How are you binding the data columns from datasource, through the Bound Field or template fields with customized html ? | | - Mark | Empty Data Text="the cart is empty" On Page Index Changing="grid Cart_Page Index Changing" On Row Canceling Edit="grid Cart_Row Canceling Edit" On Row Deleting="grid Cart_Row Deleting" On Row Editing="grid Cart_Row Editing" On Row Updating="grid Cart_Row Updating" Hi Mark, Thanks for your response and the code you provided, so you're using a custom class collection without using any Data Source control, I think this should be the cause of the parameters collection in Row Updating event being empty. Anyway, you can also add the suggestion on the MSDN feedback center.

Also, if convenient, would you post some detailed code snippet of your page and the code behind on this? All the parameters are actually associated to the Parameters declared in Data Source control (the select and update statement in Data Source control), also we can find some parameter name related attribute such as Old Values Parameter Format String="original_" So when we do not using Data Source control, there is no info for populating named parameters .... Also, I think it'll still require us to use Data Source Control when we need to Updating event to contains Parameters collection, however, it may become more user friendly if there're some additional functions on the Data Bound control which can help extract bound values from each row /column... ha AJ9Znc P8Ei3q L2 n GKN1K6B5U57An5w PDTl Bf TR hgoc D5IBPrxek8Ok Q6ARdran47 nw== | X-Complaints-To: ab***@| X-DMCA-Notifications: X-Abuse-and-DMCA-Info: Please be sure to forward a copy of ALL headers | X-Abuse-and-DMCA-Info: Otherwise we will be unable to process your complaint properly | X-Postfilter: 1.3.32 | Path: TK2MSFTNGXA02gbl!
