Simple ASP Datagrid question - User input

Question

I am designing an ASP interface in which user should enter input in datagrid. Here is what I am working on There is one table “table 1”which contains two fields – Author and Title. There is another table “table 2” which contains two fields – Author and Awards. (One Author may have multiple awards) On my form datagrid contains three columns. In First two columns data comes from the table “table1”. In third column of the datagrid I want user to enter the award name. When user hits enter or save button on the form, I want to validate the user input against “table 2”. (To check if that author has that award or not). I am not sure what kind of column (Bound column etc) should I use to let user enter the input. What would be the best way to do this…..Please help. Thank you. C_sharpkid
