Grid, DataForm, Data Filter in code not xaml

Anyone know of C# code examples that show a RadDataFilter, RadGridView, and RadDataForm all using the same "Source"?
Something like this?

IEnumerable<MyClass> SomeResults;

SomeResults = GetResults();

MyDataForm.ItemsSource = SomeResults
MyDataFilter.Source = SomeResults;
MyGridView.ItemsSource = SomeResults;

I know in xaml you can do something like this for the grid
{Binding FilteredSource, ElementName=MyDataFilter}

but I have no idea how to pull this off in C# code.

When I scroll my grid, the Dataform does not move. When I select next in my dataform, the Grid selection does not move, and when I apply a filter, nothing gets filtered.

This setup (Filter, Grid, dataform) will be used to display items from multiple sources, therefore I have to do it all in code.

Thanks for any help.

bound XamlProvider not updated when adding Paragraph in code behind

Hi

for storing RadDocument content in DB we use the Xaml format and get the Xaml
using the XamlDataProvider, binding its Xaml dependendency property
to a property of some custom class.

This works very well and reliably in virtually all situations and with
all kinds if RTF content.

Now I have a situation where I append a new paragraph to the richtextbox's
Document using

currentParagraph.Parent.Children.AddAfter(currentParagraph, newPargraph);

In this case both XamlDataProvider.Xaml doesn't change und doesn't update my bound
property and also the richtextbox's document isn't updated visually: the new paragraph is not displayed.
However when i check the xaml of richtextbox.Document using

xaml = new XamlFormatProvider().Export(richtextbox.Document);

the new Paragraph is there.

So there seems to be a discrepancy between the
"logical" content of the document and the one actually rendered.

How can that be?
Is my way of appending the paragraph not the recommend one?
Do i need some extra code for updating the document (kind of refresh or so?)?

Thanks
Chris

DragandDrop between 2 ListBoxes

Hi!
I have a question/problem with DragAndDrop and listBoxes.
I have two collections:
   var coll1 = new ObservableCollection<User>() {new User() {Id = 1}, new User() {Id = 2}};
var coll2 = new ObservableCollection<User>() { new User() { Id = 2 }, new User() { Id = 4 } };
listbox1.ItemSource=coll1;
listbox2.ItemSource=coll2;

I can copy some items from listbox1 to listbox2 via draganddrop, but when i want to drag from listbox1 to listbox2 item User(id=2) I put listbox2.AllowDrop= false, because i don't want that listbox2 contains two equal items User(id=2)

So it works, but i want more ;) I want to show why it is impossible to drop item to listbox.

        private void OnDragInitialize(object sender, DragInitializeEventArgs e)
        {
            e.AllowedEffects = DragDropEffects.Copy;
            var data = ((FrameworkElement)e.OriginalSource).DataContext;
            e.DragVisual = new DragVisual()
            {
                Content = data,
                ContentTemplate = this.Resources["DragTemplate"] as DataTemplate
            };
            DataObject dataObject = new DataObject();
            dataObject.SetText(data.ToString());
            dataObject.SetData("DragData", data);
            dataObject.SetData("Text", data.ToString());
            e.Data = data;
        }

I want to show something like this link

Thanks in advance!

RadGridView in not selected RadTabItem has 0 items

Hello,

I have a problem with RadGridView inside RadTabItem - same as in this your example (WpfApplication3.zip). RadGridView on 3rd RadTabItem has no items before you select it.

Try to change your code:

public MainWindow()

{

InitializeComponent();

this.radGridView1.ItemsSource = GenerateProducts();

this.radGridView2.ItemsSource = GenerateProducts();

MessageBox.Show(radGridView1.Items.Count.ToString());

MessageBox.Show(radGridView2.Items.Count.ToString());

}

There are 19 items in radGridView1 in 1st RadTabItem, but radGridView2 in 3rd RadTabItem has 0 items. In my project I have same problem with version 2011.3.1220.35 and 2012.1.0326.35 too. With previous version used in my project (2010.3.1110.35) it works fine.

Can you help me, please?

Thanks,
Maros

MenuItem and updating IsChecked

Hello,
I'm using RadMenu in an MVVM Caliburn Micro application,I've also a RadDocking that contains my views ... some views are sistem views and they should be enabled/disabled by a menu called Views...I've got difficulties since if I just use the menu (check/unchek) for showing/hiding it work fine, but if I start closing from the "X" I got the IsChecked desinked with the real view state.... since I use this this piece of code for the RadMenu, where do I specify the SubmenuOpened event? If I'm able to access it I can calculate the state of the views...

<UserControl.Resources>

<BooleanToVisibilityConverter x:Key="booleanConverter" />

<selectors:MenuItemTemplateSelector x:Key="templateSelector"></selectors:MenuItemTemplateSelector>

<HierarchicalDataTemplate x:Key="MenuItemTemplate" ItemsSource="{Binding Items}">

<TextBlock Text="{Binding Text}" cal:Action.TargetWithoutContext="{Binding}"

Visibility="{Binding IsVisible,Mode=TwoWay,Converter={StaticResource booleanConverter}}" />

</HierarchicalDataTemplate>

</UserControl.Resources>

<Grid>

<telerik:RadMenu x:Name="MenuList" ClickToOpen="False" BorderBrush="Transparent" ItemsSource="{Binding Items}" ItemTemplate="{StaticResource MenuItemTemplate}"

cal:Message.Attach="[Event ItemClick] = [Action OpenView($eventArgs)]" >

<telerik:RadMenu.ItemContainerStyle>

<Style TargetType="telerik:RadMenuItem">

<Setter Property="IsSeparator" Value="{Binding IsSeparator}" />

<Setter Property="IsChecked" Value="{Binding IsChecked, Mode=TwoWay}" />

<Setter Property="IsCheckable" Value="{Binding IsCheckable}" />

<Setter Property="StaysOpenOnClick" Value="{Binding IsCheckable}" />

</Style>

</telerik:RadMenu.ItemContainerStyle>

</telerik:RadMenu>

</Grid>

</UserControl>

Thanks
