I have a situation where I have an amount text box and then Pay now button beneath it. When I enter the amount, the pay now button should be enabled and then the next step is to click on it. This is an automated script in Jscript. When I do manually, as soon as I enter the text, the pay button does get enabled. But when my automated script runs, it does settext in the textbox but then the button is still disabled. So the next event of clicking on it fails with the exception that the button is disabled. I tried to enable it but seems like I need to have an event handler for this. Do I write the event handler when the textbox has been filled in. Or may be in tab out from that textbox. Please help me to find the right approach.
