Bind gridview to stored procedure in code behind

I have a form with 4 dropdownlists and a gridview.  I also have a find button
Each dropdown is bound to it's own linqdatasource.
The gridview is not bound yet.
I need to filter by none to all of the dropdownlist selections, so I created a stored procedure with conditional where clause.
Now I need to know how to bind the grid to the stored procedure.
Everything I have tried returns an error on Bind.
How do I bind a grid to a stored procedure?
Thanks

What did you try and what is the error you are getting?
Can you try this:
Me.GridView1.DataSource = dc.stp_FindStylist(iProfCat, iStateID, iCityID, sSalon)
OR
Me.GridView1.DataSource = dc.stp_FindStylist(iProfCat, iStateID, iCityID, sSalon).ToList()

I tried both.  My latest error is
DataBinding: 'stp_FindStylistResult' does not contain a property with the name 'StylistID'.

Stylist ID is included in the sp and I changed the exec( @sql ) to Select @sql in the stored procedure.

Thanks

can you adjust your select like this:
dbo.Stylists.StylistID as StylistID

I now get the error
Data source is an invalid type.  It must be either an IListSource, IEnumerable, or IDataSource.

I don't have to tolist() option, so it is...
Me.GridView1.DataSource = dc.stp_FindStylist(iProfCat, iStateID, iCityID, sSalon)
