How to clear combobox?

[feng]

In our VB.Net Windows form application we have a combobox
pre-populated with a list of items. What I need is simply
clear everything from it's dropdown, when a button is
clicked. I tried everything I can think of, such as set
data source to nothing, etc., but still not been able to
make it happen.

Can someone show me how to do it?

Thanks

Is it a data control?

If not, then call ComboBox1.Items.Clear

Are you using a databound control?

Try that:

\\\
Me.ComboBox1.Items.Clear()
///

Thanks for your reply.
The Comobox1.item.clear doesn't seem to work properly
since have datasource set - I am getting an error message
about this. When I try to set Comobox1.DataSource =
Nothing then I can clear the list, but I still have one
line displyed in the combo: System.Data.DataRowView. What
should I do with this?

Thanks

You have to set the data source = nothing
before issuing ..items.clear

Have you tried calling DataTable.Clear on the table that it's bound to?
