I want to set focus on black field in each tab sequentially,

suppose I am on Tab 1 and click on button its take me to Tab 3 with focus on Field 3 if this field is blank.

Hi @matrixwebtech,

So, the task #1 is to determine what TextField is to going to be focused.

Using this code you can determine the field is empty or not.

Ext.isEmpty(App.TextFied1.getValue());

Then you should activate the tab with that field. I would try this code:

textFieldToFocus.up("tabpanel").setActiveTab(textFieldToFocus.up("panel"));

Then you could finally focus the field:

textFieldToFocus.focus();

I have not tested it. So, you might need to correct something.
