MVVM example of using the SyntaxEditor

Hope somebody can help out here.

We have recently started using the RadSyntaxEditor in an application that uses the Prism framework. There have been some posts about the SyntaxEditor not showing in the UI unless you put it in a ContentControl. We did this and bound the Content to the SyntaxEditor instance in the VM.

This worked fine and we can add a custom tagger but none of the event subscriptions to the Document.TextContentChanged event seem to work.

If we then template the SyntaxEditor in the XAML and bind to an instance of the TextDocument like this, how do you set up a custom tagger?

<ControlTemplate x:Key="SyntaxEditorControlTemplate" TargetType="{x:Type ContentControl}">
            <telerik:RadSyntaxEditor AutoScrollToCaretOnTextChange="True"
                                      CaretDisplayMode="Block"
                                      Document="{Binding SyntaxTextDocument}">

            </telerik:RadSyntaxEditor>
</ControlTemplate>

Can anybody point us to an example of using the SyntaxEditor with MVVM please.

Thanks

RadBusy indicator not displayed in UI where RadGrid loads huge records

Hi,

I am having a WPF window with few grids containing rows varying from 2-100.  When I click on a link from a previous window, this window has to be loaded. I have used RadBusyIndicator for the entire content. And the grid population  LoadData() is being done in Tasks which is called on Window Loading. So presently my UI is displayed with all the grid without any contents and maybe after 4-5 seconds, the contents are loaded. 

I want to display the RadbusyIndicator when no contents are present and once the contents appear, it should disappear. Please find the below code I have implemented.  But in this case, RadBusyIndicator is not displayed. Kindly help.

An alternative that works presently is to put DisplayAfter = 0, here the indicator appears though it doesn't spin and later vanish when data loads.

public void LoadData( string filePath)

        {
            this.IsBusy = true;

            Task.Factory.StartNew(() => {
                OnPopulateDataDoWork(filePath);
            }).ContinueWith(t =>
            {
                this.IsBusy = false;
            }, TaskScheduler.FromCurrentSynchronizationContext());


Thanks,

Divya

RadBusyIndicator Changing theme style and not showing busy state
I'm using the implicit Fluent theme.

If you look at my ResourceTemplate.xaml, there is a Fluent theme and a Transparent theme.
Telerik.Windows.Controls only applies the transparent theme.

Is there a way to change only BusyIndicator to Transparent theme?
I want the main window to be a fluent theme.
(I know that Style.Manager shouldn't be for implicit styles.)

If you click the button, BusyIndicator opens a new window and works. But there is a problem.
BusyContent is incremented by 1 only internally.
However BusyIndicator is not displayed, only blank.
What's wrong?

Please check my source for details.

Thank you.

R2 2021 SP1 download fails to complete and VS becomes unresponsive

In VS 2019 I got prompted to update to a new version R2 2021 SP1.  I accepted and got the download window, in the download window I clicked on "Release Notes" and my Chrome browser opened with page of notes.

I return to VS and the download shows 100% complete but both the "Cancel" and "Minimize" buttons are grayed out.  Waited about 10 minutes and still the same, so I had to "End Task" VS 2019.

RadCartesianChart mixed Series filters ItemsSource wrong

Hello,

i have an issue using RadCartesianChart with mixed Series types. All series have the same ItemsSource. I know if there are too much Datapoints the chart filters some points. The problem is that not on all series the same datapoints are filtered.

In the first picture you can see that there is no Datapoint for the StepLineSeries at 16:34:29, the next closest point is at 16:34:16. It is filtered out because there are too much datapoints for this range. This would be ok if it is also filtered out at the RangeSeries.

In the second picture we are zoomed in and we see that the point is no more filtered.

In the third picture i used for all 3 series the same series type (unzoomed). Now all serieses are filtered correct the same Datapoints.

How can i change this behavior of the Chart that all series types do the filtering the same way? In my opinion this behavior is wrong. I would expect the bevavior of Picture three also for different series types.

<telerik:RadCartesianChart.Series>
          <telerik:StepLineSeries DisplayName="Value" Stroke="DodgerBlue" StrokeThickness="1" ItemsSource="{Binding Data}" CategoryBinding="Timestmp" ValueBinding="Value"></telerik:StepLineSeries>
          <telerik:RangeSeries DisplayName="MinValue" Stroke="#88FF0000" StrokeThickness="1" Fill="#44FF0000" ItemsSource="{Binding Data}" CategoryBinding="Timestmp" LowBinding="LowBinding" HighBinding="MinValue"></telerik:RangeSeries>
          <telerik:RangeSeries DisplayName="MaxValue" Stroke="#88FF0000" StrokeThickness="1" Fill="#44FF0000" ItemsSource="{Binding Data}" CategoryBinding="Timestmp" LowBinding="MaxValue" HighBinding="HighBinding"></telerik:RangeSeries>
</telerik:RadCartesianChart.Series>

RadComboBox - how do i prevent the ComboBox from changing SelectedItem until i click on one ?

I'm using the ComboBox with the autocompleter / text enabled search. 

I want to prevent the ComboBox from changing Selected Item until I actually click on an item or press enter... 

Currently the RadComboBox changes the SelectedItem when browsing the elements (arrow up or down) which is not desired.

<telerik:RadComboBox Width="150"
                                 Height="25"
                                 Margin="115,10,0,0"
                                 HorizontalAlignment="Left"
                                 VerticalAlignment="Top"
                                 DisplayMemberPath="FabrikatNavn"
                                 IsEditable="True"
                                 IsEnabled="{Binding CanChangeVariant}"
                                 ItemsSource="{Binding Source={StaticResource SortedBrands}}"
                                 OpenDropDownOnFocus="True"
                                 SelectedItem="{Binding ElementName=root, Path=BrandModel.SelectedCarBrand}"
                                 StaysOpenOnEdit="True" />

RadGridView: Databind to or manipulate the FullTextSearch

How the heck do i databind or manipulate the FullTextSearch Text ??

I've tried doing perfectly normal / sane / obvious databinding in XAML like this: 

<telerik:RadGridView TextSearch.Text="{Binding MyTextProperty}">

but that doesn't work - maybe because its not the correct property -- can't find it in documentation or as property on the radGridView instance..

I've also tried figuring out the binding example from this Forum called https://www.telerik.com/forums/bind-full-text-search-to-custom-textbox but failed to do so.. 

Why is the FullTextSearch String property not exposed in a normal behavior like with a DependencyProperty ???????

Why is this so hard ?

Why are the SearchPanel hardcoded instead of exposing a customizable panel ??

eg: If i want to add a button that clears all Search Filters , i need to make ugly hacks :(

White Line in Stacked Chart

We are using RadChartView to display some complex data. The requirement is to have a stacked column with 4 stacks above 0, 4 columns stacked below 0 and those need to have categories.

In XAML Code this looks like this:


<telerik:RadCartesianChart Tag="Text">
                    <telerik:RadCartesianChart.Grid> 
                        <telerik:CartesianChartGrid MajorLinesVisibility="Y" /> 
                    </telerik:RadCartesianChart.Grid> 
                    <telerik:RadCartesianChart.HorizontalAxis> 
                        <telerik:CategoricalAxis FontSize="11" LabelRotationAngle="45" LabelFitMode="Rotate" SmartLabelsMode="SmartStep"  /> 
                    </telerik:RadCartesianChart.HorizontalAxis> 
                    <telerik:RadCartesianChart.VerticalAxis> 
                        <telerik:LinearAxis LabelFormat="N2" SmartLabelsMode="SmartStep" /> 
                    </telerik:RadCartesianChart.VerticalAxis>
                    <telerik:RadCartesianChart.Series>
                        <telerik:BarSeries x:Name="CrNoScoreColumn"

I attach the chart as an image to this post. You can see there is a white line with around 1 pixel on every column. i can further say the border Y position and height make this white line.

The second clue i can give is that once i remove the negative series or make their value 0, the line is gone.

for example:


<DataTemplate x:Key="ElementCrDbColumnChart"
                          DataType="{x:Type charts:ChartDataContext}">

                </telerik:RadCartesianChart>
            </DataTemplate>

result in a chart with no white line. the same data. everything the same except for the barseries.

As a second side question: why is the line series not drawn? Any idea - it worked and some day without changes it disappeared and only the points are still drawn.

 

i hope we can get some solution here soon. we need this to work under any circumstances and with alle the above mentioned requirements. since we have telerik and componentone licences we will try to use their chart control for the time being but i would really want to use telerik if possible.

Bug: RadComboBox bugs the Visual Studio 2019 UI

While editing the XAML document, I'm experiencing weird behavior in VS2019. 

All examples applies when the Design editor is active together with XAML editor.

Example 1:

Selecting XAML with mouse stops when i start selecting the telerik:RadComboBox 

Example 2:

Copy Pasting bugs out, either the selection is empty or incorrect !

Example 3:

'Forcus' in Visual Studio is sometimes overtaken by the RadComboBox which is very annoying.
