[leglubert]

if I want to fill out the "DropDownItems" collection at run time

ok no problem ... but

the DropDownShowing is not raised, if it does not contain at least one element added a time design

Create the DropDownShowing event:

public Form1()
{
    InitializeComponent();
    ribbonButton1.DropDownShowing += RibbonButton1_DropDownShowing;
}

private void RibbonButton1_DropDownShowing(object sender, EventArgs e)
{
    // Do something
}

Here is a sample:

Sorry, but we are misunderstood.

the event exists!

but is not raised if the ribbonButton does not contain at least 1 item in the collection

not practical when you want to create the collection at the runtime:-)

Solution;

• Create an element in collection at design-time
• Delete this item from the collection at run-time
• Add my items to the collection

If the RibbonButton.DropDownItems is empty, the event will not be raised.
If total items in RibbonButton.DropDownItems is >= 1
The event will be raised.
Tested in runtime.
