Model API:
Instead of passing SlickGrid an array of row objects, you can pass an object that holds (and updates!) all your rows. This object, which SlickGrid calls a Model
, only needs to respond to a simple API:
model.getItem(i) // Returns the ith row
model.getLength() // Returns the number of items
Row API
If you modify the nth row, you will need to tell the grid that the row is invalid, and then call render()
to update it:
grid.invalidateRow(n)
grid.render()
You can also call grid.invalidateRows()
to invalidate a lot of rows at once, and, if you just want to re-draw the whole grid, callgrid.invalidate()
(which would do a render()
automatically.)
grid.scrollRowIntoView(rowIndex)
- scroll the grid until a row is visible.
grid.scrollRowIntoView(100)
Column API
grid.getColumnIndex(columnName)
- Returns the numeric index of the given column. Useful when a column index is required by the API.
grid.getColumnIndex('first_name')
Column options:
Booleans
- sortable
- resizable
- rerenderOnResize
- focusable
- selectable
Other
- id A unique identifier for the column within the grid
- name The display text
- field The name of the data object property to pull content from
- cssClass
- headerCssClass
- width
- minWidth
- maxWidth
- toolTip
Grid's Selection API
Get the list of selected grid rows:
grid.getSelectedRows() // returns [0,1] if the first two rows are selected.
Set the rows at the following indexes as selected:
grid.setSelectedRows([0,10])
Cell API
grid.setCellCssStyles(key, hash)
- Sets CSS classes to specific grid cells. key
is name for this set of styles so you can reference it later - to modify it or remove it, for example. hash
is a per-row-index, per-column-name nested hash of CSS classes to apply.
Since all that sounds complicated, and mleibman
can probably explain it better, here is an example. Suppose you have a grid with columns:
["login", "name", "birthday", "age", "likes_icecream", "favorite_cake"]
...and you'd like to highlight the "birthday" and "age" columns for people whose birthday is today, in this case, rows at index 0 and 9. (The first and tenth row in the grid).
.highlight{ background: yellow }
grid.setCellCssStyles("birthday_highlight", {
0: {
birthday: "highlight",
age: "highlight"
},
1: {
birthday: "highlight",
age: "highlight"
}
})
grid.addCellCssStyles(key, hash)
- The add-only sibling to grid.setCellCssStyles(key, hash)
. Will throw an exception if you try to set the same key twice without calling removeCellCssStyles()
. Use setColumnCssStyles()
instead if you don't want that.
grid.removeCellCssStyles(key)
- Removes styles under key
from the grid.
Custom Field Accessor
By default field values are access via item[columnDef.field]
. To have a custom field accessor, overwrite the defaultdataItemColumnValueExtractor
option.
var options = {
dataItemColumnValueExtractor: function(item, colDef) {
return item.get(colDef.id);
}
};
