ComboBox remains selected after databind

[Dirk Meusel]

I use several Comboboxes on my Windows Forms that are programmed with
VB.NET and VS 2002. For reasons of convenience, the Comboboxes are
filled by databinding them to a dataset. Everything works fine, except
that all Comboboxes are by default marked (or better: the text shown
is selected). Only after clicking once into each Combobox, they appear
in the usual way unselected or unmarked. Its kind of nothing much
important, but when i open a winform with 10 Comboboxes in it, it
looks quite confusing to all of them marked.

So, how can I get the Comboboxes appearing unmarked after they are
bound to a dataset???

I already tried Refreshing the form after databinding as well as
setting the focus to each of the Comboboxes. Neither of these worked.
Any suggestions???

Thanks all!

Dirk,

Probably is it solved when you set the selectedindex two times to -1

It is a known bug.

Thanks Cor, for your reply, but it does not work either. I tried it
the following way in every combination within the FormLoad Event as
well as after the Oleadapter fills the dataset (which is in a separat
function).

Me.cmb1.SelectedIndex = -1
Me.cmb1.SelectedIndex = -1
Me.cmb2.SelectedIndex = -1
Me.cmb2.SelectedIndex = -1

Any more suggestions?

Do it after all databinding

Thanks Cor, for your reply, but it does not work either. I tried it
the following way in every combination within the FormLoad Event as
well as after the Oleadapter fills the dataset (which is in a separat
function).

Me.cmb1.SelectedIndex = -1
Me.cmb1.SelectedIndex = -1
Me.cmb2.SelectedIndex = -1
Me.cmb2.SelectedIndex = -1

Any more suggestions?

Hi Peter,

It worked not out as well, even the combination of both does not have
any effect, I tried:

me.cmb1.SelectionLength = 0
me.cmb2.Selectionlength = 0

as well as:

Me.cmb1.SelectedIndex = -1
Me.cmb1.SelectedIndex = -1
Me.cmb2.SelectedIndex = -1
Me.cmb2.SelectedIndex = -1
me.cmb1.SelectionLength = 0
me.cmb2.Selectionlength = 0

thanks, Dirk
