Binding to Grid with Entity Framework 4.1 Codefirst

Hello all.

I have updated my Entity Framework 4.0 to 4.1Since i have a problem with the binding to Radgridview control.

My Dataclasses as sample:

namespace KfzOrtung6DataClasses.Modells

{

public class Fahrzeuge

{

public Fahrzeuge()

{

this.FahrzeugPositionen = new ObservableCollection<Positionen>();

}

[Required]

[Key]

[DatabaseGenerated(DatabaseGeneratedOption.None)]

public Guid ID { get; set; }

[Required]

[MaxLength(50)]

public string Name { get; set; }

[Required]

[MaxLength(50)]

public string Kennzeichen { get; set; }

public string Rufnummer { get; set; }

public int Aktiv { get; set; }

public DateTime Ablaufsimkarte { get; set; }

[MaxLength(4000)]

public string Bemerkung { get; set; }

public virtual ObservableCollection<Positionen> FahrzeugPositionen { get; private set; }

}

In my UC i have into the Loaded-Event:

this.DataContext = this.ItemsSource;

The Collectionview Method:

ICollectionView _itemsSource;

public ICollectionView ItemsSource

{

get

{

if (_itemsSource == null)

{

using (var ktt = new KfzContext6())

{

ktt.MFahrzeuge.Load();

var c = ktt.MFahrzeuge.Local.ToBindingList();

var collectionViewSource = new CollectionViewSource {Source = c};

_itemsSource = collectionViewSource.View;

}

return _itemsSource;

}

set

{

_itemsSource = value;

OnPropertyChanged("ItemsSource");

}

#endregion

In my context class:

namespace KfzOrtung6DataClasses.Modells

{

public class KfzContext6 : DbContext

{

public KfzContext6(): base("KfzContext6")

{

}

public DbSet<Fahrzeuge> MFahrzeuge { get; set; }

public DbSet<Positionen> MPositionen { get; set; }

public DbSet<Tarife> MTarife { get; set; }

public DbSet<Benutzer> MBenutzer { get; set; }

public DbSet<SmsProtokoll> MSmsProtokoll { get; set; }

protected override void OnModelCreating(DbModelBuilder modelBuilder)

{

base.OnModelCreating(modelBuilder);

// Hier können manuelle Änderungen an Datenbank vorgenommen werden!!

//Beispiel:

//modelBuilder.Entity<Benutzer>().Property(r => r.ID).HasColumnName("Id");

}

My save method:

selectedFahrzeugAusListe.Aktiv = chkFahrzeugAktiv.IsChecked == true ? 1 : 0;

selectedFahrzeugAusListe.Rufnummer = txFahrzeugGpsnummer.Text.Trim();

selectedFahrzeugAusListe.Kennzeichen = txFahrzeugKennzeichen.Text.Trim();

selectedFahrzeugAusListe.Bemerkung = txFahrzeugKommentar.Text.Trim();

selectedFahrzeugAusListe.Name = txFahrzeugName.Text.Trim();

selectedFahrzeugAusListe.Ablaufsimkarte = dateTimePicker.DisplayDate;

using (var ktt = new KfzContext6())

{

ktt.MFahrzeuge.Add(selectedFahrzeugAusListe);

ktt.SaveChanges();

ItemsSource.Refresh();

}

In xaml of the radgridview:

<telerik:RadGridView AutoGenerateColumns="False"

CanUserFreezeColumns="False"

CanUserResizeColumns="True"

Margin="10,6,10,13"

x:Name="FahrzeugGrid"

RowIndicatorVisibility="Visible"

AutoExpandGroups="True"

IsFilteringAllowed="False"

ShowGroupPanel="False"

ShowGroupFooters="False"

IsReadOnly="True"

SelectionChanged="FahrzeugGrid_SelectionChanged"

ActionOnLostFocus="None"

AreRowDetailsFrozen="True"

CanUserInsertRows="False"

CanUserDeleteRows="False"

RowDetailsVisibilityMode="Visible" Grid.Row="1"

ItemsSource="{Binding ItemsSource, ElementName=DataSourceChangeNotificationsFahrzeugControl}"

DataLoaded="FahrzeugGrid_DataLoaded" >

<telerik:RadGridView.ParentRow>

<telerik:GridViewRow IsTabStop="False" />

</telerik:RadGridView.ParentRow>

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}"

Header="Fahrzeugname" Width="200" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding Kennzeichen}"

Header="Kennzeichen" Width="140" />

<telerik:GridViewColumn Header="Aktiv" Width="40" IsFilterable="True">

<telerik:GridViewColumn.CellTemplate>

<DataTemplate>

<CheckBox IsEnabled="False"

IsChecked="{Binding Path=Aktiv, Converter={StaticResource CopnvertIntToBool1} }">

</CheckBox>

</DataTemplate>

</telerik:GridViewColumn.CellTemplate>

</telerik:GridViewColumn>

<telerik:GridViewDataColumn

DataMemberBinding="{Binding Rufnummer}"

Header="GPS Nummer" Width="150" />

<telerik:GridViewDataColumn

DataMemberBinding="{Binding Ablaufsimkarte}"

Header="Ablauf Karte" Width="90" />

<telerik:GridViewDataColumn

DataMemberBinding="{Binding Bemerkung}"

Header="Kommentar" Width="*" />

</telerik:RadGridView.Columns>

</telerik:RadGridView>

It shows all cars, but when i save a new car, the list doesn´t refresh.
When i reload the UC, then all cars (the new one too) are all there.

Can you please help?

RadDocking looping thru the radpanes

Hey

We use telerik:RadDocking - telerik:RadSplitContainer - Radpanes. it is dockedbottom. Mouse over minimized docked panes, looping sometimes (it tries to show the panes in a loop). We don't have lot of coding going on related to raddocking.

Do you have any solution to this or do you have any similar posts?

I am trying figure out a work around.

Thanks

Raddocking and Radgridview export issue

Hey,

I have a Radrgridview under RaDDocking/RadSplitContainer/RadPane.

This radPane is set to AutoHide. If i make the docked pane visible, export works fine.

Export is not working when docked pane is not made visible atleast once,

RadGridview is bound to Observable collection.

Thanks for the Help

Multimonitor Docking breaks after Lock Windows

I am running the latest paid for version of Telerik WPF as downloaded today, on an XP workstation with 2 monitors.

1. Launch "C:\Program Files\Telerik\RadControls for WPF Q2 2010 SP1\Demos\Examples.WPF\Telerik.Windows.Examples.exe"
App opens on Primary monitor (in my case, the one on the left).
2. Hover on Browse Controls circle, choose "Containers"
3. Choose "Docking" icon
4. Choose "Split Containers". Screen rearranges with a docking demo
5. Drag and release "Document 1" out of the main window, but still on the same monitor.
6. Press "Windows Key + L" to lock Windows
7. Type in your username and password to unlock Windows
Notice now that the "Document 1" window is now on Right Monitor.
Main window is still in original position on Left Monitor
8. Try to drag "Document 1" to the Main Window - don't let go of mouse button (i.e. keep dragging)
- as the mouse moves onto Monitor 1, the "Document 1" window is not drawn on Left Monitor, only on Right Monitor
- compass on Main Window does not appear
- moving the mouse back onto Monitor 2 still has the "Document 1" window

Other behaviour:

Dragging the main window onto the right monitor, you can then redock "Document 1" into it.
With the main app on the left monitor, Dragging any of the other panels out of the app onto the right monitor and then (without letting go) back onto the left monitor - the controls do not render on the left screen.

Thanks,
Lee Oades

Stylingdocumentation

Hi,

I have to style our app and for that I need to change some values in the ButtonChromeStyle.
To check my changes I would like to have a documentation of the ButtonChromeStyle. I need to know when which Borders and Triggers are activated, e.g. what has the user to do in the gui to see the styles:
"PressedVisual"
"ActiveVisual"

<MultiTrigger.Conditions>
    <Condition Property="RenderEnabled" Value="True"/>
    <Condition Property="RenderPressed" Value="True"/>
</MultiTrigger.Conditions>

I hope you can understand my problems.

Thanks and regards,
Patrick

Zoom Map to fit all Push Pins

Hello All,

I am placing multiple push pins all over the state based on addresses. The push pins are placed correctly and I can see them, however, I cannot figure out how to zoom the map in to it's highest zoom level but still keep all of the push pins visible.

Has anyone done this yet?

Thanks in advance...
