AfterRowUpdate Event

Occurs after a row is updated, meaning changes made to its cells are actually committed to the data source.
Syntax
'Declaration
 
Public Event AfterRowUpdate As RowEventHandler
public event RowEventHandler AfterRowUpdate
Event Data

The event handler receives an argument of type RowEventArgs containing data related to this event. The following RowEventArgs properties provide information specific to this event.

PropertyDescription
Row The row (usually the row that the cell belongs to) (read-only)
Remarks

Therowargument returns a reference to an UltraGridRow object that can be used to set properties of, and invoke methods on, the row that was updated. You can use this reference to access any of the returned row's properties or methods.

This event is generated when a row is updated, meaning changes made to its cells are actually committed to the data source. Note that this is not necessarily when the row loses focus, since various factors such as the type of record locking employed by the data source, as well as the value of theUpdateModeproperty, can affect when the update occurs. TheBeforeCellUpdateevent is generated when a cell is accepting a new value.

To prevent the user from making changes to a cell, set theAllowUpdateproperty to 2 (AllowUpdateNo). A cell's value can be changed programmatically by setting itsValueproperty.

A row can be updated programmatically by invoking itsUpdatemethod.

TheBeforeRowUpdateevent, which occurs before a row is updated, is generated before this event.

If an error occurs while attempting to commit the changes to the data source, theErrorevent is generated.

Example
Following code shows some of the information available in AfterRowUpdate event. It gets the underlying DataRow associated with the row that was updated and prints out its RowState property. For this to work, the UltraGrid must be bound to a DataSet.
