detect event starter, what info sender and e will return?

Question

Hello

MyForm_Load Event::
Dim boolVal As Boolean = Registry.CurrentUser.OpenSubKey(my app settings address).GetValue(ValueName, DefaultData)
SwitchButton1.Value = boolVal

and:

Private Sub SwitchButton1_ValueChanged(sender As System.Object, e As System.EventArgs) Handles SwitchButton1.ValueChanged
Registry.CurrentUser.CreateSubKey(my app settings address).SetValue(ValueName, ValueData, ValueKind)

SwitchButton1_ValueChanged will be called in 2 ways:
on formload .Value
or by clicking on it
both will return DevComponents.DotNetBar.Controls.SwitchButton for sender
anyway to distinguish them to call CreateSubKey only when clicking on it, not on form load?

(beside setting another boolean on form_load complete event and checking it)
Thanks :)

Hi @OSVBNET ,
Try adding events dynamically.

    Private Sub MyForm_Load(sender As Object, e As EventArgs) Handles MyBase.Load  
        SwitchButton1.Value = boolVal  
        AddHandler SwitchButton1.ValueChanged, AddressOf SwitchButton1_ValueChanged  
    End Sub  
  
    Private Sub SwitchButton1_ValueChanged(sender As System.Object, e As System.EventArgs)  
        Registry.CurrentUser.CreateSubKey(My app settings address).SetValue(ValueName, ValueData, ValueKind)  
    End Sub  

Best Regards.
