Use The Html 'title' Attribute With Html.Encode()?
May 26, 2010
I've been tryin to find an example of the syntax for getting an html 'title' for a string when using Html.Encode(). I want to display the full name in the mouseover title, if it's too long.
Is there a way to do this without wrapping the string in a < span >, i.e.
<span title = "<%=Html.Encode(model.Name) %>"> //displays the full name on mouseover
<%=Html.Encode(model.Name.Substring(0, 10))%>... //displays the name up to a max length
</span>
I'm working on this big project in MVC ASP.NET w VB.NETOne of my views is getting me headaches since a few and i'm not sure what's up.I've used the Begin.Form and Html.Encode methods alot in my other views and i never had any problems. Now this new Create.aspx view for one of my object called Automation is giving me multiple build errors such as those cited in the title plus
Error 184 'Context' is not a member of 'ASP.views_automatisation_create_aspx'. BeginForm is not a member of 'Html' Encode is not a member of HTML
My header is as follow (just like all of my other working views headers) : \ <%@ Page Title="" Language="VB" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage(Of XXXXX_XXXXX.Automatisation)" %>
I've installed a Free TextBox editor to allow clients to do a write up about themselves and style it with HTML. Been reading about cross site script attacks (XSS) and want to make sure I'm correctly uploading the data collected with the Server.encode method.
I'd like to html encode all user input on the ASP.NET MVC 2 site but default. Can this be done anywhere on model binder level?
If I disable input validation for action -- I will need to html-encode every other value. If I keep ASP.NET request validation on -- it will throw erros "A potentially dangerous Request.Form value was detected from the client"
P.S. I do use encoding when outputting data (<%: %> syntax), but I'd like to encode everything on posting it too.
I have pages with special characters in the title for proper typography, for example it says Exchange ‘07 Groups" with a proper apostrophe, not a single quote. The HTML entity for the apostrophe is ‘
So, I've found that if I set the page title from VB, the title displays just fine, but as soon as an update panel updates that HTML entity gets re-encoded and displays incorrectly as "Exchange ‘07 Groups"
So here's my code where I simply set the page title, then an update panel, and a button to update it...
<script runat="server"> Protected Sub Page_Load(...) Handles Me.Load Page.Title = "Exchange ‘07 Groups" End Sub
I am working in a CMS where we use tokens ( which is turned into a user control. Is there a way to add the user control into an attribute value for our template style? example :
<div class="<$tokenName/$>" />
this currently outputs an encoded user control, which is then not parsed by IIS.
I have a large string containing a custom HTML tag (xxx). The tag also has two attributes. How would I retrieve the value of the two attributes and then place the tag and its content with a new string derived from those two attributes?
I'm trying to add a new html attribute to my ValidationSummary Html control like this:
<%= Html.ValidationSummary(new { id = "validationSummary" })%>
VS compiler has no problem with it, however when it comes to running it in the browser I get the nasty error message saying:
'System.Web.Mvc.HtmlHelper<Adgistics.Mvc.ViewModels.Forum.IForumCreateOutModel>' does not contain a definition for 'ValidationSummary' and the best extension method overload 'System.Web.Mvc.Html.ValidationExtensions.ValidationSummary(System.Web.Mvc.HtmlHelper, string)' has some invalid arguments
I'm trying to optimize SEO readability on our websites and one issue I've come across is ASP.NET butchering the title element of my MasterPage. Entered as such in my MasterPage (manually reformatted to remove line breaks caused by the <% %> tags):
As you can see ASP.NET is adding preceding and trailing line breaks where the <asp:ContentPlaceHolder /> is substitute becaused Visual Studio auto-formats <asp:Content /> to start and end with a line break. Obviously, this can be prevented in the Visual Studio formatting options, but this is not ideal because I only would want to remove that behavior for the TitleContent placeholder and not the rest.
Is there any way I can ensure my Title is trimmed before it is rendered? I am using MVC so code-behind is not an acceptable option.
An error occurred during the processing of /_layouts/MyPage/Info.aspx. Literal expressions like '<%$Resources:wss,okbutton_accesskey%>' are not allowed. Use <asp:Literal runat="server" Text="<%$Resources:wss,okbutton_accesskey%>" /> instead
That doesn't work in this situation as that would mean nesting the Literal between the quotes of the accesskey attribute, which causes a "The tag contains duplicate 'ID' attributes" error.
Is there a way to use a string from a resource without having to change the input to an asp:Button? I guess there has to be a way using <%=, but I don't know how I would address the resource itself?
I have been experiencing some very strange behavior using html buttons with the onserverclick attribute. What I am trying to do is use jQuery to designate the default button on the page. By default button I mean the button that is "clicked" when a user hits enter. In testing, I would hit enter while in an input field and sometimes the intended "default" button was clicked and the server side method defined in the corresponding onserverclick attribute was hit. Other times a post back was made without hitting the server method. In order to isolate the issue I created a minimal test case and found some very interesting results.
Client side: [Code] ....
Server side: public partial class admin_spikes_ButtonSubmitTest : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void ServerMethod1(object sender, EventArgs e) { _response.Text = "server method1 was hit"; } protected void ServerMethod2(object sender, EventArgs e) { _response.Text = "server method2 was hit"; } }
What I found was that everything worked as expected with this code except when I removed one of the input elements. In Firefox 3.6 and IE 8 when only one input exists on the page, hitting enter does not trigger the onserverclick, it makes a post back without even being jQuery "clicked" or actually "clicked". You can test this by starting with two inputs and clicking "test2". This will output "server method2 was hit". Then just hit enter and the output will be "server method1 was hit. Now take away an input and run the same test. Click "test2" see the results, then hit enter and you will see that nothing will change because the "test1" method was never hit. Chrome worked as expected
How do I create an ASP.Net MVC Helper for an Html.Label which takes in attributes? Currently when I define an Html.TextBox I am able to pass in a list of attributes. Sort of like below:
new {disabled="disabled", @class="pcTextBoxWithoutPaddingDisabled"})%>
However, it does not look as though the Html.Label has this feature. As a result, I have to define my labels using the label tag. Sort of like below: <label class="pcLabelBlackWithoutPadding"> I would like to be consistent I how my Html element get created. So, how do I create an Html.Label that will take in a list of attributes?
It doesn't seem that the Html.CheckBoxFor helper adds the correct "checked" attribute when rendering the HTML. I have a bool property rendered like so:
I have an ASP.NET content page. The HTML tag associated with the content page is declared in the master page. I need to add an attribute to the HTML tag from the content page. My problem is, I do not know how to access this HTML tag from the content page.
I'm new to ASP.NET and MVC in particular. Now, I'm trying to understand if I can easily get values of custom attributes of submitted data. For example, When writing something like this inside a form (which works and posts and I can get the checkbox value) <%= Html.CheckBox("cb1", new { listen = "listen:6" }) %> Can I get the value of "listen" directly or do I need JS? (I know I can just use hidden fields, but I'm I'm asking anyway)
I have a web user control menu of page. Now I want HOME (which is an hyperlink text) in menu to be Bold at the time default.aspx Loaded (Load event)! How can I do that If any one can provide code! I am using VB .Net at back.
I am using the MetaDataType DataAnnotation to validate my models in an MVC2 application. I also apply the DisplayFormat annotation so that currencies and dates are formatted the way I want. This method works for the original Html Helpers such as :
[Code]....
When I used the new strongly typed helpers:
[Code]....
the formatting never gets applied. Is there a way around this?
