    Question Ext.grid.CheckColumn is not a constructor

    Ext.grid.CheckColumn is not a constructor


    this code example chowing how to use the CheckColumn plugin seems to work fine, but when I try and replicate it into my code I get:
    Ext.grid.CheckColumn is not a constructor

    I'm going by the edit-grid example in the ext.2.0 examples

    I'm fairly new to javascript so I'm having a bit of trouble debugging this.
    Any pointers would be greatly appreciated. Here's the CheckColumn plug-in in my code

    in fact I get that is not a constructor error on anything that is a plug-in and extends some class, am I missing an include or something?

    Code:
    <script type="text/javascript" charset="utf-8">
        
        var grid_store;
        var selectionModel;
        var otherSelModel;
        var contact_grid;
    
        Ext.grid.CheckColumn = function(config){
            Ext.apply(this, config);
            if(!this.id){
                this.id = Ext.id();
            }
            this.renderer = this.renderer.createDelegate(this);
        };
    
        Ext.grid.CheckColumn.prototype ={
            init : function(grid){
                this.grid = grid;
                this.grid.on('render', function(){
                    var view = this.grid.getView();
                    view.mainBody.on('mousedown', this.onMouseDown, this);
                }, this);
            },
    
            onMouseDown : function(e, t){
                if(t.className && t.className.indexOf('x-grid3-cc-'+this.id) != -1){
                    e.stopEvent();
                    var index = this.grid.getView().findRowIndex(t);
                    var record = this.grid.store.getAt(index);
                    record.set(this.dataIndex, !record.data[this.dataIndex]);
                }
            },
    
            renderer : function(v, p, record){

    I noticed it also, but I figured it out if you define the Ext.grid.CheckColumn before doing something with it you won't get this error.

    Shortly - it is a matter of the position in the file - put it up.

    Include the javascript required for that checkcolumn! Check the examples
    It's not part of the core EXT suite.

    Default Single Cell Selection, Copy Paste in multiple cells in same gird

    Single Cell Selection, Copy Paste in multiple cells in same gird


    Hi,

    Even I have the same requirement

    I want to develop two things in an existing tree grid of our product:
    1. Single Cell Selection instead of rowselection. Copy it using Ctrl + C,
    2. Multi select cells in grid, Paste the copied value using Ctrl + V

    I wanted to know whether this is possible and how.

    Any links or examples on this will be appreciated

    Thanks in advance. Awaiting response
