SO far it seems to be working well. Overall it's very little code, but the number of message classes is growing. I think that's where the confusion might come in. I could make one generic message class.
As far as knowing who sent a message, the call stack shows that. But I understand what you're saying.

Can you describe in one paragraph how you constructed your dynamic tab control. I have a similar requirement (max 5 tabs). If so please email me direct (your email is disabled on the messages).

I'm not sure what you mean by "constructed your dynamic tab control.

I was under the impression your tabcontrol populated the tabs and content based on data rather than at design time. I have a number of ideas how to achieve this but I am trying to reduce the experimentation time required to get it working and was hoping you had already researched this and had some guidance or links to examples you had used.

Ok, I see
My tab control is bound to a class, so in the XAML I have
<TabControl Grid.Row="2"
Grid.Column="2"
x:Name="MyTabControl"
BorderBrush="#6593CF"
Background="White"
ItemsSource="{Binding TabManager.Tabs}"
SelectedItem="{Binding TabManager.ActiveTab}"
Margin="2"/>
My Tab Manager class is this
public class ViewManager : BindableBase, ITabManager
{
#region Events
public event EventHandler TabActivated;
#endregion
#region Bound Properties
private ObservableCollection<TabItem> _Tabs = new ObservableCollection<TabItem>();
public ObservableCollection<TabItem> Tabs
{
get { return _Tabs; }
set
{
if (_Tabs != value)
{
_Tabs = value;
RaisePropertyChanged("Tabs");
}
}
}
private TabItem _ActiveTab;
public TabItem ActiveTab
{

{
if (_ActiveTab != value)
{
_ActiveTab = value;
RaisePropertyChanged("ActiveTab");
if (TabActivated != null)
{

}
return retVal;
}
public void RefreshTabInfo(AppMessageArgs Args)

foreach (var tab in Tabs)

_DataEntryViewModelBase vm = view.DataContext as _DataEntryViewModelBase;
ViewInfo vi = (ViewInfo)tab.Tag;

_DataEntryViewModelBase vm = (_DataEntryViewModelBase)view.DataContext;
retVal = vm.PromptSaveChanges(true);
if (!retVal)
{
break;
}
}
return retVal;
}
#endregion
}
Then when I want to add a tab from a VM I do this:
private void loadView(BOMArgs Args)
{
ViewInfo tabInfo = new ViewInfo
{
View = View.BOM,
EntityId = Args.BOM.Id
};
if (tabInfo.EntityId > 0 && TabManager.IsTabOpen(tabInfo))
{
TabManager.ActivateTab(tabInfo);
}
else
{
BOMViewModel vm = new BOMViewModel(Engine);
vm.Load(Args);
UserControl view = new BOMView();
view.DataContext = vm;
TabItem tabItem = new TabItem
{
Header = vm.GetEntityCaption(),
Content = view,
Tag = tabInfo
};
TabManager.AddTab(tabItem, true);
}
}
Works perfect, although I need to de-couple the view => vm dependency in the 'else' section.

Ok, what am I doing wrong here???
I have a Client Entity:
public class ClientEntity : _EntityBase
{
private string _ClientName = string.Empty;
public string ClientName
{
get { return _ClientName; }
set
{
if (_ClientName != value)
{
_ClientName = value;
RaisePropertyChanged("ClientName");
IsDirty = true;
}
}
}
private PayTypeEntity _PayType;
public PayTypeEntity PayType
{
get { return _PayType; }
set
{
if (_PayType != value)
{
_PayType = value;
RaisePropertyChanged("PayType");
IsDirty = true;
}
}
}
}
In my XAML, I am binding the PayTypes combo like this:
<ComboBox Grid.Row="1"
Grid.Column="3"
ItemsSource="{Binding PayTypes}"
SelectedValue="{Binding Client.PayType.Id, Mode=TwoWay}"
SelectedValuePath="Id"
DisplayMemberPath="Caption"/>
When I select a PayType it does not get set on the ClientEntity.
If it's not broken, fix it until it is

You're not binding to the PayType property on the ClientEntity class; you're binding to the Id property on the PayTypeEntityClass instance returned from the PayType property on the ClientEntity class.
Try this:
<ComboBox
Grid.Row="1" Grid.Column="3"
ItemsSource="{Binding PayTypes}"
SelectedValue="{Binding Client.PayType}"
DisplayMemberPath="Caption"
/>

Ok, so I'm still stuck here. I thought this was working, but it's not quite right. It saved the Id ok, but when I reopen it, it doesn't set the value back to what I selected. Here's what I have:
<ComboBox Grid.Row="1"
Grid.Column="3"
IsEnabled="{Binding Path=FieldEnableHelper.PayType}"
ItemsSource="{Binding PayTypes}"
SelectedValue="{Binding Client.PayType}"
DisplayMemberPath="Caption"
TabIndex="10"
Style="{StaticResource ComboBoxStyle}"
Width="150"/>

I want to make a Choose from list in my silverlight application. like click one button it will show a list of suggestion from that you can choose.
|
|
|
|
|
Its called a combo box and it binds to a collection of objects (your class of suggestions) and a selected object, the suggestion the user has selected
Add a button on the view that populates the ObservableCollection<suggestionobject> in the Viewmodel/code behind.

Sorry but Combo box shows only one dimensional data but I have to show multiple column from that they can choose.
|

Actually a combobox can take a DataTemplate and display multiple columns.
You use a ListBox or a DataGrid, it really depends on your requirements.

Hello
I am using DrawingContext to draw text, and then i print visual throu PrintDialog. I want to convert input from milimeters. I do not know formula and on google i only found a few pieces, but i realy want to be printer independet.
I found on a Some page
1 mm = 3.779528 px
Is this printer independet. I am writing an application that will print on normal A4 printer or on 60mm x Reciept type printers. My app is already printing, but some values i want to be in pixel and some in mm.
Thank you
Edit: Upon remote testing i noticed that no matter if Printer is 600DPI or 300dpi. I can simply ignore these values

WPF uses Device Independent Pixels, you may have a hard-time with this asumption
Beauty cannot be defined by abscissas and ordinates; neither are circles and ellipses created by their geometrical formulas.

I Know WPF is DPI indipented when putting it on screen.
Does that extend to Printing? I am using Drawing Context and all values are pixel based. My Printer has resolution 600dpi. But other printer that is currently not awaible is STAR SP 200 Series. It is a 300DPI Matrix type printer.

Hi,
Can somebody highlight the uses please. Also, there are lot of unused usings being created in this files, is there anyway we can suppress them?
