As many Ext components inherit from Ext.Panel this can function as a catch-all renderer. Internally, Ext.ux.Printer examines the xtype chain of the component you pass it to print, and uses the first renderer that matches. Notice that we registered this renderer for all components with the xtype of ‘panel’. Whatever this function returns is rendered inside the tag of the newly-opened printing window. We subclassed Ext.ux.Printer.BaseRenderer, and in this case all we needed to do was provide an implementation for generateBody. This is probably the simplest print renderer of all – we’re simply grabbing the HTML from inside a the panel’s body and returning it inside our own div. * ', ) Įxt.ux.Printer.registerRenderer('panel', Ext.ux.Printer.PanelRenderer)

Var editor = new Ext.ux.grid.RowEditor() You also need to define what type of Editor is available (if any) on each column: RowEditor is a normal grid plugin, so you’ll need to instantiate it and add to your grid’s ‘plugins’ property. css files on your page and you should be ready to go. This needs to go with your other stylesheets, usually in a directory called ‘css’:ĭownload these two images and put them into your existing ‘images’ folder (the same place the other ExtJS images live): Grab the plugin JS file below and put it where you usually put your. If you still have the ExtJS SDK around you can find these in the examples folder, if not you can get each file as follows: You’ll need to get a copy of the javascript, css and images from the server.

In this fashion we can provide full CRUD for simple models in a single page. This neatly solves the problem of adding a new row to an editor grid, entering data into the first field and finding it save itself straight away, which is rarely desired. It works a lot like a normal Grid Editor, except you can edit several fields on a given row at once before saving. The RowEditor plugin was recently added to the ExtJS examples page.

How to handle event for a extjs component? using listeners config object. For ex for grid events : listeners: {rowclick: gridRowClickHandler,rowdblclick: gridRowDoubleClickHandler} using addListener( String eventName, Function handler, , ) : void Appends an event handler to this component using on( String eventName, Function handler, , ) : void Appends an event handler to this element (shorthand for addListener) For ex: store.on( “datachanged”, function( store ){ ….. }); 21. How to find no of records in a store? using store.getCount() : Gets the number of cached records. store.getTotalCount() : Gets the total number of records in the dataset as returned by the server. 22. How to handle exception while loading datastore? using loadexception event. syntax: store.loadexception() : Fires if an exception occurs in the Proxy during loading. use beforeload : ( Store this, Object options ) : Fires before a request is made for a new data object. If the beforeload handler returns false the load action will be canceled. syntax: store.on(‘loadexception’, function(event, options, response, error) { alert(“Handling the error”); event.stopEvent(); }); 23. how to handle updates for store changes? use store.commitChanges() 24. what is the purpose of each() in store? Calls the specified function for each of the Records in the cache each( Function fn, ) 25. how to get modified records using store object? store.getModifiedRecords() : Gets all records modified since the last commit. 26. how to get record using index? store.getAt( Number index ) : Get the Record at the specified index. 27. how to get record using id? store.getById( String id ) : Get the Record with the specified id. 28. what is the purpose of load() in store? store.load() : returns boolean Loads the Record cache from the configured Proxy using the configured Reader. For remote data sources, loading is asynchronous, and this call will return before the new data has been loaded. store.load({callback: fnCheckData, scope: this}); 29. what is purpose of loadData() in store? store.loadData( Object data, ) : void Loads data from a passed data block and fires the load event. loadData(storeData,false); False to replace the existing records cache. loadData(storeData,true) : True to append the new Records rather than replace the existing cache. 30. How many types of layout managers exist in extjs?what are they? Layouts fall under this package Ext.layout.* Types of layouts: Absolute Layout: This is a simple layout style that allows you to position items within a container using CSS-style absolute positioning via XY coordinates. Accordion Layout: Displays one panel at a time in a stacked layout. No special config properties are required other than the layout. All panels added to the container will be converted to accordion panels. AnchorLayout: This type of layout is most commonly seen within FormPanels (or any container with a FormLayout) where fields are sized relative to the container without hard-coding their dimensions. BorderLayout: Border layouts can be nested with just about any level of complexity that you might need. Every border layout must at least have a center region. All other regions are optional. CardLayout (TabPanel): The TabPanel component is an excellent example of a sophisticated card layout. Each tab is just a panel managed by the card layout such that only one is visible at a time CardLayout (Wizard): You can use a CardLayout to create your own custom wizard-style screen. FitLayout: A very simple layout that simply fills the container with a single panel. FormLayout: FormLayout has specific logic to deal with form fields, labels, etc.FormLayout in a standard panel, ColumnLayout: This is a useful layout style when you need multiple columns that can have varying content height.Any fixed-width column widths are calculated first, then any percentage-width columns specified using the columnWidth config TableLayout: Outputs a standard HTML table as the layout container.you want to allow the contents to flow naturally based on standard browser table layout rules. data, plus manip 31. How we can apply pagination in grid panel ? using Ext.PagingToolbar plugin, we can implement pagination to a grid panel syntax: new Ext.PagingToolbar({ pageSize: 25, store: store, displayInfo: true, displayMsg: ‘Displaying topics {0} – {1} of {2}’, emptyMsg: “No topics to display”, }) // trigger the data store load store.load({params:{start:0, limit:25}}); 32. what is xtype? The xtype will be looked up at render time up to determine what type of child Component like TextField, NumberField etc to create. i,e xtype = Class ———————- button = Ext.Button textfield = Ext.form.TextField radio – Ext.form.Radio grid = Ext.grid.GridPanel combo = Ext.form.Combobox toolbar = Ext.Toolbar 33. what is vtype?

Javascript is an awesome language. It’s super flexible.Browsers are the modern UI paradigm. The javascript Libraries now must provide a rich set of UI Widgets. javascript libraries: JQuery Qooxdoo Dojo Prototype.js mootools extjs 35.how to get record object from store: var record = grid.getStore().getAt(rowIndex); 36. purpose of Load mask? To apply mask to page level / component level. restrict user not to access any components in page var pageProcessBox = new Ext.LoadMask( Ext.getBody(), { msg: ‘Loading Employee details.’ } ); pageProcessBox.show(); 37. purpose of renderer in grid panel? using config option, renderer: fnCellColor where fnCellColor is method to apply color to a cell. 38. how to get selection model used in a grid panel? using grid.getSelectionModel(); method 39. how to stop editing a record? newRecord.endEdit(); 40. how to start editing a record? newRecord.beginEdit(); 41. how to commit a record modification? newRecord.commit(); 42. what is use of combo select event function?

Extjs Vs jQuery: ExtJs and JQuery are kind of apples and oranges. You can compare Ext Core to JQuery, and ExtJs to JQuery UI. Ext JS is a full-fledged widget library while jQuery (not jQuery UI) and Mootools are JavaScript frameworks that help with DOM manipulation etc. Whilst jQuery and Mootools help with the general workings of a site. jQuery UI is a much less rich set of components.
