How to Bind a Label to the Count of a Datatable

Question

I have built a Windows Form in VS2010, .NET 4. My project trolls through files, and when signifcant information is found, creates a row in a datatable. That all works fine.

I would like to have a label on the form show the number of records in the datatable, as they are added to the table. I have had lots of fun connecting datagrids to datatables and textboxes to values in a column for the current record in a bindingsource, but this one eludes me when I thought it would be simpler. I think I know how to do this in code, but before I go down that track, I seem to feel this would be really easy in the designer. Is it possible?

I've created a BindingSource object connected to the datatable, but I cannot seem to get other than row values by assigning the DataSource of the Label to the BindingSource. I want the count so that when the other thread is updating the table, my form will automatically update with it.

Thanks for the response, Mitja, but it wasn't what I was looking for. I had asked if there was a way through the Designer because I had setup everthing else in my project that way and prefer to have all settings done in Designer, if possible (just for organisation sake). I had already started on writing code for an alternative as I suspected that there wasn't a way to do it. My solution wasn't using a wrapper, but I stopped and tried it, but it didn't work for me with a datatable (though it has an appropriate interface). I didn't want to fuss, so I went back to a simpler method and might try this again some day. Since yours is the only answer and indirectly answers my question, I'll mark it as the answer.

Appreciate the quick response.
