Hello!
I am trying to learn how to use the Silverlight 3 DataForm control, because I need to define the DataForm fields myself in the XAML code, that is, I don't want to use the AutoGenerateFields property.
My problem is: the dataform works perfectly when the AutoGenerateFields is set to true, but when I create a DataForm and set the fields manually and run the application, all I get is an empty blank rectangle where my form and its fields should be.
I created a blank Silverligh Navigation Application to test this, and below is the code of the Home.xaml page:
<Grid x:Name="LayoutRoot">
<StackPanel>
<!-- This doesn't work. It renders a blank rectangle -->
<dataFormToolkit:DataForm x:Name="DataForm">
<dataFormToolkit:DataForm.EditTemplate>
<DataTemplate>
<StackPanel dataFormToolkit:DataField.IsFieldGroup="True">
<dataFormToolkit:DataField>
<TextBox Text="Test1" />
</dataFormToolkit:DataField>
<dataFormToolkit:DataField>
<TextBox Text="Test2" />
</dataFormToolkit:DataField>
<dataFormToolkit:DataField>
<TextBox Text="Test3" />
</dataFormToolkit:DataField>
</StackPanel>
</DataTemplate>
</dataFormToolkit:DataForm.EditTemplate>
</dataFormToolkit:DataForm>
<!-- This works. -->
<dataFormToolkit:DataForm x:Name="DataForm2"/>
</StackPanel>
</Grid>
To make the second DataForm work, I simply created a Person class, and put the following in Home.xaml.cs:
protected override void OnNavigatedTo(NavigationEventArgs e)
{
Person client = new Person { Age = 10, DateOfBirth = new DateTime(1980, 10, 20), FirstName = "John", LastName = "Doe" };
DataForm2.CurrentItem = client;
}
You can see what happens when I run the application in the following link: http://dl.dropbox.com/u/1946004/image.PNG (I don't have enough points to post images, so...)
Does anyone know what's wrong? Thank you in advance.
