I try to run each control and then check what html did it render.
But this seems to me as an inaccurate method as whenever we add or remove the properties, or events of the control,the rendered HTML changes. Is there any book/tutorial/article to explain what is the standard HTML rendered by each asp.net control.
I have just run into a situation with a FormView control where any markup that is not given an ID and runat=server attribute is NOT rendered to the browser.
In other words, all of the extranneous markup (h#, fieldsets, legends, divs, labels, etc.) that are in my Edit Template DO NOT render to the browser at run-time. However, if I add an ID to any of those items and add runat="server" then they are rendered.
Has anybody every seen anything like this? Does anybody know what could possibly cause this?
When there is no DataSource assigned to my grid it doesn't render which is great!
When the datasource is empty it doesn't render - also great :-)
I am implementing some custom navigation so i want to know if there is a property that tells me if the dataview is rendered? If it is rendered i can show my custom bits otherwise i don't.
When I try to serialize <%: Html.CheckBox("Something", true) %> in jquery (using form.serialize()) I get two checkboxes, one says true, and the other false. I am aware that MVC renders true, false for checkboxes that are true, so if I wasn't coming through javascript, I'd just check for the presence of true, but how do I know if my checkbox is checked after doing form.serialize?

View 1 RepliesFor the ASP.NET Menu Server Control whose RenderMode is set to "List", there is an "Orientation" property which decides whether the menu would render as a horizontal or a vertical menu. I have compared the two HTML source code and was unable to find out which part of the HTML/CSS code set the orientation of the menu(unordered list).

How to access the HTML control values in form object, if runat="server", is not present in the HTML controls.
View 6 RepliesI know this is kind of obsessive, but is there a way to control the order that the TagBuilder class renders the attributes of an HTML tag when you call ToString()?
i.e. so that
var tb = new TagBuilder("meta");
tb.Attributes.Add("http-equiv", "Content-Type");
tb.Attributes.Add("content", "text/html; charset=utf-8");
tb.ToString(TagRenderMode.SelfClosing)
will return
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
not
<meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
Changing the order that you add the attributes doesn't change it, it seems to be rendering in alphabetical order
I want to know: what are the basic differences between html server controls and web server control. As I have gone though lots of surfing but couldn't find the exact answer.
View 5 RepliesWhen a .NET server control is rendered in a browser it is rendered as a html control. Then how a browser differentiate between a server control and a html control. If the two control rendered as same then how server side events fire for a server control? If u say by using runat="server" attribute then also we can add runt="server" for html controls to work at server side... so then how these are recognized?

View 1 RepliesI'm looking for an ASP.NET control that renders a tree structure, very much like the ASP.NET TreeView control, but filling the following requirements:
Dont uses tables for rendering tree structure.
Markup Adhering to valid XHTML 1.0 Strict.
Works with AND without javascript.
Also, if the control is licensed under a MIT och GPL licens that would be great, but commercial controls is also of interest.
Do anyone know of any such control? If not, well, then I'll simply have to write the control myself. More fun in my own opinion, but likely more time consuming.
