Difference between GridView and DataGrid
|Sorting, and in-place editing of data requires additional coding.
||It enables you to add sorting, paging and editing features without writing any code. We can enable these features by setting properties on the control.
DataGridcontrol can declaratively bind a
DataSourceControlcontrol, it can do so only for data selection. Sorting, paging, updates, and deletions must be written manually.
GridViewcontrol supports a
DataSourceIDproperty that can be set to any object that implements the
IDataSourceinterface and can, therefore, take advantage of the data source control's sorting, paging, updating, and deleting capabilities, for example, the
DataGridcontrol requires additional coding for paging.
GridViewcontrol automatically supports paging by setting the
AllowCustomPagingproperty must be set to
truefor custom paging.
|Custom paging support in the
GridViewis supplied by the bound data source control.
|It raises single events for operations such as sorting, updating.
||Gridview raises pre-operation and post-operation events such as sorted, sorting events for sort command, updating and updated events for Update command.
