Question

I am attempting to learn ASP.NET and want to use an ObjectDataSource to select and insert into a database. I am using a business class that has an insert method that has an object as its parameter. Several sources I’ve looked at say that this is a correct way of doing this but I have been unable to find out how to insert into the database using c# in the code behind file. I have a form that pulls from two other tables using ObjectDataSources that work correctly but I need to use a button to insert the record that I am creating into the table. I do not seem to be able to add the object I have created into the InsertParameters of the ObjectDataSource so I want to know if there is a method of doing this.

The insert method’s signature looks like this:

public static void InsertIncident(Incident incident)

The ASP code that Visual Studio generated looks like this:

<asp:ObjectDataSource ID="ObjectDataSource1" runat="server"
  DataObjectTypeName="Incident" InsertMethod="InsertIncident"
  OldValuesParameterFormatString="original_{0}"  SelectMethod="GetIncidents" 
  TypeName="IncidentDB"></asp:ObjectDataSource>

Answer 1

I feel a little bit silly now, but I found out what I was doing wrong. I didn’t need to use the ObjectDataSource for inserting the object at all. I should have just called the insert method directly.

if (IsValid)
{
  Incident i = new Incident();
  i.CustomerID = Convert.ToInt32(ddlCustomer.SelectedValue);
  i.ProductCode = ddlProduct.SelectedValue;
  i.DateOpened = DateTime.Today;
  i.Title = txtTitle.Text;
  i.Description = txtDescription.Text;

  try
  {
    IncidentDB.InsertIncident(i);
  }
  catch (Exception ex)
  {
  }
}
