Clearing multiple text fields

I tried searching for a solution, but couldn't find anything, so if I am re-asking a common question, don't beat me too badly.

For a class, I have to create a form that allows someone to enter in the names of six students, as well as five test scores each. It also averages the scores, and displays them in a label.

What I am wondering is if there is a way to clear the text from all 36 text fields, as well as the 6 labels without having to do everything individually?
I could certainly go through, and write out txtField1.text = String.Empty 36 times, but it seems there would be a more elegant solution.

Also, if there is a way to do so, would the same would apply for putting the data entered into an array, or saving it to a file?

You can use a loop of some sort, but exactly how to do it depends on how your controls are laid out and/or named. For instance, you had TextBoxes named TextBox1 to TextBox36 then you could do this:

vb.net Code:

For n = 1 To 36
    Me.Controls("TextBox" & n).ResetText()
Next

It's not really a good idea to use names like that though. Another option would be to have your controls in a TableLayoutPanel and then use nested loops to work through it column by column, row by row. As a last resort, you can just create your own array or collection and then loop through that.

I was just using txtField1 as an example.

I will try out your suggestion, though, and see how it goes. Thanks!

You can loop through the TextBox controls used in the form dynamically and set it to blank value

vb Code:

For Each myControls In Me.Controls
            If TypeOf myControls Is TextBox Then
                myControls.Text = String.Empty
            End If
        Next

same way, you can check the labels using "Label" instead of TextBox

Hope this helps

try this:

vb Code:

Public Class Form1
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim textboxes() As TextBox = Me.Controls.OfType(Of TextBox).ToArray
        textboxes = Array.ConvertAll(textboxes, AddressOf clearTextBox)
    End Sub
 
    Private Function clearTextBox(ByVal tb As TextBox) As TextBox
        tb.Text = ""
        Return tb
    End Function
 
End Class

Array.ConvertAll isn't really appropriate, given that there's no conversion occurring. If this is .NET 4.0 then lambda expressions don't have to return a value:

vb.net Code:

Dim textBoxes = Me.Controls.OfType(Of TextBox)().ToArray()
 
Array.ForEach(textBoxes, Sub(tb) tb.Clear())

If it's not .NET 4.0, or even if it is, you can just use a For Each loop:

vb.net Code:

For Each tb In Me.Controls.OfType(Of TextBox)()
    tb.Clear()
Next

This assumes that you do want to clear every TextBox on the form of course.
