The Update method updates any modified information in the grid, sending it to the data provider. When the update is complete, any rows that were marked as having modified data will have that mark cleared. The DataChanged property will be set to False.
Normally, the grid handles the updating of data automatically, so there will be few situations in which you will need to invoke this method. The major exception is when you have set the UpdateMode property to 'OnUpdate'. When using that setting, the grid will not send any data to the data provider until you invoke the Update method. You must use the method to manually update the data provider whenever data has been changed and you are ready to commit the changes.
