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).

Use attached to reproduce inside VisualStudio 2017.

1. Run "1342574 ListControl" project
2. Add CodedUI test in "1342574 CodeUISample" project. ("Record actions, edit UI map or add assertions" option)
3. After starting recording, click inside radGridView cell, type something and click Tab.
4. Pause and Generate Code.

After running the recorded CodedUI test and you will see that it clicks on the grid cell but does not type any text.

Note that the issue is not reproducible in VS 2012.

How to reproduce: store an image on the file and try to use it this way
string path = @"D:\img.png";
this.radLabel1.Text = "<html><img src=" + path + "><b>Test</b></html>";

Workaround: if possible embed the image in the assembly and use it as a resource
this.radLabel1.Text = "<html><img src=res:_1133506_RadLabelLinkHtmlLike.img.png><b>Test</b></html>";

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)
        {
            base.DpiScaleChanged(scaleFactor);

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

                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!
                }
                else
                {
                    RadPageViewPage page = this.Owner.SelectedPage;
                    this.Owner.SelectedPage = this.Owner.Pages[0];
                    this.Owner.SelectedPage = page;
                }

CASE 2:
 public partial class RadForm1 : Telerik.WinControls.UI.RadForm
    {
        public RadForm1()
        {
            InitializeComponent();
            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!

To reproduce: please run the application provided in the ticket. You will notice that RadGridView stops updating.

Workaround: use MethodInvoker for the update operation:

        private void readTicks()
        {
            DateTime now = DateTime.Now;
            Tick previouse = null;
            for (int i = 0; i < lines.Length; i++)
            {
                if (canceled)
                    return;

                var t = new Tick();

                try
                {
                    try
                    {
                        JsonConvert.PopulateObject(lines[i], t);
                    }
                    catch
                    {
                        continue;
                    }


                    var c = contracts[t.ContractId];
                    c.Row[(int)t.TickType] = t;
                    c.CurrentTickSetNr++;

                    if (this.radGridView1.InvokeRequired)
                    {
                        this.radGridView1.Invoke(new MethodInvoker(delegate { c.Fire(t); }));
                    }
                    else
                    {
                        c.Fire(t);
                    }

                    previouse = t;
                    OnTick?.Invoke(c.ConId, i);
                }
                catch (Exception e)
                {
                    Debug.WriteLine(e.Message);
                }
            }

            OnDone?.Invoke(this, new EventArgs());
        }

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:
