Hi,

I have a problem with the "Export to image"  feature of the RadDiagram.
In particular when I export an image with lots of RadDiagramShape and RadDiagramConnections the image has a  correct dimension, but the shapes and the connections are blurred. 

The following is the piece of code which I use to  serialize the image and I' ve attached  an example of exported image.

using (var rawImageStream = new MemoryStream())            {
                diagram.ExportToImage(rawImageStream, margin: ExportMargin, backgroundBrush: new SolidColorBrush(Colors.White));
                rawImageStream.Seek(0, SeekOrigin.Begin);

                using (var trimmedBitmap = new Bitmap(rawImageStream).Trim(0xffffff)) {
                    trimmedBitmap.Save(outputStream, ImageFormat.Png);
                }
  }

Is there a way to improve it and render the exported image clearer?
Thanks

Ciro

Is there an example available that demonstrates the usage of the ModalEditor class for the property grid?    

I'd like to specify my own editor template for a particular field using the DataTemplateSelector.   The editor would display a modal window.

Thanks.

Im getting the following exception when i try to create a QRCode and render it as an image in c#.


Im using 2014.2.729.40. Attached is a new Telerik Wpf app project that shows the same behaviour as my program.

TelerikWpfApp1.zip

Am I missing some vital property or is this a known issue?

Thanks,

is it possible to show Two different SeriesItemLabel in RangeBarSeriesDefinition for High/Low value?

I have a muliple hierarchy Gridview with a context menu and I would like to pass the current row from the grid when clicking a particular item from grid, however when I do check check for the method handler in the VM, the parameter is always null.
What I would like to do is get access to the Row datacontext in the grid when a user clicks on the menu.

Any ideas ?  Here's my VM code:

private async void GetEnquiry(object enquiry) { }

Hello,

So I have a GridView in which I can add new rows and within the columns I can select some combo boxes and a date Picker.

This is how it looks before anything is changed


When I change one row at a time and click save it works, the problem is when I multiple rows and combo boxes and I don't click away From the Final Combo Box. It doesn't register the Final Combo Box changed. Pictures below will illustrate what's happening.


Notice the second "Maintained" is currently showing within a combobox, that means it won't register the change until it's clicked away.


You can see here that after the save button is clicked, it reverts back to the value it was before because it wasn't "Registered"



But if I click away such that the ComboBox stops appearing and click save, it works. Image Below.


May I ask How to fix this? 

Hi,

actually with the control I have a FilteringBehavior which display only the items in the dropdown that contain what I typed. When I have a lot of items in the dropdown the control take some time to display the dropdown even of the MaxDropDownHeight property is set to 250 and I would like to know if it's possible to increase the speed of the popup display?!?

Thank's
Alain

Hello there,

I do believe this question has an answer on this forum, however I could find it for now. Could you please point me in a right direction.

We have requirement to organise grid columns in 2 rows, please see attached image. How this can be achieved with GridView for wpf ?


Thanks in advance.

The email was rejected somehow, so I post the reply here.

And you http://feedback.telerik.com/ can NOT upload any file!

Alex,
I have still evaluated the UI for WPF.

I found the component is not so compatible with Chinese which it is addressed as following snapshot:

1) Define some Chinese menu in XAML(Use one of demo example you provided)
(snapshot 1)

2) compile error: Invalid character specified, line 31, position 54, .'' XML invalid.
(snapshot 2)

3) If the menu is changed to ASCII, it compile successful.

Platform:

• VS2013 Chinese version
• Win 7 Chinese version

I hope the problem will be solved A.S.A.P before I make a decision.

Regards,

Hi Sun,

To follow up on my previous email, I was curious how your evaluation is going?

I also wanted to check in to see which resources (support tickets, forums, blogs, Telerik TV) you found the most useful during your evaluation, and if you encountered anything that would prevent you from recommending Telerik?

Your feedback is greatly appreciated.

After upgrading to WPF Q2 2014, the StrokeDashArray property stopped working for me.  I confirmed with the same project linking to Q1 2014 that the property is working.

Here is the XAML that reproduces the issue.  Any ideas?  Note that the Stroke and StrokeThickness properties are being updated correctly to Red and thickness 2.  It's just the StrokeDashArray that stopped working.

<chartView:ScatterLineSeries ItemsSource="{Binding LineData}" XValueBinding="XValue" YValueBinding="YValue">
     <chartView:ScatterLineSeries.StrokeShapeStyle>
          <Style TargetType="Path">
               <Setter Property="Stroke" Value="Red"/>
               <Setter Property="StrokeDashArray" Value="10 5"/>
               <Setter Property="StrokeThickness" Value="2"/>
          </Style>
     </chartView:ScatterLineSeries.StrokeShapeStyle>
</chartView:ScatterLineSeries>
