Hello,

How do you use Request.Form["HiddenField"] when the first page is using a
MasterPage?

Thanks, sck10
 
Hello Steve,

Do you mean in the original page, the hidden fields are put on MasterPage's
content? If so, this does make the identification of the hidden
fields(form items) in target page abit difficult. Becaue for controls put
in Master page, its name and id will be mangled. For example, the following
html control in master page

=========
<input id="hidden1" name="hidden1" runat="server" type="hidden"
value="hidden1 value" />
<input id="hidden2" name="hidden2" runat="server" type="hidden"
value="hidden2 value" />
===========

will be rendered as below finally:

<input name="ctl00$hidden1" type="hidden" id="ctl00_hidden1"
value="hidden1 value" />
<input name="ctl00$hidden2" type="hidden" id="ctl00_hidden2"
value="hidden2 value" />

Thus, on the target page, you can not directly use the original
hiddenfield's name to quey the Request.Form collection. One flexible means
is to query the Request.Form collection and find the one that contains the
hiddenfield's unmangled name. e.g.

========in target page===============

protected void Page_Load(object sender, EventArgs e)
{


foreach (string key in Request.Form.Keys)
{
if(key.Contains("hidden1"))
Response.Write("<br/>" + key + ": " + Request.Form[key]);
}
}
==============================

Hope this helps.

Hi,
Becaue for controls put in Master page, its name and id will be mangled.

.... which you can work around by using the .ClientID-property.

Thanks Walter, I will try your suggestion.

Hi,
I think what you mentioned should be "Control.UniqueID" :)

sorry for my posting, I wasn't reading carefully enough and assumed a
client-side thing (i.e. some JavaScript looking for the control). :-P

Cheers,
