I would like to create a custom button for the toolbar and have it perform a postback when it is clicked.  I assumed that it would be simply a matter of adding the postback="True" property to the tag representing my custom button to my custom ".config" file.

Unfortunately it doesn't seem to work ... is there any other codes that I should be adding to force the postback??  he button appears on my toolbar and the Confirm javascript function I added seems to work fine, but not postback is invoked.

 

Any help is appreciated.
