WPF Datagrid - make auto generated column(s) be required

Question

I have a datagrid in a wpf application where AutoGenerateColumns="TRUE". I would like to set some or all of them to be required and invalidate if something is missing.

I was hoping there would be something like: dgrid.Columns(_DataTable.Columns("fname").Ordinal).required = TRUE

Is required used to specify that the value is required when editing a row? Validations are not done this way...

You can take a look here http://blogs.u2u.be/diederik/post/2009/09/30/Validation-in-a-WPF-DataGrid.aspx if this is what you need.

I am looking at this, but it hasn't helped me yet. Partially because the columns are auto generated. I will keep reviewing it to see if I can glean what I need from it. It certainly looks like it will help me in other situations though. – donL Mar 29 '13 at 17:23

Okay, and then when I get the e.column what do I use to set it as required? – donL Mar 29 '13 at 16:47
Based on the question I assumed Required was a Property of a DataGridColumn but it is not so I don't understand the question. – paparazzo Mar 29 '13 at 16:57
".required" is an example of something like what I would hope existed – donL Mar 29 '13 at 16:58
