Problem - DI to a page having .NET 2.0 Master page

**Hasith** · 07-21-2007, 11:53 AM

Hi,

For last 2 days I'm struggling to inject a message to a page having .NET 2.0 master page (not Spring master pages). It works perfectly on pages without a master page.

I tested on 1.0.2 and 1.1 latest version but without any success. I have the following in my web.conf.

Code:

  <spring>
    <context type="Spring.Context.Support.WebApplicationContext, Spring.Web">
      <resource uri="config://spring/objects"/>
    </context>
    <objects xmlns="http://www.springframework.net"> 
      <object type="~/pages/ContentPage.aspx">
        <property name="Title" value="Spring DI"/>
      </object>
      <object type="~/pages/PlainPage.aspx">
        <property name="Title" value="Spring DI"/>
      </object>
    </objects>
  </spring>

"PlainPage.aspx" has no master page definition and it works well. "ContentPage.aspx" is the page which has .NET 2.0 master page and it doesn't work at all.

I'm quite surprised to see no Google post on this matter. Am I doing something totally stupid

? Please advice.

Thanks in advance

Hay this is really interesting. It seems I'm able to inject properties other than "Page.Title".

I added a new DI property ("Message") and now my configuration looks like following:

Code:

  <spring>
    <context type="Spring.Context.Support.WebApplicationContext, Spring.Web">
      <resource uri="config://spring/objects"/>
    </context>
    <objects xmlns="http://www.springframework.net"> 
      <object type="~/pages/ContentPage.aspx">
        <property name="Title" value="Spring DI"/>
        <property name="Message" value="Spring DI Message"/>
      </object>
      <object type="~/pages/PlainPage.aspx">
        <property name="Title" value="Spring DI"/>
      </object>
    </objects>
  </spring>

Injection happens for property "Message", but not for property "Title" even on the same page (ContentPage.aspx).

I think I have selected a really strange starting point to Spring by using "Page.Title" in my tests. Can anyone explain what is happening here?

Not sure if it helps you, but I'm using Spring to do DI into Pages & Master Pages with ASP.Net, my configuration [the relevant bits] is as follows:

Code:

<object type="Default.master" abstract="true">
  <property name="SomeMagicStrategy" ref="SomeMagicStrategy"/>
</object>

<object id="BasePage" abstract="true">
  <property name="MasterPageFile" value="~/Default.master"/>
</object>

<object type="Default.aspx" parent="BasePage"/>

I can't comment on setting Page title however, sorry dude

Hi,

It seems your title goes /dev/null. Don't you get any exception?

How does your masterpage.master and context.aspx <head> html code look like?

Maybe you placed the <head runat=Server> element on your content.aspx outside a <asp:content> element?

hope this helps,
Erich
