Does anyone know the issue with this code. I am trying to to display a datagrid from a stored procedure on a button click in the WebApp using C#. I have used this code developing a form and it worked perfect but won't translate to the WebApp . My connections are are set up correctly. cs is my connection da is my DataAdapter ds is my Dataset MessageBox is declared in a previous class and works correctly. The stored procedure executes correctly because I have checked my tables in the database that update on the button click. I just want to display the results on my WebApp. Any suggestions? Code: protected void Button2_Click1(object sender, EventArgs e) { da.SelectCommand = new SqlCommand("execute spTEST", cs); cs.Open(); da.Fill(ds); dg.DataSource = ds.Tables[0]; MessageBox("SUCCESS!"); cs.Close(); }
