ObjectDataSource not calling Insert method when it has extra parameters
asp.net, objectdatasource
Solution
I also had trouble inserting record, however, I found out after testing for a while and google a bit, that if your specify 'DataObjectTypeName' parameter in ObjectDataSource, InsertParameters get ignored. So I just don't specify that, and it works for me.

Problem
I'm new to ASP.NET, and I'm trying to implement a custom ObjectDataSource Insert method. The default business method works fine (with a single object parameter). However when I add an extra parameter, the business method does not get called. Here is my code - Insert() always gets called, but InsertWithParams() never does. ``` // Business Layer public class MyObject { public MyObject() {} public string Foo { get; set;} } namespace MyLogic { public static Insert(MyObject m) { // ... do DB insert } public static InsertWithParams(MyObject m, string p) { // ... do more fancy DB insert } } // MyLogic ``` Given the following ObjectDataSource declaration, "InsertWithParams" and "MyObjectDS_Inserting" are never called. However if "MyLogic.Insert" is specified instead, it does get called along with the event. Also If I remove the p parameter from InsertWithParams, it does get called. ``` <asp:ObjectDataSource runat="server" ID="MyObjectDS" TypeName="Business.MyLogic" DataObjectTypeName="Business.MyObject" InsertMethod="InsertWithParams" OnInserting="MyObjectDS_Inserting" > <InsertParameters> <asp:Parameter Name="m" Type="Object" /> <asp:Parameter Name="p" Type="String" /> </InsertParameters> </asp:ObjectDataSource> ``` So it seems in this case I can't add parameters to an insert method in an ObjectDataSource. Adding or removing declared InsertParameters does not seem to make a difference.
