Question

ddlstate.DataSource = ds;
ddlstate.DataTextField = "sname";
ddlstate.DataValueField = "sid" ;
ddlstate.DataBind();

Answer 1

I think the error is "object name,state1" in which case the error is being thrown from your database because it can't find a table or view called state1. Please check that you are connecting to the correct database or if your table is in another schema apart from dbo, that you use the schema qualified name eg schemaname.state1

Answer 2

I think this may be the problem:

SqlDataAdapter da = new SqlDataAdapter("select * from state1",con);
DataSet ds = new DataSet();
da.Fill(ds,"state1");
ddlstate.DataSource = ds;//------------------> I think this one is worng. It should be table i.e. ds.Tables[0]/ds.Tables["state1"] if "ds" is not null.
ddlstate.DataTextField = "sname";
ddlstate.DataValueField = "sid" ;
ddlstate.DataBind();
