Solution 1

I guess you populate data using a query.
Sort the data in this query.

If you want to sort on client side, then sort the returned collection using LINQ.

Yes, it is working now. I used LINQ.

Solution 2

try this

DataTable Dt = new DataTable();//where all data is saved to show in combobox
Dt.Columns.Add("Id");
Dt.Columns.Add("Name");
Dt.Rows.Add("0","Stephan");
Dt.Rows.Add("1","Antony");
Dt.Rows.Add("2","Mike");

Dt.DefaultView.Sort = "Name ASC";//This will turn your record in ascending order

combobox1.DataSource = Dt;
combobox1.DisplayMember="Name";
combobox1.ValueMember="Id";
