VB.Net Gridview Combobox column

Hi
I am using GridView control with 4 textbox and 1 combobox cell type.  In the combobox, I've added some items in the design time. Let's say,  3 products like keyboard,mouse,printer.

Now, I want to load data into the gird from database using bound method.  In this case, If my database values is "mouse", then the 2nd item of the combobox sould be selected when boound data.

How can i achieve it.  Pls help me to provide some sample code.
