WPF - how to use multiple data context for binding

Question

Please note: I have used Linq to SQL classes.so I have all my models created automatically

I have window that adds new products .so I have binded the controls on the form to Product Properties

this.DataContext =new tbl_Product();

Now I have some combo boxes on the same window like category n type I populate my combo boxes binding the item source to tbl_Category n tbl_Type

Now my issue is that I can only give one model as data context .if I give tbl_Category as data context I can't add products or if I give tbl_Products as data context then my combo boxes don't get populated.

Plz help me.Thanks in advance.

Set the datacontexts of the individual comboboxes to the required contexts rather that setting the data context at window level
