The event handler 'OnClick' is not allowed in this page

[Rathinavel]

I have a page with a LinkButton and implemented "authorize_click" method in
the code-behind for the OnClick event. [code-behind class is part of the dll
in the GAC].

<asp:LinkButton ID="authorize" runat="server" OnClick="authorize_click">
Authorize</asp:LinkButton>

When I load the page, I get the below error,

An error occurred during the processing of . The event handler 'OnClick' is
not allowed in this page.

I don't want to have the implementation of the OnClick() method in the
script block. I prefer to keep it in the code-behind.

Please help.

Hi Rathna,

From your description, you're encountering some problem adding a custom
page(with codebehind and event handlers) into SPS 2007 site, correct?

I've performed some research according to the error messages you mentioned.
It seems for the event handler and codebehind, the following configuration
section in sps virtual server's web.config file may affect it:

===========
<SafeMode MaxControls="200" CallStack="false" DirectFileDependencies="10"
TotalFileDependencies="50" AllowPageLevelTrace="false">
<PageParserPaths>
<PageParserPath VirtualPath="/*" CompilationMode="Always"
AllowServerSideScript="true" IncludeSubFolders="true" />
</PageParserPaths>
</SafeMode>
===========

the "AllowServerSideScript="true" setting here may help eliminate the
error. here is a web article which provide a complete step for adding
custom page(that use codebehind) into SPS site:

Hi Steven,

Thanks for your advice.
The solution you have given works for a page without a master page.

In my case, the page is linked to a master page. I got other errors, when I
made changes to web.config for "PageParserPath".

I spent some more time and got a solution for this problem. Below is the
sample
code. Hope it will be useful for others.

Client Code (.aspx)
----------------------
<asp:LinkButton ID="authorize" runat="server" >Authorize</asp:LinkButton>

Codebehind (.cs)
---------------------
namespace SPLibrary
{
public class Default : Microsoft.SharePoint.WebPartPages.WebPartPage
{
protected LinkButton authorize;

protected override void OnInit(EventArgs e)
{
authorize.Click += new EventHandler(authorize_OnClick);
}

protected void authorize_OnClick(object sender, EventArgs e)
{
LinkButton authorise = FindControl("authorize") as LinkButton;
authorise.Text = "Label Changed";
// required business logic can be added.
}
}
}

Thanks for your followup Rathna,

So your final solution is using code behind to programmatically regsiter
the postback event handler. I agree that it's an elegant solution whch will
not require much changes. Also, thanks for sharing the result with the
community.

Have a good day!

Sincerely,
