Razor Func mixed with MvcHtmlString?

You could use the text tag to combine everything into one parameter.

I'm no guru in Razor syntax, but trying to build a generic library using a fluent-style à là Telerik's GUI components. I have the following pieces (approximately): public static MyBox Box(this HtmlHelper helper) { return new MyBox(helper. ViewContext); } and: /// /// geekswithblogs.net/shaunxu/archive/2010/... /// public class MyBox : IHtmlString { private readonly ViewContext _viewContext; private string _content; private string _title; public MyBox(ViewContext viewViewContext) { _viewContext = viewViewContext; } /// /// See: http://haacked.com/archive/2011/02/27/templated-razor-delegates.aspx /// /// /// public MyBox Content(Func value) { _content = value.

DynamicInvoke(_viewContext).ToString(); return this; } /// /// See: http://haacked.com/archive/2011/02/27/templated-razor-delegates.aspx /// /// /// public MyBox Content(params Func values) { foreach (var value in values) { _content += value. DynamicInvoke(_viewContext).ToString(); } return this; } public MyBox Content(MvcHtmlString content) { _content = content.ToString(); return this; } public MyBox Title(string title) { _title = title; return this; } public string ToHtmlString() { using (var stringWriter = new StringWriter()) { WriteHtml((TextWriter)stringWriter); return stringWriter.ToString(); } } public void Render() { using (var writer = new HtmlTextWriter(_viewContext. Writer)) WriteHtml(writer); } protected virtual void WriteHtml(TextWriter writer) { writer.

WriteLine(""); writer. WriteLine("" + _title + ")); writer. WriteLine(_content); writer.

WriteLine(""); } } I also have a set of Html extension methods that return MvcHtmlString's. One example is (simplified): public static class GuiElementExtensions { private const string FieldContainerHeadingTemplate = @" {0} "; public static MvcHtmlString GuiFieldContainerHeading(this HtmlHelper helper, string text) { return new MvcHtmlString(String. Format(FieldContainerHeadingTemplate, text)); } } Then, in my .

Cshtml file, I do the following: @using (Html.BeginForm()) { @(Html.Gui() .Box() . Title("") . Content( @ This is the cool Gui.

Box ) ) } Which calls public MyBox Content(Func value), and works. Similarly, when I try the following: @using (Html.BeginForm()) { @(Html.Gui() .Box() . Title("") .

Content( Html. GuiFieldContainerHeading("SubHeading 1") ) ) } It happily calls public MyBox Content(MvcHtmlString content) and works as expected. But, however, when I try to do the following, I can't wrap my head around how the Razor compiler engine works.

How do I get it to return the sum of @ This is Gui().Box() (which is a Func) Html. GuiFieldContainerHeading("SubHeading 1") (which is an MvcHtmlString) as either one object (be it a Func, MvcHtmlString, whatever, or a list of objects? I would like to write generic Razor syntax inside the parameter list to the Content function in my MyBox class, like this: @using (Html.BeginForm()) { @(Html.Gui() .Box() .

Title("") . Content( @ This is Gui().Box() Html. GuiFieldContainerHeading("SubHeading 1") Html.

TextBoxFor(model => model. Name) @ ) ) } Am I on the right track whatsoever, or is there a much simpler way of doing what I want? I want to gather all the "common gui elements" in our system in a common DLL, so not every developer in my organization needs to reinvent the wheel on each project.

Any help appreciated. OK, next problem: I have generalized the Box into a Container, and created two subclasses, Box and HighlightArea. However, using the following code, the Razor compiler kicks me with the message Inline markup blocks (@Content) cannot be nested.

Only one level of inline markup is allowed. The code not working, is: @(Html.Gui() .Box() . Title("BoxTitle") .

Content(@ This is the box content @Html. GuiFieldContainerHeading("This is the heading") @(Html.Gui().HighlightArea() . Content( @Html.

ValidationSummary() @Jalla ) ) ) Do we have a workaround for this? Or is my approach not feasible? Asp.

1 Your example containing This is Gui().Box() is a bit confusing. It looks as if it contains some C# code but it's probably not supposed to be. – Codo Sep 21 '11 at 7:46 Thanks.

I've updated the question to avoid any confution. Any thoughts on the question other than the confusion? – Erik A.

You could use the tag to combine everything into one parameter. @using (Html.BeginForm()) { @(Html.Gui() .Box() . Title("") .

Content( @ This is Gui. Box @Html. GuiFieldContainerHeading("SubHeading 1") @Html.

TextBoxFor(model => model. Name) ) ) } I guess your example isn't really working. If I'm not mistaken you could get it working like this: @ This is Gui.

Box + Html. GuiFieldContainerHeading("SubHeading 1") + Html. TextBoxFor(model => model.

Name) + @ But the tag seems easier.

Worked like a charm. Thanks! :) – Erik A.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
