Hi All,
'IEditableCollectionView' is A good concept to deals with data adding and removing new items, as well as editing items in a transactional way to bind WPF Data Grid.
Can you help me..How to implement it for WPF Data Grid ?
My Requirement : I have multiple WPF Data Grid's with single data source ( DataSet Or DataTable). I want add new empty row to all datagrid's at single click (i did it partially).
** All Datagrid columns are single click editable -- done.
But whenever user click on 'add' button an empty row is added to all three grid's (above said). i want to update data on button save click event.
My problem is.... i am unable to get User entered data from CollectionView...
if any body have good knowledge on 'IEditableCollectionView' concept...please explain me How to edit/Update and Delete rows from collection view...
if you provide samples or Url's really gr8 helpful me..
Thanks in advance.

Hi,
My project contains a class, Symbol, which derives from UserControl and adds some custom dps etc... In code, Symbol also implements a Popup containing a TabControl along with the relevant click handlers to make this popup appear. Any objects which derive from Symbol have this popup which works fine.
I now need to be able to add new custom TabItems to the TabControl in the derived classes. I can do this in my code behind file but was wondering what the correct syntax is in WPF to add a TabItem to a parent's TabControl.
Can anyone help?
Cheers
Rich

Maybe
myTabControl.Items.Add(newTabItem);

Ah sorry, thanks for your response, but I wasn't clear in my OP.
I actually meant what would be the syntax for doing this in XAML? My XAML class derives from a class with the TabControl defined, how can I access it to add a new TabItem within my derived XAML or is this not possible?
TIA
Rich

Maybe the ContentPropertyAttribute[^] is what you need.
There's an example using a List property here[^].
I think you could define a collection dependency property (or property
that implements change notifications) and use that as your control's
[ContentProperty]. That will allow you to specify multiple items in XAML.
Bind the ItemsSource of the embedded TabControl to that property.

There were some add-ins for WCF, WF and WPF development (I don't think they're accessible anymore). For WCF, you didn't really need to use the add-in though. Just having .NET 3.0 installed was enough.

Hi,
I'm in the process of refactoring some code I've inherited and as a part of this I need to re-create a binding which was previously in my WPF in code. The WPF snippet is:
<pre><TabItem Header="Notes">
<my:HelpEditor PlantId="{Binding Path=Id, RelativeSource={RelativeSource FindAncestor, AncestorLevel=1, AncestorType={x:Type my:Symbol}}}">
</TabItem></pre>
But I am now producing these TabItems in code so need to reproduce this binding in my code-behind file. In this case HelpEditor is a custom UserControl with a PlantId dependency property and Symbol is a custom object with a Id dependency property. HelpEditor needs to be bound to the Id in Symbol and so this WPF binding code works fine.
Here is the code I am trying to use in my code-behind file:
<pre>TabItem ti = new TabItem();
ti.Header = "Notes";
helpEditor = new ScadaAlarmViewer.HelpEditor();
Binding idBinding = new Binding("Id");
idBinding.RelativeSource = new RelativeSource(RelativeSourceMode.FindAncestor, typeof(MyStuff.Symbol), 1);
helpEditor.SetBinding(MyStuff.HelpEditor.PlantIdProperty, idBinding);
ti.Content = helpEditor;</pre>
But this doesn't work, I get:
<pre>System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='MyStuff.Symbol', AncestorLevel='1''. BindingExpression:Path=Id; DataItem=null; target element is 'HelpEditor' (Name=''); target property is 'PlantId' (type 'String')</pre>
In the output window. If it's relevant, these TabItems are contained withint a Popup.
Can anyone help?

I think the problem comes from the fact that you are setting the binding before you have put the helpEditor into the visual tree. I think you will need to rearrange into something like:
TabControl tc = ;
TabItem ti = new TabItem();
ti.Header = "Notes";
helpEditor = new ScadaAlarmViewer.HelpEditor();
Binding idBinding = new Binding("Id");
idBinding.RelativeSource = new RelativeSource(RelativeSourceMode.FindAncestor, typeof(MyStuff.Symbol), 1);
ti.Content = helpEditor;
tc.Items.Add(ti);
helpEditor.SetBinding(MyStuff.HelpEditor.PlantIdProperty, idBinding);

I think you're really confused. If your application contains the xls, how is it something that needs downloading ? It's already on the user machine. What do you mean exactly ?

Hi.
Can we run SL Applications on Linux Servers ?
Thanks

Silverlight applications run on the client so it doesn't matter
what server you use, as long as the server can serve up .XAP files
and any other resources the Silverlight app may need.

There are many articles here on CodeProject that explain how to use all the features of WPF, from basic to advanced.

Why would you 1 vote someone for stating the obvious ? It's not his fault that you're stupid.

I didn't vote it 1, you can open your eyes and see my vote right now.
I think you are more stupid than me , because you judge about something that you don't know anything about it.

Also, to get you started, there is sample templates
for Menu and MenuItem in the documentation:

Hey guys,
I'm developing a kind of website content management system. Users can drop 'blocks' of content on a page and some blocks are silverlight applications (for example picturebooks). I want users to be able to 'skin' the silverlight application like a css stylesheet would do that for a webpage. I was thinking of defining properties for objects used in the silverlight application (for example a button and an image) and let the user decide the values of the properties.
Is there a built in feature in Silverlight which allows me to create such functionality or do I have to write code for each and every property in silverlight which means a lot (A LOT) of coding...
Thanks!

You could merged dictionaries to provide alternate "skins" for controls.
Allowing the user to change them will require some coding definitely, because
you'll need to build dictionaries at runtime and probably need a way to save
the user's preferences.
The ImplicitStyleManager can help for applying styles to controls at
runtime so you don't have to do that part manually.
