A single component often uses a number of interfaces.
|
||
|
|
||
|
### GridField_HTMLProvider
|
||
|
|
||
|
Provides HTML for the header/footer rows in the table or before/after the template.
|
||
|
|
||
|
Examples:
|
||
|
|
||
|
- A header html provider displays a header before the table
|
||
|
- A pagination html provider displays pagination controls under the table
|
||
|
- A filter html fields displays filter fields on top of the table
|
||
|
- A summary html field displays sums of a field at the bottom of the table
|
||
|
|
||
|
### GridField_ColumnProvider
|
||
|
|
||
|
Add a new column to the table display body, or modify existing columns. Used once per record/row.
|
||
|
|
||
|
Examples:
|
||
|
|
||
|
- A data columns provider that displays data from the list in rows and columns.
|
||
|
- A delete button column provider that adds a delete button at the end of the row
|
||
|
|
||
|
### GridField_ActionProvider
|
||
|
|
||
|
Action providers runs actions, some examples are:
|
||
|
|
||
|
- A delete action provider that deletes a DataObject.
|
||
|
- An export action provider that will export the current list to a CSV file.
|
||
|
|
||
|
### GridField_DataManipulator
|
||
|
|
||
|
Modifies the data list. In general, the data manipulator will make use of `GridState` variables
|
||
|
to decide how to modify the data list.
|
||
|
|
||
|
Examples:
|
||
|
|
||
|
- A paginating data manipulator can apply a limit to a list (show only 20 records)
|
||
|
- A sorting data manipulator can sort the Title in a descending order.
|
||
|
|
||
|
### GridField_URLHandler
|
||
|
|
||
|
Sometimes an action isn't enough, we need to provide additional support URLs for the grid. It
|
||
|
has a list of URL's that it can handle and the GridField passes request on to URLHandlers on matches.
|
||
|
|
||
|
Examples:
|
||
|
|
||
|
- A pop-up form for editing a record's details.
|
||
|
- JSON formatted data used for javascript control of the gridfield.
