It is possible to restore selected value in the view model i'm trying 
something like this but combobox do not changed to the correct item you see last selected from the use 

<telerik:RadComboBox ItemsSource="{Binding Tests}" Width="150" Height="25"
                             SelectedValuePath="Id">
            <telerik:RadComboBox.SelectedValue>
                <Binding Path="SelectedTestId" Mode="TwoWay" BindsDirectlyToSource="True" UpdateSourceTrigger="PropertyChanged"/>
            </telerik:RadComboBox.SelectedValue>
            <telerik:RadComboBox.ItemTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Name}"/>
                </DataTemplate>
            </telerik:RadComboBox.ItemTemplate>
        </telerik:RadComboBox>

     public int SelectedTestId
        {
            get
            {
                return selectedTestId;
            }
            set
            {
                OldSelectionTestId = selectedTestId;

                SetProperty(ref selectedTestId, value);

                if (OldSelectionTestId > 20 && SelectedTestId == 20)
                {
                    Debug.WriteLine($"oldSelectionTestId = {OldSelectionTestId}");
                    Debug.WriteLine($"SelectedTestId = {SelectedTestId}");
                    HasError = true;
                }
            }
        }

Observe any other edit control in existence. When you hold the arrow key down to move the caret through text, it stays visible and does not blink until a brief pause after you take your finger off. Unfortunately in RadRichTextBox it keeps blinking so you lose track of where it is. This is very frustrating when you are navigating long documents because it can even prevent you from seeing the caret moving to a different line. Or hold down any character key and the caret disappears completely, giving you one less cue that something is haywire if your arm is leaning on the keyboard.

This isn't a bug per se but it isn't a minor usability issue either. What has to happen is an idle timer begins *immediately after* a key down, during which no blinking can begin. If a key down happens again, the timer resets. If the timer expires, then that starts the caret show timer.

I am dynamically generating tabs based on databinding.  After I change the datacontext I get the tabs I expect but none of the tabs are selected. I am expecting a tab (likely the first one) to be selected when this happens.   I should mention I am using an older version R2 2017

In the following example of MVVM application i tried to bind AccessKey to ribbon items to ribbon items. Unfortunatly the user have to navigate through ribbon and cannot use hotkey direcctly. The  user have to press hotkey for tab to can use Hotkey for button. Which is just a little bit unpractical if the user wants to use to acces functionality direct, or to inform which hotkey is for which button.

In your example for RibbonView(wpf) called "Office" ,if I press Alt  and cann see all ToolTips for. Do I miss some think in my exampple?

Hi, 

Recently I have changed my WPF application Root window from Window to RadRibbonWindow and this RadRibbonwindow is not loading application Icon from embedded resources. What do I need to do, to make RabRibbonWindow load an icon "ico" from resources automatically? My all other Windows are loading Icon from embedded resources automatically.

Hello,

it seems the radtimepicker is always using the US Date format. Why is it not using the the host machine localisation ? The problem is now I can not easily convert to date time (even though only the time portion is relevant ) . Please see attached screen shot. Here in South Africa our machines are set to DD/M/YYYY plus time but the timepicker is return the full date in us format M/DD/YYYY plus time.

Hello,

i am upgrading an old project that uses .NET 3.5 and Telerik UI for WPF 2012.x to the latest .NET and Telerik UI versions. I have a GridView whose ItemsSource is bound to a RadObservableCollection provided by a MVVM viewmodel. As i rememder i used this collection because of the RemoveRange-method which had some performance benefits compared to the ObservableCollection.Remove-method (suspending the collectionchanged-events).

But now i have the problem, that, if a least one column is sorted, not the correct rows are removed. The rows removed are those, that are in the place of the rows i want to delete if the table were unsorted. Deleting from an unsorted GridView works fine. If i use the Remove-method in a loop instead of the RemoveRange deleting works as expected in sorted and unsorted GridViews.

Is it not longer recommended to use the RadObservableCollection as an ItemsSource for a GridView or is it a bug?
