Improve performance, when calculating the positions of Smart Labels.

Add only a RichTextEditorRibbonBar without any other control on the form. If you run the application you will notice that it loads more than one second. We should investigate if it is possible and how to improve the initialization time.

To reproduce: 

System.Runtime.InteropServices.ExternalException (0x80004005): A generic error occurred in GDI+.

Good morning.

I'm using a pdfViewer instance in order to load pdf forms, with text fields to be edited by the users.

Loading is ok, editing is ok, the problem is when I go to save the edited document. When I save the document, if I don't click elsewhere in the document, in which case the content of the field is committed, the content of the field is not saved with the document. This happens either using the 'Save As' button or using the SaveDocument API function.

Probably it is my fault, since I'm new to PdfViewer: I can imagine that something like a commit command has to be available, but I'm not able to find it.

Can you help me, please?
Thank you in advance.

PS. I will attach three screenshots in order to let you understand better what I mean.

Run the attached project.
Expected: 
10 points on each row.
Actual:
There is a seemingly random number of points on each row:

Hi Telerik Support,

Here is a description of the environment I work with:

- Visual Studio 2019 (version 16.9.3)

- NuGet package is UI.For.Winforms.AllControls.Net50 (v2021.1.326)

- Project is a .NET5.0 class library.

When trying to add a RadDropDownListElement to a RadRibbonBarGroup, Visual Studio seems to encounter an error and a window pops up with the message "The connection to the server has been lost". Adding other types of elements to the RadRibbonBarGroup seems to work properly (I managed to add buttons without any issues).

I will attach a screenshot of the issue.

Thanks for your help !

Good-day,

I am trying to export a RadDiagram to an SVG Image, I would like to find out if it is possible to do so and how to do it.

I look forward to hearing from you.

Regards,

Tanaka

Steps to reproduce:

1. Copy an image with a transparent background to the Clipboard

2. Paste it in RadPictureBox.

As a result you will notice that the transparency is lost.

Note: it is possible to handle clicking the Paste menu item and control what image exactly to be pasted:

        public RadForm1()
        {
            InitializeComponent(); 

            this.radPictureBox1.ContextMenuItemClick += RadPictureBox1_ContextMenuItemClick;
        }

        private void RadPictureBox1_ContextMenuItemClick(object sender, HandledEventArgs e)
        {
            if (sender == this.radPictureBox1.ContextMenuProperties.PasteItem)
            {
                e.Handled = true;
                // Image extractedImage = // get image with transparency; 
                // this.radPictureBox1.Image = extractedImage;
            }
        }

My BreadCrumb that was linked to my TreeView worked for a while and then I got this error:

You cannot add or insert the term in more than one place.  You must first remove it from its correct location or clone it.

I deleted the BreadCrumb and my program worked again. 

I tried later to add back it in.   The program wouldn't run at all (No error messages).   I tried just adding the BreadCrumb control and not attaching it to anything.  It still wouldn't run.  I deleted the BreadCrumb and the program runs again.

I tried making a new program with just a BreadCrumb and a TreeView.   When I ran it.  It when right away into Break Mode.

I did your tutorial where you used a BreadCrumb with TreeView.  Same thing.  The program went immediately into Break Mode.

You can also note it in demo application with this settings:

We are designing our application at design time. All changes to the button elements are done in the designer. However, the ImagePrimitive.MinSize property gets reset after a new resource image is added.

Please refer to the attached gif file.
