MVC :: Extend The HtmlHelper By Using Metadata / Access Metadata In HtmlHelper Extension Method?
Jan 9, 2010I would like to extend the HtmlHelper by using metadata (similar to DataAnnotaions metadata). Specifically I want to be able to add a 'Title' attribute to html controls that will then appear as a tooltip on the control. I would like to keep the tooltip text with my model, for example by adding 'Tiltle' metadata to the model as follows:
[DisplayName("User Id")]
[Title("Enter your 10 digit user id")]
property UserId { get; set; }
So the questions are:
1. How do I add metadata (such as 'Title') to my model?
2. How do I access this metadata in my HtmlHelper extension method?

What Function To Use Submit A Param In URL That Contains '&' W/o Using %26
Jul 14, 2010When I do window.open(url), I have to manually replace a value inside that url that contains '&' by '%26'. I am wondering whether there is a function on ASPNET side that I can manipulate that param value that contains '&' to containing '%26' without doing in javascript window.open(). URLEncode does not work nor URLPathEncode!

Crystal Reports :: Report Prompts For Param Values When Pageing?
Sep 14, 2010I have created a CR which uses two static parameter fields for 'DateFrom' and 'DateTo' on the report. The parameters are passed to the web page via a query string, and then I use Dim Fromdate As String = Request.QueryString("from") etc to send the parameter via code. The problem I'm having is this. The DateFrom and DateTo values are being sent to the report ( I simply use them in the report header to display the from and to dates selected by the user for the report ) and the report display's as expected. But when you click 'Next' in the multipage report, the report prompts with a parameter popup box to reenter the dates. Once you enter the values, you can page back and forth without any more interuptions.
Would anyone know what I have set wrong? Here is the code that I use to populat the report.
Dim reportpath As String = ""

WCF / ASMX :: Publish Enum Through Web Service Without Being Param/return Type?
Apr 30, 2010I have a webmethod that has three parameters:
public AuthenticationResult Authenticate(Enum type, string userName, string password) But the problem I had is that if a null/invalid enum is entered for the type variable it throws an error message.
So the obvious solution is to use a string/int instead but I am cannot do this as current users already use the existing webmethod.
So i was thinking:
public AuthenticationResult Authenticate(object type, string userName, string password) and handling the casting myself but the problem I had with this is that now my users do not have access to the Enum type.
So my question is can I publish the enum type without having it as a parameter/return value? Allow the client to access the Enum so they can pass it into the method. Would using a method that returned a type that was my enum work? Or is there a way to catch this custom error: (I dont think so as it appears to be on the client end when converting Enum to xml). The error is: (System.InvalidOperationException: There was an error generating the XML document. ---> System.InvalidOperationException: Instance validation error: '45465' is not a valid value for Enum.)
C# - Adding Own HtmlHelper In MVC 3
Feb 19, 2011 I am new to MVC and I am trying to create my own extension method so that I can add onto the html helpers that are available in my razor views. Html.DropDownListFor() lets you create a drop down list for any propery on your model. I would like to create a helper called Html.StateDropDownListFor() that does the exact same thing, except loads the drop down with all 50 US states. This way I don't have to create a SelectList for every single state drop down that I create. What is the easiest way to do this? Right now I have this:
[code]....
Am I even close? I don't want to rebuild a whole text box helper, I just want to create a helper that utilizes the existing text box helper but does the SelectList for me. That way in my views I could just do Html.StateDropDownList(x => x.State)

View 1 RepliesLocation Of HtmlHelper Instantiation For MVC?
Jan 3, 2010I am trying to debug a problem where HtmlHelper is null in extension methods. Oddly the debugger claims it's fully populated, however I consistently get null exceptions. I'm trying to figure out where HtmlHelper should being instantiated in an attempt to see where my problem may be.
Where should HtmlHelper be Instantiated?
Update: In particular I am trying to implement the extension found here, [URL] within a masterpage. The error occurs on the MVC template's HomeController.Index(). There are some 'plugins'/virtualpathing that may be causing the problem (trying to avoid this can of worms), but, code the code is essentially the same as found here: [URL]. However, I don't want to trouble anyone with the details of all of that.

I need a property Model.Something to be available in a HtmlHelper method when I call it from this view.

I do not want to explicitly pass Model.SessionKey for each helper I call.
MVC :: Override HtmlHelper.LabelFor?
Jul 1, 2010I am using VS2010 & MVC2 to develop a web app. I noticed that HtmlHelper.LabelFor doesnt contain an override that accepts either a css class or html attributes. I was thinking about writing my own override for this, but am struggling with it.
The current LabelFor method accepts a lambda expression and automatically extrapolates the property name, display name (if specified via [DisplayName] attribute and value and generates the label. How do I write my overridden to do the same, but also insert any htmlAttributes specified such as class, style etc.

JQuery :: Combining Template With HtmlHelper?
Nov 26, 2010I'm trying to create a jquery template using the HtmlHelper.ActionLink. By default it url encodes the parameters, which causes a problem for the syntax needed for the template. Is there a way to override the encoding.
In this example
<script id="itemTemplate" type="text/x-jquery-tmpl">
@Html.ActionLink("Details", "Details", new { id = "${ID}" } ) | ${Last} | ${First} <br />
</script>
the generated code for @Html.ActionLink ends up being
<a href="/User/Details/%24%7BID%7D">Details</a>
What I'd like to end up with is
<a href="/User/Details/${ID}">Details</a>
<script id="itemTemplate"
type="tex
MVC :: Bug With HtmlHelper.GenerateIdFromName Versus TagBuilder.GenerateId
Jun 29, 2010When upgrading to mvc2 i noticed some of my javascript that was keying on "Points[0]_Id" (this is invalid for an html id btw) started to fail. I pulled up the source and noticed that the TagBuilder class now generates valid client id's and replaces all invalid characters with the "IdAttributeDotReplacement" (which is a terrible name now, since it's not just a dot replacement character anymore). I started to look for a way to generate client id's using a helper built into mvc and came across HtmlHelper.GenerateIdFromName, but this still generates ids the invalid way!
TagBuilder.GenerateId( "Points[0].Id" ) = "Points_0__Id"
HtmlHelper.GenerateFromName( "Points[0].Id" ) = "Points[0]_Id"
IMO: the tagbuilder class or the GenerateFromName code should not be duplicated in two different spots or else you will get errors like this. Also I consider this change made to TagBuilder.GenerateId to be a breaking change and should be included in the breaking changes section of the release notes.
Setting Page Title From An HtmlHelper Class?
Sep 23, 2010I have an HTML Helper that essentially renders static content read from HTML files (inside of a vdir). There are cases when the HTML file has a title element defined and in such cases, the current page should use the given title. The content inside of the body should be rendered where the Helper class is referenced in the View.
This is how I call the helper.
<%=Html.StaticContent("staticcontent.htm",
new List<StaticContentTag>()
{
new StaticContentTag()
{TagKey=ReplaceTags.MarketName,
TagValue = "Austin"}
}, Model, true) %>
I'm passing in the ViewModel so that I can set the title and the last parameter is a flag that says whether to force the title or not.
The head has the title defined like this.
<title><%=Model.Title%></title>
I know what I'm doing wrong here by referencing the Model.Title element before even calling the helper. Any ideas on how I can work around this?
