Hi,

  Does anyone has a sample of a Wind Rose done in WPF using the Polcar Chart ?

Thanks

1. I find GridViewCheckBoxColumn far too dull - the difference between checked and unchecked is not obvious enough when it's not active.  Is there an easy way to punch it up?
2. I'd like the functionality of GridViewSelectColumn, but from what I've been able to determine, it isn't really intended to be used with MVVM.  The documentation says explicitly that "GridViewSelectColumn does not bind to data".  Am I missing something?

Thanks!

Brad.

I'm using a DefaultVisualStyle Property to set the style in order to control the Fill color of ScatterPointSeries via the DataItem.PointColor property (as seen below)

This works fine, but when I try to use a ChartDataSourceStyle to reduce the number of datapoints using Index-based sampling, something breaks and I no longer see ANY points displayed in the graph, due to this binding failure:

** How can I redirect the DataPointSamplingInfo points to use the PointColor of its DataItems (they'll all have the same value) **

<Style x:Key="ScatterPointStyle" TargetType="Path" >
            <Setter Property="Fill" Value="{Binding RelativeSource={RelativeSource Mode=Self}, Path=Tag.DataItem.PointColor}"/>
</Style>

  <telerik:ChartSeriesProvider Source="{Binding ChartData}"  >
      <telerik:ChartSeriesProvider.SeriesDescriptors >

Hi 

I've been using the Microsoft WebView2 control lately and find it quite horrible to work with... 

I was wondering if you guys at Telerik would be able to make a wrapper for it that improve the functionality of the control ? 

Problems that i encountered : 

- Initialization is pretty messed up and require that you setup a Rube Goldberg machine to make it work.

- Overflow issues : the Webbrowser may overflow any / all other WPF controls unless you do a lot of scorcery ... 

- Having the WebView inside a scrollbar is pretty messed up with overflow issues all over.

Hi,

Is there a way to change the icon for the rad expander from the circle with a '<' or '>' to an icon and shape that I define?

Thanks

Tony

I'm sure this is trivial, but I've been unable to find the answer.  I have a RadGridView defined as follows:

<telerik:RadGridView
    ItemsSource="{Binding Products}"
    SelectedItem="{Binding SelectedProduct, Mode=TwoWay}">
    ...
</telerik:RadGridView>

However, when I change the "SelectedProduct" programmatically, the RadGridView doesn't show that highlighting.  What am I doing wrong?

Hey,

I am using a DragDropManager to drag images from a itemscontrol onto a table.
Now I want to rotate the image, if the user presses the Key "R" during Dragging.

But I dont get it to work.
All Input Bindings on the Window and DataTemplate did not fire.
Does anyone have an idea to achieve what I want?

DragDropManager.AddDragInitializeHandler(icImages, OnDragInitialize);

private void OnDragInitialize(object sender, DragInitializeEventArgs e)
        {
          
            clsImage imageData = (clsImage)((FrameworkElement)e.OriginalSource).DataContext;

            DragDropData dragData = new DragDropData
            {
                ImageData = imageData ,
                Column = Column
            };

            e.Data = dragData;
            e.DragVisual = new ContentControl { ContentTemplate = LayoutRoot.Resources["ImageTemplate"] as DataTemplate, Content = imageData };
            e.AllowedEffects = DragDropEffects.All;

            e.Handled = true;
        }

            <DataTemplate x:Key="ImageTemplate">
                <Grid>
                    <telerik:RadSvgImage
                        UriSource="{Binding file}"
                        HorizontalAlignment="Left"
                        SizeType="ContentToSizeStretch"
                        OverrideColor="{Binding ImageColor}"
                        />
                </Grid>
            </DataTemplate>

I ran into this problem when experimenting with VirtualGrid, but trying to work with Multiple selection mode seems completely broken. I have even created a new project from scratch and only imported the following packages:

telerik.windows.controls.for.wpf.xaml (2024.3.924)
telerik.windows.controls.virtualgrid.for.wpf.xaml (2024.3.924)

My MainWindow.xaml looks like:

<Window x:Class="TestVirtGrid.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:TestVirtGrid"
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" 
        mc:Ignorable="d"
        Title="MainWindow" Height="450" Width="800">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="*"/>
            <RowDefinition Height="50"/>
        </Grid.RowDefinitions>
        <telerik:RadVirtualGrid x:Name="VirtGrid" CanUserEdit="False" Grid.Row="0" SelectionMode="Multiple" SelectionUnit="Row" />
        <Button Grid.Row ="1" Content="amon"/>
    </Grid>
</Window>

The code-behind looks like:

using System.Collections.ObjectModel;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using Telerik.Windows.Controls.VirtualGrid;

namespace TestVirtGrid
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();

            ObservableCollection<Test> list = [];
            for (int i = 0; i < 20; i++)
                list.Add(new Test() { a = i, b = i });
            VirtGrid.DataProvider = new DataProvider(list);
        }

    }
    public class Test
    {
        public int a { get; set; }
        public int b { get; set; }
    }
}

When running the application, I'm able to select rows, but deselecting is clearly not working as intended. When I try to deselect, it often just completely fails to do so. Sometimes (like, 1 in 5 tries?) it does end up deselecting the row.

If there's something I've done wrong here, please let me know, otherwise I'd like to get some confirmation that this module doesn't work.
