>I guess I haven't tried to do this before. I would like to display a boolean field in a data grid with a checkbox. I added a checkbox type column to the grid and bound it to a boolean field but it just shows up as dimmed out. What is the process for doing this?

well, checkbox type columns show up as dimmed out (in other words: disabled or readonly) like any other column in the grid
If you want it to be enabled, you need to "Edit" that particular row!
As an alternative, you can create a template column with a bound checkbox inside. In this case, all checkboxes in this columns show up as enabled, but you have to care about saving the checked status changings on your own.

>How about if I want to display an enumeratin value that corresponds to an integer in the data within a datagrid? So if I have a type column that can be a 0, 1, or 2 value but I want to display in the datagrid "Message", "Tip", "Location".

if you simply want to display these values, you can (again) create a template column with no control inside.
In the RowDataBound event of the gridview, you can modify the "Text" property of the "cell" in that particular column.
