I'm using MVVM, PRISM with an outlook bar as a Prism region.

I have made a custom command that changes the main region when an OutlookBaritem is mouse down.  (think MS Outlook, when you click on the 'calendar' bar).  When the OutlookBarItems are bars, everything works fine, but when the application first starts, the outlook bars are minimized to buttons.  

What I noticed:
The mouse down event does not fire when the OutlookBarItem is minimized to a button instead of a bar.
Question:
Is this normal behavior?  
If so, this seems like illogical behavior.  A mouse down on a OutlookBarItem should fire regardless of it's display mode.  (I would assume that when minimized, a different template is used, with a button that has a click event instead of a UIElement that has a MouseDown event?)

Thanks,

I am sure I am missing something obvious in the documentation, but I can't seem to find it. Is there anything built into the GridView control so I can determine if the user actaully changed the data after they entered into edit mode? I expected something in the RowEditEnded event to indicate that. I see the OldValues collection, so i know you are keeping track of the original data, but I don't want to have to write code to manually compare the new old data for every field, especially when the grid could be generated dynamically.

Hi,
I'm using MVVM base on the example of DrillDownCHart. My itemToolTipOpening chart is working fine. But the ChartArea_ItemClick doesn't work. ToolTipOpening and ItemClick share the same viewModel and chart Xaml. 

Updates: I found that this actually working, but it's  just hard to capture the chart, it's blinking. And sometimes it went to tipopenning first and that took awhile comeback to itemClick. So my question are
 1) how to separate these two events, meaning click should not go to ToolTipOpenning
2) how to make the itemClick chart staple. Anything could through xaml?

private

 

 

void ChartArea_ItemClick(object sender, ChartItemClickEventArgs e)

{

DataPoint selectedItem = e.DataPoint ;

 

DrillDownChartViewModel dViewModel = new DrillDownChartViewModel();  

 

dViewModel =

 

 

 

this.ViewModel.ActiveDetails.DrillDownChartSeries.FirstOrDefault(d => d.DataItem == e.DataPoint);

 

dViewModel.LoadToolTipSourceTable(selectedItem);

 

 

 

DrillDownChartToolTip toolTipControl = new DrillDownChartToolTip();

 

toolTipControl.DataContext = dViewModel;

toolTipControl.Height = 200;

toolTipControl.Width = 420;

 

}

Hi!

I have just downloaded the RadControls_for_WPF35_2010_3_1018_Dev Beta. In this version the GridViewSortingEventArgs.SortPropertyName is marked as obsolete. My question is what we should use now when we are doing custom sorting?

Best regards

Hi!

I am attempting to get a Carousel control to work for me but I have been running into some problems.

First off, I started by using a RadCarousel control to display some data about a person. I set the template for the control and bound it to a list of Person objects. Everything worked well until I tried to change the Path/Trajectory of the careousel. I discovered that you cannot change it.

So, I switched to the RadCarouselPanel but I have been running into problems with it.
I have a custom UserControl that displays the person's information but when I add these items the RadCarouselPanel does not rotate the items; however, if I put Image controls in the RadCarouselPanel, it will rotate (up to the point where a user control is next in the list).

The user control is just a grid with an image in the first row, followed by the person's first name and last name in the second row. It's extremely simple.

I have read that people have had problems adding buttons to the RadCarouselPanel because they capture the mouse click event...however my user control does not. It's just....a grid with some stuff in it.

This is my Code-Behind for my window:
(VB.NET)


Public Class MainWindowAttempt2

 

    Public Sub New()

        ' This call is required by the designer.

        InitializeComponent()

    End Sub

    Protected Overloads Overrides Sub OnInitialized(ByVal e As EventArgs)

        MyBase.OnInitialized(e)

    End Sub

 

    Private Sub Window_Loaded(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles MyBase.Loaded

        Dim p As New People

        person1.ThePerson = p.People(0)

        person2.ThePerson = p.People(1)

        person3.ThePerson = p.People(2)

        person4.ThePerson = p.People(3)

        person5.ThePerson = p.People(4)

        person6.ThePerson = p.People(5)

        person7.ThePerson = p.People(6)

        person8.ThePerson = p.People(7)

    End Sub

 

End Class

This is what I have in my Window:

Hi!

I need your help. I have a details panel with toolbar that shows detail information from a RadgridView, next is snippet code:

<StackPanel x:Name="pnlToolbar" Height="55" Margin="0,0,3,0" Width="416">
<telerik:RadToolBar x:Name="tlbDetalle" Orientation="Horizontal" OverflowButtonVisibility="Hidden" Height="54" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" BorderBrush="#FFE9F2FF" BorderThickness="1" HorizontalAlignment="Right" Width="413">

</Button>
<Button x:Name="btnInsertar" Tag="btnInsertar" Click="btnToolBar_Click">

</Button>
<Button Tag="btnGrabar" Click="btnToolBar_Click">

</Button>
</telerik:RadToolBar>
</StackPanel>

<Grid x:Name="pnlDetails Height="249" VerticalAlignment="Stretch" HorizontalAlignment="Stretch">
<Label x:Name="lblCodigo" Content="Código" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" Margin="8,8.5,76,8.499"/>
  <telerik:RadMaskedTextBox x:Name="fmtCodigo" IsEnabled="{Binding kernel:App_PageKernel.EsRegistroNuevo}" Style="{DynamicResource Estilo1MaskedTextBox}" Value="{Binding ElementName=grdGridConsulta, Path=SelectedItem.CA001, Mode=TwoWay, UpdateSourceTrigger=Explicit, Converter={StaticResource ValueConverter}}" Validation.ErrorTemplate="{StaticResource PlantillaErrores}" Margin="87,0,0,8.5" HorizontalAlignment="Left" Width="51.92" VerticalAlignment="Bottom" TabIndex="0" Mask="n0" MaskType="Numeric" HorizontalContentAlignment="Right">

<Label x:Name="lblEjecutable" Content="Ejecutable" Margin="21,121,0,0" VerticalAlignment="Top" Width="77" Height="27"/>

...

...

</Grid>

I wanted to show errors validation by using a Errors Template and setting Validation.ErrorTemplate="{StaticResource PlantillaErrores}" in every control, next is the code from Page.Resources:

<ControlTemplate x:Key="PlantillaErrores">
<StackPanel x:Name="PlantillaErrores">
<StackPanel Orientation="Horizontal">
<Image Height="20" Margin="0,0,3,0" Source="/App_LocalResources/Imagenes/Advertencia.png">
<Image.Effect>
<DropShadowEffect BlurRadius="14" Direction="276" ShadowDepth="1" Color="#FFC2BA9E"/>
</Image.Effect>
</Image>
<Border BorderBrush="Red" BorderThickness="1">
<AdornedElementPlaceholder/>
</Border>
</StackPanel>
</StackPanel>
</ControlTemplate>

Everything is working OK, when errors happen, image and red rectangle around control is showed in correct way, but something extrange is happening when I need to hide Details Panel, the way I do this is by using an opacity effect from 1 to 0 through storyboard action, not hidden by Visibility property, problems is that the Image and Red Rectangle continues showing and they don't be hidden, any way both of them get hidden is when I move mouse over any toolbar button - curiously -, so, image and red rectangle disappear. Maybe something about rendering, I guess, so I tried by this.InvalidateVisual(); into my page class but nothing changes, image and red rectangle continues showing. Same way happens in the other way, when I need to make visible details panel by changing opacity from 0 to 1 through storyboard action and previously image and rectangle was hidden by the action of move mouse over any toolbar button, and next details panel get visible, image and red rectangle continues hidden, only action of move mouse over any toolbar button makes image and red rectangle appear again.

thanks for your help!

what is the best method of hiding the HierarchyExpandButton and the column that it adds to the GridView

Hello!
I need in my application the docking feature of the panes - to be able to put them in any position I need in the docking panel, during runtime. But somehow I need to constrain them so there cannot be any floating panel - I mean if the user drags a RadPane but he is not positioning it in any other place, the RadPane will go back to it's initial position.
Setting the CanFloat property on false is just freezing the pane, but I don't want this behavior.

Is this possible?

Thank you!

I have a treeview bound to a collection of objects that implement INotifyPropertyChanged.  The AssociatedOfferings child collection is a collection of the same type of object.  When I change a value of one of the objects from the ViewModel the change is not reflected in the TreeView.  My View is as follows:


Then in the ViewModel if I take one of the objects and set its IsSelected property to True, or the Name to something else, the change is not reflected in the View.
