If you just need to use the host because you have a none WPF chart, why not take a look at this[^]?

A native chart is of course the best solution. However, we have a lot of expertise with this third party chart control (ChartFx) that it would be too costly in terms of time to abandon it now. We have several WinForms products and we have layered on many custom interactive chart features. We're starting a new product and want to use WPF for all but the chart.
ChartFx is developing a WPF native chart, but it may not have the same feature set nor does it's release schedule match ours.
Anyway, I did find the "PropertyMap" property of the WinFormsHost, but it only maps to properties of the winForms host class. Is there some way to add a new property? For example, I would map a new property named "DataSeries" to a method in the xaml.cs code. Then I would bind the "DataSeries" property to my ViewModel. Any tips on doing this?
Thanks,
Mitch

I think I answered my own question. Since the ViewModel implemented INotifyChangedProperty I just added an event handler in the view's code behind to listen for each event from the viewModel. When it's the even I want, I update the winforms chart.
This pseudo binding still relies on both the View and ViewModel to agree on a property name. But that's the nature of binding anyway.

Congratulations. It's just a shame you've had to use the Interop Helpers; they are such a bind. Pun unintended.

That was actually what I meant. I should have put in more details.

Hello!
I have such task - to create control that union two controls (DataGrid from WPFToolkit and standard Toolbar). On a large scale, it doesn't matter what particular controls it unions, I need to find out the common practices that can be used to build what I need. At first glance, I need something like user control, i.e composition of controls, that I can implement as a whole and reuse then. But, my task requires me to have possibility to tune my composite control in XAML. So, if I compose Toolbar and DataGrid, I want properties and events of both them would be exposed. So I could set in XAML both, for example, columns of datagrid and bars of toolbar:
(I put spaces in tag names intentionally, because loacal parser didn't type them for some reason)
< MyDataGridToolBarControl ><br />
< DataGrid ><br />
< DataGrid.Columns ><br />
< DataGridTextColumn Header="firstColumn" ><br />
< /DataGridTextColumn ><br />
< DataGridTextColumn Header="secondColumn" /><br />
< /DataGrid.Columns ><br />
< /DataGrid ><br />
< ToolBar Background="{x:Null}" > <br />
<button tooltip="New"><br />
<image source="New.png" /><br />
</button><br />
<button tooltip="Save"><br />
<image source="Save.png" /><br />
</button><br />
<button tooltip="Delete"><br />
<image source="Delete.png" /><br />
</button> <br />
< /ToolBar ><br />
< /MyDataGridToolBarControl >
The only decison that suits me less or mor for now is to make custom control inherited from Datarid (as DataGrid is more significant in this pair) and redefine Template including both datagrid and toolbar. This gives me all power of datagrid but, if I want get Toolbar part, I need to do it through code, seeking it in viual and logical trees i.e. getting access o it programmatcally, which is not pretty decision.
Please help a newbie to solve this task ) Thanks in advance...

You're obviously very new to this. Any property you add to your control, can be set from XAML.

Thats it, I'd like not to transmit every property and event of each component control to the level of composite control. I'd like (if it is posible) to inherit all of them! But multiple inheritance in c# is not allowed, so I can't go this way! So, because of it I am here and your answer is inappropriate. If you are lazy to answer, it would be better not answer at all. Thanks

Hi.
I'm working VS2008 SP1 and SilverLight 2.
My SL's Application has worked until 2 hours ago very well ,but Browsers just couldn't show it anymore.
BTW I change my project name manually 
What's wrong with it ?
How can I fix it ?
Would appreciate for any guides.

If you changed the name of something, make sure the name is changed anywhere
in the code that's effected.
For example, if the name of the xap is now different, you may need to change
the reference to the xap in your hosting web page.

Hello.
Is it possible to assign a command parameter to a canvas? Instead of using buttons we wish to use canvases for certain parts of the UI, but it needs to send a command parameter like a button. Can we do this?
Regards, E.

You mean command bindings ? See here Link[^]
|
|
|
|
|
Hello, exactly right 
One issue though is lack of backspace or enter key support. Can we trigger these commands via a canvas press?
|
|
|
|
|
I might not be understanding your question correct. But wouldn't KeyBinding work ?

You want to look in to silverlight, that's how you do WPF for the web.

Has anybody used these and got them to work?
I just get: The attachable property 'VisualStateGroups' was not found in type 'VisualStateManager'.

I did and came to the conclusion that I will get round to using themes when they are ready for non trivial apps.
Thanks.

I Have a requirement where i need to pass only sql select statement as a parameter to Service. Instead of writing query in the service i need to accept the query as a parameter.
Any suggestions, samples or links would be appreciated.
Thanks

You can't pass it as a string?

Well an string would work but... that could be quite dangerous, it's quite easy to make injection attacks with that technique.
I would limit that free querying to the final user.

From the MSDN link,
"Used within the template of an item control to specify the place in the control’s visual tree where the ItemsPanel defined by the ItemsControl is to be added."
(stress on the underlined words)
One way to look at it is, it gives you a starting point to start looking out for your Items in the Visual tree. You know, they surely will be in the ItemsPresenter (i.e. if you follow the use of ItemsPresenter in your ControlTemplates)
