Just installed UI for WPF Q1 217 SP1 and received this error.

error MC3080: The property 'DataFormValidationSummary.Errors' cannot be set because it does not have an accessible set accessor.

We have been using the DataFormValidationSummary outside of the DataForm for years.  This is a serious breaking change for us.  Can you provide a work around?

Thanks in advance,

Steve

Hi,

I have a GridView for a DesktopAlert. It is like the example in your demos. 

For the grouping by email received datetime I have used the same example: 

It works succesfull, however the format of the group header is "mm/dd/yyyy" and I need other date formart. 

How do I change the date format string?

Thanks!

Hi,

is there a way to prevent the vertical weekview from showing horizontal scrollbars by narrowing the groupheaders to the available space? I also realized, that when you put a lot of appointments into one slot, this group gets more space than the others.

What I want is, that every column has the exact same width and they use only the space available in the current window without horizontal scrolling.

Thanks

Recently, when we enabled UI virtualization for RadTreeView in our application, our icons for the RadTreeViewItems disappeared.

We set the icons (DefaultImageSrc) in DataTrigger setters in a style, as follows:

This is with UI for WPF v. 2015.2.0401

It looks like this is the known bug described here and here.   That is, the problem is that DefaultImageSrc is non-functional in virtualized trees.

1) Can I get a confirmation that this bug is indeed causing our difficulty, please?  Is there anything else you see that would cause it?

2) It looks like you all have declined to fix this bug in the past.  Still declining? :)

3) I could recommend that the documentation for UI Virtualization with RadTreeView here be updated, please, to to include some very obvious notes, a) that enabling virtualization will disable DefaultImageSrc and ExpandedImageSrc (and any other TreeView features that don't work with virtualization?), and b) that workarounds are necessary.

Thanks!

Hi! I develop Prism 6 WPF MVVM application. I defined an ObservableCollection instance in Model, please see below:

public class DeviceStatusModel
    {
        #region Constructors
        public DeviceStatusModel()
        {
            SeriesData = new ObservableCollection<short>();
            SeriesData.Add(20);
            SeriesData.Add(30);
            SeriesData.Add(50);
            SeriesData.Add(10);
            SeriesData.Add(60);
            SeriesData.Add(40);
            SeriesData.Add(20);
            SeriesData.Add(80);
        }
        #endregion

        #region Properties
        public ObservableCollection<short> SeriesData { get; set; }
        #endregion
    }

Then in ViewModel I defined the property of type of DeviceStatusModel. Please see below:

    public class DeviceStatusViewModel : BindableBase
    {
        #region Fields

        private DeviceStatusModel _deviceStatusModel;

        #endregion

        #region Constructors

        public DeviceStatusViewModel()
        {
            this.DeviceStatusModel = new DeviceStatusModel();
        }

        #endregion

        #region Properties

        public DeviceStatusModel DeviceStatusModel
        {
            get { return this._deviceStatusModel; }
            set { this.SetProperty(ref this._deviceStatusModel, value); }
        }

        #endregion
    }

Then in View I wrote the next XAML, please see below:

<UserControl x:Class="DeviceStatus.Views.DeviceStatusView"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:prism="http://prismlibrary.com/"             
             xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"             
             prism:ViewModelLocator.AutoWireViewModel="True">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition/>
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition/>
        </Grid.ColumnDefinitions>

        <telerik:RadCartesianChart Grid.Row="1" Grid.Column="0" HorizontalAlignment="Left" Margin="6,7,0,0" VerticalAlignment="Top">
            <telerik:RadCartesianChart.HorizontalAxis>
                <telerik:LinearAxis/>
            </telerik:RadCartesianChart.HorizontalAxis>
            <telerik:RadCartesianChart.VerticalAxis>
                <telerik:LinearAxis/>
            </telerik:RadCartesianChart.VerticalAxis>
            <telerik:ScatterLineSeries ItemsSource="{Binding DeviceStatusModel.SeriesData}"/>
        </telerik:RadCartesianChart>

    </Grid>
</UserControl>

And eventually when aplication runs I see only next poor picture, please see "ChartViewScreenShot.PNG" file attached.

Hi!
Is there a way to _not_ enter the edit mode if the user changes the selected cell using the arrow keys or by pressing enter?
(Event if the user was in edit mode before). I want to get closer to the behavior of excel.
