Sorry Erel,

I should have said i have several edit text boxes. i want to set properties etc in a for each group.


in vb similar was

B4X:

For each control in form
if control=textbox then
end if
next

I would also be checking that each text box has been filled in.

Are you storing the editboxes in an array?

hi Grant,

No. if i do that i would not really need to use For Each. The structure of a traditional For Each is that each control/view can be addressed based on its type not its name.

Thanks for the reply

You can do:

B4X:

For i = 0 To Activity.NumberOfViews-1
   If Activity.GetView(i) Is EditText Then
      Dim ET As EditText = Activity.GetView(i)
      Log(i&" "&ET.Text)
       'And anything else
   End If
Next

If the EditTexts are on a Panel, change Activity for PanelName.

All a for each loop does is iterate through a list/array of objects, returning an object of your type cast for each object. With that being said, you need a list/array to iterate through.

For me, if you're not wanting to use an array or list, then you could put the edits on a panel and loop through them that way.

EDIT: Looks like steve beat me to the punch
