by writing the connection string on the click event of the
button. by connection string i mean it's the ado.net
structure.firstly you have to include the namespace- using
system.data.sqlclient;
now on the click event of the button( eg u have taken a
sumbit button ) you will be writting- sqlconnenection con=
new sqlconnection........then u'll use
datacommand,dataset,string,databind,gridview.
u can also use read for getting the errors in a specified
manner.for this u will be using try and the catch then your
connection string code and then u'll use the finally
function and then close().
