disabling a multifield based on selection

Hi  rush_pawan,

I have three tabs dynamically created with the help of ur your suggestion given above. It works fine.

I have another requirement. If i select one tab amongt the three, there is a drop down list with values and a multifield(textbox). If select a particular value in drop down list the multifield should be diasbled.

It works well for a dialog of xtype dialog.

function(box,value){var ans = box.findParentByType("dialog").form.findField("anstext"); disableAnsText(ans,value);}

function disableAnsText(ans,value)

{

   if(value == "date") {

                    alert("anstype value - "+value);

              ans.setDisabled(true);

    }

}

Now i have 3 tabs in a dialog of xtype tabpanel. How can i achieve the same with the tabpanel.

Thanks. It would be of great help  if i get an answer for this.
