When focusing a Rad Controls like RadDateTimePicker, the watermark is hidden. This behavior could be very problematic when this field is the first of a form. The user will never see the watermark because the focus will be set in this field when entering in the form. It would be nice if the watermark could just be less visible by lowering its opacity. Additionaly, if the user erases the text, it would be nice too if the watermark could be showed at the same visible state than explained above.

When MainView.xaml is opened, the designer throws NullReferenceException because the SelectedOutlookSection is not initialized.

Workaround: If SelectedOutlookSection is null, then initialize it to point to the first item from the collection of outlook sections:

public OutlookSection SelectedOutlookSection
{
    get
    {
        if (this._selectedOutlookSection == null)
        {
            this._selectedOutlookSection = this.OutlookSections.FirstOrDefault();
        }

        return this._selectedOutlookSection;
    }
  ...
}

The fix is available in R1 2017 SP1.

The issue is also observable in the Outlook project template as well - in the NewEmailWindow. As a workaround, the ScreenTip can be removed by deleting the following code:
telerik:ScreenTip.Icon="{telerik:IconResource IconRelativePath=FontDialog.png,IconSources={StaticResource IconSources}}"  

Fix available in R3 2018 SP1 release.

Please, provide official Russian Localization for, at least, WPF products. This is the only question, why customers chose other providers than Telerik. For example, I like Telerik WPF controls more, but me head at work bought other WPF-vendor because they provided official Russian Localization. Thanks.

This blends the text with the background and only a black rectangle is displayed. See the attached image.

Allow to define ChartGrid for axis, not for chart.
Every Axis can draw our grid lines.
Chart.Grid can be a wrapper for Chart.Horizontal and Chart.Vertical axes.

I have a Winforms application (Very Large so there is no changing it any time soon) that launches a WPF window with a .show(). In this WPF window I have radDocking. In one of the RadPanes I have a WPF TextBox. As long as the RadPane is docked the TextBox will receive text. However, if I undock, the TextBox will no longer receive text input.
I do not see this issue, however, when launching the WPF window in my WPF test app.

Please let me know if there is some kind of work around for this issue.

I have attached a test app that I have created which will demonstrate the issue. You will have to point the "TextBoxInRadPanel"  to your Telerik DLLs, they were too big to attach.

Repro Steps:
1. Launch the HostApp
2. Click the "Press Me" button
3. Type into the TextBox in the docked "UC Test" RadPane - input is received
3. Undock the "UC Test" RadPane
4. Attempt to type into the TextBox area - no text input will be received.

Hi,

in your UI for WinForms Suite is a control called CheckedDropDownList. This control is just awesome so why it doesn't exists as WPF Version? Yesterday I was in need to create a close one with a AutoCompleteBox and a Button for drop down the list. But this isn't exactly what I need and it feels a bit...unperfect.

So please create this great control for WPF! :)

Deliver an icon library which can be easily used in the user's application.
