Adds a class or multiple classes (separated by empty space) to a row or cell. Either rowData or rowIndx can be passed.

• rowData
  Type: Object or Array
  Reference to 1-dimensional array or object representing row data.
• rowIndx
  Type: Integer
  Zero based index of the row.
• dataIndx

• cls
  Type: String
  Name of a single class or more classes separated by space.
• refresh
  Type: Boolean
  Optional parameter with default value of true.

Code examples:

Invoke the method:

//Add classes 'pq-delete' & 'pq-edit' to 3rd row.
grid.addClass( {rowIndx: 2, cls: 'pq-delete pq-edit'} );

//Add a class 'pq-delete' to 'profits' field in 3rd row
grid.addClass( {rowIndx: 2, dataIndx: 'profits', cls: 'pq-delete'} );

(v6.0.0) Add or insert new nodes/rows in the grid. New rows are inserted at passed rowIndx, they are appended when rowIndx is not passed. It works similar to addRow except that ui.source value is "addNodes" in the events fired during the process.

• nodes
  Type: Array
  Array of nodes or rows.
• rowIndx
  Type: Integer
  Zero based index of the row.

Code examples:

Invoke the method:

grid.addNodes([{}, {}], 10);

Appends a row or multiple rows to the local data and returns rowIndx of the added row or inserts a row or multiple rows at rowIndx if rowIndx is/are provided.
newRow is the data contained in the new row. It was named rowData in versions prior to 3.2.0.
rowList can be used instead of rowIndx, newRow while adding/inserting multiple rows at once as shown in below examples.
The tracking of this operation for commit and rollback is determined by trackModel.on option unless overridden by track parameter passed to this method.
If source parameter is passed, its value is available in the change event instead of default add value when new row is added by this method.
If history parameter is passed, this operation is added to the history or not depending upon value of the parameter.
checkEditable parameter affects the checks for editability of cells.
By default the view is refreshed by this method which can be prevented by passing refresh parameter as false to this method.

Change Log: v3.2.0:

1. rowList parameter is added to support multiple rows.
2. rowData parameter is renamed to newRow. It's backward compatible and previous versions should use rowData.

Added in v5.2.0, it returns checkbox column instance on which further checkbox manipulation methods can be called.

Note that this is used only for non-heirarchical checkboxes. For hierarchy checkboxes like that in case of treegrid and row grouping, use checkbox related methods of grid.Tree() and grid.Group().

    var Checkbox = grid.Checkbox( 'ShipCountry' );

beforeCheck, beforeValidate, change and check events are fired when checkAll, checkNodes, unCheckAll, unCheckNodes methods are called.

Individual checkboxes can also be checked / unchecked with updateRow method of grid. In this case, beforeValidate, change and check events are fired.

Following methods are also available in Group() and Tree() objects in case of hierarchy checkboxes.

• dataIndx
  Type: String
  field name of column which displays the checkbox UI.

Code examples:

Invoke the method:

Checkbox.checkAll();

Following methods can be invoked on the columns instance. gcm and cm are used in the API. Both are arrays, gcm is the whole colModel that includes parent grouped columns while cm is colModel fragment array, normally used for children columns.

• This method does not accept any arguments.

Code examples:

Invoke the method:

            //collapse the column having known title.
            Cols.alter(function(){

                    return (column.title=="Revenues ($ millions)");
                }).collapsible = {on: true};
            })
        

Accepts or commits the add, edit and delete operations done after turning on tracking.

type limits the commit operation. Possible values are add, update or delete.

rows parameter further limits the type of commit operation to the matching rows only. The format of rows is similar to dataModel.data i.e., an array of row objects and usually fetched from remote server.

When type = add and rows argument is passed, commit updates the primary key i.e., recIndx of the matching records in grid from rows.

• type
  Type: String
  Optional parameter to limit or control the type of rollback.
• rows
  Type: Array
  Optional parameter. An array of rows to limit the type of commit to matching rows only. It acts as a helper while updating primary keys of added records from server. It also helps to control the updated and deleted records from server.

Code examples:

Invoke the method:

//commit all added, updated and deleted records.
grid.commit();

//commit all updated records.
grid.commit( { type: 'update' } );

//commit updated records with matching rows only.
grid.commit( { type: 'update', rows: rows } );

//commit added records only and update the primary key of added records from rows.
grid.commit( { type: 'add', rows: rows } );

It copies selected cells / rows within the grid or from one grid to another.

Code examples:

Invoke the method:

//copy selections.
grid.copy( );

Store or access arbitrary data ( i.e., array, object, string, etc ) associated with a specified row or cell. It acts as a private or meta data store of a cell or row and is different from normal pqgrid row ( i.e., rowData ) and cell data ( i.e., rowData[ dataIndx ]). This method returns the entire data of cell or row when data argument is not passed to it and returns partial data when key name of data is passed to it. Either rowData or rowIndx can be passed to this method. Meta data associated with this API can also be stored or manipulated as part of pqgrid JSON data ( i.e., dataModel.data ) as rowData[ 'pq_rowdata' ] or rowData[ 'pq_celldata' ][ dataIndx ] which can be used by client or remote server.

• rowData
  Type: Object or Array
  Reference to 1-dimensional array or object representing row data.
• rowIndx
  Type: Integer
  Zero based index of the row.
• dataIndx
  Type: Integer or String

Code examples:

Invoke the method:

//Add meta data to a row.
grid.data( {rowIndx: 2, data: { key1: value1, key2: value2 } );

//get whole meta data of 3rd row.
var data = grid.data({rowIndx: 2} ).data;

//get partial meta data of 3rd row with key name 'key1'.
var value1 = grid.data({rowIndx: 2, data: 'key1'} ).data;

//Add meta data to a cell
grid.data( {rowIndx: 2, dataIndx: 'profits',
            data: { 'a': {'b': true} }
        });

Code examples:

Invoke the method:

//Delete 2 nodes from grid
grid.deleteNodes([node1, node2]);

Deletes a single or multiple rows from the local data at provided rowIndx.
The tracking of this operation for commit and rollback is determined by global trackModel.on option unless overridden by track parameter passed to this method.
If source parameter is passed, its value is available in the change event instead of default 'delete' value when a row is deleted by this method.
If history parameter is passed, this operation is added to history or not depending upon value of this parameter.
By default the view is refreshed by this method which can be prevented by passing refresh parameter as false to this method.

Saves the currently edited cell. It's internally used by the grid whenever the cell is saved during inline editing. It participates in tracking for commit and rollback when tracking is on. It can be useful to invoke in custom editors. It fires two events i.e., cellBeforeSave and cellSave. It aborts the save operation and returns false if cellBeforeSave returns false. cellSave event is not fired when save operation is unsuccessful. It fires cellSave event and returns true when save operation is successful. It returns null if no cell is being edited.

• This method does not accept any arguments.

Code examples:

Invoke the method:

//saves the edited cell
var success = grid.saveEditCell( );

Saves the current state of grid as string in browser local storage (default) and returns the state as string.
