Hi! I am Mashkoor a student of B.SC(IT). I am developing a Windows based application by using C# and SQL Server 2005.There are several forms in my application. In my application there is a data entry form by which the user can enter details of a student. In an another form i used a combobox control viz, 'Student Name', where I want to show all the student name by entering a single alphabet or character by which the Student Name begins. I have not written any code for that issue. Somebody please help me and provide code for that issue.
