WPF demo not running under Chrome

I have a Dell laptop running Windows 7 and Chrome 12.0 (most current version). Here's what happens when I try to run the WPF demo:

1) I click "Click to Open" on the demo webpage
2) The XBAP downloads to my Downloads folder.
3) Chrome displays "This type of file can harm your computer. Are you sure you want to download Telerik...amples.xbap?" on the downloads bar at the bottom of the Chrome window, with "Save" and "Discard" buttons.
4) I click "Save".
5) Return to step 2.

I stopped after I had 6 copies of the XBAP.

The demo runs on IE9 on the same laptop. I would love to run the demo on Chrome, which appears to significantly faster on my laptop.

BeginInsert does not seem to be working

I am setting the itemsource of my radgridview using the code
WireInstructionDGV.ItemsSource = obj.GetWireInstruction("BNYBD", "MST", "CPTY", "USD")

To add a new row, i have a button who's click event has
Me.WireInstructionDGV.BeginInsert()

Clicking on the button does not add a new row in the datagrid. any ideas ?

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?

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
