Try:
Private Sub CheckBox_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox3.CheckedChanged, CheckBox2.CheckedChanged, CheckBox1.CheckedChanged
Dim sb As New System.Text.StringBuilder
sb.Append(CStr(IIf(CheckBox1.Checked, "1 ", "")))
sb.Append(CStr(IIf(CheckBox2.Checked, "2 ", "")))
sb.Append(CStr(IIf(CheckBox3.Checked, "3 ", "")))
TextBox1.Text = sb.ToString.Trim
End Sub

@user495854 is your problem that my answer is ugly with a large number of checkboxes (fair enough) or that it doesn't work even with just 3 checkboxes (if so, how doesn't it work)?

I do not think this is worth a full answer but here is a fix to hawbsl's so that you do not get the trailing comma: Dim sb As New System.Text.StringBuilder Dim text As String sb.Append(CStr(IIf(CheckBox1.Checked, "1, ", ""))) sb.Append(CStr(IIf(CheckBox2.Checked, "2, ", ""))) sb.Append(CStr(IIf(CheckBox3.Checked, "3, ", ""))) text = sb.ToString If text.EndsWith(", ") = True Then TextBox1.Text = text.Substring(0, text.Length - 2) Else TextBox1.Text = text.Trim End If

I think he wanted it to be just like yours, but with commas separating the numbers and with no trailing comma. I sort of think, maybe, based on his duplicate question that is what he wanted. Your answer is correct based on what he put in THIS question so I gave you +1 =)
