how to bind data coming from sql server database into dropdown of html 5 with text and value format like asp.net dropdown list .

Get data from sql server through data source(ds) and bind it with dropdown list e.g
ddl->dropdown list name in html
ds->data source for dynamically getting data from server
tl->name of the table
city and cityCode->two column of a table
ddl.DataSource = ds.Tables["tl"];
ddl.DataTextField = ds.Tables["tl"].Columns["city"].ColumnName.ToString();
ddl.DataValueField = ds.Tables["tl"].Columns["cityCode"].ColumnName.ToString();
ddl.DataBind();

I hope this may help you!!
