Hi
How to Use ColorAnimation to change the background of RadButton when IsMouseOver is True
, this is my code

<Style TargetType="telerik:RadButton">
            <Style.Triggers>
                <Trigger Property="IsMouseOver" Value="True">
                    <Trigger.EnterActions>
                        <BeginStoryboard>
                            <Storyboard >
                                <ColorAnimation From="Green" To="Yellow" Storyboard.TargetProperty="(Button.Background).(SolidColorBrush.Color)"  Duration="00:00:03" RepeatBehavior="Forever"/>
                            </Storyboard>
                        </BeginStoryboard>
                    </Trigger.EnterActions>
                </Trigger>
            </Style.Triggers>
        </Style>


But is not working.

Thanks,

Hello,

I have a problem with the TimelineViewDefinition. I have my ScheduleView with a timeline view defined. In this view I need to show only one day, and to achieve this goal, I define the attribute VisibleDays and I set it to 1. This shows perfectly fine as expected, I get one day in the timeline view. But when in a button I call the RadScheduleViewCommands.DecreaseVisibleDateLarge or RadScheduleViewCommands.IncreaseVisibleDateLarge, the Schedule advances one week instead of one day as it should. How can I solve this?

Thank you!

Hi,

<RadDiagram ...>
<primitives:GraphPaper />
</RadDiagram ...>

That tag causes an exception to be thrown:

A first chance exception of type 'System.InvalidOperationException' occurred in Telerik.Windows.Controls.Diagrams.dll

Additional information: Cannot modify the Items collection when the GraphSource is set.

What's up?

I know that since Q2 RadPdfViewer has a new property called Mode for choosing between pan and text selection. However the example in http://www.telerik.com/help/wpf/radpdfviewer-wiring-ui.html seems to use an old way. (It also doesn't have the example for text selection or find in the xaml even though the find is in the provided code behind).

It is probably just because I am new to WPF but I can't figure out what to do in the xaml. Could someone give me an updated example? Thanks.

Regardless of how I attempt to set the visibility for it, I cannot get the FilteringDropDown control within the GridViewHeaderCell for a column bound to a custom type to appear in my RadGridView. Sample code below:

 

Both with and without the HeaderCellStyle I do not get the FilteringDropDown. If I run the application with WPF Inspector or Snoop and change the FilteringUIVisibility from collapsed (which it always is) to visible (which the default is and what I set it to manually) then the FilteringDropDown appears and I can use my custom filter. I am assuming some code in the control is overriding my styling based on the non-standard object type (which is why I have custom sorting on the column as well) but I cannot figure out how to avoid it or restore the FilteringDropDown.

Hello,

Recently we updated the Telerik assemblies in our product to 2012.3.1017.40 and we've encountered an issue. When the user drags a column header to the group panel they encounter a NullReferenceException. We're hosting the control in a Windows Forms ElementHost control.

Any ideas on a workaround would be very helpful.

Hi

I'm using the latest released 1129 build.  Create a new document.

Add text such as

"Heading 1

Heading 2"

Highlight all, set to Heading 1 style.

Generate ToC.  This will not work.  The code throws an exception during InsertTableOfContentsCommand.PrepareExecuteCore(). 

This seems to be because empty paragraphs are skipped and no bookmark added to "paragraphToBookmark" dictionary, but the later foreach loop that iterates the paragraphs and gets bookmark names from this dictionary doesn't skip any paragraphs - so the empty ones will throw an exception, as they aren't in the dictionary.

Hi

I need to select a carousel item by souble clicking it.

Once I have double clicked I need to know whcih Item I have clicked.

Do you have any examples of this ?

Kind Regards

David

For developers using the Windows 8 theme and the TabControl, be aware that if you set the BackgroundVisibility to "Hidden", the background tabs will "disappear" visually. I'm not sure I'd consider it a bug because the system is just doing what you tell it to do, but it's something that we discovered and I thought I would pass along.

I've attached screenshots for reference.
