I'm using ASP.NET MVC 3 right now with unobtrusive jquery client validation. By default, ValidationMessageFor generates a span tag with certain classes and attributes set. I would like it to generate a different template instead. For example, I might want a div tag with a certain background image.Is this possible at all, or can I just obtain the plain text error message from there so I can do my own styling?

Using Visual Studio 2008, I need to create a custom web form that when picked acts like the web content form, by providing a dialog that lets you pick a master page. I have looked through the webform.zip template and thought I had a clue, but trying different combinations has baffled me as it either doesn't appear or doesn't work.
Also when you set the project type to Web and sub project type to CSharp it doesn't appear, so I don't know if this part of the cause, because I would of hoped that the SupportsMasterPage element would of caused this dialog to appear, if it is a web item, but no luck. Frown
p.s. I have used my googling resources to the maximum so unsure what to do.
I'm using DataAnnotations in my viewmodel class:
[Code]....
In my view I enabled client-side validation.
[Code]....
So, is this the way it's supposed to work? Shouldn't enabling client-side validation highlight non-validating elements by default, without an needing to create an associated Html.ValidationMessageFor(), if it has a DataAnnotation validation attribute?
I was working on migrating MVC1 app to MVC2 today and i have come across a problem while changing the ValidationMessage to ValidationMessageFor implementation.

Is this somewhat a bug in "ValidationMessageFor"
I am looking on Music store example:
In Model we have:
[Required(ErrorMessage = "An Album Title is required")]
public string Title { get; set; }
In a View we have a Razor code:
<div class="editor-field">
@Html.EditorFor(model => model.Title)
@Html.ValidationMessageFor(model => model.Title)
</div>
My questions: Where I can find definition of EditorFor and ValidationMessageFor helpers?
What is the meaning of "=>" in the above command?
I'm trying to write a custom rendering template for use in the DisplayForm of a list whose fields include Title, HeaderImageUrl, Body. I've got the following so far:
<SharePoint:RenderingTemplate ID="NewsListForm" runat="server">
<Template>
<h1><SharePoint:FieldValue FieldName="Title" runat="server"/></h1>
<div>
<p>
<SharePoint:UrlField FieldName="HeaderImageUrl" runat="server"></SharePoint:UrlField>
<SharePoint:RichTextField FieldName="Body" runat="server" />
</p>
</div>
</Template>
</SharePoint:RenderingTemplate>
The HeaderImageUrl field is configured to be an Image URL, but when I use the UrlField control, it renders a link.
I was thinking there might be a way to grab field values and put them in attributes, so something like this:
<asp:Image ImageUrl="<% FieldValue["HeaderImageUrl"] %>" runat="server"/>
If this kind of thing isn't possible, then is there another control in Microsoft.SharePoint.WebControls that would render an image from a URL?
For example:
<uc:AdmiralAckbar runat="server" id="myCustomControl">
<Warning SomeAttribute="It's A Trap">
My Data
</Warning>
</uc:AdmiralAckbar>
I'm not sure how to add SomeAttribute.
Code without the attribute is:

I'm working on a custom navigation menu, I've added the following property within my MenuItem class to allow users add them controls into it.
View 1 RepliesI've created a class which extends System.Web.Mvc.ViewPage which I want to be the default class each view inherits from. This is controlled by the "pageBaseType" attribute in the "pages" element in the web.config file in each Views folder. If I add a Views folder in Visual Studio, it creates the web.config.
I would like to change the template it uses to do this to use a different value for pagBaseType. I assume there is a template somewhere I could modify, but I don't know where it is.
Let's say I have a property and a textbox on a view
[Code]....
I don't understand why each time I use the modelbinding validation like this
[Code]....
I still get the error displayed, But this time only by Html.ValidateSummary(). the textbox is not highlighted anymore and Html.ValidateMessageFor() doesn't display any message at all.
Is there something I should do the solve this problem? It's important because I have many form that user need to fill out. It's important to highlight the textbox to make it obvious to them.
found a way to get their validation messages to show as a tooltip instead of inline WITHOUT reinventing all validation framework over again?
View 6 RepliesI'm trying to have an asp.net custom control with a field like:
<ErrorTemplate>
<h1>Error</h1>
<p>Blue wizard shot the food</p>
</ErrorTemplate>
What I want to end up with is:
<h1>Error</h1><p>Blue wizard shot the food</p> in a string in my codebehind.
At the moment, the process I use to get this data out of the template is:
First this gets instantiated into a placeholder by my code:
ErrorTemplate.InstantiateIn(errorPHolder);
which is an asp.net placeholder control - it has to be instantiated into something which can support controls.
What I then want to do is add this to my page using JQuery and a variable, like this:
string script = "var Errortemplate = " + errorPHolder.ToString() + ";";
scriptmanager.register(script); // pseudocode
so the result would be, on my page:
var Errortemplate = '<h1>Error</h1><p>Blue wizard shot the food</p>';
Then I can use JQuery to do someDiv.html(Errortemplate);
Finally resulting in whatever they put in <ErrorTemplate> appearing on the page
Because I'm using JQuery it might be possible to do this a different way, such as adding the placeholder to the page into a hidden div and using JQuery to copy the values out.

View 3 RepliesI've got a custom Editor Template that is essentially:
<div id="control">
<%: Html.DropDownListFor(model => model.Day, Model.Days)%>
<%: Html.DropDownListFor(model => model.Month, Model.Months)%>
<%: Html.DropDownListFor(model => model.Year, Model.Years)%>
</div>
Whilst my validation is successful/fine with this control (ValidationMessageFor works) I have been unable to find how to highlight the control when validation fails (e.g. with a TextBoxFor the textbox border goes red if validation fails)
Does anyone know how I can add this behaviour with a custom editor template?

I want my User Control to be able to have Literal Content inside of it. For Example:

Currently the code for my user control is:

Partial Public Class ctrFormText
Inherits UserControl
[code]...
i create a custom control which can hold some templates, such as Header, Body Footer, etc.
[Code]....
i tried to use smarttags to allow the user to edit each of the templates, which worked pretty well. what i could not get working was to add a template if it has not been in the control. eg. add a header-template to the control above. i tried using the RootDesigner.AddControlToDocument() function of my controldesigner. but this function gives me an error, telling me the control i'm going to add the template (i used a new HtmlGenericControl("HeaderTemplate") as new Control) to is not valid. (i can't give the exact error message, cause i use a german version of visual studio 2008) i've been searching the web for nearly half a day now, but i did'nt find a working solution for my problem.
I have a GridView with custom pager template. I use SqlDataSource with a dynamically generated select query.
To make application faster, I want to select not all records, but as many as fit in a GridView page. But in this case, the pager section doesn't show up. Could anybody suggest how I can fix that? Some people say I should do my own pager template, but I don't know neither how to make it, nor how to use it.
I saw some CustomControls using a separated ascx file, it rendered the ascx file (the template) but all the code was in a dll (the control).How can I do that? Can someone post a Hello World example?

First and foremost ... I already made a few changes in the template, the most important one changing the methods generated for stored procedures with OUTPUT parameters and no resultset so that instead of instantiating a few OutputParameter objects, passing them to the method and extracting the values (all without any type checking) you just call the method with a few "out someType?" parameters so I do not need the very basics. I am totally confused by all those GlobalItem, EdmProperty,BuiltInTypeKind, TypeUsage and all this made of objects, all alike and all different though so as soon as I need more data than what's already used by the template I run into problems :-(What I would like is to change the WritePrimitiveTypeProperty() so that it outputs [StringLength(xxx)] for all char, varchar, nchar and nvarchar properties. But I can't find a way to get from an EdmProperty in the model to the database type in the store.anyone is interested here's the modified stored procedure mapping code for the template. The first code replaces the original in the .tt:
[Code]....
the second needs to be added into a copy of EF.Utility.CS.ttinclude that you add to your project and reference from the .tt
