Events in 2 User Controls.

Here's my situation:

 I have a page ( Index.aspx), here i have 2 place holders and i have two different user controls. call them: uc1 and uc2 ( user control)

 Both these user controls have textboxes, and a submit button.

 Here is what i want to do:

 if uc1 button is clicked, i want to check if uc2 textboxes are filled first and call the submit button of the uc2 control -
 and then do a uc1 button click. I am trying to check if the user has login information in the uc2 control and then do a some button click on the uc1 control.

 the same way - if the user has some text information in the textboxes of uc1 and they click on the uc2 submit button - i want
to first finish uc2 button click and only then do a uc1 button submit.

By the way: there are some bussiness logic in each of these button submits.

 I am trying to combine the two on a page level and process both if some information is entered in either of the controls.

I know this has to be done using some bubbling of events, but dont know how to proceed.

Should i create a separate class to handle this, or just do it on the page..


Gurus, Any help is appreciated.


Thanks in advance.
