This default behavior makes little sense because you might end up with some rows (all those preceding the conflicting one) sent to the database correctly and others (those that follow the conflicting one) that aren t sent, even if they wouldn t raise any conflict. In most cases, you want to try the update operation on all the rows in the DataTable instead of stopping the operation at the first row that fails to update. You can do this by simply setting the DataAdapter s ContinueUpdateOnError property to True. In this case, you can test whether one or more rows failed to update by checking the DataSet s HasChanges property:

protected object Eval(string expression) { if (Page == null) throw new InvalidOperationException( ); return DataBinder.Eval(Page.GetDataItem(), expression); }

da.ContinueUpdateOnError = True da.Update(ds, Authors ) If ds.HasChanges() Then One or more rows failed to update. End If

As you can see, Eval is a simple wrapper built around the DataBinder.Eval method. The DataBinder.Eval method is invoked using the current container s data item. Quite obviously, the current container s data is null outside a data-binding operation that is, in the stack of calls following a call to DataBind. This fact brings up a key difference between Eval and DataBinder.Eval.

The pseudocode that illustrates the behavior of the page s Eval method shows a GetDataItem method from the Page class. What is it As mentioned, the simplified syntax assumes a default Container.DataItem context object. GetDataItem is simply the function that returns that object. More precisely, GetDataItem is the endpoint of a stack-based mechanism that traces the current binding context for the page. Each control in the control tree is pushed onto this stack at the time the respective DataBind method is called. When the DataBind method returns, the control is popped from the stack. If the stack is empty and you attempt to call Eval programmatically, GetDataItem throws an invalid operation exception. In summary, you can use the Eval shortcut only in templates; if you need to access properties of a data item anywhere else in the code, resort to DataBinder.Eval and indicate the data item object explicitly.

You can get more granular control over what happens when an update is attempted by trapping the RowUpdated event. This event lets you detect the conflict and decide to continue the update operation with the remaining rows if possible.

The ASP.NET Web Forms model was originally devised to bring the power of RAD to the world of the Web. Hence, the quest for productivity was the primary driving force behind most of the features that still represent the major characteristics and pillars of ASP.NET. There are three pillars to the Web Forms model: page postbacks, view state, and server controls. They work together according to the model depicted in Figure 1-1.

When an Update command is issued, the DataAdapter object fires a pair of events for each inserted, modified, or deleted row in the table being updated. The RowUpdating event fires before sending the command to the database, whereas the RowUpdated event fires immediately after the database has processed the command. The object passed as the second argument to the RowUpdated event exposes the following prop erties: StatementType (an enumerated type that specifies the type of command: insert, delete, or update); Command (the ADO.NET Command object sent to the database); Row (the DataRow being updated); TableMapping (the DataTableMapping object used for the update operation); RecordsAffected (the number of records affected by the update operation); Errors (the collection of errors generated by the .NET Data Provider during the update operation); and Status (an enumerated value that specified how to handle the current row; can be Continue, ErrorsOccurred, SkipCurrentRow, or SkipAllRemainingRows). The object passed as the second argument to the RowUpdating exposes the same properties, except RecordsAffected and Errors. The key value to test from inside the handler of the RowUpdated event is the RecordsAffected property. Any value less than 1 in this property means that the command failed and that there is an update conflict. This is the usual sequence of operations you perform inside a RowUpdated event handler:
