I have a EditorFor HTML helper like this:
<td>#Html.EditorFor(m => m.Name, belowLevel ? disabledHtmlOptions : null)</td>
-
object disabledHtmlOptions = new { disabled = "disabled" };
I wanna make this disabled at every time. How do I do that? I dont want to do data annotations because this property is being used in other views too. Only on this view I want to disable it.
MVC 5.1 now allows passing in HTML attributes in EditorFor (see this answer). So you could do this:
#Html.EditorFor(model => m.Name, new { htmlAttributes = new { disabled = "disabled" } })
if you're stuck on using EditorFor you could set the disabled attribute via jQuery on page load. I know it's not ideal, but it's the only way unless you create an overload for EditorFor that accepts an htmlAttributes collection
$(document).ready(function() {
$('#Name').attr('disabled', 'disabled');
});
You could just render HTML for the view. If it's meant to be "read-only" just render the text. Otherwise you could render an <input> element.
For example, instead of
<td>#Html.EditorFor( m => m.Name )</td>
do
<td>#Model.Name</td>
or
<td><input type="text">#Model.Name</input></td>
I don't believe the signature of the EditorFor method allows you to specify any HTML attributes. You can if you change it to TextBoxFor however.
<td>#Html.TextBoxFor(m => m.Name, belowLevel ? disabledHtmlOptions : null)</td>

So Im currently writing a cypress test and would like to add a data-cy to checkbox's
But get an error on when im adding a data-cy="CheckBox"
#Html.CheckBoxFor(m => m.Steps, new { #class="form-check-input flex-shrink-0", #type="checkbox",name="BinComplaintRadios",#data-cy="CheckBox" })
#Html.CheckBoxFor(m => m.Steps, new { #class="form-check-input flex-shrink-0", #type="checkbox",name="BinComplaintRadios",#data_cy="CheckBox" })
Had to underscore data_cy instead of hyphenated
That is a tricky question because I want to add Html Attributes to the EditorFor() but do not want to replace the ones that was already created. Let me explain:
I have a default Editor Template for string.cshtml with the following code:
#{
var htmlAttributes = ViewData;
htmlAttributes["class"] = "text-box single-line form-control";
htmlAttributes["placeholder"] = ViewData.ModelMetadata.Watermark ?? ViewData.ModelMetadata.DisplayName;
htmlAttributes["title"] = ViewData.ModelMetadata.Watermark ?? ViewData.ModelMetadata.DisplayName;
}
#Html.TextBox("", ViewData.TemplateInfo.FormattedModelValue, htmlAttributes)
It is used to always add the following class, placeholder and title, based on the DisplayName DataAnnotation, for the Form Inputs, it is quite handy!
But the problem is that I'm having trouble adding the disable attribute for one specific Form Input with the common code:
#Html.EditorFor(x => x.Field, new { htmlAttributes = new { disabled = "" } })
When the Form Input is with a field that is not a string, it will not follow the created EditorTemplate and it will work with this exactly code, but when it is a string, the EditorTemplate replaces the Html Attributes.
Does anyone has any clue on this?
Turns out there was a few dumb errors, first of all the declaration on the EditorFor() field was wrong, the correct one is this:
#Html.EditorFor(x => x.Field, new { #disabled = "" })
The second point is to keep using the incoming htmlAttributes in the string.cshtml EditorTemplate, replacing the class property definition:
htmlAttributes["class"] = "text-box single-line form-control";
For:
htmlAttributes["class"] = htmlAttributes["class"] + "text-box single-line form-control";
In this way, the incoming html attributes is just concatenated with the new default ones.
I am using MVC4, just wondering, is it possible to update the name attribute of a html helper. I am updating this as the action method is expecting a particular name. I know I can just write raw html, but just want to know if there is an overide in the html helper
I tried this
#Html.TextAreaFor(m => m.noteDetail.NotesDetails, new { #class = "k-textbox", #cols = 100, #rows = 5, id="NotesDetails", name= "NotesDetails" })
but when I look at the generated html
<textarea class="k-textbox" cols="100" data-val="true" data-val-required="The details are required" id="NotesDetails" name="noteDetail.NotesDetails" rows="5"></textarea>
Thanks
You just need a # symbol in front of your name property.
One technique I've found when a submodel is the model that your POST action accepts is to put the HTML that renders the submodel in a partial view that's included in the main view. Have this partial by strongly typed by the submodel and pass the value of the submodel into it. This way, the prefixes won't be generated on the submodel.
#Html.Partial("_NoteDetails", Model.noteDetail)
Then in _NoteDetails.cshtml
#model NoteDetail
#Html.TextAreaFor(m => m.NoteDetails,
new { #class = "k-textbox", cols = 100, rows = 5 });
Hi I think as you pass a viewModel as it contains maybe 2 models that is why you have this name. It does like this for the Binder to construct objects from your Post or Get.
If you change the name then you will maybe perform some custom codes for your binder if you want to pass it again to the controller.
Is it possible when using Html.TextBoxFor to override the name attribute?
I have tried with no success. I need to use TextBoxFor to get client side validation to work, however for reasons I won't go into I need the name of the textbox to be different from the generated one.
I have tried the following:
#Html.TextBoxFor(x => x.Data, new { name = Model.Key + "_Data", id = Model.Key + "_Data" })
Which works for ID but not name. Is this possible?
Update: Looking into the code for TextBoxFor. It doesn't look like there is an easy way. Hopefully someone can prove me wrong.
Rob, actually there is a much simpler way. Instead of name, use Name:
#Html.TextBoxFor(x => x.Data, new { Name = Model.Key + "_Data", id = Model.Key + "_Data" })
Are you asking this because you want to apply a prefix to the name? If so, you can do this by setting ViewData.TemplateInfo.HtmlFieldPrefix in your Controller.
I learnt a lot about this stuff from Brad Wilson's blog.
EditorFor has an overload where you can supply the name attribute as a parameter:
#Html.EditorFor(expression, null, name)
Try EditorFor. you can pass string as template name if you want to make sure textbox is rendered even if property type is not string. If property is string already, it does not need templatename explicitly to render textbox, so you can pass null. Note that it does not require id parameter explicitly, it will infer it from element name. And all the validation things are still active with EditorFor
#Html.EditorFor(x => x.Data, "string", Model.Key + "_Data")
It is called Microsoft GOTCHA...
Use the name in caps, like this
#Html.TextBoxFor(m => m.Reply.Answer, new { Name = "Whatyouwant" })
ben's answer got me what I was looking for except you need to wrap in in Html.Raw
#Html.Raw(Html.TextBoxFor(x => x.Data).ToString().Replace("Data", "NewData"))
a little bit "unpretty"=), try:
#Html.TextBoxFor(x => x.Data).ToString().Replace("Data", "NewData")
For me, it works! I hope that help!
#Html.EditorFor(model => model.Nome, new { htmlAttributes = new { #class = "form-control", #maxlength = "80", #id = "NomeFilter", #Name = "NomeFilter" } })
#Html.EditorFor(Model => Model.Something, "name", "name", new {#class = "form-control" })
Not sure which of those two string parameters in the middle do the work, but it worked only when I typed both of them.
For this example, I was disabling form fields based on permissions, but still showing them. I had a hidden field to send the value to the controller, but wanted a different field name in the EditorFor.
First param after model value represents the "name" property, second is the new name.
#Html.EditorFor(m => m.UserName, "name", "UserNameDisabled", new { htmlAttributes = new { #class = "form-control", #disabled = "disabled"} });
Results in:
<input class="form-control text-box single-line" disabled="disabled" id="UserNameDisabled" name="UserNameDisabled" type="text" value="someEnteredValue" />
Keep it simple, your already providing the ID you should simply be able to use the method "TextBox" instead of "TextBoxFor" and it will work fine client side and server side. In addition, although the accepted answer will work but will produce duplicate Name attributes on your tag if you inspect it using a browser. The below solution does not have that problem.
MvcHtmlString Html.TextBox(string name, string value, object htmlAttributes)
#Html.TextBox(Model.Key + "_Data", Model.Key, new { id = Model.Key + "_Data" }
I am kind of stumped because, I want to format the value and add a html attribute for css class.
If I use #Html.TextBoxFor(m => m.DateModified)
- I can add html attribute but formatting does not work via DisplayFormat attribute on the member.
If I use #Html.EditorFor(m => m.DateModified)
- Formatting works but I cannot add html attribute
If I use #Html.TextBox("DateModified", Model.DateModified, ...)
- I get null reference exception when Model is null when the form is in add mode
What is the best way to achieve this?
I ended up solving this by creating a custom editor template for my date picker as so:
Shared/EditorTemplates/DateTime.cshtml
#model System.DateTime?
#Html.TextBox("", Model.HasValue ? Model.Value.ToString("dd/MM/yyyy") : string.Empty, new { #class = "date-picker" })
Then in my original page continue to use
#Html.EditorFor(m => m.DateModified)
You could...
#Html.TextBoxFor(m => m.DateModified, new { Value = Model.DateModified.ToString("MM-dd-yyyy"), #class = "superCoolClassName"})
Use #Html.EditorFor(m => m.DateModified), because otherwise the DisplayFormat attribute will have no effect.
To add further attributes like a CSS class, you have to create an editor template for the DateTime.
Create a file EditorTemplates/DateTime.cshtml with the following content:
#Html.TextBox("", ViewData.TemplateInfo.FormattedModelValue, new
{
#class="date"
})
Please note that the value of the TextBox is not set with the Model directly, but rather with the TemplateInfo.FormattedModelValue, because that value will be formatted according to the DisplayFormat attribute while the Model not. (This took me quite some time to realize. :))
In simple cases this might be enough, e.g. if the CSS class can be the same for all date editors.
If you want to parametrize the attribute, you can do that as well, passing the attribute value parameter to the EditorFor.
#Html.EditorFor(m => m.DateModified, new { #class = "someClass" })
However, this parameter will be not automagically delegated to the HTML control as attribute, but you have to "handle it" in the template explicitly. According to my experiences you can access this parameter value in the ViewData in the template, so the parametrized template looks like this:
#Html.TextBox("", ViewData.TemplateInfo.FormattedModelValue, new
{
#class=ViewData["class"]
})
To prevent hardcoding the key/value pairs listed in EditorFor , convert the ViewData object to a Dictionary and pass that dictionary object to TextBox.
eg
#Html.EditorFor(m => m.DateModified, "Template", new { #class = "someClass", size=8 , htmlTag="custom" })
And in the template you have
#Html.TextBox("", ViewData.TemplateInfo.FormattedModelValue, ViewData.ToDictionary(c=>c.Key,c=>.Value))
To show json date in textbox (cshtml):
var d1 = ui.item.IssueDate;
var d = new Date(parseInt(d1.slice(6, -2)));
var Issdate = ("0" + (d.getMonth() + 1)).slice(-2) + '/' +
("0" + d.getDate()).slice(-2) + '/' +
d.getFullYear().toString();
$('#IssueDate').val(Issdate);
