What went wrong and how can I fix this issue?
don't answer that I could assemble the string in some other way. I want to know how I can achieve this with the HtmlTextWriter
I am building a simple CMS with asp.net MVC and I have almost all the parts working. I have one minor issue which I can't work out how to solve. I have a Html helper method that renders the content of area. This method however uses the Response.Write to write its content rather than returning a string. The reason for this is that I'm performing a partial request and hence do not have a string to return.
My template body looks like this:
<body>
<h1>Default Template</h1>
<% Html.ContentArea("Main"); %>
</body>
The problem I'm having is that the content renders above the H1 tag. My understand was that the h1 should already be in the response and my call to response.Write() would therefore append content after that point. This is obviously not happening. What am I missing here.
I've used partial requests before and they always render in the correct place. I haven't yet used them with MVC 2, this could possibly be the problem.
Below is the content area extension method. The widget render method varies and is where the partial request occurs. However even the start and end container tag render above h1 so it has to be something fundamental I'm doing wrong.
public static void ContentArea(this HtmlHelper htmlHelper, string areaName)
{
var container = new TagBuilder("div");
container.GenerateId(areaName);
container.AddCssClass("content-area");

When I add an ajax combobox (WindowsStyle Css) to a web page that uses a masterpage the arrow button is vertically offset from the rest of the combobox. however if I add it to page without masterpage then it works fine.I am using the images and provided css styling provided by ajax toolkit. I tried removing the site css file but that didn't help either. Any ideas what could be causing this? Code is below for a sample in Master/Content Page:

I've encountered was appears to be a strange bug with the menu control, and alas, I am unable to find much useful information on it (which leads me to believe I have something installed or confingured incorrectly). Here the problem:
When declaring a menu control with a staticHoverStyle, for example:
<asp:Menu
ID="navMenu"
DataSourceID="srcSiteMap" [code]....
Has no effect on the behavior of the control once it's rendered, neither in Firefox nor IE.In fact, using the source code at
http://msdn.microsoft.com/en-us/library/ms366731.aspx with no modifications also results in the hoverstyle not working.
This problem seems to be "fixed" if you specify the css attribute declaratively, for example, StaticMenuItemStyle-BackColor="Yellow".
Alternatively, if you specify RenderingMode="table" then the hoverstyle seems to work. It's only when you're using a cssclass with a list that things seem to mess up.
Finally, I notice that in the rendered html, the control embeds some styles between /* <![CDATA[ */ and /* ]]> */ comments that affects the final appearance of the menu control, sometimes overwriting a cssclass you specified (ex: the margin for dynamic menus can only be controlled with the HorizontalOffset property, and not by css). This is undesirable, but I don't see anything that seems to overwrite the behavior of hover elements. Actually, the .hoveritem class doesn't appear anywhere in the markup at all, but when you specify the StaticMenuItemStyle-BackColor property, then the value is rendered correctly in this block of styles.
I've defined node styles for my TreeView instance in markup (using <LevelStyles> for example). Everything renders correctly in IE7/8 but, when rendering in Chrome, Safari or FireFox, the styles are not being applied. From looking at the source code for the page, I can see that the various runtime css classes are being injected into the top of the page, but the class attributes on the <a> tags (within the generated TreeView HTML) are empty (class=""). In IE, the class attributes contain references to the classes that were injected into the page.
Can anyone explain why this is happening? I can see no logical explanation for this, and it's a big issue - My client primarily uses Safari, as they're Mac based.
I am using the following XML structure

I am accessing this xml file by using LINQ to XML in asp.net by using C#. I am able to access all the attributes of an XML node by explicitly specifying the name of the attribute. I want to write query on this xml file which reads all the attribute values of the xml node (In our example the node is SERVER) dynamically means I want to write the query which can read the read the value of the attribute Name & ID from first node, only name from second row, Name, ID & Parent from the third row , Name & ID from the fourth row, Name, Parent & Value from the fifth row & only Name from the sixth row without modifying the existing code every time. Once I add one of the attribute ( for example if I add the attribute ID in the sixth row ) in the above xml file then I dont need to modify my LINQ to XML query. My query should dynamically fetch the total number of attributes & display their values. Is their any way to do this ?
is it possible to get HtmlTextWriter of a control?
if no, then how can i call the RenderEndTag of a control in code behind?
i am facing a problem in my application. i extended the listbox user control and override its RenderEndTag event.
if i used the new listbox (Mylistbox) normally inside a WebPage, everything works fine. but when i put Mylistbox in a Webusercontrol and include the Webusercontrol in a WebPage, the RenderEndTag of the control is not called for some reason.
I have this code that creates a document, and want to show it in a new page. I'm new with the HtmlTextWriter class, and don't know how to accomplish this.

Quite simply I want to be able to test that a Asp.Net web forms server control is outputting the correct Html as it will be building dynamic content. I'm just starting to create the control and wanted to do it in a TDD style building up the Html that gets output. I've created a separate class to do the actual Html building so that I am able to test it in isolation outside of the normal Asp.Net pipeline.In my unit tests I can control what html is returned but I'm having problems confirming that the html contains the markup I am expecting for example:
<div id="wrapper">
<div id="fields">
</div>

Can you use FluentHTML or other alternatives in an web application user control?
Can you put a markup file in a System.Web.UI.Control like the System.Web.UI.UserControl but without the burden of the Page object?

I am using the AttributeCollection with the HtmlTextWriter objects and want to set the ReadOnly attribute.
It seems everything needs to be setup Attribute="value" but the readonly property just needs the name not ReadOnly=True.
Is there a way to just output ReadOnly with the AttributeCollection instead of ReadOnly=True?
You may be asking why, I don't know how compatible ReadOnly=True would be with older browsers and everything I design is compatible with ie4+.
I have a third party tool that creates an img tag through code using HtmlTextWriter's RenderBeginTag, RenderEndTag & AddAttribute methods. I want to get the resulting HTML into a string.
I tried the reflection method mentioned here but I get a error "Unable to cast object of type 'System.Web.HttpWriter' to type 'System.IO.StringWriter". The InnerWriter type of the HtmlTextWriter is of type HttpWriter.
how to copy the output HTML into a string?

If I have an HtmlTextWriter with some content in it, is it possible to append the output of ontrol.RenderControl to the existing content of the HtmlTextWriter directly?
Or do I always have to output to a separate HtmlTextWriter/StringWriter/StringBuilder and then append the StringBuilder?

I am creating a custom server control in which I place a RequiredFieldValidator. In the the Render method and I want to dynamically create a RequiredFieldValidator and render it to the HtmlTextWriter.
The problem is, when I call RenderControl on the RequiredFieldValidator, it only generates a span for me with no javascript or client side code.
How can I completely render a RequiredFieldValidator to an HtmlTextWriter?
I have a create view that I cannot set HTML attributes on. I have tried various ways but still cant set an attribute. Currently I'm trying this
<%: Html.TextBoxFor(model => model.itinerary, new { size = 60})%>
I have a usercontrol that I load dynamically:
Code:
Sub PageLoadEvent()
Dim ctlIntrotext As Control = LoadControl("tryktabKapacitet.ascx")
plh1.Controls.Add(ctlIntrotext)
End Sub
and then adds the sub to the Page_load, that works fine.However:
1) How do I call subs from the usercontrol?
2) How do I add the OnClick-events which I normally have in the webform source, see example...
Code:
<uc9:TryktabKapacitet ID="TryktabKapacitet1" OnBtnNulstilClick="TryktabKapacitet1_BtnNulstilClick" OnSetAllModulesK="TryktabOptimering1_SetAllModules"
OnSetOneModuleK="TryktabOptimering1_SetOneModule"
OnBtnClick="TryktabOptimering1_BtnClick" runat="server"></uc9:TryktabKapacitet>
I need to get my C# Web Application in VS 2008 Professional to compile. I have 2 projects in one solution.The first project, PowerMeter has an App_Code folder with namespace Inov.PowerMeter and the associated .aspx.cs files in the app reference it by using Inov.PowerMeter;. This code compiles fine and builds the powermeter.dll correctly. I have a second project called QuickMeter. The app_code for this creates a namespace Inov.Quickmeter and the aspx.cs files reference it correctly. But this doesn't compile.
View 1 RepliesI have a web form with usual elements (first name, last name, etc). The Postback URL is a different website altogether as the form is intented to post lead information to another website.
The site that accepts the lead is expecting First Name to come over as "FName", and Last Name to come over as "LName". Is there any way I can set the ID of a textbox to "txtFName", but submit it over the wire as "FName"? I tried changing the name attribute, but at runtime it sets the name = id.
