ObjectDataSource not calling Insert method when it has extra parameters
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 i开发者_运维百科t 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.
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.
