How to show list while setting visible=true

Gurus,
One more Question !

How to clear Combobox's selection,
it means... after loading application, combobox dosen't show any value unless selected. Once selected, combobox shows any value all the time.
so how to clear combobox's selected value ??

Thank you all ....

ComboBox.SelectedIndex = -1

It worked great, thank you.

I have one more issue.

I want to set combobox visible=true on clike event.
at the same time I want to show all list[value] of combobox.

what should I do.

Thank you.

this mate?

VB Code:

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
      ComboBox1.SelectedIndex = -1
      ComboBox1.Visible = False
   End Sub
 
   Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
      Dim s, s2 As String
      For Each s In ComboBox1.Items
         s2 &= s & Constants.vbCrLf
      Next
      MessageBox.Show(s2)
      ComboBox1.Visible = True
   End Sub

if not, sorry.

I am sorry, I think, I didn't explain well.


Normally, while we click on combobox, it will show the collection of items it contains. [combobox opens when we click on it]

I want to show all collection of items [or open combobox] without clicking it.

in form load event : combobox.visible=false

in button click event: combobox.visible=true
[combobox.open..... or something like that]
so, what should be the command to open combobox.????

ah. hehe. sori. you mean, this?

VB Code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
      ComboBox1.DroppedDown = True
   End Sub

If this is to force the user to pick an item before they continue with the form, it may be best,
at least easier, to pop up another form with all the items listed, say, in a listbox,
when they choose one, it could close and set the corresponding item on the combo box
on the first screen.
