Validate Text Box

Introduction:
      Today, we discussed about How to validate Text Box with Error Provider in C#.Net? .
Conditions:
    TextBox should enter only integer.
    create one validation event for integer

Here the Code:

protected void textBox1_Validating (object sender,
   System.ComponentModel.CancelEventArgs e)
{
   try
   {
      int x = Int32.Parse(textBox1.Text);
      errorProvider1.SetError(textBox1, "");
   }
   catch (Exception ex)
   {
      errorProvider1.SetError(textBox1, "Not an integer value.");
   }
}

Call this event in constructor
this.textBox1.Validating += new

System.ComponentModel.CancelEventHandler(this.textBox1_Validating);
