Question

I want to call method in controller from view when click a cell in grid.

{ header: "<img src='/Content/images/icons/page_white_acrobat.png'/>", width: 30, dataIndex: 'documents', sortable: true, renderer: this.hasDocument,
    listeners: {
        click: function () {
        //how to call method in controller?
        }
    }
},

Anybody know, please advice me.

Thanks!

You will have a lot of tutorials for extjs 4 on the official forum of the project by Sencha.

When I provide some usefull link to good starting tutorials… with a specific one’s about grid management… I think people could look at it really before voting down. Look at it and see yourself some very better ways to do what the question asker wants to do.

Providing direct answers are not always the best way to learn.

Anyway… the following will do the trick:

var controller = this.getController(Ext.String.capitalize(config.controller));
/* where config was an argument of your callback method) */

I suggest you to decouple as much as possible View from Controllers and View from Model. If you look at the projects I have linked, you will find in the Viewport.js a good way to do that. It is calling the controller with .callParent(arguments) method call at the end of these short script.
