Place your perform File Upload() somewhere else on in inserting or updating event . I put a break point in the Item Command and in the Proform Upload method and somehow it bi-passes everything and just gave me the error. In previous tutorials we learned how the Object Data Source control allowed for inserting, updating, and deleting of data.event to perform additional initialization operations that are specific to your application, to validate the values of parameters, or to change the parameter values before the Sql Data Source control performs the update operation.The connection to the underlying data source is not yet open when the event handler delegate is called.How do I cancel the any Update or Insert if certain criteria failed during my code behind checking? If the upload failed to occur, I want to cancel any update/insert in code behind. Or If possible insert/update the records after the upload completed Hope this will helpful for you That's what I I'm trying to do; however, I don't know where in the process is the insert/update occur.I use the Form View_Item Updating and Form View_Item Inserting method to perform my file upload if there is any.With the Sql Data Source, we need to provide SQL statements (or stored procedures) to execute.

Figure 5: Clicking the Delete Button in the Grid View Invokes the Sql Data Source s SQL statements can be specified through the Properties window or the control s declarative syntax.

For now, let s use the Properties window in the Designer, although the Configure Data Source wizard or declarative syntax option would work just as well.

From the Designer in Sql Data Source and then bring up the Properties window (from the View menu, choose Properties window, or simply hit F4).

The example shows how you can use a Db Transaction object to add transaction context when using the Sql Data Source control to update data.

I have a SQLData Source control and a form View control. Hi try Transaction concept of the database like while insert/update use the Begin transaction If your process get succeed then use commit Transaction Or else use rollback transaction which revert back all your changes up to the start transaction.

Our goal is to extend this example to allow for the user to delete products via the Grid View.
