If you are using Windows Forms, have a look at: ComboBox.DataSource Property[^]

If you are using ASP.Net, have a look at: Binding ASP.NET DropDownList to data structures[^]

The above examples shows how to bind to lists - and below you'll find an example of how to retrive a list of records from a database:

Youu can use this code where you want OnPageLoad etc

Dataset Ds =new Dataset();
sqlDataadpter ad=new sqldataadpter("select column1,column2 from table1",con);
ad.fill(Ds);

DropDownList1.datasource=Ds.tables[0].defaultview;
DropDownList1.DataBind();
DropDownList1.DataTextField=Ds.table[0].column["column1"].tostring();
DropDownList1.DataValueField=Ds.table[0].column["column2"].tostring();
