Combining handlers...

I have:

Private Sub txtMileage_Validated(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtMileage.Validated
 
      Dim strVal = txtMileage.Text
.
.  
      txtMileage.Focus()
.
.
I want to turn this to handle 2 more text box entries, some thing like:

Private Sub txtMileage_Validated(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtMileage.Validated, txtMiles.Validated, txtGas.Validated  '<--????
 
      Dim strVal = sender.Text    '<---????
.
.
     sender.Focus()   '<--- ?????

But I am not sure about the syntax of my code marked with '<--- ?????

Question: What is the correct syntax to accomplish this.

Also, what is the difference between Validated and Validating events and their use?

Thank you

Generally speaking you can cast the sender object to a textbox:

    Private Sub txtMileage_Validated(ByVal sender As Object, ByVal e As System.EventArgs) Handles txtMileage.Validated, txtMiles.Validated, txtGas.Validated  '<--????

        Dim txtbox As TextBox = DirectCast(sender, TextBox)
        Dim strVal As String = txtbox.Text

        txtbox.Focus()
    End Sub

Open in new window

You can also test if it's a specific textbox with code like this

If sender is txtGas Then

Open in new window


The main difference is that they occur at different points in the validation cycle.  See more about Validating, Validated etc. here:
