//this is validation method
       protected bool Validation()
       {
           bool returnValue = false;
           try
           {
               if (string.IsNullOrEmpty(txt1.Text))
               {
                   Label1.Text = "Please Enter txtbox1 value";
                   returnValue = false;
                   txt1.Focus();
               }
               else if (string.IsNullOrEmpty(txt2.Text))
               {
                   Label1.Text = "Please Enter txtbox2 value";
                   returnValue = false;
                   txt2.Focus();
               }
               else if (txt1.Text != txt2.Text)
               {
                   Label1.Text = "Doesn't match the txtbox1 and txtbox2";
                   returnValue = false;
                   txt1.Focus();
               }
               else
               {
                   returnValue = true;
               }
           }
           catch (Exception Ex)
           {
               Label1.Text=Ex.Message
           }
           return returnValue;
       }
//in button click event or textchanged event you can write like this

 if (Validation())
                {
//do something here.....
                }
