I apologize if this isn't the correct forum, but I'm not exactly sure where this should be posted... I just got Visual Studio 2010 and I'm working on a Custom Outlook Add-In. I'm using the example at to tie a new Ribbon to a Custom Pane (User Control). In the example it has you add a textbox to the pane. It's realatively simple to have the pane populate the Textbox1 with a value using the on_load event of the pane, but if I want to change the textbox value by clicking a button on the Ribbon, how do I access the textbox object to do so (from a ribbon control)? I've tried several different paths (such as Globals.ThisAddIn.TaskPane1.textbox1.text) and intellisense doesn't seem to want to give me the "textbox1.text" property... Most everything I've done to this point has been in VBA, and I know this is going to be a change for me... Any help is greatly appreciated!
