Hi

Can you please add a SelectedItem property - with that one can get the selected item outside the item click event. I am assuming this can use the .SelectedIndex property is such has a get and a set.

eg.

B4X:
Dim y As String = SD_xComboBox1.SelectedItem

and perhaps

B4X:
SD_xComboBox1.SelectedItem = "ABC"

Only if possible.

Use ByValue.

B4X:
SD_xComboBox1.ByValue = "ABC"

Update 0.06
  • Added OpenList event. It is raised when you click on the ComboBox and the list opens

Example to close the keyboard when the ComboBox is opened
B4X:
Private Sub SD_OpenList
    Log("Oper DropDown")
    #if B4A
        Dim Ph As Phone
        ' B4XPage
        Ph.HideKeyboard(B4XPages.GetManager.GetTopPage.Parent.NativeType)
        ' Normal
        Ph.HideKeyboard(Activity)
    #else if b4i
        ' B4XPage
        Root.As(NativeObject).RunMethod("endEditing:", Array(True))
        ' Normal
        Page1.RootPanel.As(NativeObject).RunMethod("endEditing:", Array(True))
    #End If
End Sub
