Hello,

I’m trying to create a chevron button on a CExtPropertyGridToolBar, because we added several buttons on this toolbar and when the window is too small, some buttons dissappear. I tried calling the InitContentExpandButton() method after inserting the custom buttons in the toolbar, but the method always return false. How can I do that?

Thanks for your help!

Thanks for your help, it works well now.

The chevron is invisible because the CExtPropertyGridToolBar class implements the following virtual method:

CExtBarContentExpandButton * CExtPropertyGridToolBar::OnCreateBarRightBtn()
{
    __EXT_DEBUG_GRID_ASSERT_VALID( this );
    return NULL;
}

Please override it and invoke the CExtToolControlBar class method.
