JS Grid Delegates
Published: May 2010
The JS Grid control supports a variety of delegates. Using these delegates provides you a greater degree of control over the behavior of the JS Grid control.
The following table lists the JS Grid delegates.
Delegate | Description |
|---|---|
AddColumnMenuItems(columnKey, fnInsertMenuItem, fnInsertSeparator) | Used when the column drop-down menu is activated. AddColumnMenuItems is called only if WillAddColumnMenuItems returns true for this column and if ExpandColumnMenu delegate is not present. |
AutoFilter(newState) | Called when a column header menu is pulled down and an autofilter item is selected. |
CreateEntryRecord() | Called as soon as some data is entered for a new row. |
DeleteRecords() | Called by the grid to request that the page delete currently selected records. |
ExpandColumnMenu(columnKey, position, fnOnMenuCollapsed) | This delegate is responsible for creating and rendering a column menu. |
ExpandConflictResolution | Internal only; this delegate is not intended to be used directly in your code. |
ExpandDelayLoadedHierarchyNode(recordKey) | Provides the ability to dynamically modify the hierarchy. |
Filter | Internal only; this delegate is not intended to be called directly from your code. |
GetAutoFilterEntries (currentAutoFilterState, initiatingColumnKey, columnKeys, fnSuccess, fnFailure) | Called when the column menu is dropped down and the grid needs to populate the autofilter entries in the menu. |
GetGridRowStyleId() | Called to get row style information. |
GetRecordEditMode(record) | This delegate is called for each cell of a line when the line is rendered. It is also called if a cell is being selected. |
IndentRecords () | Called when the grid is requesting the controller to indent the currently selected records. |
InsertRecord() | Called when the grid is requesting the page to insert a record at the currently selected row. |
LaunchFilterDialog(colKey) | Called when there are too many autofilter entries to display. |
OutdentRecords() | Called when the grid is requesting the controller to outdent the currently selected records. |
ShowColumnConfigurationDialog() | Show a custom column configuration dialog. |
Sort(array) | The page is asking the grid to sort, passing in an array of objects. |
TryInsertEntryRecord(entryRecord, entryRecordPropertyUpdates, fnRecordCommitSucceeded, fnRecordCommitFailed.) | Called as soon as the user leaves the newly created row. This delegate ends the sequence initiated with the delegate of type CreateEntryRecord. |
