List box to text box

[LeoLionHeart]

hi,

I have a web form with a list box and a textbox.

What I want to do is everytime a user changes the item selected in the list box the new item to be displayed in the text box.

Any ideas?

I want to use Jscript for this, otherwise it will be slow.

Any help would be appreciated.

You can set the autopostback of the listbox to true and use the code:

Protected Sub ListBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
TextBox1.Text = ListBox1.Text
End Sub

This doesn't work. I have a value of nothing or blank when i set the autopostback to true and use the following.

    Private Sub lstQual_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstQual.SelectedIndexChanged
        Dim str As ListItem = Me.lstQual.SelectedItem
        Dim a As String = Me.lstQual.SelectedValue
        Me.txtUpDate.Text = Me.lstQual.SelectedValue
    End Sub

Any ideas?

Try this:

Private Sub lstQual_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstQual.SelectedIndexChanged
  txtUpdate.Text = lstQual.SelectedItem.Value
End Sub

..see if that works.
