Load data asynchronously using an XMLDataProvider

Hello,

How can I load the data asynchronously using an XMLDataProvider. Following is the code I tried. I have set IsAsynchronous to true. But financialInfoProvider.Data is returning Nothing in the below code snippet.

Dim financialInfoProvider As New XmlDataProvider()

Dim finacialInfoXMLPath As String = String.Empty

finacialInfoXMLPath = BuildFinancialInfoXML()

financialInfoProvider.IsAsynchronous = True

financialInfoProvider.Source = New Uri(finacialInfoXMLPath, UriKind.RelativeOrAbsolute)

financialInfoProvider.XPath = "/RemainingFinancialInfo/Property"

m_GridDataSource = New ObservableCollection(Of XmlNode)(DirectCast(financialInfoProvider.Data, IEnumerable(Of XmlNode)))

Thanks and Regards,
Norbert John

Does anyone know if there is a ValidationSummary control similiar to Silverlight for WPF?

I have done alot of work with RIA and Silverlight, and am now on a WPF project. Trying to get my arms around Validation.

Anyone have any good articles on a solid approach to Validation?

Get focus to the user control in RadPanelBar

In the RadPanelBar, I added a user control that has a few text boxes. When I select the RadPanelBarItem, I’m unable to get the focus on the first textbox in the user control. I have the FocusManger.FocusedElement bound to the first text box in the user control. How can I get the focus to the first textbox in the user control? Please advise.

Thanks

Default selected month/year when DateSelectionMode==Month

I'm using the RadCalendar in Month selection mode (DateSelectionMode="Month"). I want the control to default to the current month and for this month to be visibly selected by default as well.

When I default the SelectedDate and/or DisplayDate properties to the current date the current month is still not visibly selected.

The only way I can get this to work is via a hack like:

Loaded += (s, e) =>

{

var today = DateTime.Today;

calendar.SelectedDate = new DateTime(today.Year, today.Month, 2);

calendar.SelectedDate = new DateTime(today.Year, today.Month, 1);

};

Is this a bug? Is there a better way to default to the current month?

[Solved] Binding columns with data from orm list

Hi everyone, I'm newbie when it comes to WPF so i have some - maybe too basic question, but still.
I have a question on how to populate specific columns in radgrid view with columns in List that i got from my orm model.

For example - this is my code behind to set datacontext of a grid view P.S. I would like to put that into resources:

public partial class MyClass : Page

{

public List<MyTable> myList { get; set; }

public Drzava()

{

using (MyModel dbContext = new MyModel())

{

myList = dbContext.MyTable.ToList();

}

InitializeComponent();

myGridView.DataContext = myList;

}

if I set ItemsSource="{Binding ElementName=myPage,Path=myList}" , i get populated all the columns, but i only want specific ones...so i tried somethink like that:

<telerik:RadGridView Name="myGridView" Margin="12,65,12,12" ItemsSource="{Binding ElementName=myPage,Path=myList}" AutoGenerateColumns="False">

<telerik:RadGridView.Columns>

<telerik:GridViewColumn DataContext="{Binding Path=Id}"></telerik:GridViewColumn>

</telerik:RadGridView.Columns>

</telerik:RadGridView

But I cannot get it to work...
Thank you in advance for the reply and help.

-->File List (observablecollection too)

I need to have in the same tree files and folder.

I've no problem creating a treee browsing Folders:

<Grid>

<Grid.RowDefinitions>

<RowDefinition Height="*"/>

</Grid.RowDefinitions>

<Grid.Resources>

<HierarchicalDataTemplate x:Key="NodeTemplate" ItemsSource="{Binding SubFolders}">

<TextBlock Text="{Binding Name}"/>

</HierarchicalDataTemplate>

</Grid.Resources>

<telerik:RadTreeView Name="uxRadTreeView" ItemsSource="{Binding RootFolder.SubFolders}" ItemTemplate="{StaticResource NodeTemplate}" AllowDrop="False" IsDragDropEnabled="True" DragEnded="uxRadTreeView_DragEnded" />

</Grid>

But how can I get files with that too?

They both have a "Name" property
