//if (string.IsNullOrEmpty(txtemail.Text))

//{

// e.Cancel = true; txtemail.Focus(); errorProvider1.SetError(txtemail, " Please Enter E-Mail");

// return;

//}

//else

//{

//}

System.Text.RegularExpressions.Regex rEmail = new System.Text.RegularExpressions.Regex(@"^[a-zA-Z][\w\.-]*[a-zA-Z0-9]@[a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z][a-zA-Z\.]*[a-zA-Z]$");

if (tb.Text.Trim().Length == 0)

{

MessageBox.Show("Please Enter User Name");

e.Cancel = true;

return;

}

else e.Cancel = false;return;

}

for all validtion working properly but when my cursor is password or some other textbox and that time when i want to clear then it will be clear properly but focused not show on Name TextBox  .

 

this is my clear button code

 

txtName.Clear();

txtFname.Clear();

txtaddress.Clear();

txtmo.Clear();

txtemail.Clear();

radioButton1.Checked = false;

radioButton2.Checked = false;

txtUID.Clear();

txtpwd.Clear();

txtCpwd.Clear();

txtName.Focus();
