Try putting Text="{Binding Path=TeamDriver1, Mode=Default, UpdateSourceTrigger="LostFocus"}" to check that the update is getting triggered.

Hello Pete,

The update is getting triggered .. My one more question is suppose I include 2 instance of the same view in my main page, If i update the data in 1 view then the data should be updated in the second view automatically rite ?? Correct me if I am worng .. Because this is not happening when I tried this scenario.

EG: I include my views in main window like this,

<StackPanel>
<customView:F1TeamView/>
<customView:F1TeamView/>
</StackPanel>

Regards,
Smile | :)

It will only update if both views point to the same instance of data.

It is the same instance of the data .. I initialize the list in the constructor of the view model and return the same list to both the views .. and one more thing . If I make changes to the data in ui and display the members in messagebox .. it will still show me the old values ..

WPF: Vista style window

How can we have vista style window (i.e. with drop-shadow and rounded corner) in Windows XP?

If I add 'PresentationFramework.Aero', it changes look for controls and not for main window.

I've set WindowStyle>None, Background>null and AllowTransparency>True for the window. And then, added a rectangle with rounded corner and drop-shadow. It emulates style perfectly but causing serious performance threat.

Can you people suggest me better approach?

Nope

Face it, any time you are bypassing the native rendering engine the OS uses you are going to take a performance hit. I don't care what anyone says.

This is why Vista and 7 are 'NEW'. They were written with the intent to support this new look and feel so the OS internals, all the way down to the rendering engines, were optimised towards that purpose intentionally.

On older OSes if you turn off native rendering and do all your own window drawing in your code you are always going to incur a performance hit because you are essentially moving that code up a layer, or at very least adding cycles in the way to signal an alternate rendering routine.

Retrieving template parts [I FEEL FRENCH]

I have a page defined in xaml, and I'm using a 3rd-party control. I've created a style that overrides the control's template, and I've added a couple of new "parts" to the template.

In the C# code, when I call control.FindName("MyNewPart"), it returns null. I tried calling control.ApplyTemplate()before calling FindName, but it returns false.

How do I get that part from the control?

I GAVE UP ==============================

Yeah, I spent a couple days on this problem and with nothing to show for it that could be even remotely viewed as "progress".

Nope - won't work because a ControlTemplate object does not expose a FindName method in Silverlight.

Hi Shubhabrata,

There's exist no such tool to convert ASP.NET application to a Silverlight application. ASP.NET applications & Silverlight applications are two different things and there is no relation between them. One is in .aspx and the other is in .xaml. The controls are all different for them. Thus, you can't use any tool to convert from one to another.

If you want to migrate from one to the other, you have to know each technology first and then you have to manually convert them. Once migrated to Silverlight, you will get more power over your application with the help of Rich UI and StoryBoards.

What are you doing to bind your collection to your datagrid at runtime?

Can't display "Wingding 3" font [modified]

fjparisIII18-May-10 9:27

I need to display several characters from the Wingdings 3 font family. That's the name of the font family, not the name of the True Type font family file. What I did was copy the wingdng3.ttf file to my project root and made sure that its BuildAction was set to Resource. Then in my XAML I use this syntax to display a single character at the beginning of a TextBlock:

<TextBlock
    Name="section1Title"
    >
    <Run FontFamily="WingDng3.ttf#Wingdings 3"></Run> Help on the tutorials
</TextBlock>

When displayed in my application, the wingding character appears as a square, just as in the above markup, but you'd expect that in the markup. But appearing as a square in the running Silverlight application indicates that the font family I chose for it was not located. What am I doing wrong?

Edit: Upon further investigation I discovered that my "expectation" about the display of the markup was wrong. If the font can be displayed, it is displayed properly in the markup, at least in VS2010. Nevertheless, I still don't know how to get VS2010 to display an embedded font.

I have a problem with that extra cell in the grid. I have been unsuccessful to remove it. Perhaps someone can see what the issue is?

If your datagrid width is fixed, then you will continue to get that cell.
It could also be because your Grid row width is hard coded.

Trying setting the width to auto.

*Edit*
Er...yes I mean grid column width and not the row height - apologies.
