Hi Team,

I would like to set few styles, namely TextDecorations like StrikeThrough, Underline and other styles like Horizontal Alignment, Boldness and Font Style programmatically by creating a FrameworkElementFactory of type Textblock and then assigning the same to a DataTemplate of type GridViewRow, which is then assigned to the ContentTemplateProperty of the GridViewRow; but to no avail.

Could you please guide me on the same.

Please let me know if any details/clarifications are required.

Thanks,

Swapnil Ramteke

Hello

I used the following code to export to image

        Dim filename As String = "C:\Export\ExportedChart.png"

        Using fileStream As Stream = File.Open(filename, FileMode.OpenOrCreate)
            Telerik.Windows.Media.Imaging.ExportExtensions.ExportToImage(Me.chart, fileStream, New PngBitmapEncoder())
        End Using

But the exported image misses the X and Y coordinate values. How can I export the image exactly as seen in the UI

I would like to export to PDF as well.

How can I display the X and Y values in the tool tip for radCartesianchart bar series

In radChart, there is a option as below:

<telerik:BarSeriesDefinition ItemToolTipFormat="the X value is #X, the Y value is #Y"ShowItemToolTips="True" />
    </telerik:SeriesMapping.SeriesDefinition>

Hi,

I would like to use middle mouse to move viewport ?

Can you help me please ?

Thanks,

Hi,

we are using telerik-wpf controls for years now and are very happy, thanks so far. Now we are looking for a possibility to change
XAML Pages during runtime with an GUI Interfacec. We want to load the XAML page with its elements and display them. Some of
the elements should be protected. With drag & drop the user should be able to place a new textbox in the page an link this textbox
with a database-field.
After saving the user should only reopen the changed mask in the application and it should show the new field!

Is this possible with telerik controls in one way?

Thanks
Best Regards

Hi,

the last days, our customers suffer from following exception in our WPF/MVVM/PRISM/C# application. It is in German, but I give a translation for the important parts:

Source: PresentationFramework

HelpLink: null

Message: Beim Auswerten der Style-Eigenschaft für Element "Telerik.Windows.Controls.RadRibbonTab Header: Items.Count:0" wurde ein zyklischer Verweis gefunden. Translation: Cyclic reference found while evaluating the style property for element "Telerik.Windows.Controls.RadRibbonTab Header: Items.Count:0"

The exception appears when I open the application, don't use it for at least one minute and then open a new dialog of the application. The dialog contains a RadRibbon usercontrol. Sometimes the exception occurs when I don't wait a minute, but it appears more reliable if I do.

It does not appear when I debug the application. However, If I use the release mode in Visual Studio 2015 and start the application without debugging, I can reproduce the exception.

Since I cannot debug the application for this issue, I only hope for a flash of inspiration on how I could further approach this issue. If you need further information, please tell me.

Thank you!

Hi all,

we are trying out Telerik drag and drop. We want to drag between 2x itemslist and a DockPanel. To be able to use Telerik drag visualizer we converted both the itemslist to a ListBox (not 100% what we wanted though, because listbox looks different).
This way we get a 'shadow' of the item we drag during the dragging. And an arrow indicating we can move the item (or red circle if denied).

The problem now is we want to deny certain drops in the dockpanel based on the data in our viewmodel. How can we accomplish this?
I can catch the events of the dockpanel like OnElementDragEnter, but I cannot set the e.Effects property to none. Also I don't have options class in my e.data object (like in your treeview example).

Also tried to set the dockpanel.allowdrop to false during drag. That works, but then the next time the drag over event wont fire again :(.

(the way we did this before Telerik components was just set the DragDropEffects.Effects to DragDropEffects.None)

Thanks in advance

Hi, 

I'm using the RadTimeLine control. I want to draw a connection between two timeline item, just like the following figure shows. Is there any way to do that?

I know it's easy to do with RadGanttView. But the RadTimeLine  is more flexible than RadGanttView. For some reason this must be implemented in the RadTimeLine.

Hope for reply!

Best regards,

Jie
