On an event, the sender is associated with the control that initiated the event. Through DirectCast I can retrieve information about that control and store the information into an array or several arrays. At the same time, I need to change the state of a different type of control. These two controls are located next to each other on the same form. I know my position within the array by DirectCasting the Object sender.
How do I change the CheckState of the CheckBox that sits to the right of the TextBox which generated the event
Events and loss of control indexing

Just after I posted it hit me:
Private Sub TextBox1_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.Leave, TextBox2.Leave...
Dim ItemIDs(9) As String
Dim Handles(9) As Short
Dim checkBox() As CheckBox = {checkBox1, checkBox2} ' Initialize array with existing CheckBox names
Dim index = DirectCast(sender, TextBox).Tag
ItemIDs(index) = DirectCast(sender, TextBox).Text
Handles(index) = DirectCast(sender, TextBox).Tag
checkBox(index).CheckState = CheckState.Checked
End Sub
The contents of the checkBox array points to the specific CheckBox control. That was an understanding I was looking for. checkBox(index) Inherits from CheckBox. Very cool!
I have 10 TextBoxes in a column with several controls to the right of each TextBox. The user may or may not start at the first TextBox. I need to work with the entire row of controls after the user Leaves the TextBox.
At the end of the day, I've got atleast 6 single dimension arrays to intialize.
I now know what to do, thanks for responding.
e-roo
SomeEvent(sender as Object, e as Eventargs
Dim Index as Int32 = Array.IndexOf(ControlArray, sender);
if Index > -1 then
Control TmpControl = ControlArray(Index)
Dim TmpCast as CheckBox = CType(TmpControl, CheckBox)
TmpCast.Checked = true
'... etc
'(I think)
end if
