[RESOLVED] Enable a button on Custom Ribbon from VSTO

Hi,

I have a VSTO Excel application and I have created a custom ribbon.
This is applied as below.

Code:

---

  public partial class ThisWorkbook
    {
            protected override Microsoft.Office.Core.IRibbonExtensibility CreateRibbonExtensibilityObject()
        {
            return new ReportsRibbon();
        }
        private void ThisWorkbook_Startup(object sender, System.EventArgs e)
        {

            try
            {

---

However from my workbook I want to be able to set one of the buttons as enabled or disabled. How do I access these properties?

It looks from this that I should be able to get the enabled property, although I dont know how to pass it the control but I can see nothing about setting the enabled property.

I came across these two great articles which helped a lot.

however
in VSTO c# the callback is like below

Code:

---

  public bool Audience_getEnabled(Office.IRibbonControl control)
        {       
            return g_blnEnabled;
        }
