Hi,

I have a grid bound to an objectdatasource.
I represents a shoping cart. Now my problem.

The cart class (reduced) 3 properties:
CartID, LineNumber, NumItems
Only NumItems is editable the other fields are readonly.
There is a static method called "UpdateNumItems" definedt like this:

public static int CartLinesChangeNumItems(string strCartID, int nLineNumber, int nNumItems) {  
... 
When I update in the grid it tells me "There is no generic method accepting strCartID, nLineNumber, nNumItems, NumItems, LineNumber, CartID
This is when I set (what's correct) CartID and NumItems as DatakeyNames.
If I remove the datakeyNames I get There is no... accepting strCartID, nLineNumber, nNumItems, NumItems

So I guess Grid uses the Parameters from the update parameters - and it adds his fields to this collection.

My Question now - how can I tell Grid the "translation" -- so I can Say NumItems is Parameter strNumItems.

Of course I could change the parameter names on the functions (then it works) -- but what if I am not able to do this?

Regards

Manfred

Hello Manfred,

Based on this information, it is hard to determine how the grid is setup, and how the object datasource is configured. If the problem persists, you can open a formal support ticket, and send us a small project, demonstrating your approach, along with the generated exceptions.

Best wishes,
