How to Align CheckBox check status with TreeView Selection and vice versa?

I am using RadTreeView with IsTriStateMode="True" and IsOptionElementsEnabled="True" options. i am having an issue on aligning the selection of TreeViewItem and the checkbox state. i tried binding IsChecked and IsSelected properties, but did not work as expected.

I prefer doing in XAML. Any suggestions?

Change Fluent themes accent color

Hi,

Is it possible to change the AccentColor in XAML?

I want to do something like this, but in a global style.xaml:

FluentPalette.Palette.AccentColor = (Color)ColorConverter.ConvertFromString("#FF0078D7");

FluentPalette.Palette.AccentFocusedColor = (Color)ColorConverter.ConvertFromString("#FF4CB0FF");

FluentPalette.Palette.AccentMouseOverColor = (Color)ColorConverter.ConvertFromString("#FF008EFF");

FluentPalette.Palette.AccentPressedColor = (Color)ColorConverter.ConvertFromString("#FF0063B1");

Best regards,

Moritz

Dynamically changing style of MS controls alongside Radcontrols

I'm building an app where the user can switch the appearance of the UI controls a runtime.

I do this in codebehind like so:

StyleManager.ApplicationTheme = new MaterialTheme();

MaterialPalette.Palette.FontSize = 12;

MaterialPalette.Palette.MainColor = (Color)ColorConverter.ConvertFromString("#FFFC0EF1");

MaterialPalette.Palette.FontFamily = new FontFamily("Calibri");

But besides the radcontrols, there are a lot of MS controls (mostly Label), who's color, font and size i also have to switch.

And (to my surprise) there is no "RadLabel" or "RadTextBlock".

So how can I accomplish this with the regular controls? Can I make them "listen" to the StyleManager.ApplicationTheme ?

How to have a zero based x axis ?

I have the following (simplified) xaml:

<telerik:RadCartesianChart x:Name="chart">
<telerik:RadCartesianChart.HorizontalAxis >
<telerik:CategoricalAxis />
</telerik:RadCartesianChart.HorizontalAxis>

<telerik:RadCartesianChart.VerticalAxis>
<telerik:LinearAxis />
</telerik:RadCartesianChart.VerticalAxis>

<telerik:RadCartesianChart.Series>
<telerik:LineSeries Stroke="Blue" ItemsSource="<Binding to a double array>"
</telerik:LineSeries>
</telerik:RadCartesianChart.Series>
</telerik:RadCartesianChart>

By default the x axis starts from "1" (See picture). How to have the x axis starting at "0" ?

Thanks

here is the setup

1. using wpf controls version 2013.3.1316.45.

How to handle VirtualQueryableCollectionView exceptions?

I have a RadGridView that is bound to VQCV.

internal class TestContext : DbContext

{

public DbSet<City> Cities { get; set; }

protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)

{

base.OnConfiguring(optionsBuilder);

optionsBuilder.UseSqlite("Data Source=Test.db");

}

internal class City

{

public int Id { get; set; }

}

/// <summary>

/// Interaction logic for MainWindow.xaml

/// </summary>

public partial class MainWindow : Window

{

private VirtualQueryableCollectionView view;

public MainWindow()

{

InitializeComponent();

Load();

}

private void Load()

{

var context = new TestContext();

if (File.Exists("Test.db"))

{

File.Delete("Test.db");

}

File.Copy(@"..\..\Test.db", "Test.db");

view = new VirtualQueryableCollectionView(context.Cities);

view.FilterDescriptors.Add(new FilterDescriptor("Id", FilterOperator.IsEqualTo, 123));

GV.ItemsSource = view;

File.Delete("Test.db");

}

The view loads data from Entity Framework context. Sometimes it may throw DB exceptions, they go to the global level (dispatcher).

I don't know how to handle such exceptions.

private void Dispatcher_UnhandledException(object sender, System.Windows.Threading.DispatcherUnhandledExceptionEventArgs e)

{

e.Handled = true;

}

See my test project: https://github.com/dermeister0/telerik-test

Run the app. Click on column sort icon. Resize window. Result - infinite loop of exceptions. RadGridView tries to measure itself, it gets count of records from VQCV, but the view throws exception.

couldn't change the theme by "Configure porject" menu

couldn't change the theme by "Configure porject" menu.

although I use theme based on implicit styles, it still cannot go to the second page to select which theme will be applied.

The "Theme button" also didn't show when you select the WPF window

I use visual studio 2017 - version 15.8.9 and windows 10.

Telerik control is 2018.3.1016

VerticalLinearScale - change properties takes more than 20 seconds

I have VerticalLinearScale with properties:

Min= 0

Max = 100

MajorTickStep = 20

MiddleTicks = 4

by click on button I changed the values of the properties to:

Min= 0
Max = 30000
MajorTickStep = 5000
MiddleTicks = 10

the problem is that it takes too much time till the element render again with the new values

I couldn't attach the sample

Xaml is:

click event is:

private void Button_Click(object sender, RoutedEventArgs e)
{
bar.Min = 0;
bar.Max = 30000;
bar.MajorTickStep = 5000;
bar.MiddleTicks = 10;
}

Thanks,
