Populating Array Grid with one column hidden

[rahulmca1@gmail.com]

Hi,

I am using Array Grid and populating grid form an array. But I wanted to know

1. Can I Populate grid with columns id, name,salary using Array Grid so that in the grid id column remains hidden and is represents the row id of grid
with array

    var myData = [
			[1,'John',5000],
                        [2,'Petric',8000]
                        ]

just like what we do in dase of ajax xml grid using

    var schema = {
            tagName: 'Item',
            id: 'ASIN',
            fields: ['Author', 'Title', 'Manufacturer', 'ProductGroup']
        };

Can I use arrays in this case to populate grid.

myDataModel = new YAHOO.ext.grid.DefaultDataModel([
      [1,'john',5009],
      [2,'peter',8000]]);

var cols = [
        {header: "Id"},
        {header: "Name"},
        {header: "Salary"}];

myColModel = new YAHOO.ext.grid.DefaultColumnModel(cols);
myColModel.setHidden(0);
myGrid = new YAHOO.ext.grid.Grid('div-of-my-grid', myDataModel, myColModel);

At least I think this is what you're looking for

Hi,

Thanks for replying.

I tried to use

myColModel.setHidden(0);

to hide my column but it did not worked but when I tried

myColModel.setHidden(0,true);

It works fine where as in documentation we do not have any such method
docs say

public function setHidden(Number colIndex)
Sets if a column is hidden.

Thanks

You can specify hidden in your columnModel

{header:id, hidden:true}

actually im using setHidden(0,true) myself, and it was used in my original reply in this thread. but i went back a couple of hours later and changed it to setHidden(0) because thats what it says in the docs (i didnt want to spread faulty code blabla)

this is from DefaultColumnModel.js:

    /**
     * Sets if a column is hidden.
     * @param {Number} colIndex The column index
     */
    setHidden : function(colIndex, hidden){
        this.config[colIndex].hidden = hidden;
        this.totalWidth = null;
        this.fireHiddenChange(colIndex, hidden);
    },

once again we prove that code > docs

I would say that you were right to begin with. The docs are wrong. The correct usage is
setHidden(0, true) or setHidden(0, false) to hide or show the column. However, note that calling this method fires the hiddenchange event. You may or may not have this event hooked, but if you do, it may not be correct to fire it when you are initially building the columnModel.

If you're making a column hidden initially, e.g. when you're creating the CM, the way to do it is in the config with

{header:id, hidden:true}

This way you don't fire an event that may have unintended consequences.
