An ErrorProvider is an IExtenderProvider which provides extended properties for every control on the form that you add it to.

I did get the IconAlignment property to work but I had to set it programmically.īarb Private Sub TextBox1_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged ErrorProvider1.Clear() ErrorProvider2.Clear() ErrorProvider3.Clear() If Not TextBox1.Text = '' Then If TextBox1.Text = 0 Then ErrorProvider1.SetError(TextBox1, 'green') If TextBox1.Text = 0 Then ErrorProvider2.SetError(TextBox1, 'yellow') If TextBox1.Text = 0 Then ErrorProvider3.SetError(TextBox1, 'red') Dim s As String = CType(ErrorProvider1, ErrorProvider).Tag 'if you just try to set the properties for the textbox it doesn't work ErrorProvider1.SetIconAlignment(TextBox1, ErrorIconAlignment.TopRight) ErrorProvider2.SetIconAlignment(TextBox1, ErrorIconAlignment.BottomRight) ErrorProvider3.SetIconAlignment(TextBox1, ErrorIconAlignment.MiddleRight) ErrorProvider1.SetIconPadding(TextBox1, -15) ErrorProvider2.SetIconPadding(TextBox1, -5) ErrorProvider3.SetIconPadding(TextBox1, 5) End If TextBox2.Text = ErrorProvider1.GetError(sender) TextBox3.Text = ErrorProvider2.GetError(sender) TextBox4.Text = ErrorProvider3. The problem is that that's not how you use an ErrorProvider.

Also is there any way to look at a textbox and see what errors have been set for it. In order to provide a clear visual clue between errors and warnings its necessary to have two differing icons.
