EXtjs 3.2 :How do I Set the specific cell as uneditable or read only?

Question

I am working with Extjs 3.2 ,my Editor grid consist of 5 column, 4 editable fields and 1 checkbox,

The requirement is that when i uncheck the checkbox, the other four Cells of that row must become readonly.

I am getting the Checked rowIndex ,columnIndex by using Cellclick event, but how do I select that Cell and set the property to Readonly/UnEditable. I have tried using

    gridItems.setEditable(rowIndex, editable);

    gridItems[rowIndex].set('editable', true);

But it is not working.

I am really not getting the reason why this isn't working, do you have any ideas on what I could do differently?

Answer 1

Try this to set the readonly attribute for your checkbox

Ext.getCmp('id').setReadOnly(true);
