问题 EditorGridPanel shows a small red triangular corner on the column that is edited to indicate an unsaved record. Since I am using autoSave, I don't need to indicate the record as dirty/unsaved. Is there an easy way to disable this ? 回答1: See this : http://www.sencha.com/learn/Ext_FAQ_Grid#Dirty_Record_.2F_Red_Flag_.28modifying.2C_etc..29 回答2: view: Ext.grid.GridView({markDirty: false}) or viewConfig: { markDirty: false } 回答3: .x-grid3-dirty-cell { background-image: none; } 来源： https:/

May I know what mistakes did i make? function searchTerms(){ var searchGrid = new Ext.grid.GridPanel({ }); var searchPanel = new Ext.form.FormPanel({ region: 'south', height:150, items:[ { xtype: 'textfield', fieldLabel: 'Keywords', },{ xtype: 'textfield',

问题 I make an ExtJS AJAX request and I want the standard browser 'save as' dialog box to be displayed to the user. The file to download can be a pdf, jpg or png file. At the moment the AJAX request is successfully submitted but as it's asynchronous no dialog box comes up. I could simply not use AJAX but there is a lot of javascript code that I need to use prior to making the request and I don't really feel rewriting it to java. My code looks like this: var params = getPrintInfo(form); Ext.Ajax

The store has a listener on the load event, which selects row 8 of the grid's selection model and tries to bring it into focus. In Chrome (currently version 33) this works and the specified record is visible. In IE (version 11) this does not work. At the time of the alert('pause'); statement, the grid is visible with the specified row visible. But after clicking away the alert message, the
