Add Collection to Combo Box

Hello,
I have built a test ribbon with a combobox and I would like to add a custom collect of items to choose from. Specifically, I would like to display the open workbooks to choose from. I can use the ADX Collection Editor to create a list of items to choose from, but where can I put code to add my own collection without using the ADX Collection Editor.
Thank you!
Jeremy

Hello Jeremy, 

private void adxRibbonButton1_OnClick(object sender, IRibbonControl control, bool pressed) {
    this.adxRibbonComboBox1.Items.Clear();
    Excel.Workbooks wbks = ExcelApp.Workbooks;
    Excel.Workbook wbk = null;
    for (int i = 1; i <= wbks.Count; i++) {
        wbk = wbks[i];
        AddinExpress.MSO.ADXRibbonItem item = new ADXRibbonItem(this.components);
        this.adxRibbonComboBox1.Items.Add(item);
        item.Caption = wbk.FullName;
        Marshal.ReleaseComObject(wbk);
    }
    Marshal.ReleaseComObject(wbks);
}


I use this code in the Click event of a Ribbon button. You can use it whenever required. If you need to use it in NewWorkbook or WorkbookOpen, I would check if the code lists the workbooks correctly.

Thank you Andrei. I would like to list all open workbooks of all open instances of Excel. In another post you said
A COM add-in should only use the Application object that Office passes to it at startup
Does that mean that a COM add-in cannot get the open workbooks of other open instances of Excel, or is it possible to get all open workbooks?
Thanks!
Jeremy

Hello Jeremy,

I believe you won't be able to start the second Excel instance without using some hack.

Thank you,
Is there an event that I can tie this to so the list of open workbooks is always available to the user? For example, when the Add-In ribbon is selected, or the combobox list button is pushed, the list of open workbooks is automatically generated?

Hello Jeremy,

You need to regenerate the list of workbooks in every Excel event which is triggered when the list of workbooks is changed; check the events provided by the Excel Events component (ADXExcelAppEvents).
