I see that the datagrid controls are there, however I am unable to use them in my web application form.

I was able to reference and Imports everything, but when it comes to using the actual elements I am stuck.

I have also attempted to manually type the xaml but with no luck it just shows everything as a non-element. 

The WPF DataGrid is not supported in WebForms/Applications.  It will only works in XBAP.

For the .NET Grid, it works only in .NET WinForms.  The only component that works in WebForms is the Chart for ASP.NET.
