Differences between htmldatacellprepared events and Celleditorinitialize events used in DevExpress in GIRDVIW

The Htmldatacellprepared event initializes the page when the page is displayed (changes the ID to name)

? The Celleditorinitialize event is the initialization of the page when it is edited (added, modified), such as filling the value into a drop-down list.

///

The name of the department that initializes the grid

if (E.datacolumn.fieldname = = "Depid")

{
