Exjts4: How to set a column in a GridPanel dynamically to hidden

Question

in my GridPanel I have different Columns. Now I want dynamically set a few of them to hidden:true. I gave the columns ID's but I have no success on it. For example

Ext.getCmp("mainfield").setHidden(true);

Doesn't work. Any ides or help? THANK YOU!!!

Answer 1

Try this:

grid.columns[columnIndex].hide();

or

grid.columns[columnIndex].setVisible(false);

To find column by id use down:

grid.down('gridcolumn#mainfield').hide();
