Usage

Please include the stylesheet index.css in your project. If you are using webpack with css-loader, you can require it: require('react-datagrid/index.css')

#### NOTE:
For optimal performance, make sure you use react-datagrid with the production version of React, not the dev version. The dev version contains a lot of checks, which slow down grid scrolling/rendering quite a bit.

Of course for development, you can use React dev version, but this is just a warning so you won't be put off if you see some jank in dev mode. It will dissapear when you switch to production (minified) version. We are working on this, to make the datagrid usage experience as optimal as possible even in development.

#### Example
`jsx

var React = require('react')
var DataGrid = require('react-datagrid')

var data = [
{ id: '1', firstName: 'John', lastName: 'Bobson'},
{ id: '2', firstName: 'Bob', lastName: 'Mclaren'}
]
var columns = [
{ name: 'firstName'},
{ name: 'lastName'}
]

`

Props

There are a lot of props that can be configured for the datagrid. We'll try to categorize them so they are easy to follow

#### Basic

* dataSource: Array/String/Function/Promise - for local data, an array of object to render in the grid. For remote data, a string url, or a function that returns a promise.
* idProperty: String - the name of the property where the id is found for each object in the data array
* columns: Array - an array of columns that are going to be rendered in the grid

Each column should have a name property, and optionally a title property. If no title property is specified, a humanized version of the column name will be used.

* name: String
* title: String/ReactElement - a title to show in the header. If not specified, a humanized version of name will be used. Can be a string or anything that React can render, so you can customize it as you please.
* render: Function - if you want custom rendering, specify this property

`jsx
var columns = [
{ name: 'index', render: function(v){return 'Index ' + v} }
]
`

* style: Object - if you want cells in this column to be have a custom style
* textAlign: String - one of 'left', 'right', 'center'

#### Sorting

Sorting the data array is not done by the grid. You can however pass in sort info so the grid renders with sorting icons as needed

* onSortChange: Function(sortInfo)
* sortInfo: Array - an array with sorting information

Example
`jsx
var sortInfo = [{name: 'firstName', dir: 'asc'}]
var sorty = require('sorty')
//sorty is a package which sorts an array on multiple properties

function sort(arr){
return sorty(sortInfo, arr)
}

function onSortChange(info){
sortInfo = info
data = sort(data)
//now refresh the grid
}

var data = [...]

data = sort(data)
sortInfo={sortInfo}
onSortChange={onSortChange}
dataSource={data} idProperty='id' columns={columns} />
`

#### Columns

##### Column styling

Column customization/styling can be done with different properties on the column object:

* style: Object - a style object to be applied to all cells in this column
* textAlign: String - one of 'left', 'right', 'center'
* className: String - a className to be applied to all cells in this column.
* render: Function(value, data, cellProps) - if you want custom rendering, specify this property

`jsx
var columns = [
{ name: 'index', render: function(v){return 'Index ' + v} }
]
`

The column.render function is called with 3 args:

* value - the default value to be rendered (equals to data[column.name])
* data - the corresponding data object for the current row
* cellProps - an object with props for the current cell - has the following properties:
* rowIndex - the index of the row
* index - the index of the column
* style - a style for the cell
* className - a className for the cell

Example:

`jsx
var data = [...]
var columns = [
{
name: 'firstName',
className: 'first-column',
textAlign: 'center',
style: { fontWeight: 'bold' }
},
{
name: 'lastName',
render: function(value){
return
Last name: value

}
]

`

##### Column showing/hiding

When a column is shown/hidden, you can be notified using the onColumnVisibilityChange callback prop.

* onColumnVisibilityChange: Function(column, visibility)

You can specify a column is visible/hidden with the following props on column objects:

* defaultVisible: Boolean
* visible: Boolean - controlled (which means you have to manually set column visibility when it changes, by using onColumnVisibilityChange)

If you prefer to use the "hidden" alternatives, you can use defaultHidden and hidden.

##### Column reordering

If you want to enable column reordering, just specify the onColumnOrderChange prop on the grid:

* onColumnOrderChange: Function(index, dropIndex)

Example
`jsx
function handleColumnOrderChange(index, dropIndex){
var col = columns[index]
columns.splice(index, 1) //delete from index, 1 item
columns.splice(dropIndex, 0, col)
this.setState({})
}


`

#### Styling

* rowStyle: Object/Function - you can specify either a style object to be applied to all rows, or a function. The function is called with (data, props) (so you have access to props.index for example) and is expected to return a style object.

* rowProps: Object - props to be passed to all rows
- rowProps.overClassName - a css class name to be applied when mouse is over the row
- rowProps.selectedClassName
- rowProps.className

* rowFactory: Function - a factory function for rows. It can return undefined if you only want to change the props object passed to the function and rely on the default rendering.


#### Remote data

* dataSource: String/Function/Promise if you specify a url to load remote data from, by default, pagination props are appended to the url as query params (pageSize, skip).

For an example, see examples/restore-grid-state

#### Pagination

When you have remote data, pagination is setup by default. If you want to disable pagination, specify the pagination prop with a false value.

* pagination: Boolean
* defaultPageSize: Number
* pageSize: Number - controlled alternative for defaultPageSize. When pageSize changes, onPageSizeChange(pageSize) is called
* defaultPage: Number
* page: Number - controlled alternative for defaultPage. When page changes, onPageChange(page) is called

Contributing

Use Github issues for feature requests and bug reports.

We actively welcome pull requests.

For setting up & starting the project locally, use:

`sh
$ git clone https://github.com/zippyui/react-datagrid
$ cd react-datagrid
$ npm install
$ npm run dev # or npm run hot
`

Now navigate to localhost:9090

If you want to have react-hot-loader enabled, and see code changes pushed instantly, without losing page state, use npm run hot instead of npm run dev.

Before building a new version, make sure you run

`sh
$ npm run build
`
which compiles the src folder (which contains jsx files) into the lib` folder (only valid EcmaScript 5 files).
