hi 
it's my very first time using wpf , and i don't know how to create a chart and link it to my database.

any idea how to start ?

When using a RadBusyIndicator on a RadBackStageItem I receive the following error.

Dispatcher Unhandled Exception.
OnCurrentTimeInvalidated
Cannot animate the 'Opacity' property on a 'System.Windows.Controls.ContentPresenter' using a 'System.Windows.Media.Animation.ObjectAnimationUsingKeyFrames'. For details see the inner exception.Line: 0Column: 0

This happens on a dispatcher thread after the background thread has finished and I set the IsBusy to false.

How to add a blank space to the right side of the candlestick chart? 

The data received in real time!

Axis X = Date Time Categorical Axis!

I have a RadGridView (SelectionMode.Extended) with ItemsSource of type VirtualQueryableCollectionView. Source is a database wich is connected via EntityFramework.
When I select the first row in the GridView and go down to the bottom and select the last row (or any other), all items in between are fetched from the databse, although I didn't pressed SHIFT. This needs very much time I have many data.
Is there any reason, why the table thinks it has to load all rows between the first an the second selection? Is there any way, to change this behaviour?
I think, this should only happen, if I SHIFT+Click on a row.

I am working on a project that is using the RadScheduleView to populate a time off calendar for employees.  Currently when the view is rendered the appointments are listed in order of their appointment time.  I want them to be ordered based on when the appointments were submitted by the user.    This way we can see who submitted  the request first.  See attached file for a sample output of what the problem is.  In the sample, Tom created his appointment on 3/17 and Paul created his request a few weeks prior on 2/23.  I want Paul's request to be listed first and then Tom's.  It looks like the tool is sorting them based on the actual appointment  times because Tom's appoint is 12am where as Paul's appt is 10am so naturally Tom would be first.  How do I change this behavior to reflect acustom sort method.  

I am using a sorted list (sorted on date created) to populate the Appointment collection that is used for the DataContext of the RadScheduleView.

Thank you for your help.

Hi there.

How can I bind "custom control" width (that is in RowDetails of RadGridView) to an RadGridView column actualWidth?

Is that possible?

RadGridView

    |__ Column.ActualWidth

    |__ Row

          |__ RowDetails

                |__ CustomControl.Width(ActualWidth)

Thanks!!

I started getting this error after using implicit styles. I am using version 2016.1.217.45

This is my XAML for mumeric input 

<telerik:RadMaskedNumericInput Mask="########" MaskedInput:MaskedInputExtensions.Maximum="99999999" 
                                                               TextMode="PlainText" MaskedInput:MaskedInputExtensions.Minimum="1"
                                                               Width="100" IsClearButtonVisible="False" Value="{Binding Retention}"/>

If i go into the Telerik.Windows.Controls.Input.xaml and update this line then the error goes away but then the input control is not displayed at all

    - <Style TargetType="controls:RadMaskedNumericInput" BasedOn="{StaticResource RadMaskedInputBaseStyle}" x:Key="RadMaskedNumericInputStyle">
    + <Style TargetType="controls:RadMaskedNumericInput" x:Key="RadMaskedNumericInputStyle">

Hello,

I was going over the documentation page for a combo box column in a RadGridView.  The "one click" solution shows adding styles to the Column definition in XAML to set "OpenDropDownOnFocus" to true.

Is there a way this can be accomplished in code?  I am using the NoXaml binaries.  I tried the following:

But when the grid renders now, the dispaly works, but the editor for the combobox columns no longer have content. 

Since I'm using the NoXaml binaries, do I need to explicitly define the EditorTemplate as well because the EditorStyle overrides the implicit template?

I am not sure whether this should be classed as a bug or not.

When using the VisualStudio2013 Dark Theme and closing a RadWindow it "Shrinks" and fades away. However the window is still active whilst it is shrinking.

In my use case I have a RadWindow as a popup with a RadListBox containing several items. On the RadListBox's SelectionChanged Event some work is carried out and I call Close() on the RadWindow. This happens very quickly and if a user double clicks a RadListBoxItem rather than single clicking the RadWindow it is already closing and the RadListBoxItem below the selected item moves under the curser as the RadWindow "Shrinks". This item then fires the same event.

As a work around I am going to set IsEnabled=false on all my RadWindows before calling Close() as this fixes the issue.

I just wondered whether this could effect other peoples projects in different ways, and whether the IsEnabled=false should be set somewhere else within the Telerik code as an automated process.

Regards,

Shaun
