To edit a cell value at runtime, an end-user must focus it and press Enter, or double-click this cell. Columns utilize Dev Express Editors, and optionally, more complex Dev Express controls to display and edit data source records.Columns automatically choose editors depending on the column data type.The Dev Express editors have corresponding repository items - objects that store main editor properties.
To avoid this we need to keep the property Read Only as false, Then in the edit mode nothing will happenes. The reason I use Template Field instead of Bound Field is that, it is very easy to grab those controls in the codebehind if we user labels or textboxes.To manually trigger row validation, call the Column View.
