Hello,
I've created one aspx page Default.aspx. It contains iframe with child.aspx. File Child.cs contains web methods which should be called by parent page.
As I understand I need to receive the instance of Child class so then I'll be able to them call. How can I make this?
I will be really appreciated for constructive solution,
Default.aspx (Parent page)
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Parent_Child_Iframe._Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<body>
<form id="form1" runat="server">

<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:Button ID="btGetDataFromChild" runat="server" Text="Get Data from Child" />
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<iframe id="I1" height="300px" name="I1" src="child.aspx" width="400px"></iframe>
</ContentTemplate>
</asp:UpdatePanel>
</div>
</form>
</body>

Child.aspx
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Child.aspx.cs" Inherits="Parent_Child_Iframe.Child" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<br />
<br />
<br />
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
</div>
</form>
</body>
</html>
Child.aspx.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace Parent_Child_Iframe
{
public partial class Child : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
public string getResultData ()
{
return TextBox1.Text + TextBox2.Text;
}
}
}
So How I can call getResultData () from Child.aspx.cs by clicking Button on the parent page. The main difficulty is that I can't use Javascript to collect the information from TextBoxes because the task is more complicated and I can use only server methods.
Thank you in advance, Best wishes, Greg.
