MVC :: Some Model Metadata Attributes Don't Seem To Work With Html.EditorForModel ()

Apr 5, 2010

i am working an asp.net mvc 2 web app using model metadata and some of the model metadata don't seem to work when using the default Html.EditorForModel().For example, when applying the DefaultValue(1) and the ReadOnly(true) attributes on a model field, the field displayed on edit view has zero for its default value and it is not read only.

MVC Html.textbox - How To Validate Numbers Only

Apr 12, 2010

With the HTML helper, how would you enforce number only without submitting? I know it was done with regular expression if you had a textbox in classic ASP.NET

<%=Html.TextBox("txtYearOfWork",String.Empty, new { maxlength = 4, size="5", autocomplete = "off" }) %>

MVC :: Bug In EditorForModel W/ EditorFor Rendering?

Jan 18, 2010

I am learning MVC using the v2 release with Entity Framework v4. Let's say I have 3 objects Game, Points and Players. They are related in the following manner:Game has points and the Points can have a player associated with them ( 1 Game to many Points and a Point object can have one Player).

I am attempting to use the EditTemplates feature in MVC2 to render my views. In my Game Edit view I want to have the basic Game object information editable, and also the related Points objects. Currently I am utilizing "`<%= Html.EditorForModel() %>`"(Which seems pretty slow) to render the Edit View and then I have a specific Game and Point EditTemplates.

The data renders correctly and is editable for both the Game and Point information. When I go to perform the update and submit the form I receive the "Game" object in my Update ActionResult. The basic properties are populated for the Game object but any deep properties such as Points are not; they appear as null. If I look at the Request.Form variables in debug I can see the Points fields are being passed to the server but do not place themselves back into the Game object.

In my Game EditTemplate I am using the following to render the Points objects:

<%= Html.EditorFor(c => c.Points) %>

My Points EditTemplate looks like: [code]...

why this is rendering as "Points.Points[index] instead of Points[index]? I tried messing with the parameters in the EditFor:

<%= Html.EditorFor(c => c.Points,null,"Points") %>

but then the inputs render as Points.Points[index]

MVC :: Use DisplayForModel And EditorForModel With A Collection?

May 26, 2010

How can I use DisplayForModel in a loop with a View for which I've passed a collection of objects? That is, within the loop I want to call DisplayForModel each time for the specific object (not the collection). Or does MVC not currently support this?

So I'll like to be able to do something like in the below, but this itself doesn't work.

MVC :: Show/Hide Fields In EditorForModel

Jul 2, 2010

I've been tinkering with the Nerddinner tutorial (upgraded to the new MVC 2.0 version actually) and I am trying to figure out how to dynamically hide/show fields in the EditorForModel template.I have added a new field to the model and a dropdown list for it in the editor, and I would like to be able to toggle the visibility on a couple of textboxes if a user selects a particular value from the dropdown list.

I did manage to access/manipulate the values of the textboxes using javascript (by altering the "onblur" example in the tutorial app), but couldn't figure out how to access the properties of them.

To Get The EditorForModel / Want To Use A SelectList Instead Of A TextBox For Status?

Jul 1, 2010

I have written an Enum extension method that allows me to create a view model and allows me to easily bind a generic Enum to a SelctList like:this.ProductStatusList = new ProductStatusTypes().BindToSelectList<ProductStatusTypes>
(product.Status.ToString());

In my View I can then have:

<% using (Html.BeginForm()) {%>
<fieldset> [code]...

Notice I am using EditorForModel and then a seperate DropDownList. My question is: Is there a way to get the EditorForModel to be clever enough to pick up that I want to use a SelectList instead of a TextBox for status?

JQuery Validate Plugin MS MVC Won't Validate?

Oct 25, 2010

I'm trying out the jQuery Validation plugin jQuery Docs Here is the markup of my form:

<% using (Html.BeginForm("action", "contoller", null, FormMethod.Post, new { id = "sxform" })){%>
<div id="manifest">
Manifest Option:<br />
<%= Html.DropDownList("docid", ViewData["manifests"] as SelectList, new { @class = "required" })%>
</div>
<div id="release">
Release Version:<br />
<%= Html.TextBox("release", null, new { @class = "required" })%>
</div>
<div id="locale">
Localization:<br />
<%= Html.DropDownList("localization", ViewData["localizations"] as SelectList, new { @class = "required" })%>
</div>
<div id="label">
Label:<br />
<%= Html.TextBox("label", null, new { @class = "required" })%>
</div>
<div id="session">
Session ID (optional):<br />
<%= Html.TextBox("sessionInput", null, new { @class = "required" })%>
</div>
<div id="submit"><input type="submit" value="Build" /></div>
<% } %>
JS:
$(document).ready(function(){
$("#sxform").validate();
});

I am using MS MVC HTML Helpers to render this form. The resulting markup looks fine. IE each input and selection element contains the attribute 'class' with the value 'required'. When I submit this form the validation does noting.

C# - Auto Generate Javascript To Update Client Html Compared To Previous Html?

Jan 16, 2010

do you think it would be difficult to write a framework where mvc compares last html it output to the current html we want to output, and instead of sending the entire html, figure out what has changed and generate js code that will do the updating as compared to previous html? (presuming nothing was manually changed on the client using js).

Forms Data Controls :: Repeater ItemTemplate - If Eval(field)=0 Then HTML Else HTML

Feb 20, 2010

The following seems reasonable, but it returns an error:

<asp:Repeater ID="RepeaterF" runat="server" DataSourceID="DSF" >
<ItemTemplate>
<%
If Eval("Item_Batch") = 0 Then
%><tr><td></td><td colspan="2"></td><td></td></tr><%
Else %>........

Error: "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."

I am finding it difficult to accept that the whole Repeater approach has any benefits over just creating a loop in code, iterating through a recordset, and building a html table into a variable, then dumping it to the page. This repeater is spawning pages of code and objects, and surely this is all using up server resources.

C# - Pass Model Values As Javascript Function Parameters From Inside Mvc Html Helper Such A Html.Radio?

Jul 20, 2010

I think I need to drop in some escape characters, but I'm not quite sure where. Here is the javascript function I'm attempting to call:

function setData(associateValue, reviewDateValue) {
var associate = document.getElementById("Associate");
var reviewDate = document.getElementById("ReviewDate");
associate.value = associateValue;
reviewDate.value = reviewDateValue;
}

Here is the asp .net mvc line where I'm attempting to create a Radio button with a click event that calls the above function and passes data from the model as javascript parameter values.

<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('<%=item.Associate%>','<%=item.ReviewDate%>' )" } )%>

The above throws a bunch of compile issues and doesn't work. A call such as the following does call the javascript, but doesn't get the data from the model.

<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('item.Associate','item.ReviewDate' )" } )%>
<%= Html.RadioButton("Selected", item.Selected, new { onClick="setData('item.Associate','item.ReviewDate' )" } )%>
<% String functionCall = String.Format("setData('{0}','{1}')", Html.Encode(item.Associate), Html.Encode(item.ReviewDate )) ; %>
<%= Html.RadioButton("Selected", item.Selected, new { onClick=functionCall } )%>
