Try this

C#

connection.Open();
SqlCommand cmd="Select * from table";
cmd.Connection=connection;
dropdown.DataSource=cmd.ExecuteReader();
dropdown.DataTextField="column to display";
dropdown.DataValueField="column to insert to DB";
dropdown.DataBind();

actually i dont want to insert to db..i want to retreive that in aspx page in drop down list??den wat u mean column to insert to db"??

Syed Salman Raza Zaidi 8-Feb-12 6:26am

for eg if you have two columns ID and Name and you want to display name on aspx page and id to insert to DB then datavalue field will be ID, since you dont want to insert any value to DB,therefore you can give any column name from query as DataValuefield ;)

means in my db table contains column UserName and column Role[true/fasle]..and i want to display username where role is false...

Syed Salman Raza Zaidi 8-Feb-12 6:41am

then your query should be select * from table where role=false, and you can give DataValuefield ="username";
