创建一个依赖于Umbraco母版页的“普通”ASP.NET页面

Question

Is it possible in Umbraco to create a normal webforms page which inherits the main Umbraco master page?

My client has a requirement for some complex functionality which needs to be done in a page outside the context of the CMS.

I wonder whether it's possible to fire up the Umbraco context manually from within the constructor of a "normal" page. At the moment I just get the error:

Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.NullReferenceException: Object reference not set to an instance of an object. at umbraco.item..ctor(IDictionary elements, IDictionary attributes) at umbraco.presentation.templateControls.ItemRenderer.GetFieldContents(Item item) at umbraco.presentation.templateControls.ItemRenderer.ParseMacros(Item item) at umbraco.presentation.templateControls.Item.OnInit(EventArgs e) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Control.InitRecursive(Control namingContainer) at

thanks Kris

Answer 1

You can use alternate templates to reference a template directly without having a Content Page associated with it.

You can reference it in these ways:

http://www.yourdomain.com/page.aspx?altTemplate=templatename

http://www.yourdomain.com/page/templatename.aspx

That would prevent users from deleting the node.

Does that help?

Answer 2

U can inherit from umbraco master pages specify your masterpages manually like this

MasterPageFile="../masterpages/umbracoPage.Master"

This works for an .aspx page where you are specifying this page in the plugin directory

Answer 3

I think that you can achieve what you are asking;

The usual way to take a page out of the control of Umbraco is to use the web.config keys umbracoReservedUrls and umbracoReservedPaths - these are the keys installed with 4.11.1:

<add key="umbracoReservedUrls" value="~/config/splashes/booting.aspx,~/install/default.aspx,~/config/splashes/noNodes.aspx,~/VSEnterpriseHelper.axd" />
<add key="umbracoReservedPaths" value="~/umbraco,~/install/" />

Secondly if your top level master page contains no umbraco items or macros or anything you can always switch to a masterpage during the Page PreInit event

protected void Page_PreInit(Object sender, EventArgs e)
{
    this.MasterPageFile = "/umbraco/masterpages/default.master";
}

Or you could use the technique that @BeaverProj outlines.

EDIT

Looking at your comment I think that you can get at umbraco data without being in umbraco 'context'. Add project references to cms.dll and businesslogic.dll (umbraco will have dropped them in the bin) and then you can use the umbraco framework without the wrapper controls. For example the internal editMacro.aspx page uses the framework directly:

                <asp:DropDownList OnPreRender="AddChooseList" runat="server" ID="macroPropertyType"
                    DataTextFormatString="" DataTextField='macroPropertyTypeAlias' DataValueField="id"
                    DataSource='<%# GetMacroPropertyTypes()%>' SelectedValue='<%# ((umbraco.cms.businesslogic.macro.MacroPropertyType) DataBinder.Eval(Container.DataItem,"Type")).Id %>'>
                </asp:DropDownList>
