This can be reproduced if you place a ComboBox in the RowDetailsTemplate which selection is bound to a property of the data row's model. Changing the selection in the ComboBox for one row and then expanding another row, will set the selection property of the previous row model to the value from the new model.

Hi friends,


  my custom tooltips never work on the first bar only of the BarSeries, here is a simple example showing this behavior.  There is important data for me in that column, so let's hope it's possible to resolve this.  Many thanks!

Remove the space reserved for the sort indicator in the column header, when CanUserSort is False and therefore the sort indicator is not displayed. The current behavior prevents the user to easily center the header text.

To work this around, you can edit the ControlTemplate of DataGridColumnHeader. In the template, you can update the Visibility of the TextBlock with x:Name set to "SortIndicator" when CanUserSort is False.

If you change the current date and then click on the time segment of the control that allows you to select the time, the date segment is lost. The opposacite is true also - the selected time is lost if you click in the date segment.
To set the correct DateTime, you should first select the date or time, click OK, open the drop down again, select the other component (date or time) and click OK again.

Type: Bug Report


  I am planning to build one of the pages of my software around the amazing Timebar control but I experience many issues.  With this code:

<Grid Height="200">
    <tcontrols:RadTimeBar x:Name="timeBar" Height="150">
            <tdataViz:YearInterval />
            <tdataViz:MonthInterval />
            <tdataViz:WeekInterval />
            <tdataViz:DayInterval />

            <tdataViz:RadLinearSparkline x:Name="timeSparkline"/>
Many issues happen:

1. The control crashes if the height is too small
2. The control crashes in Visual Studio hot Reload if one of the width or height is changed (so the value becomes 0 or small when the int number is deleted or changed)
3. The control crashes the software if my MainWindow automatically navigates to a page with the TimeBar control in it.  (Frame.Navigate(typeof(Views.PageWithTimeBar));).  The workaround was to add a 200ms delay in the page load...
4. The control crashes if there is no width, so it prevents me to make it full width of my grid which is what I need to keep my software dynamically responsive.  Hard coding a width in the control defeats the purpose of the Grid layout auto width capabilities and will be a problem with devices with different resolution.

The TimeBar is really an amazing and very original control.  I have bought Telerik in big part for it, I really hope that you will be able to address these issues quickly as my software launch date is approaching.  Thank you very much!

Hi Support


I'm using RadDataGrid on several pages in my application. There a pages where the scrollbar does not appear. On some pages it works.

The structure of the pages is similar. What are your suggestions to look for.

The touch pointer capture is never released when you swipe an item in order to show its swipe content. Because the touch capture is never released, the pointer released action is never fired and the drag/drop operation cannot finish. This leads to glitches in the item. Clicking in swipe content can make it disappear. Also, if you are on a device that support both mouse and touch, you can notice the issue by swiping with touch and then mouse move. The mouse/touch device is captured and you will see that item moves on mouse move even if the left button is not pressed.

The length of the LinearBarGaugeIndicator visual (representing the featured measure) is wrong when the RadBulletGraph is hosted in a RadDataGrid cell (via the DataGridTemplateColumn).

No form controls are visible when running the program.  Problem affects about half of users

Setting the MaxValue, MinValue and Value properties at runtime doesn't work when the settings are done in the Opened event handler of RadDatePicker. The DateTime values of the properties are updated as expected, but this is not reflected in the UI.

To work this around, you can use the Click event of the internal DateTimePickerButton, instead of the Opened event.

private void DatePicker_Loaded(object sender, RoutedEventArgs e)
	var btn = this.datePicker.FindChildByType<DateTimePickerButton>();
	btn.Click += Btn_Click;            

private void Btn_Click(object sender, RoutedEventArgs e)
	var vm = (MainViewModel)this.datePicker.DataContext;
	this.datePicker.MinValue = DateTime.Today;

The following exception is thrown when expanding row details with a height larger than the row height:

ArgumentOutOfRangeException: "Non-negative number required."

The group header row overlaps the column headers when scrolling to a column that is out of view upon previously resizing the window and the GroupHeaderDisplayMode is Frozen.

Expanding the row details when the rows have variable heights offsets the scrollbar and brings the expanded row out of view.

Release 2.2.0

"Processing Resources failed" compile-time error is thrown when the following nuget packages are referenced together:

- Telerik.ReportViewer.WinUI
- Telerik.WinUI.Controls

It is enough only to reference the packages and try to build the project.

The error appears also if you try to reference the .dll instead of nuget packages. But only in case the Telerik.WinUI.Controls.dll file is not referenced from the installation folder of the Telerik Reporting product.

Error details:

1>WINAPPSDKGENERATEPROJECTPRIFILE : error : PRI175: 0x80073b0f - Processing Resources failed with error: Duplicate Entry.
1>WINAPPSDKGENERATEPROJECTPRIFILE : error : PRI222: 0x80073b0f - Unspecified error occurred.
To resolve this, download the Telerik dlls deployed with the Reporting product and reference them from the same folder, instead of using the nuget packages.
