If True Then

What you are expecting there? Check in debug mode this If condition is returning True or not?

Try something like:
            Dim Passed As Boolean = True 

            If TextBox1.Text.Trim = "" Then
                TextBox1.BackColor = Color.Red
                Passed = False
            End If
            If TextBox2.Text.Trim = "" Then
                TextBox2.BackColor = Color.Red
                Passed = False
            End If
            If TextBox3.Text = "" Then
                TextBox3.BackColor = Color.Red
                Passed = False
            End If

            If Passed Then
                'code to save data
            End If

Open in new window


*Be sure to reset the color of the TextBoxes when data is entered!

Ya good, but the user may enter the in t1 and t3, and leave t2, i want to color t2 only. then this one will not be ideal

use

if isempty(TextBox1) then
TextBox1.BackColor = Color.Red
elseif isempty(TextBox2) then
TextBox2.BackColor = Color.Red
elseif isempty(TextBox2) then
TextBox2.BackColor = Color.Red

end if
