Hi Guys,

is it somehow possible to override the "IsChecked" style of a RadToggleButton within the RadToolBar?
I would like to have a "working"-spinner animation when a button is pressed.

Thank you very much.

I am trying to build a TreeView/Property Grid pair for my application.  In my application I have implemented the Hierarchical Data Template as described in the online documentation (https://docs.telerik.com/devtools/wpf/controls/radtreeview/populating-with-data/hierarchical-data-templates).  This populates the TreeView control as expected.

In binding the property grid to the SelectedItem of the TreeView, I found that I can only see the properties for the first TreeNode that is clicked.  In troubleshooting I tried updating the PropertyGrid through code, but I found that the SelectionChanged event only fires for the first node that is clicked on.  Any subsequent selection changes do not result in the SelectionChanged being fired.

How can I build this typical functionality into a Hierarchical Data Template based TreeView control?

Hello, 

When I add a TextBoxField to an interactive form, and set it to IsReadOnly=true, I can still modify the value and it saves with the document.

Is there a fix to that?

Hi Telerik,

I have a ribbon that I need to behave a little differently.

1.  I need it to always pop up the way that the ribbon does in "Minimized Mode"

2.  I need it to not auto-close when the window focus is lost or when something is clicked outside of the ribbon.

What's a good way for me to make this happen?

HI,

I have seen that issue was raised already last year.

https://www.telerik.com/forums/richtextbox-doesn't-paste-google-documents-bullet-list#XzDTvIATk0ijGU2xwH5BPQ

I would like to know if anything was done to fix it?

I have installed Office 15.0.5041.1001 and I cannot copy paste any bullet list.

Copying and pasting work in case of users which have version 15.0.5031 (I don't know if it is coincidence or not).

Thanks in advance for quick answer

Hi, 

Currently i'm trying to implement virtualization layer with IMapVirtualizationSource to improve the performance of plotting in map.

it is working well.

my question is, is it possible to use data template for this layer? because when i tried to implement data template, it's not showing anything. if i create the data using ellipse object like in documentation, it shows all the data fine.

I follow the guide from this: https://docs.telerik.com/devtools/wpf/controls/radmap/features/virtualization-layer

My other question is, is it possible to change the layer opacity? because no matter what value i assign, it is still not changing the opacity

this is how i change the opacity:
    var vi = new VirtualizationLayer();
            vi.ZoomLevelGridList.Add(new ZoomLevelGrid(6));
            vi.Opacity = 0.5;

If i assign the item into vi.ItemSource, the opacity works, but it is not using the virtualization.

Thanks.

How to change series color for a series as per some range values for different data  points of the same series ? For  example I want to show blue color for data points  between range -10-0 degree celcius , yellow color for data points  between range 0-25 degree celcius & red color for data points for the same series between range 25- 100 degree celcius. I want to do it for BarChart , Polar chart & Radar chart of Telerik WPF controls.

https://docs.telerik.com/devtools/winforms/chartview/customization/custom-rendering 

I have demonstrated example described on above link . I just want to same thing with WPF bar chart , polar chart . Please suggest easiest way .

I'm trying to using MVVM binding for the pdfviewer but the document always turns out blank.  I'm querying a DB field that contains the bytes of the PDF file and I'm trying to get it to display in the viewer (I've confirmed that the file is not malformed and it displays fine if I save it as a PDF to my desktop).

Here are my MVVM properties:

private RadFixedDocument _currentDocument;
public RadFixedDocument CurrentDocument
{
    get => _currentDocument; set => this.RaiseAndSetIfChanged(ref _currentDocument, value);
}

Here is the method I'm using to populate the CurrentDocument property:

var sqlStr = @"select top 1 * from FileManager order by ID desc;";
var file = await con.QuerySingleAsync<FMFile>(sqlStr);
var fileBytes = file.FileContent.ToArray();  // this is type byte[] - I confirmed that it has the correct contents
var ms = new MemoryStream(fileBytes); // ms gets filled properly
FormatProviderSettings settings = new FormatProviderSettings(ReadingMode.AllAtOnce);
PdfFormatProvider provider = new PdfFormatProvider(ms, settings);
CurrentDocument = provider.Import();

And here is how my XAML looks:

<telerik:RadPdfViewerToolBar RadPdfViewer="{Binding ElementName=pdfViewer, Mode=OneTime}" />
<telerik:RadPdfViewer x:Name="pdfViewer"
                              Grid.Row="1"
                              DocumentSource="{Binding CurrentDocument, Mode=TwoWay}" />

However, nothing get's displayed in the viewer.  I confirmed that my VM is hooked up correctly as other property display just fine.  Any advice would be appreciated.

I have an object with some properties, such as:

I would like to have possibility to dynamically change series which I plot at the chart.

Eg. to have ComboBox with string items: "Temperature" and "Humidity" with binding SelectedItems={Binding SelectedSeriesName}
In ViewModel property "SelectedSeriesName"
In chart
<telerik:StepLineSeries ItemsSource="{Binding Results}" ValueBinding="{Binding SelectedSeriesName}" CategoryBinding="Date"/>

of course that is not possible due to ValueBinding must be string.

How can I make this scenario corect?
