Project Upgrade Utility tries to write in project files that do not contain any Telerik references. However, only the files that contain Telerik references should be modified and saved.

If you are using span tag in cooperation with style attribute, the following html concat "Training Room B" string:

<html><p><i><span style="font-family: Microsoft Sans Serif;font-size: 13.3px;color: #C57300;">Welcome to RoBase</span></i><i><span style="font-family: Microsoft Sans Serif;font-size: 10.7px;color: #C57300;">,</span></i><span style="font-family: Microsoft Sans Serif;font-size: 11px;color: #000000;"> Please be aware that </span><span style="font-family: Microsoft Sans Serif;font-size: 11px;color: #C50000;">Training Room A</span><span style="font-family: Microsoft Sans Serif;font-size: 11px;color: #000000;"> will be off limits for the rest of the week for a much needed paint job. </span><b><span style="font-family: Microsoft Sans Serif;font-size: 11px;color: #008116;">Training Room B</span></b><span style="font-family: Microsoft Sans Serif;font-size: 11px;color: #000000;"> is still available and the Conference Room can be used if needed.</span><span style="font-family: Calibri;font-size: 16px;color: #000000;"><br /></span></p><p><span style="font-family: Microsoft Sans Serif;font-size: 11px;color: #000000;">See Linda to reserve it.

The color blending feature does not work if you try to use it in the constructor of a form. It works only if you set it at Form_Load or at a later moment.

This causes multiple controls updates which reduces the application performance. Having 3 labels will fire the event 45 times which will update the rest of the bound controls 45 times.

Telerik winforms demo application "bugtracker" issue:
1. drag the "bugs" window to touch the upper middle docking guide icon and without releasing the mouse button drag it further
Effect: please observe that the remainder of the "bugs window" will not be refreshed, you can draw with this window
The same issue can be also observed in the demo hub: drag > Tabstrip properties demo application and also in the DragDropService demo application.

1. Create a new form.
2. Add Panel
3. Change its ForeColor and Font properties
4. Drop a RadLabel inside, it will not change its Font and ForeColor properties.
Comment: this is not an issue. We changed our behavior in order to achieve consistent look regardless of the position of RadLabel. Now the theme defines the ForeColor and the Font of this control.

Poor support for custom DPI scaling in Windows 7 - Windows 10.
There no null checking, and there is dirty hacks:

CASE 1: RadPageViewElement
 public override void DpiScaleChanged(SizeF scaleFactor)

            if (this.Owner != null && this.Owner.Pages.Count > 1)

                if (this.Owner.SelectedPage == this.Owner.Pages[0])
                    this.Owner.SelectedPage = this.Owner.Pages[1]; // NO NULL CHECKING
                    this.Owner.SelectedPage = this.Owner.Pages[0]; // DIRTY HACK: users can have their own processing OnSelectedPage, which is unexpected here!
                    RadPageViewPage page = this.Owner.SelectedPage;
                    this.Owner.SelectedPage = this.Owner.Pages[0];
                    this.Owner.SelectedPage = page;

 public partial class RadForm1 : Telerik.WinControls.UI.RadForm
        public RadForm1()
            radWizard1.Pages.Add(new WizardPage()); // when user has 100% Dpi, this code works normally. But if user has custom scale DPI (e.g. 101%), user received System.NullReferenceException: 'Object reference not set to an instance of an object.' (because because again there is no verification for ContentArea = null)...

Please improve the work with custom DPI scaling!

Had radchartview with showtrackball = false, and a form checkbox to enable disable the trackball

So startup showtrackball = false, the start appl, all ok, mouse over chart, all ok,   then use checkbox to set showtrackball=true, then mouse over chart all ok, then use checkbox to set showtrackball = false (again) then mouse over - and get this crash!


System.NullReferenceException was unhandled

DECLINED: not an issue

To reproduce:
-add RadCommandBar with CommandBarDropDownButton;
-change its arrow direction:
this.commandBarDropDownButton1.ArrowPart.Arrow.Direction = Telerik.WinControls.ArrowDirection.Right;    

As a result there is one arrow to the right (correct) and another arrow image to the down direction (incorrect).

    private void Form1_Load(object sender, EventArgs e)
    this.commandBarDropDownButton1.ArrowPart.Image = null;

There is an issue in RadCarousel which can be reproduced by running the 'hi-res' code library article.
Last Updated: 20 Feb 2014 15:29 by ADMIN
Neither of the following set the shape of RadButton
this.radButton1.ButtonElement.Shape = shape;
this.radButton1.RootElement.Shape = shape;
this.radButton1.RootElement.ApplyShapeToControl = true;
The theme overrides the local settings.
Comment: RadButton uses an image to display its border. The image cannot be shaped and this causes the issue.
