

Hi,

I am using RadRibbonView(with title) within a RadRibbonWindow. The title shows up in the center on the top of the window. I want to display it right next to the Window Icon. I tried modifying the template for RadRibbonView but I couldn't figure this out.

Any suggestions about how I can achieve this?

Thanks,
Nav

RadComboBox and Command Binding

What is the use of Command when using RadComboBox, when it does not seem to fire when the selection inside the RadComboBox changes?

When I hook the command, it seems to fire once, when the command is initialized, then it never fires.

Allow comma and dot as decimal separator in GridViewDataColumn

Hi,

I would like to allow either comma and dot as decimal separator in GridViewDataColumn.

<telerik:GridViewDataColumn Header="Qté" DataMemberBinding="{Binding Quantity, Mode=TwoWay}"/>

Where Quantity is :

private double _quantity;

public double Quantity

{

get { return OrderUnit == PackagingUnit.Kilogram ? Math.Round(_quantity, 3) : Math.Round(_quantity, 0); }

set

{

if (_quantity == value) return;

_quantity = value;

RaisePropertyChanged(ReflectionUtility.GetPropertyName(() => Quantity));

Refresh();

}

The ViewModel set those parameters in constructor :

var culture = new CultureInfo("fr-FR", false);

culture.NumberFormat.CurrencyDecimalSeparator = ".";

culture.NumberFormat.NumberDecimalSeparator = ".";

culture.NumberFormat.PercentDecimalSeparator = ".";

culture.Parent.NumberFormat.CurrencyDecimalSeparator = ".";

culture.Parent.NumberFormat.NumberDecimalSeparator = ".";

culture.Parent.NumberFormat.PercentDecimalSeparator = ".";

LocalizationManager.DefaultCulture = culture;

Dispatcher.CurrentDispatcher.Thread.CurrentCulture = culture;

Dispatcher.CurrentDispatcher.Thread.CurrentUICulture = culture;

Thread.CurrentThread.CurrentCulture = culture;

Thread.CurrentThread.CurrentUICulture = culture;

Result :

When the cell isn't in EditMode, if quantity is 4,268, the cell displays 4.27 : it's why I want.

But when the cell is in EditMode: if user write 4.58 for example, the value isn't recognize as a valid double and is converted back. When writting 4,58, the value is successfully recognized.

Thanks

Caret doesn't show upon start when RichTextBox is empty

When the RichTextBox is empty upon start, the caret does not show when I click on the control. However, when I type into the richtextbox, the text shows and the caret appears as well. I tried setting the caretposition of the document in the constructor, but that doesn't work. How do I make the caret show upon start?

Below is the xaml of the usercontrol.

<UserControl x:Class="CommonControl.HtmlEditor"

xmlns:telerikHtmlMain="clr-namespace:Telerik.Windows.Documents.FormatProviders.Html;assembly=Telerik.Windows.Documents"
