// return;
//}
//else
//{
// e.Cancel = false; errorProvider1.SetError(txtUID, "");
//}
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 (txtemail.Text.Length > 0 && txtemail.Text.Trim().Length != 0)
{
if (!rEmail.IsMatch(txtemail.Text.Trim()))

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();
