Solution 1

may be you are asking this

SqlConnection con = new SqlConnection("<connectionstring>");
SqlDataAdapter ad;
DataTable dt = new DataTable();
ad = new SqlDataAdapter("select Rollno from Student",con);
ad.Fill(dt);
comboBox1.DataSource=dt;
comboBox1.DisplayMember="Rollno";//column name of DataBase Table
comboBox1.ValueMember="Rollno";//column name of Database Table


</connectionstring>

Getting Error at Rollno doesnot exist in the current context.

If that is the error, it's not because of your mistake. He answered correctly. You are an idiot to just copy-paste the whole thing, and when it gives error you vote him down!

You need to change the query to whatever columns you want to fetch data. Run the query first, see the data and then use the same query.

Removed the 2-vote given by OP as it was not your mistake.

"RollNo" is the name of the DataBase Column ....i think you have posted the Structure of DataBase table of "Student" as Rollno,Name and FatherName as three columns, "Rollno" is one of those columns
