This is regarding setting focus to a combobox. If you open the mxml in a browser and click on the go button, you get an alert message. Now acknowledge the alert by pressing the space bar. The focus does not go to the combo box i.e. clicking the down arrow does nothing. Click on the go button again. Now acknowledge the alert message by clicking on the ok button. Now press the down arrow and you find that the combobox gets the select event and you can see the values changing. Why is there a difference in behaviour depending on how we acknowledge the alert message Note: we are able to set focus to the combobox if we generate the alert message from flex but are unable to set focus to combobox if the alert message is generated from a javascript function, which is invoked on clicking a button. Another observation: we unable to set focus to a textinput if the alert message is being generated from a javascript function. Our existing application has numerous instances of alert messages being generated from javascript functions. So changing all these to alert messages from flex may not be acceptable Your inputs please Srikanth -----Original Message----- From: Abdul Qabiz [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 08, 2005 1:33 PM To: flexcoders@yahoogroups.com Subject: RE: [flexcoders] couple of things needed for dropdown Hi Srikanth, I will look into this issue, I will confirm the same later in evening.

Scenario: Click on save button and you find that there is a validation error which needs the user to make a/another > choice on the dropdown. The focus should get set to the dropdown. Setting the focus on ComboBox while mouse is still over Button, would be hard. But there is a better of doing validation, you can use Validator to show error messages. If user has selected a wrong option, ComboxBox's border would turn read and doing a mouse-hover would reveal a error message. See the example code below. > 2.Need facility to be able to scroll through the list of values in a dropdown using the roller button on a mouse. This does not seem to happen for a dropdown created > using Flex You mean Scroll Wheel in Mouse. It does work, did you test in browser? it works on Firefox as well as IE. ###test.mxml### <?xml version="1.0"?> <mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml"; creationComplete="onAppInit()" > <mx:Script> <![CDATA[ var countries; function onAppInit() { countries = ["India", "Pakistan", "Sri Lanka", "Indonesia", "Singapore", "USA", "UAE"]; } function validateCountry(validator, value) { if (value == "Pakistan" || value == "Indonesia") { validator.validationError("Wrong Country", "This country is not supported country list.", "country"); } } ]]> </mx:Script> <mx:Model id="membership"> <country>{countryNames_cb.value}</country> </mx:Model> <mx:Form id="membershipForm"> <mx:FormItem id="countryNamesItem" label="Countries"> <mx:ComboBox id="countryNames_cb" dataProvider="{countries}"/> </mx:FormItem> </mx:Form> <mx:Validator field="membership.country" listener="countryNames_cb" validate="validateCountry(event.validator, event.value);"/> </mx:Application> HTH, -abdul Yahoo!
