using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; namespace Validation_on_textbox { public partial class Form2 : Form { public Form2() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { foreach (Control c1 in this.Controls) { if (c1 is TextBox) { if (c1.Text == "") { MessageBox.Show("Name Field cannnot be blank"); c1.BackColor = Color.Orange; textBox1.Focus(); } else { MessageBox.Show("Correct"); c1.BackColor = Color.White; } } } } } }

Just write this code on the click of button and your problem will be solved.
private void button1_Click(object sender, EventArgs e)
{
if(textBox1.Text=="")
{
textBox1.BackColor = Color.Red;
}
}

Hi,
You can do like this
private void button1_Click(object sender, EventArgs e)
{
bool isValid = true;
textBox1.BackColor = System.Drawing.Color.White;
textBox2.BackColor = System.Drawing.Color.White;
textBox3.BackColor = System.Drawing.Color.White;
if (textBox1.Text == "")
{
isValid = false;
textBox1.BackColor = System.Drawing.Color.Red;
}
if (textBox2.Text == "")
{
isValid = false;
textBox2.BackColor = System.Drawing.Color.Red;
}
if (textBox3.Text == "")
{
isValid = false;
textBox3.BackColor = System.Drawing.Color.Red;
}
if (isValid)
{
//do your code
}
}
Regards,
Iftikar
