Is there a way to make either the RadMaskedNumericInput or RadMaskedTextBox accept only non negative integers?

I am a long time Telerik user, and I love the ShowColumnWhenGrouped attribute, I've wanted this functionality for a long time.  It works great when the user drags a column to the group bar, but when set in XAML with a column grouping defined in XAML, it is ignored.  Is this a bug, and is there a workaround?  Thanks.

Hi,

i can't find how to load a second combobox on demand depending  what is selected in the first combobox? For Example, i select "Audi" in
the first combobox and the second should load all Audis "A1, A2, A3, A4, A5,..." out of a csv-File!

Thanks
Best Regards

I'm trying to make a custom appointment following this tutorial. I clone the style using Right Click -> Edit Template -> Edit a Copy. The resulting code has several  ambiguous reference error. I read that the solution is to use the fully qualified namespace but I don't know which option is correct.

One of the errors is in the line 

Hello,

i am using a Gridview that is having a RadObservableCollection<T> (where T is DependencyObject, INotifyPropertyChanged) as ItemsSource. The same collection is also used in a Chartview as Datasource for a Lineseries.
Any changes in the Chart (Drag&Drop) are reflected in the Gridview and the other direction works too.

My problem is the way the editing is passed on:
I have a Double Column which is editable and reflect the values that are shown in the Chart too. But the editing changes are passed on the the chart on every keypress during the editing which is very irritating.

So lets say someone wants to enter 749 as new value the behavior is now like this:

• press key 7 -> datapoint in chart jumps to Y-Value 7
• press key 4 -> datapoint in chart jumps to Y-Value 74
• press key 9 -> datapoint in chart jumps to Y-Value 749

what i want is this:

• press key 7 -> nothing
• press key 4 -> nothing
• press key 9 -> nothing
• press return -> datapoint in chart jumps to Y-Value 749

I guess I need to block some notification sending in the BeginningEdit event and pass out the final new value only in the CellEditEnded event. But i havent been able to work out how.

Thanks in advance!

I've run into a problem where if the DataContext is set too late in the initialization/rendering process, bindings on the IsVisible property of columns are never established. Below is an example showing the problem.

If you establish the DataContext in the constructor, it works as expected; the Number column is not shown, and you can toggle its display using the checkbox.

However, if you comment out that line, run the app, and use the button to establish the DataContext after the grid has rendered, the Number column is shown even though ShowNumber is false, and the binding does not respond to changes in ShowNumber (again using the checkbox).

I found a work-around by re-establishing the binding after setting the DataContext, but this is ugly and much less maintainable.

Is there a way I can force it to update the column bindings when the DataContext is set, rather than re-creating the binding for every column on which I need to control visibility?

Thanks,
Louis

XAML:

Code-behind:

I have an application where I am using buttons across the top that are styled a certain way.  I can seem to figure out how to get that same style to apply to the top level menu.  So I need to know how to apply a chrome button style to a top level menu?  Submenu popup should remain with the default style. Just wanted to change
the style of the main menu so that when we hover over it looks like chrome button.

Here is the styling we are doing on the Button.  Right now, I can't seem to achieve the mouseover effect this has for Top Level menu

<Style TargetType="{x:Type telerik:RadButton}">

                                                                    <Setter Property="Padding" Value="4" />
                                                                    <Setter Property="Margin" Value="1,1,0,1" />
                                                                    <Setter Property="IsTabStop" Value="False" />
                                                                    <Setter Property="Template">
                                                                        <Setter.Value>

                                                                    </Setter>
                                                                </Style>

Hi.

I looked for 'RadProgress Demo - First Look'

In the demo, when 'IsIndeterminate' button is checked appeared.

I want this shape progressbar.

How make this?

Hi all

I have a RadScheduleView grouped by resources in a horizontal view. My problem now is that if the view does not contain many rows, every row is stretched so that the rows take all space (see screenshot). This doesn't seem to be because of any of my templates (which don't resize).

In order to simplify diagnosis, please check the second screenshot. I overwrote the height of all elements in the style, including the groupheader (green background). Basically, that GroupHeader doesn't have a parent anymore, it's just part of it's parent (AppointmentsPanel). I assume that parent stretches content, which I something I'd rather not have as it screws the layout.

What I basically want is a automatic height, rather than the control stretching all rows to take up all vertical space. Any idea how I can set this?

Thanks
Philipp

Hi all

I have two different RadScheduleViews, both grouped by a shared collection of resources. A resource represents an employee.

Now, from my group header (for which the data context is the employee resource), I would like to navigate to the same employee on the other RadScheduleView. As far as I can tell, I need an appointment to do so with the RadScheduleView.ScrollIntoView, which I can determine from my resource. However, that means I can't navigate if there are now appointments for the employee yet. How can I accomplish this?

Thanks,
Philipp
