Question

My code for sql connection using linq is:

var query1 = from u in dc.Usage_Computers           where u.DomainUser == s3           select u; // selects all feilds from table  GridView1.DataSource = query1; GridView1.DataBind(); 

I have a field called ‘Operation’ in the table ‘Domainuser’ which has values like ‘1, 2, 3’. When I populate these values to data grid I wanted to convert them to meaningful values like if the value of Operation is 1 then display in datagrid as ‘logon’, if 2 then ‘logoff’ etc…

How do i assign values for them after retrieving from database?

This technique does not seem particularly applicable to your problem, but here it is anyway.

You can create a SQL case statement in LinqToSql by using the C# ? : operator.

var query1 =   from u in dc.Usage_Computers   where u.DomainUser == s3   select new {usage = u,      operation =       u.DomainUser.Operation == 1 ? 'login' :       u.DomainUser.Operation == 2 ? 'logoff' :       'something else'   };
