Hello Sanjay,

What Excel build are you using? What Add-in Express build are you using?

Hello Sanjay,

Are you saying that calling adxExcelTaskPanesCollectionItem1.TaskPaneInstance in the Click event of a Ribbon button produces a wrong pane? Do you activate books/windows while you run that code?

Hello Sanjay,

The issue is this code line:

adxRibbonButton1.Enabled = !TaskPane.Visible;


It disables Ribbon control instances in *all* Excel windows. Office reacts to this command in the active window; when you activate the second window, Excel handles it as well.

The way out of this is writing code handling the PropertyChanging event of the Ribbon button component. In that event, you write this IF statement

if (e.PropertyType = ADXRibbonControlPropertyType.Enabled) {}


And, if the condition is true, retrieve the context object, cast it to Excel.Window, if this window contains a pane, set e.Value = true; otherwise, e.Value = false. Whatever you, whatever exceptions you get, you should release the context object since it is a COM object and you should release every COM object created by your code.
