How do I tell the field label for a DataFormTemplateField what I'm binding to?

06-30-2009 12:25 AM |

If I have the following code:

<Controls:DataFormTemplateField>

<Controls:DataFormTemplateField.EditTemplate>

<DataTemplate>

<StackPanel Orientation="Horizontal">

<TextBlock Text="$"/>

<TextBox Text="{Binding Path=Bond}" Width="75"/>

</StackPanel>

</DataTemplate>

</Controls:DataFormTemplateField>

The data form doesn't automatically pick up the binding and display the field label and bold it appropriately, presumably because it doesn't know that I'm binding to the bond property.  How can I tell it this so that it will correctly bold the field label and pull the text for the label out of the bond property?

you may need to set DataContext to the Dataform

The current item is set correctly, that is not the problem. It is with the design of the field, there's no way to tell what you're binding to.

Hi Stefan,

For example,

Please make sure that your DataContext or ItemsSource is ok.  You can get a working sample here.

Jonathan,

That does not address my question. The problem is that the field label does not pick up the validation properties of the property that I'm binding to and therefore bold the field label. In the example you have posted off that site none of the items are bold because validation properties not being used.

Not quite sure about what you want.

Please take a look at this video tutorial.   It shows you how to use validation on DataForm. For the ValidateProperty, please take  a look at this article.

Jonathan Shen – MSFT:

Not quite sure about what you want.  

if a property has the required attribute, e.g:

[Required()]

then the field label is automatically made bold, when you use one of the built-in field types. If you try and use a template field, as I have shown an example of above, the field label is not automatically made bold, because the field label does not know which property you are binding to.

There needs to be a way to tell the field label which property you are binding to so that can appropriately figure out if the attribute is required and bold itself.

Hi Stefan,

I have upgraded my Silverlight Tools to a internal version.  Seems DataForm stops working now. Since Silverlight 3 will be released very soon, would you please upgrade it and have a test.  If it doesn't work, please open a new thread and share the link with me.  Thanks for you understanding.

Best regards,

Jonathan

Jonathan,

I'm not quite sure what you would like me to upgrade to, I'm not aware of a later version of Silverlight 3 or the Silverlight 3 tools I can test with.  Can you let me know the URL where I can download the latest version? Currently running Silverlight 3.0.4037.0.  In Visual Studio (i.e Silverlight 3 tools):

Microsoft Silverlight Projects 2008
Version 9.0.30729.4063

Personally, I am very concerned that Silverlight 3 will be released without a release candidate, because there are a number of issues that I am not sure if they've been fixed in the final Silverlight release, and I'm also concerned that additional problems could be introduced.

Hi Stenfan,

Silverlight 3 RTW has not been released yet.  Anyway, it will be released very soon.

Best regards,

Jonathan
