Hide column doesn't work

[EBS]

Bonjour,

How to hide columns dynamically ?

this code doesn't work

var cols = grid.columns;
cols.each(function(column){
     column.hide();
}

==> Error : column.hide is not a function
In API doc, the function hide() exists for column.


this code has no error but the columns are still visible

var cols = grid.columns;
cols.each(function(column){
          column.hidden = true;
}

EBS,

Can you try:

var cols = grid.columns;
cols.each(function(column){
          column.setVisible(false);
}

Error : column.setVisible is not a function

EBS,

Just noticed the issue:

You need to use forEach, not each. See below:

var cols = grid.columns;
cols.forEach(function(column){
          column.hide();
}

each works too (Ext.Array.each);
but not the function hide()

[karnak]

very strange... All works fine for me with the code I posted and all of my grid columns disappear.

perhaps because my grid is in a tabpanel...i'll try without tabpanel

I found the problem and I think it is a bug.

if at least one column of the grid has the property "locked: true", I have an error "Error : column.hide is not a function"
I feel that setting this property, the object is no longer considered a column because all methods cause an error (getindex (), hide (), show (), etc ...)

Example:
with the property "locked: true" for the column "Total", an error occurs (getIndex is not a function);
without this property, the columns '01' and '02' aren't visible (OK)

var myData = [
    ['1', 'Player1', 10, 20, 15, 45],
    ['2', 'Player2', 20, 10, 10, 40],
    ['3', 'Player3', 30, 10, 30, 70],
    ['4', 'Player4', 10, 30, 25, 65]
];
Ext.regModel('cm', {
        fields: [
        {name: 'idJoueur', mapping: 'idJoueur'},
        {name: 'joueur', mapping: 'joueur'},
        {name: 'J01', mapping: 'J01'},
        {name: 'J02', mapping: 'J02'},
        {name: 'J03', mapping: 'J03'},
        {name: 'total', mapping: 'total'}
        ]
});
var store = new Ext.data.Store({
    model: 'cm',
    data: myData
});
var grid = new Ext.grid.GridPanel({
    title : 'TEST',
    store: store,
    columnLines: true,
    columns: [
        { header: "Joueur", dataIndex: 'joueur',width: 150, menuDisabled:true, sortable:false,draggable:false,fixed:true},
        { header: "01", dataIndex: 'J01',width: 45, align: 'right', menuDisabled:true, sortable:false,draggable:false,fixed:true},
        { header: "02", dataIndex: 'J02',width: 45, align: 'right', menuDisabled:true, sortable:false,draggable:false,fixed:true},
        { header: "03", dataIndex: 'J03',width: 45, align: 'right', menuDisabled:true, sortable:false,draggable:false,fixed:true},
        { header: "Total", dataIndex: 'total',width: 60, align: 'right', locked:true,menuDisabled:true, sortable:false,draggable:false,fixed:true}
    ],
    id: 'result',
    border:true,
    height:548,
    renderTo: 'affichagePage',
    listeners:{
        afterrender: function(grid){
            var cols = grid.columns;
            cols.forEach(function(column){
                var indexCol = column.getIndex();
                if(indexCol == 1 || indexCol == 2){
                    column.hide();
                }
            });        
        }
    }
});

This bug is still present on 4.0.2-rc3

[joelchu]

same problem here but a little bit different error.

I tried - column.hide() - then throw an exception "empty object has no method getWidth() (29620 in the ext-with-comment.js

it just oneliner this.el.getWidth() ...

Try setVisible - gone down two loop then hit the same problem.

Have to add - my grid is a tree grid panel (with no lock configuration) anyone got a solution? Thanks.

UPDATE

To hide the column - I did

column.hidden = true; 

and it works (disappear). Also able to set the header text

column.setText(new text); 

but everything to do with width are f**k ... can not do hide(), setVisible(), setWidth()

The last one was problematic - after showing hidden column or hide them, I want to able to refit all the columns. But now I couldn't set the width - some column got push over of the view ...

did you file this as bug report?
