HtmlHelper Using ViewContext.Writer Not Rendering Correctly?

Aug 30, 2010

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:

<h1>Default Template</h1>
<% Html.ContentArea("Main"); %>

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");

AJAX :: ComboBox Not Rendering Correctly In MasterPage?

Mar 15, 2011

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:

Web Forms :: Menu Control Not Rendering Hover Styles Correctly

Aug 22, 2010

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:

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.

Web Forms :: TreeView Control Not Rendering Styles Correctly In Chrome, Firefox, Safari, But Fine In IE

Feb 15, 2010

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.

C# - How To Dynamically Retrieve All The Possible Attributes (variable Attributes) Values Of One Of The Xml Node

Aug 10, 2010

I am using the following XML structure

<SERVER NAME="A3" ID="3" Parent="XYZ"></SERVER>
<SERVER NAME="A5" Parent="abc" value="10"></SERVER>

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 ?

Test Output From HtmlTextWriter?

Mar 1, 2011

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">

MVC :: Using The AttributeCollection And HTMLTextwriter With Readonly Property

Dec 17, 2010

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+.

LoadControl - How To Add Attributes

Jun 30, 2011

I have a usercontrol that I load dynamically:

Sub PageLoadEvent()
Dim ctlIntrotext As Control = LoadControl("tryktabKapacitet.ascx")
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...

<uc9:TryktabKapacitet ID="TryktabKapacitet1" OnBtnNulstilClick="TryktabKapacitet1_BtnNulstilClick" OnSetAllModulesK="TryktabOptimering1_SetAllModules"
OnBtnClick="TryktabOptimering1_BtnClick" runat="server"></uc9:TryktabKapacitet>

Different Name And Id Attributes On A Form Element?

Dec 23, 2010

I 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.
