I need to access a hidden HTML field on post back from the OnInit
method. This hidden field value has been set previously in the
Page_load event.
simplified example is as follows: IN THE CODE BEHIND
protected override void OnInit(EventArgs e)
{
Label1.Text = myHiddenFeild.Value;
}
protected void Page_Load(object sender, EventArgs e)
{
myHiddenFeild.Value = "Hello World";
}
protected void Button1_Click(object sender, EventArgs e)
{
//Just added so I could postBack
}
IN THE ASPX PAGE:
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<input type="hidden" runat="server" id="myHiddenFeild" />
<asp:Label ID="Label1" runat="server" Text="Label"></
asp:Label>
<asp:Button ID="Button1" runat="server"
OnClick="Button1_Click" Text="Button" /></div>
</form>
</body>
</html>
Expected Result
---------------------
When I press the button the label is updated with the hidden field
value " Hello World".
Actual Result
-------------------
Is nothing happens.
Debugging
-----------------
When debugging the hidden field value (myHiddenFeild) is empty in the
Oninit method, but as soon as it the execution reaches the Page_load
method then the myHiddenFeild as a value again.
Sorry if I'm being dense and staring the obvious in the face. As
always many thanks for any replys.
Cheers
Alun
