• field – The identity of the field in a row of data that should be shown in cell.

• name – The column name of the column

• decorator – A function that takes (data, row.id, row.visualIndex) as parameters and

returns the content of the cell. If not supplied, the data of the cell itself is returned.

• editor – The class name of the Dijit widget to show for editing

• editorArgs –

• width – The width of the column in CSS units

• editable – whether or not the cell is editable

If we need to change the structure after the grid has been created, we can call the setColumns()

method which takes an array of column objects as a parameter.

Within the GridX package, there is an object called "Row" that owns a row in the grid. This can be

returned by a "model.byId()" function call.

Within the Row there are some important functions:

• getData() - Get the grid data of this row.

• getItem() - Get the store item of this row.

Notes:

• If we use GridX inside a custom widget, do not "startup" GridX until the startup of the

enclosing widget itself. If we start it too early, it doesn't seem to remove the "No Data"

overlay.

• We can replace the data associated with a Grid using the "setStore()" method found on the

grid.

GridX Width and Height

The width and height of the grid should be supplied. Setting the property called "autoWidth" to

"true" results in the width of the grid being calculated from the width of the columns.

There is also a property called "autoHeight". If set to true, then the grid will always show all of

its content.

The grid also provides paging support via the modules called "gridx/modules/Pagination"

and "gridx/modules/pagination/PaginationBar".

GridX - Adding and removing rows

A new row can be added into the Grid by accessing the store object and invoking the add method.

We can delete a row using the store associated with the grid.

grid.store.remove(row.id);
