When using HeaderTextWrapping and FilteringMode.FilterRow the headers does not look consistent. The filter-rows should take up the same height on all columns. This looks the same for several styles.

Solution: The GridViewHeaderRowTemplate contains a Grid named PART_OuterGrid, and it's second RowDefinition should have Auto-height.

For what it worth, playing around with the reminders example I found that it wouldn't open the appointment for edition when the "Open Item"  button is clicked.

I checked the git repository to see if this is already addressed, but the last update to this files is about 4 years old, so here is the trick:

It turns out that at the time where the scheduleview reference is passed to the ReminderViewModel constructor (via the ViewModel class constructor), it is null.

So I added a ScheduleView property to ViewModel as a fachade for the reminder's view model property:

        public RadScheduleView ScheduleView
        {
            get { return reminderViewModel.ScheduleView; }
            set { reminderViewModel.ScheduleView = value; }
        }

and set it again once the IntializeComponent() method is called in the Example window's constructor:

        public Example()
        {
            viewModel = new ViewModel(this.scheduleView);
            this.DataContext = viewModel;
            InitializeComponent();
            viewModel.ScheduleView = this.scheduleView;
        }

And presto! Now it works as expected.

Best regards.

RadRichTextBox control is really a wonderful control, but their are problems when writing in Arabic (right to left). I could override those problems unless for a major problem; where if the user wanted to enclose an Arabic word within brackets, then the direction and position of brackets change, as shown in the attached image.

How to correct this abnormal behavior???!

Any help please !!!

thank you ...

I have a case where the event handler that handles AppointmentSaving is invoked twice, but only every other time. It goes like this:

1) Find a calendar event

2) Drag the edge of the event to make it wider

3) Find a second event, and drag *that* event wider. AppointmentSaving will be called twice.

4) Repeat every other time. (2, 4, 6, 8, etc. with no end)

Here's the XAML setting up the event handler:

<i:EventTrigger
    EventName="AppointmentSaving">
    <vp:EventToCommandAction
        PassEventArgsToCommand="True"
        Command="{Binding HandleDowntimeSavingCommand, Mode=OneWay}" />
</i:EventTrigger>

Here's the event handler itself:

public ICommand HandleDowntimeSavingCommand => DelegateCommand.Create<AppointmentSavingEventArgs>(HandleDowntimeSaving);
internal void HandleDowntimeSaving(AppointmentSavingEventArgs eventArgs)
{
    var downtime = (DowntimeViewModel)eventArgs.Appointment;
    var numExceptionsRemoved = RemovePointlessExceptions(downtime);
    var numExceptionsConverted = ConvertExceptionsToIsolatedDowntimes(downtime);
    if (numExceptionsRemoved > 0 && numExceptionsConverted == 0)
    {
        eventArgs.Cancel = true;
    }
}

DelegateCommand.Create is used in literally thousands of places; it's not the source of the bug. If I set a breakpoint on the first line of the event handler, it will be hit twice, but only on every second edit.

Hi! I'm using the implementation from the RowReorder-demo to get drag-n-drop in my RadGridView. It works really good, but I have an issue with copying. When reaching OnDrop the e.Effects are ALWAYS DragDropEffects.All (even when just moving an item).

In OnGiveFeedback the e.Effects is DragDropEffects.Copy (if pressing Ctrl), but it's not in OnDrop. I also checked the OnPreviewDrop method, but it's DragDropEffects.All there also.

Do I have to add something somewhere? In OnDragInitialize the e.AllowedEffects are set to DragDropEffects.All.

I am trying to figure out if it is possible to set the AutoFitColumnWidth or control the width of a column for the PDF output of a WPF Grid?

I have the following code for setting up my export options.

I do not want ALL columns to auto size, because I have columns with single digit values in them and they look terrible squished together. I REALLY would like to set the width manually so the output looks good. 

My Grid columns are all Width="*" on the XAML side. And as you can see I am subscribing to the "ElementExportingToDocument" event and styling the grid to look the way it needs to look as far as foreground and background sizes. 

Are we limited only to the CellSelectionStyle properties when it comes to customizing the export? 

I'm just trying to do something that seemingly should be simple... trying to map individual checkboxes in a telerik:GridViewSelectColumn in a telerik:RadGridView to a corresponding Boolean property of an entity mapped for each individual row.

How do I map MyBooleanProperty in each row/entity to each individual checkbox represented in the Grid?

Hi, 

As part of application development, we are using the Telerik:RadTreeView to support UI viertualization in the tree view.

We have a requirement to make a data subscription to each tree view item after finish loading all of the items... basically would like to when virtualizaiton loaded the visible items and unloaded the invisible items...

Is there are any event or sample code to refer for above functionality?

I am new to this... and gone through RadTreeView documentation, but didnt find any suitable events for this..

Thanks

Rama. 

Dear Telerik Admin Team

I have some issues during using RadRibbonView,Kindly help me to solve them. Any feedback I do appreciate.

1. How to use Build-in theme for RadRibbonView? For example I found a theme Office2016 that really very beautiful and I would like to use it as default theme.

2.Please see attachment 'RibbonTab Cannot display normally", In this case I have add some RibbonTab into RibbonView, but only selected RabbionTab can display and other cannot see correctly, I tried to move mouse and hover on unselected RibbonTabs, I can see these RabbionTabs, this is very strange.

3. When I collapsed RabbionView, what I expected should be that only tabs header display correctly, but after collapse I cannot see anything, really very strange.Please see attachment 'Collaspe issue'.
