When you start editing the input control, the watermark text should go on top of it or to the left.

Affects RadDateTimePicker control of TelerikWPFControls version 2015.1.1

When the user is typing in a specific date and time, the RadDateTimePicker control's text-to-date parsing doesn't accept an uppercase 'A' at the start of what it expects to be the month's name and automatically errors (displays a tooltip showing 'Error') as soon as an 'A' is input. This prevents the user from entering dates and times more specific than the clickable selection for the months of 'April' and 'August'. However, replacing the 'A' with a lowercase 'a' allows the user to proceed with entering more specific dates and times as normal without the 'Error' tooltip showing. 

E.g.: 
1) the user selects 03 April 2018 17:00:00 from the control's clickable selection of date and times;

2) they then try to type more specific minutes and seconds, e.g. 03 April 2018 17:45:23, but this is not accepted by the control and it displays the 'Error' tooltip;

3) workaround - the user changes 'A' of 'April' to a lowercase 'a', as in 'april'. Now the 'Error' tooltip goes away and the user is able to enter and save the more specific date time of 03 april 2018 17:45:23.

This bug only came to light once the control was live in production (released in January) and prevented our users from entering the specific trade date times necessary for regulatory purposes.

Can you tell me if this bug has been fixed in later versions of the control?

Thanks and regards,

I am attempting to use a ReleativeSource in my bindings in two places in a RadGridView:  1) the header of a column, and 2) one of the columns.  I am getting "System.Windows.Data Error: 4 : Cannot find source for binding with reference" in both cases.

I don't think I need to elaborate much, since https://www.telerik.com/forums/can%27t-find-the-right-ancestor-to-bind-to not only describes it perfectly, but also contains sample code from Telerik that, on my machine, fails the same way.

check the attach file,the gridview's droplist extend the screen area,
my screen is 2560x1440/175% DPI/14 inch/windows 10

Setting the TextWrapping to Wrap or WrapWithOverflow will not allow the WatermarkContent to be wrapped.

Reason for decline: 

Instead of setting the content inline, we recommend setting it as follows: 

<telerik:RadWatermarkTextBox Width="100">
	<telerik:RadWatermarkTextBox.WatermarkContent>
		<TextBlock TextWrapping="Wrap" Text="Watermark Content Watermark Content Watermark Content Watermark Content" />
	</telerik:RadWatermarkTextBox.WatermarkContent>
</telerik:RadWatermarkTextBox>

More information can be found in our help about using the WatermarkContent and WatermarkTemplate properties: https://docs.telerik.com/devtools/wpf/controls/radwatermarktextbox/features#using-the-watermarkcontent-property
Please let us know if this is not applicable in the scenario of your application.

In the current version of the WPF SDK Sample Browser Application it is really hard to track what's new and what control was updated. Even the version of Sample Browser by itself (2018.3) is not visible.

Maybe you remember the former Sivlerlight Online Demos (I'm not sure if it is still around but I cannot run it anymore because it needs IE11)? There was always an updated or new badge on the controls. So it was obvious what was new and updated.

I think this should be possible in WPF also.

When hovering with the mouse over the control panels there shoud be more information shown like date of the last update of the sample.

When clicking on a control on viewing the samples of the control, I can only open the folder, open in VS or run it. Sometimes it makes sense to open directly the sample on github to quickly check the version history.

The current workaround is to handle the Loaded event like so:

        private void RadMultiColumnComboBox_Loaded(object sender, RoutedEventArgs e)
        {
            this.combo.DropDownWidth = this.combo.DropDownMinWidth;
        }

The fix for this issue will be available with the next LIB (version 2018.3.1224) expected on Monday, December 24.

The underline types are compared by reference, causing mismatch and incorrect results.

Workaround: Use the UnderlineTypes static class to apply underlines.

Fix available in R3 2018 SP1 release.

When importing documents with destinations defined with zero-based page index, an invalid page is displayed when the destination is activated.

Non-breaking spaces are converted to plain spaces when importing docx documents. While non-breaking spaces are not fully supported by RadRichTextBox, this behavior is inconsistent with the behavior of all other formats, which preserve the nbsps on import and on export.

I would like the fluent theme to support spacing option like it does fonts. The Mail app added a new setting "Folder and message spacing" in which you can pick spacious , medium, or compact. I would like the fluent theme to support something similar.  The fluent theme was defined for "finger" access but we still have desktop apps that want dense information with mouse access.  I would normally just pick a different theme but because of Windows 10, I can't. Windows 10 no longer supports specifying a default font and WPF no longer defaults to the OS font. This means that all my Windows apps must support picking a font. So I'm stuck with the fluent theme. But I don't always want the "spacious" spacing that the theme uses.

Would it be possible to support picking "spacious", "medium" or "compact" spacing?

During the XAML export, by default images are serialized to XAML using the Convert.ToBase64String(byte[]) method. 

 Scrolling to a not visible column, a ToolTip appears on this column which does not have a ToolTipTemplate set.

When there are parentheses inside the arguments of a function call the expression parser cannot parse the expression e.g. Abs(1 - (2 * 3))

KeyTips are not displayed when trying to navigate between tabs very fast while the KeyTips of the Quick Access Toolbar being rendered.

As suggested in the orginal support ticket 1430154 I'm opening a separate bug reprot for the RadNumericUpDown control.

Visual Studio 2019 solution to reproduce the problem is attached to the bug report.

Current SDK Sample code supports only WPF 40.

Adding support for wpf45 will make more convenient way to work with Samples.

Sample dode can include new wpf 45 features

When using OpenStreetMaps with APIKey (required for Cycle and Transport variations)

the key is not automatically passed to the builtin minimap and it shows 'Api Key Required' in some tiles.
