When you resize (but only decreasing size) the control, the position and size of the Marker indicator is not updated. 

This is reproducible with RadVerticalLinearGauge and VerticalLinearScale. When the RelativeHeight of the scale is set to 1 and the RelativeY is set to 0.

As a work around you can avoid setting the RelativeHeight and RelativeY properties of VerticalLinearScale.

Users reported that the Text Search feature is misbehaving for certain columns in their grid.

We found that that if we take the Telerik example “DeferredSearching_WPF.sln", and change the "int" field+property to "long" , text search for a number indeed falls over.

Can you reproduce this?

Kind regards, Bertus Distributie ICT

When Depth property is set it is expected that the undo stack would not keep more items than the depth value. However, this behaviour is not working in ImageHistory class and could lead to OutOfMemoryException when the stack gets full of ImageHistoryItem instances.

Steps to reproduce:
1. Open ImageEditor and load some image.
2. Set ImageEditor.History.Depth = 1.
3. Make a few rotations.
Expected: When making Undo you should be able to undo only the last rotation.
Actual: You can Undo all the rotations meaning that Depth property is not respected.

The exception is thrown for the RotationAngle property.

The issue can be observed also in the opposite direction - the diagram is serialized on a machine with some culture (for example Portugal Porguese - pt-PT) and then restored on a machine with an English culture.

The issue reproduces only when saving and loading between cultures which numeric separators are different. For example, with Bulgarian culture, the number 4.5 is represented as 4,5 (with a comma). With English culture the number will be represented as 4.5 (with a period).

To work this around, create a custom RadDiagramShape and override its Deserialize() method. Then parse the RotationAngle manually, and set it to the RotationAngle property of the shape. After this, set the RotationAngle of the SerializationInfo to null, in order to prevent the default restoring of the property.

public partial class CustomShape : RadDiagramShape, IEquatable<BaseShape>
{
    public override void Deserialize(SerializationInfo info)
    {
        if (info["RotationAngle"] != null)
        {
            var angle = Convert.ToDouble(info["RotationAngle"].ToString(), CultureInfo.InvariantCulture);
            this.RotationAngle = angle;               
            info["RotationAngle"] = null;
        }
        base.Deserialize(info);
    }

Hello.

I've created buttons that are bound to FileDialogCommands for sending commands to an ExplorerControl, as shown here:

https://docs.telerik.com/devtools/wpf/controls/radfiledialogs/features/commands

 

Everything works when the ExplorerControl is visible.  However, if the ExplorerControl's Visibility is set to Collapsed (which I need based on a condition), the Command bindings on the buttons throw the below error:

System.NullReferenceException: Object reference not set to an instance of an object.
   at Telerik.Windows.Controls.FileDialogs.ExplorerControl.CanExecuteHelper(Object sender)

 

The UserControl that hosts the ExplorerControl is being imported through MEF.  I don't know if that's a factor.

Either way, it looks like a null check might be needed for the InternalViewModel property.

A useful new control would be : RadWebcam

It would show webcam view in realtime and call a function each x seconds (or ms), would be useful for :
 - user picture to attach to its user account
 - quick product picture
 - and for my need : call an external function for barcode recognization

I think it would be easy and fast to create this control for WPF, and it would fit perfectly with Silverlight 4 (or 5 ?) webcam support.

In that way it will be easily modified through the palette of themes such as Windows8, Windows8Touch, Office2013 and VisualStudio2013 and it won't be needed to overwrite the whole template. That feature is very important for users with visual impairment or where low contrast screens are used.

The exception is thrown by the SystemFontsManager internal class from Telerik.Windows.Documents.Core, so it can observed when using RadPdfViewer, RadRichTextBox, RadSpreadsheet.

The reason is not clear, posssible causes are:
- Corrupted fonts after upgrade from Windows XP
- Enabling of Block untrusted fonts feature (https://docs.microsoft.com/en-us/windows/threat-protection/block-untrusted-fonts-in-enterprise )

The call stack is as follows:

System.TypeInitializationException: The type initializer for 'Telerik.Windows.Documents.Core.Fonts.SystemFontsManager' threw an exception. ---> System.IO.FileNotFoundException: Unable to find the specified file.
   at MS.Internal.Text.TextInterface.Native.Util.ConvertHresultToException(Int32 hr)

   at System.Windows.Media.Fonts.TypefaceCollection.<GetEnumerator>d__11.MoveNext()
   at Telerik.Windows.Documents.Core.Fonts.SystemFontsManager..cctor()

Workaround: 

Manually delete all registry key values in Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts pointing to files outside of the Fonts folder.

In some cases when an image is copied from an external source and pasted in the rich text box, the image is not displayed. This is caused by the Clipboard.GetImage() method used internally by the control. 

To work this around, you can subscribe for the CommandExecuting event of RadRichTextBox and manually get the image from the clipboard.

private void Rtb_CommandExecuting(object sender, Telerik.Windows.Documents.RichTextBoxCommands.CommandExecutingEventArgs e)

{
	PasteCommand command = e.Command as PasteCommand;
	if (command != null && (Clipboard.GetData("DeviceIndependentBitmap") != null))
	{
		//Get the image stream from the clipboard.
		//You can check the following blog post for an approach which you can use to get the image properly:
		//https://www.thomaslevesque.com/2009/02/05/wpf-paste-an-image-from-the-clipboard/
		this.radRichTextBox.InsertImage(imageStream, "jpeg");
		e.Cancel = true;
	}
}

The idea of this feature is to introduce a form, which can host tabs in its title bar (like RadTabControl), just like in Chrome/Edge. This would allow our clients to deliver a modern and flexible layout to their users.

This happens only in scenarios when the widget has On state appearance defined and Off state appearance missing. If both appearances are missing then RadPdfViewer recalculates the appearances and the checkbox is successfully selected and deselected.
