I am putting a silverlight 3 video to practice in silverlight 4 as my pc doesnt have SL 3.
This however doesnt seem to work the same way for Silverlight4.

1.) I couldnt find the dataform control in the same namespace System.Windows.Controls as mentioned in the video, had to get it by drag-dropping from exp. blend 4.

2.) The dataform control that loads when I run the application doesnt have the save button or the edit link.

3.) Also, the bindable property set to oneway doesnt make the field read-only.

Is this by design or do I need to reinstall something. My win7 pc does not have VS2008 IDE or Silverlight 3 tools/sdk/toolkit installed, only VS2010 with Silverlight 4 and Expression blend 4.

    The DataForm control is the System.Windows.Controls namespace but its found in the System.Windows.Controls.DataForm.Toolkit.dll assembly. However this is the same whether you are using the latest Nov09 Toolkit (for Silverlight 3) or Apr10 Toolkit (for Silverlight 4).

    The video is aging a little now, I think it was the Oct09 toolkit which introduced the .Toolkit suffix for assemblies in the toolkit and that video doesn’t show that.

    Since DataForm is still at Preview quality you can expect that a number of things may have changed about how it behaves since the video was created.
