Difficulty with hidecolumn

[Thiago]

Hello,

I don't have much knowledge with JavaScript, I'm not able to hide columns with the hidecolumn.

My code is very similar to this

I would also like to add a column to this example static text.

Thanks

I did it, the problem is that I was writing the wrong column name.

My Error

taskFields: {

      id: 'TaskID',

      name: 'TaskName',

},

columns: [

     { field: 'taskid', visible: false},

],

Thanks

Hi Thiago, 

Absolutely, defining the wrong field name in the columns property was the problem in hiding the ‘TaskID’ column in load time. We can also dynamically hide and show the column using hideColumn and showColumn public method  respectively. 

Please find the below code example. 

<button id="hide">Hide</button> 

  document.getElementById('hide').addEventListener('click', function () { 

     ganttChart.hideColumn('TaskID', 'field'); 

});
