How can I change the foreground color of the TimeSpanPickerComponent?

I've tried customizing my own RadTimeSpanPicker but unable to go pass the ItemsControl in the XAML (which contains a list of RadTimeSpanPickerComponents, e.g. hour/min/sec/etc picker, but not exposed via copied template. 

-----------------------------------------

                        <telerik:RadDropDownButton x:Name="PART_DropDownButton"

. . .
                            >
                            <telerik:RadDropDownButton.DropDownContent>
                                 . . .
                                    <ItemsControl
                                        ItemContainerStyle="{TemplateBinding TimeSpanComponentStyle}"
                                        Foreground="Red"
                                        Padding="3,0" Focusable="False" 
                                        >
                                        <ItemsControl.ItemsPanel>
                                            <ItemsPanelTemplate>
                                                <DockPanel Background="Transparent" IsItemsHost="True"/>
                                            </ItemsPanelTemplate>
                                        </ItemsControl.ItemsPanel>
                                    </ItemsControl>
                                   

---------------------------------------

I've also tried to set the Foreground via TimeSpanComponentStyle

TimeSpanComponentStyle="{DynamicResource TimeSpanComponentStyle1}"

I'd appreciate some assistance. Thanks.

I used telerik WPF Radspreadsheet. 

I have a question that why you didn't make some excel formulas like SUBTOTAL, SUMIFS. (but in KENDO UI, they are already built in. )

Can I use these formulas another way in Radspreadsheet or Are you have any plans to built in those formulas in WPF Radspreadsheet? 

I am attempting to insert rows between existing rows within a worksheet. Each newly inserted row should have the cells within merged and have a text value.

I am basically calling the following in a loop on a very small spreadsheet (only 12 rows and 4 columns) and it is very slow. The spreadsheet originates from a call to grid.ExportToWorkbook().

worksheet.Rows.Insert(rowIndex, 1);

worksheet.Cells[rowIndex, 0].SetValueAsText("haha");

worksheet.Cells[new CellIndex(rowIndex, 0), new CellIndex(rowIndex, 3)].Merge();

Two issues:

Issue 1: This is very slow. Each call to insert takes a long time to execute. The entire operation takes several seconds despite only inserting 12 rows. I have suspended layout, put everything in a single undo group. The control isn't even visible at this point.

Issue 2: The cells do not seem to be merging correctly. Some of the values of non inserted rows are removed. If I comment out the call to merge, all values appear to be correct

Thanks in advance.

Hi,

I am trying to set the orientation of the minimized items in the bottom panel, so instead of being horizontally oriented I want them to be vertically oriented.

(see attached PNG file)

I though that the best approach would be to edit a copy of the TileViewPanel template/style and change it but I am unable to create a copy of it neither using Blend nor Visual Studio. 

So, is there any easy way to set the orientation of the minimized panel? If not, could you please provide me with a copy of the TileViewPanel template?

Thanks in advance.

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.
