MetadataType support

For the life of me I can't see what's wrong. I have a radgriview and I edit rowdetails with the raddataform. everything works great except the validation.
I am using the code below metadatatype (as an example) to add validation attributes to a class generated by EF. Obviously, this class is what I have bound to the dataform. I've stripped it to the bare min for this discussion.

The commented out code below shows a "buddy" class that I have implemented as a test to make sure the annotations are working. They are. If I have to create buddy classes and copy data for each returned record from a database query I will, but it seems rather a pain.

Any insight would be greatly appreciated. I read somewhere that this metadata thing is not support by you. Is this true? If so, what is the recommended way of getting the job done?

Thanks ... Ed

[MetadataType(typeof(CALMS_SamplesMetaData))]

public partial class CALMS_Samples: ValidatableBindableBase

{

}

public class CALMS_SamplesMetaData : ValidatableBindableBase

{

private string _clientSampleID;

[Required(ErrorMessage = "Required.")]

[MaxLength(50, ErrorMessage = "Exceeded 50 characters")]

public string ClientSampleID

{

get { return _clientSampleID; }

set { SetProperty(ref _clientSampleID, value); }

}

//public partial class CALMS_Samples : ValidatableBindableBase

//{

// private string __test1;

// [Required(ErrorMessage = "Required.")]

// public string test1

// {

// get { return __test1; }

// set { SetProperty(ref _cli_test1entSampleID, value); }

// }

//}

Installer Projects Extension + Localization of Telerik-Controls

Hello!

I am using the Installer Projects Extension for VS (Enterprise 2015) and having a problem with the localization-folders of the Telerik-Controls - they are not packed into the setup, so if I install it on other clients, there only will be the english localization of the controls.

Does anybody know the best-case to pack the (current) localization-files into the setup-project?

kind regards

RadGridView not editable

hi

I have a simple WPF project and an in-memory observable collection bound to it from here:
http://docs.telerik.com/devtools/wpf/controls/radgridview/populating-with-data/in-memory-date

The IsReadOnly property is set to False. When I click a cell it simply turns white (loses the content) and is read-only.

What am I missing here?

Regards,
Michael

Sorting a [NotMapped] column from QueryableEntityCollectionView

Hi,

I've binded a QueryableEntityCollectionView to a GridView. This works fine, except I'm unable to sort the [NotMapped] property in my model.
This property 'Age' is being calculated. The data is being shown correctly as long there is no sort defined.

I'm using EF for data layer.

Cheers!

Eric

Selecting ViewModels programmatically: race condition and UI problems

Hi,

I have several ViewModels linked to my RadDiagram; and some are children of others. I'd like that, when I select one, the children view models get selected as well so I can drag all of them as a group.

The problem is that doing this breaks the dragging of the shapes on the screen, and the first one of the children shapes doesn't follow the dragging of the others. The other children drag along just fine. Am I doing something wrong?

Thanks a lot,

Pierre

private void onPropertyChanged(object sender, PropertyChangedEventArgs args){

if (args.PropertyName.Equals(nameof(this.IsSelected)))

{

foreach (var child in this.ChildrenViewModels)

{

child.IsSelected = this.IsSelected;

}

RadGridView Opening Groups Programmatically

Hello,

I have a requirement where I need to open the Groups defined in a RadGridView programmatically. Basically the apporach I am looking for is to iterate over all the groups though an accessor function in RadGridView. However, there does not seem to be any accessor function to get the Groups.

It is important that I get the reference to the all the GridViewGroupRow object so that I can decide which ones to open/close. If there a way to do this from the RadGridView object and what functions / properties need to be used ? If not what are the alternatives ?

Thanks,
Chait

Why is CartesianChartGrid not displayed on computer with Windows 7 (with servicepack 1)?

Hello. I developed WPF MVVM Prism 6 application. There is RadCartesianChart with CartesianChartGrid there. Please see XAML below:

<telerik:RadTileView Grid.Row="1" Grid.Column="0" PreservePositionWhenMaximized="True" MinimizedColumnWidth="150">

<telerik:RadTileViewItem Header="First signal chart">

<telerik:RadCartesianChart x:Name="chart1" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" EmptyContent="{Binding FirstSensorChartEmptyContent}">

<telerik:RadCartesianChart.Resources>

<Style TargetType="telerik:PanZoomBar">

<Setter Property="Visibility" Value="Collapsed"/>

</Style>

</telerik:RadCartesianChart.Resources>

<telerik:RadCartesianChart.HorizontalAxis>

<telerik:CategoricalAxis LabelInterval="4"/>

</telerik:RadCartesianChart.HorizontalAxis>

<telerik:RadCartesianChart.VerticalAxis>

<telerik:LinearAxis Minimum="-128" Maximum="127" MajorStep="8" />

</telerik:RadCartesianChart.VerticalAxis>

<telerik:SplineSeries CategoryBinding="Item1" ValueBinding="Item2" ItemsSource="{Binding FirstSensorData}" Style="{StaticResource SplineSeriesStyle}"/>

<telerik:RadCartesianChart.Grid>

<telerik:CartesianChartGrid MajorLinesVisibility="XY" StripLinesVisibility="XY" IsTabStop="False">

<telerik:CartesianChartGrid.YStripeBrushes>

<SolidColorBrush Color="#FFD7D7D7" Opacity="0.3" />

<SolidColorBrush Color="Transparent" />

</telerik:CartesianChartGrid.YStripeBrushes>

<telerik:CartesianChartGrid.XStripeBrushes>

<SolidColorBrush Color="#FFD7D7D7" Opacity="0.3" />

<SolidColorBrush Color="Transparent" />

</telerik:CartesianChartGrid.XStripeBrushes>

</telerik:CartesianChartGrid>

</telerik:RadCartesianChart.Grid>

<telerik:RadCartesianChart.Behaviors>

<telerik:ChartPanAndZoomBehavior DragMode="Pan" ZoomMode="Both" PanMode="Both"/>

</telerik:RadCartesianChart.Behaviors>

</telerik:RadCartesianChart>

</telerik:RadTileViewItem>

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

</telerik:RadTileView>

As you can see in my application I use RadCartesianChart inside RadTileView. I display the layout of only one chart, but all eight of them. Each of them is in its own RadTileViewItem. The problem is that the one of my customers doesn't see layout grid on his computer. He sees: 1) X-axis and Y-axis, 2) All the risks and labels of individual segments on the X-axis and Y-axis, 3) The series (signal curve) but he doesn't see layout grid! He has Windows 7 OS with servicepack 1 on his computer. But the other customer who also install my application sees layout grid perfectly. This second customer also has a computer with Windows 7 OS with servicepack 1 but he has no problem with visualizing of charts.
