Datagrid Validation

[HoytG1949]

I have created an editable datagrid in ASP.NET using VB syntax. I want to validate what the user enters before I update the table in my SQL database. Some examples of what I need to validate for are:<BR>- a two character field<BR>- a number that must be 11 digits<BR>- an email address<BR><BR>Can anyone out there help me?<BR><BR><BR>Thanks in advance,<BR><BR>Tina
