Hello support,

how can I get the selected cell within a TreeListView?

With TreeListView.SelectedItem I get the whole row (mark yellow in attached image), but how can I get the column of the selected cell (see image)?

I need this information to display a summary of the selected column.

 Thanks in advance

I have a custom QueryProvider implementation, with which I'm able to intercept Linq queries on a custom collection implementation and send this query to an API, implementing server-side filtering of data; I have RadGridViews working this way.

I was trying to achieve this with the RadAutoCompleteBox, while retaining the option to keep free text input, but it seems the ToList of ItemsSource is forcefully called *before* the filtering is done (enforcing client side filtering);

I've looked at the IFilteringBehavior interface, but it seems it gets an IList (which my collection doesn't implement, will ToList be called as well?) as a parameter; is there any way to implement this? I'm going to give IFilteringBehavior a chance, just want to be sure if there's anything better or if it doesn't work.

Hi there!

May you help me  about some telerik component/tool to work with positional files(Files that have field determined by inicial e final positions), something like excel tool (attached picture)

A component like a track bar where user can select several positions in a file determining a initial and final position of each field

Hello,

is there a way to place the tabs at the bottom of the document host? Here's my XAML. I'm not sure how to move them to the bottom.

Thanks,

Hi @All,

as far as I could see from the samples the Telerik UI for WPF components are mainly targeted towards an WCF-based backend service.

Is it easily possible to use a ASP.NET MVC WebAPI REST-service as a backend from a WPF Desktop application?

I'd like to build a SPA web app that uses MCV Web API as a backend. There is also a mobile app that uses the same REST-services.  But for some functions the browser is not a good ​platform and I'd like to give our users a "fat-client" (e.g. for report design, Office ole-automation). But I'd also like to use the same backend for both and I wouldn't like to build a new WCF-backend only for the desktop clients. Of course the WPF application should be full-featured (data grids, data filters) and I don't want to re-invent the wheel.

Are there any samples available for this scenario?

Kind regards

Gerold

Hello,

I'm writing a custom filter for a RadGridView and it works almost perfectly.

The only problem I have is that I am calling GetDistinctValues(ColumnToPrepare, True, Nil) on the IFilterDescriptor.Prepare method, in order to know which values I must display. During the call to GetDistinctValues, the GridView runtime calls the filter expression to filter the items.

From the documentation, it seems that this overload of GetDistinctValues should filter the items with other filters, but not the one on the current column. Is there an error in the documentation or an error in the code?

Note that I've currently curcumvent the problem by using a field to "disable" my filter in this case, but it is not a "clean" solution.

I have experienced an error in RadCalendar where the years displayed are wrong, after navigating outwards from the current month to the current year and then again to the current decade and out to the current century and moving back and forth. The Text property is not dislaying the CalendarButtonContent Date. Why this happens is not something I am sure, but I set the Culture of the calendar to Norwegian bokmål (nb-no). Let me show you how at least I managed to get the RadCalendar working again. 

First off in your resource file, define a style for the RadCalendar: 

<Style TargetType="{x:Type telerikInput:RadCalendar}"><Setter Property="FontFamily" Value="Segoe UI" /><Setter Property="FontSize" Value="9" />       <EventSetter Event="Loaded" Handler="RadCalendar_Loaded" /></Style>

The style got no key, so it will be the implicit style of any RadCalendar control/instance in your app. Ok, so now let's look at the EventSetter. 


 public void RadCalendar_Loaded(object sender, EventArgs e)         {             try             {                 var radCalendar = sender as RadCalendar;                 if (radCalendar != null)                 {                     radCalendar.Culture = new CultureInfo("nb-NO");                     radCalendar.DisplayModeChanged += radCalendar_DisplayModeChanged;                     radCalendar.DisplayDateChanged += radCalendar_DisplayDateChanged;                 }             }             catch (Exception) { }         }         void radCalendar_DisplayDateChanged(object sender, Telerik.Windows.Controls.Calendar.CalendarDateChangedEventArgs e)         {             AdjustRadCalendarDisplayYearsFix(sender);         }         void radCalendar_DisplayModeChanged(object sender, Telerik.Windows.Controls.Calendar.CalendarModeChangedEventArgs e)         {             AdjustRadCalendarDisplayYearsFix(sender);         }         private static void AdjustRadCalendarDisplayYearsFix(object sender)         {             //TA 11.11.2015: Resolution of the calendar bug observed when navigating years and decades in the calendar              var calendar = sender as RadCalendar;             if (calendar == null)                 return;             DispatcherUtil.DelayedInvokeAction(() =>             {                 var calendarButtons = calendar.ChildrenOfType<CalendarButton>().ToList();                 if (calendarButtons.Any())                 {                     foreach (var c in calendarButtons.Where(cb => cb.ButtonType == CalendarButtonType.Year || cb.ButtonType == CalendarButtonType.Decade))                     {                         try                         {                              if (c.DataContext is CalendarButtonContent)                             {                                 var cbc = c.DataContext as CalendarButtonContent;                                 var tb = c.FindChildByType<TextBlock>();                                 if (tb != null)                                     tb.Text = cbc.ButtonType == CalendarButtonType.Year ? cbc.Date.ToString("yyyy") :                                          cbc.Date.ToString("yyyy") + "-" + cbc.Date.AddYears(10).ToString("yy");                             }                         }                         catch (Exception err)                         {                             Debug.WriteLine(err.Message);                         }                     }                 }             }, 500);         }

Ok, so we also use something called DelayedInvokeAction here:

      /// <summary>         /// Executes an action passed into this method by a timeout measured in milliseconds         /// </summary>         /// <param name="executeAction">Action to execute</param>         /// <param name="timeOut">The timeout to wait before executing (in milliseconds)</param>         /// <param name="priority"></param>         ///    /// <param name="keyToken">A key token to identity the switch (basic grouing). Will be used as a tag on the DispatcherTimer</param>         public static bool DelayedInvokeAction(Action executeAction, int timeOut, DispatcherPriority priority = DispatcherPriority.Background, Guid? keyToken = null)         {             var delayedAction = new DelayedAction(executeAction, timeOut, keyToken);             ActionsRegistered.Add(delayedAction);             DispatcherTimer dtimer = new DispatcherTimer(priority);             dtimer.Interval += new TimeSpan(0, 0, 0, 0, timeOut);             dtimer.Tag = delayedAction.ExecuteGuid;             dtimer.Tick += DelayedInvokeTimerTick;             dtimer.IsEnabled = true;             dtimer.Start();             return true;         }
public class DelayedAction     {         private readonly Action actionToExecute;         private readonly int timeOut;         private readonly Guid executeGuid;         public Action ActionToExecute         {             get { return actionToExecute; }         }         public int TimeOut         {             get { return timeOut; }         }         public Guid ExecuteGuid         {             get { return executeGuid; }         }         public DelayedAction(Action actionToExecute, int timeOut, Guid? keytoken)         {             this.actionToExecute = actionToExecute;             this.timeOut = timeOut;             this.executeGuid = keytoken ?? Guid.NewGuid();         }     }


Hope this helps!
