Question

this is driving me crazy.

I have a piece of code on a Windows Form Control, this code ensures the form clears and put the focus back to the first Control (Phone Number). The problem is I am using On-Leave Event Handles and this handler contain the Validation code so that the Phone is validated when the use leaves the control.

When I hit Reset or Exit of the form, it not only clears the form, it also sends the focus back to the Phone field, causing the control (Textbox) to Validate.

I need the focus on the Phone control with at the validation on focus, is there a way I can prevent this behavior?

private void txtPhone_Leave(object sender, EventArgs e)
        {
             Int64 ConvertPhone;
            if (txtPhone.Text.Trim().Length != 10)
            {
                lblPhoneError.Visible = true;
                lblErrorIndicator.Visible = true;
                lblErrorIndicator.Text = "*Valid 10 digit phone number required";
            }

            else if (Int64.TryParse(txtPhone.Text, out ConvertPhone))
            {
                lblPhoneError.Visible = false;
                lblErrorIndicator.Visible = false;
                txtPhone.MaxLength = 10;
                txtPhone.Text = txtPhone.Text.Substring(0, 3) + "." + txtPhone.Text.Substring(3, 3) + "." + txtPhone.Text.Substring(6, 4);
           }

        }

 private void btnClear_Click(object sender, EventArgs e)
    {
        txtPhone.Clear();
        txtPhone.Focus();
    }


    private void txtPhone_Enter(object sender, EventArgs e)
    {
        txtPhone.Text = txtPhone.Text.Replace(".", "");
    }

Thanks everyone!

if (txtPhone.Text.Trim().Length != 10)
{

            if (txtPhone.Text != "")
            {
                lblErrorIndicator.Visible = true;
                lblErrorIndicator.Text = "*Valid 10 digit phone number required";
            }
        }

private void btnClear_Click(object sender, EventArgs e)
{
txtPhone.Clear();
lblErrorIndicator.Text=””;
txtPhone.Focus();
}

I can understand your problem but tell me what you want to do at the end?
