Dear Friend,

Have you tried something earlier. If not then try atleast and then if you face some problem then do share your problem with us here.

You can go either way means, making a SP or writing a query will do but SP will be preferable.

Thanks

int Value=Convert.ToInt32(ddlTestCase.SelectedValue.ToString());
DataSet ds=new DataSet();
SqlConnection con = new SqlConnection();
SqlDataAdapter da = new SqlDataAdapter();
con.ConnectionString = ConfigurationManager.ConnectionStrings["MyConStr1"].ConnectionString;
SqlCommand cmd = new SqlCommand();
con.Open();
cmd.CommandType = CommandType.Text;
cmd.CommandText = "select AllocaterName from WorkAllocated where ID=" + Value;
//SqlDataAdapter da =new SqlDataAdapter("select AllocaterName from WorkAllocated where ID=" + Value);
da.Fill(ds);

if(ds.Tables[0].Rows.Count >0)
{
lblAllocater.Text=ds.Tables[0].Rows[0]["AllocaterName"].ToString();
}
