Workaround: 
The vsdiffmerge.exe merge tool in Visual Studio 2017 is usually located here: C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer. You will need to create one additional folder named Ide inside the Team Explorer folder Then you can copy the vsdiffmerge.exe file from the Team Explorer folder to the newly created Ide folder. You can check the attached vsdiffmerge-path.png screenshot.

Then you can create the environment variable like this:
Variable name: VS120COMNTOOLS
Path: C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\IDE

After a project, built with the standard MS controls, is successfully converted to a Telerik WinForms project, the subscriptions to certain events available in the Designer.cs file may disappear if you open the design view and make some changes. A solution for this behavior is described in the How to Deal with Disappearing Event Handlers after Opening the Designer for a Converted WinForms Project KB Article.

If you fill a WrapLayoutPanel with some content and set it to the ViewPort property of the RadScrollViewer, you will notice that RadScrollViewer will not scroll the panel correctly.

To reproduce: 
1. Use the following code snippet:
public class ViewModel:INotifyPropertyChanged
{
    public ViewModel()
    {
    }

    private bool _isShown;

    public bool IsShown
    {
        get
        {
            return this._isShown;
        }
        set
        {
            this._isShown = value;
            OnPropertyChanged("IsShown");
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;

    protected void OnPropertyChanged(string propertyName)
    {
        PropertyChangedEventHandler handler = PropertyChanged;
        if (handler != null)
            handler(this, new PropertyChangedEventArgs(propertyName));
    }
}

2. Add a MS Panel and a RadPanel to the form.
3. Add Panel.DataBindings at design time for its Visible property to the ViewModel.IsShown property.
4. When you run the application, the MS Panel is not visible. However, if you remove the RadPanel it is shown. Please refer to the attached sample video illustrtaing better the performed steps.

After revamping the documentation for the Telerik UI for WinForms product, the following problems occurred:

1. Search for a specific class or method in the search box in the following site: https://docs.telerik.com/devtools/winforms/introduction. Select one of the results referring to the API documentation. As a result you will be navigated to the main page of the API reference instead of to the respective class or method. Refer to the Problem1.gif file. It seems that the search results from the API reference return old links for the previous API link pattern.

2. The search box in https://docs.telerik.com/devtools/winforms/api/ is significantly lagging while typing. We should consider performing the search operation after pressing Enter and not with each keystroke. Please refer to the Problem2.gif file.

3.  When you scroll the navigation view on the left side to a certain position and select an article, the vertical scrollbar sometimes gets reset to the top position and you have to scroll back.  (Note that this problem is not reproduced each time).

At the moment, RadCalculatorDropDown allows displaying a calculator only in a popup editor. The new control should allow placing a calculator on a form or a user control.

Hello,

The Toast Notification is similar than the MessageBox, but not block the UI with an "always on top" dialog and dont have a dialogresult return value. This is only a text message, that shown, and hides after specified second. I can set the text, the background and foreground color, the container control and the alignment of the notification. I use this control to interact with the user, but not disturb his work. 

Example messages:
"The table saved successfully!"
"Refresh done."
etc..

The color can define also the type of the message:
Green -> OK
Red -> Error
Yellow ->Warning
Blue -> Information
...

Thanks!

Best Regards,
László
