The first row has to be filled with Comboboxes with Options to choose , the second Row I get from a Database.

The ammount of Columns will change every time so i have to do it dynamically

What would be my best approach? i attached a screenshot thats shows what I want

Hi,

I'm having trouble getting list item ("li") element properties ignored using the HtmlFormatProvider export settings.  In the following example "h1" properties are ignored correctly, but the "li" ones still come through in the output.

settings.PropertiesToIgnore["h1"].AddRange(new List<string>()
{
    "margin-top", "margin-bottom"
});
settings.PropertiesToIgnore["li"].AddRange(new List<string>()
{
    "margin-right", "font-family", "font-size", "color"
});

I notice, looking at HtmlDocumentExporter.ExportBlockContainer, that the call to HtmlHelper.IsPropertyForbiddenForExport passes in "value" as the propertykey rather than a css property name (see below).  Is that correct or am I doing something wrong here?

this.writer.StartTag("li");
if (!HtmlHelper.IsPropertyForbiddenForExport(this.Settings, "li", "value"))
{
    HtmlWriter htmlWriter = this.writer;
    int listItemIndex = this.GetDocumentListForParagraph(paragraph).GetListItemIndex(paragraph);
    htmlWriter.AddAttribute("value", listItemIndex.ToString());

}

Many thanks

I've long been showing a ScatterLineSeries on my RadCartesianChart that uses a MultiBinding in the ItemsSource.  I needed this multibinding because the underlying points are expressed in millimeters but the display can be in any units the user chooses and which the user can change. So I have to convert on the fly.  So I wrote a converter that takes 5 elements 

1. An array of points to be converted
2. The source X unit
3. The source Y unit
4. The destination X unit
5. The destination Y unit.

It then returns an array of points converted to the appropriate units.  This works fine.  It looks like this:

However now I need to show several plots on this graph, not just one.  But the number varies.  So I need to use a ChartSeriesProvider.  So I did, with a ScatterSeriesDescriptor.  At first it seemed to work -- I got my points -- but then I realized that it iis not converting my points anymore.  It is completely ignoring my "ItemsSource" binding in favor the of the "ItemsSourcePath" property in the descriptor.   

Here's what it looks like:  First I defined a style for each ScatterLineSeries

<Style x:Key="SeriesStyle" TargetType="{x:Type tk:ScatterLineSeries}">

Then, inside chart, I defined the seriesprovider and descriptor and used that style in it:

Again, this mostly works.  My points get plotted.  My "SeriesStyle" even gets applied to the ScatterLineSeries (e.g. If I set the stroke to "Yellow" in that style, I see a yellow plotline).  But the final element of that style -- ItemsSource -- does NOT get applied.  I've tried putting a breakpoint inside the converter.  It never gets invoked.  So my points all remain in millimeters.

I took a closer look at ScatterSeriesDescriptor, hoping I could find a property that would let me achieve my MultiBinding.  I see XValuePath, YValuePath and ItemsSourcePath, and a few other properties ("TypeConverter", "TypePath", etc) but I cannot see any way to apply a MultiBinding to the series of points.

Can you suggest a way I can work around this?

Hi.

I set an style with to change stroke thickness of a shape but I want something like aureole or corona(not corona virus). I attached an image to see what I want.

My style that I set Is

Hi,

Firstly I removed the delete button from Schedule view Appointments and I am trying to delete the Appointments using a button added in the UserControl to do the same.

From the code behind  I invoked the RecurrenceChoiceDialog as this below.

    Telerik.Windows.Controls.RadScheduleViewCommands.DeleteAppointment.Execute(ScheduleView, ScheduleView);

1) Actually I noticed that Whenever we selected the "DELETE THE SERIES"  -> AppointmentDeleting event of the schedule view is firing (Here I set a Boolean isSeriesSelectedForDelete as true).

2) Whenever I select "DELETE OCCURENCE" there is no event firing I noticed. But I have managed it by adding like this

            Telerik.Windows.Controls.RadScheduleViewCommands.DeleteAppointment.Execute(ScheduleView, ScheduleView);
            if (!isSeriesSelectedForDelete)
            {
                var check = vm.Appointments.First().RecurrenceRule.Exceptions.Any(x => x.ExceptionDate == vm.SelectedAppointment.Start);
                if (check)
                    vm.DeleteOccurenceOrSeries(false);
            }

I could have reduced a lot of codes like this. if I get a result from the dialog which includes whether the user is clicked OK or CANCEL which one is selected Series or Occurrence . I think my scenario is clear and you can help me out. 

Thanks.

Hello I encountered a bug or odd behaviour in the RadNumericUpDown control. I use caliburn micro as a MVVM framework to bind a simple property to the Value of the control. On KeyDown I check the value and if a condition fails, I reset the value to the last valid state.

The Problem is that the Value is not updated despite the PropertyChanged event firing correctly. The value is updated after the focus is lost.

Hi,

I have implemented RadScheduleView for WPF application. However I am experiencing some delay in loading the AppointmentDialog while trying to create an appointment. The same is noticed while trying to edit an appointment. I tried  attaching a sample project, but it shows not supported..

Please suggest what could be the reason for the delay.

Thanks,

I have a RadChartView with a DateTimeContinuousAxis.  I want my first and last labels to display a particular format (such as YYYY-MM-dd HH:mm:ss), but I want all my inner labels to show a different format (such as simply HH).  I was going to do this with the LabelTemplateSelector based on the AxisLabelModel's CollectionIndex.  However, I don't see a way to tell when I'm at the last label. The documentation of CollectionIndex says

"An AxisLabelModel for example will have this property set to the index of the label within the Telerik.Charting.AxisModel.Labels collection."  However, AxisModel is an internal class, so I cannot access the Labels collection to tell how many labels are on the axis.

How do I get the number of axis labels in my LabelTemplateSelector?

I was following the above post regarding using a GridView and CompositeFilterDescriptor to filter a chart, however, I noticed that the example only applies to RadChart, and not RadChartView. When I attempted to implement it on a RadChartView item, I was met with a missing reference error because CartesianChart (in my case) does not have a reference to FilterDescriptors.

Is there any way to achieve this same effect with the current RadChartView? I would really like to avoid having to use a RadChart in my application if possible.

Thanks!
