How to hide gridpanel columns ?

[Vikram]

I tried with to hide columns as below:

Ext.ComponentQuery.query('#email')[0].show();

or

gridPanel.columns[14].show();

but hiding one column its working fine but in case of multiple columns more than 3 its hanged and sometimes have to kill the page ...

any suggestion and help would be appreciated.

Thanks & Regards

It would help to see your code. The call should not break unless you are trying to access a bad column.

You can also use reconfigure if you have a lot of columns:

If you're hiding multiple columns at once you should suspend layouts:

Ext.suspendLayouts();

// Hide columns

Ext.resumeLayouts(true);

I'm not sure this will help if it's hanging but it should improve performance.

Hello skirtle,

thanks for reply but your below approach did't work for me.

Ext.suspendLayouts();  // Hide columns  Ext.resumeLayouts(true);

As mentioned, you would need to show your code.
