View Full Version : Enable/Disable buttons if datagrid item selected

29 May 2013, 9:42 AM
What I'm trying to do is enable/disable a set of buttons depending on whether something in my datagrid is selected.

Currently I have a listener listening for the 'select' event on my datagrid, which calls a function and sets my curSelectedDemo varaiable.

I'm coming from Flex, so binding this all together used to be very simple. What is the easiest way to make this happen?

create a controller, find the component, then disable on the fired event.

hi, i just paste a short code example. you can add a listener to your selectionModell and enable/disable some buttons. (you have to set button1 and button2 ...)

selModel: {
xtype: 'rowmodel',
listeners: {
selectionchange: function(sm, selections) {
button1.setDisabled(selections.length === 0);
button2.setDisabled(selections.length === 0);
