    <p>so I am using Gridview with a WCF. I have managed to insert from textboxes to gridiview but now I am struggling to save the gridview via the WCF service. I have giving it an attempt and getting this error:</p> <blockquote> <p>"The parametrized query '(@Item1 narchar(4),@Item2 nvarchar(4000)) insert into ' expects the parameter '@item2', which was not supplied."</p> </blockquote> <p>here is my code:</p> <pre><code>public string InsertProcesses(ProcessDetails proDetails) { string Message; SqlConnection con = new SqlConnection(@"Data Source=localhost;Initial Catalog=WCFTest;Integrated Security=True;Pooling=False"); con.Open(); SqlCommand cmd = new SqlCommand("insert into SaveProcesses(Item1, Item2)values(@Item1, @Item2)", con); cmd.Parameters.AddWithValue("@Item1", proDetails.Item1); cmd.Parameters.AddWithValue("@Item2", proDetails.Item2); int result = cmd.ExecuteNonQuery(); if (result == 1) { Message = proDetails.Item1+ "Details accepted"; } else { Message = proDetails.Item1+ "Details not accepted"; } con.Close(); return Message; } for (int i = 0; i &lt; dataGridView2.Rows.Count; i++) { ServiceReference6.ProcessDetails det2 = new ServiceReference6.ProcessDetails(); det2.Processes = dataGridView2.Rows[i].Cells["Item1"].Value.ToString(); det2.Processes = dataGridView2.Rows[i].Cells["Item2"].Value.ToString(); obj6.InsertProcesses(det2); </code></pre> <p>Thanks for any help that can be given. Please note this is my first time attempting a WCF.</p> <p><strong>ProcessDetail code</strong></p> <pre><code>[DataContract] public class ProcessDetails { int id; string item1; string item2; [DataMember] public int Id { get { return id; } set { id = value; } } [DataMember] public string Item1 { get { return item1; } set { item1 = value; } } [DataMember] public string Item2 { get { return item2; } set { item2 = value; } } } </code></pre>

    3. COYou have a SQL error, not a WCF error. What you expect to be happening with Item2 is not happening. What is `det2.Processes`? whatever it is, you're overwriting it in your for loop when you assign the "item2" cell to it. Can you post more of your code?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
