Sqldatasource formview update

You can handle this event to examine the values of the parameters and to perform any preprocessing before an Update operation. After the Update operation completes, the OnUpdated method is called to raise the Updated event.

You can handle this event to examine any return values and error codes and to perform any post-processing. To perform an update operation, the SqlDataSourceView builds a DbCommand object using the UpdateCommand text and any associated UpdateParameters properties, and then executes the DbCommand object against the underlying database. Values are inserted into parameters without validation, which is a potential security threat.

Use the Updating event to validate parameter values before executing the query. For more information, see Script Exploits Overview. Skip to main content. This browser is no longer supported. Download Microsoft Edge More info.

Put breakpoints in them, and use the debugger to see if the events fire at all. When they do, examine the data in the event arguments.

See if there is anything that isn't what you expect. Yes it can. SqlDataSource will make a Parameter for each declared Parameter. It will also make a Parameter for each value it gets handed by FormView. If there is an overlap in names, the value from FormView will overwrite the declared value. You can use this to set default values for fields that may not be passed and for getting data from outside the FormView.

If all data is coming directly from the FormView, and no default values are needed, it is not necessary to declare Parameters. SqlDataSource can make them all from what FormView passes to it. If FormView is sending something you don't want, look at the FormView and see if the field is either in DataKeyNames, or has a Bind databinding expression on it.
