Is this a bug in WebMatrix PageData?

Mar 29, 2011 09:42 AM|LINK

I met the same problem as follow link:

http://stackoverflow.com/questions/5127284/is-this-a-bug-in-webmatrix-pagedata

The answer to this link is only available to "from a content page to a layout page",

but I need "from a content page to a partial page", it still cause the problem.

Any solution? thanks.

yeah, i'm interested in this "bug" too.

I have partial page "xxx.vbhtml" and in it I have PageData("yyy")="xxx"

and in calling page I use @RenderPage("xxx.vbhtml"), to get code in xxx.vbhtml running.

So if I check PageData("yyy") after RenderPage function is used, PageData("yyy") is still nothing... :(

This is going to sound trite, but the behavior is by design and not a bug. When a partial page is initalized, a copy of the PageData dictionary is passed to it, which is why the values remain unaffected in the original page.

To share values across pages and partials for the lifecycle of a request, you could use Context.Items. Alternatively, you could drop in a dictionary or an ExpandoObject inside PageData and use that to share values:
```
@{
    Page["Shared"] = new Dictionary<string, string>();
    Page.Shared["Title"] = "Test";
    @Page["shared"]["Title"]

    @RenderPage("~/Partial.cshtml")

    @Page.Shared["Title"]
}

// Partial.cshtml
@{
    Page.Shared["Title"] = "Updated title";
}
```

Thanx, that changes my logic a bit.

I just wanted to have some shared "include", where all initialization is done and some global variables are created and initialized...

Thanks for the answer, and it makes sense, but that behaviour is far from obvious.

Where in the documentation / MSDN / whereever else woudl I have gone to find that out?

You can use the AppState dictionary for global variables:
```
App.Color = "red";
App.Discount = 10;
```
