Question

I have a C# aspx form in which I need to input it’s data into an SQL database and then return a response saying successful or not. I have no idea how to get the form data that is sent from the Default.aspx page. My basic code structure is below:

Default.aspx

<form runat="server" name="aForm" action="Results.aspx" method="post" onsubmit="ValidateForm()">  
  <input name="firstname" type="text" />
  <input name="surname" type="text" />
  <input type="submit" value="Submit" />
</form>

Results.aspx.cs

public partial class AwardsForm : System.Web.UI.Page {

  protected void Page_Load(object sender, EventArgs e) {

    if (!this.IsPostBack){
        Response.Redirect("Default.aspx");
    } else (this.IsPostBack) {
        writeResults(FormSubmit()); 
    }

    protected boolean FormSubmit() {
      // get form data and insert it into SQL
      // return true/false based on success
    }

    protected void writeResults(boolean results) {
      if (results == true) {
        Response.Write ("Success");
      } else {
        Response.Write ("Failed");
      }
    }

}

You can get the posted form data through Request.Form["key"], or, if your form elements are decorated with runat="server" then you should be able to grab them by id right in your code behind

<asp:TextBox id="yourTb" runat="server"></asp:TextBox>

string postedText = yourTb.Text;

Or you can do (though this is much less common)

<input type="text" runat="server" id="yourOtherTb" />

string otherPostedText = yourOtherTb.Value;

Or if you’re working with purely html form inputs:

<input type="text" id="clientTb" name="clientTb" />

string clientText = Request.Form["clientTb"];
