As of 2024 Q4 (November), we will deprecate the .NET 7 distribution. This decision is rooted in our dedication to align with Microsoft’s recommended framework versions so that our products leverage the latest advancements in technology, security, and performance.
We are aligning our product with Microsoft’s lowest-supported framework versions for .NET Framework and .NET, respectively. Please refer to the following blog post: Product Update for Enhanced Performance and Security

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.

if (cell != null)
{

position.MoveToDocumentElementStart(cell.Blocks.First());
DocumentVariableField docVariable = new DocumentVariableField() { VariableName = "5000" };
editor.InsertField(docVariable);
}
doc_text.Document.DocumentVariables["5000"] = "";
var field = doc_text.Document.EnumerateChildrenOfType<FieldRangeStart>().Where(x => x.Field.FieldTypeName == "DOCVARIABLE"

if (field != null)
{
doc_text.UpdateField(field);
}
// Add the Datepickers
var hrow5 = table.EnumerateChildrenOfType<TableRow>().ToList()[5];
var hrow6 = table.EnumerateChildrenOfType<TableRow>().ToList()[6];
var hrow17 = table.EnumerateChildrenOfType<TableRow>().ToList()[17];
AddPurchaseDatePicker(table, hrow5);

}
catch (Exception e)
{
CGlobals cg = new CGlobals();
cg.ShowError("TemplateHandler:PurchaseTemplate Error\n" + e.Message, 3);
}
}
We are then trying to insert a DateProperties into 3 cells in the table created using AddPurchaseDatePicker(Table, TableRow) :
public void AddPurchaseDatePicker(Table table, TableRow row)
{
try
{
RadDocument document = doc_text.Document;
RadDocumentEditor editor = new RadDocumentEditor(document);
var dateCell = row.Cells.ToList()[1];
DocumentPosition position = new DocumentPosition(document);
string dateVal = string.Empty;
var span = dateCell.EnumerateChildrenOfType<Span>().FirstOrDefault();
if (span != null)
{
dateVal = span.Text;
span.Text = " ";
}
position.MoveToDocumentElementStart(dateCell.Blocks.First());
document.CaretPosition.MoveToPosition(position);
editor.ChangeFontFamily(new FontFamily(CGlobals.docu_default_font));
editor.ChangeFontSize(Unit.PointToDip(CGlobals.docu_default_font_size));
DateProperties dataProperties = new DateProperties();
try
{
dataProperties.FullDate = DateTime.Parse(dateVal);
}
catch { }
dataProperties.IsTemporary = false;
dataProperties.StyleName = "TemplateFields";
editor.InsertStructuredDocumentTag(dataProperties);
doc_text.Document = document;
table.Rows.ElementAdded += doc_text_NoteChanged;
}
catch { }
}
When we try and set the CaretPosition with
document.CaretPosition.MoveToPosition(position);
we recieve the following exception:
System.InvalidOperationException
HResult=0x80131509
Message=inline does not belong to this document.

We are using a similar method to add DateProperties in other generated documents without problem, e.g.:
public void AddNotesDatePicker(Table table, TableRow row)
{
try
{
RadDocument document = doc_text.Document;
RadDocumentEditor editor = new RadDocumentEditor(document);
var dateCell = row.Cells.ToList()[0];
DocumentPosition position = new DocumentPosition(document);
string dateVal = string.Empty;
var span = dateCell.EnumerateChildrenOfType<Span>().FirstOrDefault();
if (span != null)
{
dateVal = span.Text;
if(String.IsNullOrEmpty(dateVal) || dateVal == " " )
{
dateVal = DateTime.Now.ToString("dd/MM/yyyy");
}
span.Text = " ";
}
position.MoveToDocumentElementStart(dateCell.Blocks.First());
document.CaretPosition.MoveToPosition(position);
editor.ChangeFontFamily(new FontFamily(CGlobals.docu_default_font));
editor.ChangeFontSize(Unit.PointToDip(CGlobals.docu_default_font_size));
DateProperties dataProperties = new DateProperties();
dataProperties.FullDate = DateTime.Parse(dateVal);
dataProperties.IsTemporary = false;
dataProperties.StyleName = "TemplateFields";
editor.InsertStructuredDocumentTag(dataProperties);
doc_text.Document = document;
table.Rows.ElementAdded += doc_text_NoteChanged;
}
catch { }
}

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 was playing around with RadTreeMap and was able to show some data. I decided to move the newly classes for data and viewmodels around the project to the suitable locations. Now my TypeDefinitions can't recognize the names I am passing in. What's the format? How to point RadTreeMap TypeDefinition's TargetTypeName to a type in different namespace? And if that type lives in another Assembly f.e?

hello
I used desktop alert. The height of my desktop alerts is different, and the sum of their height is sometimes higher than the height of the monitor. User closes Desktop Alert
And then it scrolls automatically and the rest is displayed.
1. How can I find out which Desktop Alert is being viewed by the user on the monitor and which Desktop Alert is not visible due to the large number of Desktop Alerts? Sometimes I want to close all the desktop alerts that the user sees on the monitor so that the rest is displayed, and so on.
2. If the number of desktop alerts is large and their total height is greater than the height of the monitor, is it possible to display the scroll so that the user can see the entire desktop alert by scrolling?

Our application has a RadVirtualGrid that can be much wider than the window (so it scrolls). Our SelectionUnit is set to "Row". But when I hit Ctrl + End the grid not only jumps to the last row, but also scrolls the last column into view. It seems to me that if the SelectionUnit is "Row" the control should just jump to the last row and not change the column or scroll status at all. I guess the same thing is true about ctrl+Home to go to the top. Anyone agree?
Thanks!
