ComboBox.Dropdown方法仅显示一个列表项

Question

I'm using a ComboBox in excel (vba) that adds items to the list based on what is typed (near matches) so that if what they are typing already exists in the data range, they can see it and click.

This is all working fine except for the method ComboBox1.DropDown, which is supposed to display the list. Unfortunately it only shows one item with the scroll buttons. Clicking the drop down button or pressing f4 shows the correct number of lines determined by the box's properties.

I've searched and searched, any clue how to show all items in the list automatically?

This is my first question on SO, please advise if tagged incorectly.

edit: ActiveX control, .listRows and .listFillRange do not seem to help

Answer 1

I've been calling .DropDown in a custom Sub that creates the list, I needed to change it so it is now the last line in ComboBox1_Change().

Not sure why it acts differently in _change() than it did in my Sub (that was called by _change())!

I think that this is actually related to using the .clear method and then calling .Dropdown, it doesn't recalculate how many lines to show. I may need to just keep them in separate Subs Thanks for your responses @PatricK

Edit: Not solved, it now works correctly with the first "change" more letters typed causes the rest of the list to stay un-cleared while the first row is updated and has the scroll buttons. I wish I knew exactly how these methods are written and when they get executed.

Answer 2

ComboBox1.Visible = False
ComboBox1.Visible = True
ComboBox1.Activate
If ComboBox1.ListCount > 0 Then
   ComboBox1.DropDown
End If

This code seems to do the trick, at least more than one line is diplayed, and the list is becomes shorter if items are removed, unlike before.
