Question

I have a simple email form written in ASP.NET with the logic in the codebehind file. It’s all in C# (the logic that is…). Anyways, on page load I have the following:

protected void Page_Load(object sender, EventArgs e)
{
    RequestorName.Text = Request.Form["UserName"].ToString();
    RequestorTitle.Text = Request.Form["JobTitle"].ToString();
    RequestorEmail.Text = Request.Form["Email"].ToString();
    RequestorPhone.Text = Request.Form["Phone"].ToString();
    RequestorAddress1.Text = Request.Form["Address"].ToString();
    RequestorAddress2.Text = Request.Form["City"].ToString() + " " + Request.Form["State"].ToString() + ", " + Request.Form["Zip"].ToString();

}

This works great as it pulls the users information into a few fields so they don’t have to fill everything out by hand.

My other 2 methods in the code behind:

protected void SubmitForm_Click(object sender, EventArgs e)
{
    SendEmail();
}

protected void SendEmail()
{
    try
    {
        //compose email and send

    }
    catch (Exception ex)
    {
        ErrorMessage.Text = "Error: " + ex.ToString();

    }
}

On my form page the button code is this:

<center>
                <asp:Button runat="server" Text="Submit" ID="Submit" OnClick="SubmitForm_Click" class="button red" />
</center>

The error occurs when I click the send button on the form that generates the email and sends it. I can remove the Page_Load code and works great but I’d like to keep it there so the user doesn’t have to fill out as much information.

I’ve used my Google Fu and read a ton of threads/articles but can’t seem to find the solution…

Thanks for any assistance.

Add check for IsPostBack:

protected void Page_Load(object sender, EventArgs e)
{
  if (!IsPostBack) 
  {
    RequestorName.Text = Request.Form["UserName"].ToString();
    RequestorTitle.Text = Request.Form["JobTitle"].ToString();
    RequestorEmail.Text = Request.Form["Email"].ToString();
    RequestorPhone.Text = Request.Form["Phone"].ToString();
    RequestorAddress1.Text = Request.Form["Address"].ToString();
    RequestorAddress2.Text = Request.Form["City"].ToString() + " " +    Request.Form["State"].ToString() + ", " + Request.Form["Zip"].ToString();
  }

}
