this will mimic as if a double_click was issued: (one could use the 'Stopwatch' as well)

Private Sub ComboBox1_MouseClick(ByVal sender As Object, ByVal e As _ System.Windows.Forms.MouseEventArgs) Handles ComboBox1.MouseClick

Static prevClick As DateTime = DateTime.Now

'as mousedoubleclick doesn't work, detect 2 clicks within a defined time-laps to mimic

'here use 500 millisecondsbetween clicks
If DateTime.Now.AddMilliseconds(-500) < prevClick Then

'do what you expect the double_click to do
'....

End If

'set the reference for the next click
prevClick = DateTime.Now

End Sub

Hi Kira,

This is a rediculous situation! People were complaining about this not working back in VS2005.

Now, using VS2008, I find the problem *still* exists. Even worse, SP1 has not fixed this problem either!

This isan unbelievable oversight, & I am at a complete loss as to why 3 versions later this problem still hasn't been addressed.

It's not like it's some weird kind of thing that very few people will want to do, it's a fundamental event that it seems *all* windows forms controls can handle, *except* the combobox.

It's not good enough!

I'm using C# in VS2008.
A very important point, that I have worked out by trial and error, is that a ComboBox's MouseDoubleClick eventnever gets through to a user event handler.
The MouseClick event usage described by "dibidibi" only works if the ComboBox has a DropDownStyle property of "DropDown" (at least it certainly doesn't work if the DropDownStyle is "DropDownList"), and I found that the only practical way to get it to work is if you double-click in the "edit box", not in the dropped-down list - you can also setthe "AutoCompleteMode" to "SuggestAppend" with AutoCompleteSource set to "ListItems" if that suits your needs.
