I am building this FormControls widget and have added some controls like sf-html-field and sf-image-field. I am at the point where I want to add the Choices and not sure how best to do that. I want to it work the same way the built-in MultipleChoiceField control work.
DesignerView.Simple
<form>
<div class="form-group">
<label for="heading-text">Label (Question)</label>
<sf-html-field class="kendo-content-block"
sf-model="properties.Question.PropertyValue">
</sf-html-field>
</div>
<div class="form-group">
<label for="image-field" class="m-top-sm">#Html.Resource("Image")</label>
<sf-image-field class="sf-Media--info modal-settings modal-settings-space"
sf-model="properties.ImageId.PropertyValue"
sf-image="selectedImage"
sf-provider="properties.ImageProviderName.PropertyValue"
sf-media-settings="#SettingsHelpers.GetMediaSettings("Image")"
id="image-field">
</sf-image-field>
</div>
<div class="form-group">
<label for="heading-text">Choices</label>
</div>
</form>

public IFormFile UploadedImage { get; set; }
<div class="form-group row">
<label asp-for="UploadedImage" class="ml-2">Image</label>
<input asp-for="UploadedImage" class="form-control" type="file"/>
<span asp-validation-for="UploadedImage" class="text-danger"></span>
</div>
Currently user can upload anything, which will lead to awful things in backend.
Is there any easy straightforward way to allow uploading only images? Looking online some solutions look absolutely terrifying, but they are 5+ years old, so maybe .NET got better way to do it.
Like [Image] attribute or something.
You can try to use accept attribute.
Here is a demo:
View:
<div class="form-group row">
<label asp-for="UploadedImage" class="ml-2">Image</label>
<input asp-for="UploadedImage" class="form-control" type="file" accept="image/png, image/jpeg, image/gif"/>
<span asp-validation-for="UploadedImage" class="text-danger"></span>
</div>
When you click choose file,you can only see and select with .png,.jpeg,.gif type file.
Here is my files:
And when I click choose files:
I'm trying to add an input-addon to a form input using Bootstrap 3 but it doesn't display the errros correctly. This is my html code:
<label for="inputEmail3" class="col-sm-2 control-label">Email</label>
<div class="input-group">
<input type="text" id="addTax_rate" class="form-control">
<span class="input-group-addon">%</span>
</div>
The input group displays correctly without errors, but when I add the has-errors class to it, it comes to this:
What am I doing wrong? Thanks
I am working on an ASP.NET MVC 4 Project. I want to style data validation errors on my login page with Bootstrap 3.0. When I debug the page and it gives data validation errors, this codes are disappeared in source of my login form:
<form action="/Account/Login" class="col-md-4 col-md-offset-4 form-horizontal well" method="post"><input name="__RequestVerificationToken" type="hidden" value="Zbg4kEVwyQf87IWj_L4alhiHBIpoWRCJ9mRWXF6syGH4ehg9idjJCqRrQTMGjONnywMGJhMFmGCQWWvBbMdmGFSUPqXpx6XaS4YfpnbFm8U1" /><div class="validation-summary-errors"><ul><li>The user name or password provided is incorrect.</li>
</ul></div> <div class="form-group control-group">
<div class="col-md-6 col-md-offset-3">
<input class="input-validation-error form-control" data-val="true" data-val-required="User name alanı gereklidir." id="UserName" name="UserName" placeholder="Kullanıcı Adı" type="text" value="" />
<span class="field-validation-error" data-valmsg-for="UserName" data-valmsg-replace="true">User name alanı gereklidir.</span>
</div>
</div>
<div class="form-group">
<div class="col-md-6 col-md-offset-3">
<input class="input-validation-error form-control" data-val="true" data-val-required="Password alanı gereklidir." id="Password" name="Password" placeholder="Şifre" type="password" />
<span class="field-validation-error" data-valmsg-for="Password" data-valmsg-replace="true">Password alanı gereklidir.</span>
</div>
</div>
<div class="form-group">
<div class="col-md-4 col-md-offset-4">
<button class="btn btn-default" type="submit">Giriş Yap</button>
</div>
</div>
</form>
How can I style these errors like "for=inputError" property of label with Bootstrap 3?
As it's shown in Bootstrap's docs, you need to apply class has-error to the div that contains the input and has class form-group:
<div class="form-group has-error">
...
</div>
It's a quite ugly to write a condition for each property you want to check and apply class has-error depending on the results of that condition, though you can do it like so:
<div class="form-group #(Html.ViewData.ModelState.IsValidField(Html.IdFor(x => x.UserName)) ? null : "has-error" )">
This takes care of the server side validation. However, there is also client side validation you need to think about. For that you'd need to write some jQuery that would check for existence of class field-validation-error and apply class has-error depending on the result.
You may do it all your self, though I suggest checking out TwitterBootstrapMVC which does all of that automatically for you. All you'd have to write is:
#Html.Bootstrap().FormGroup().TextBoxFor(m => m.UserName)
Disclaimer: I'm the author of TwitterBootstrapMVC. Using it in Bootstrap 2 is free. For Bootstrap 3 it requires a paid license.
Can I debug the below mentioned code on *.cshtml file ? I have used knockout js as my client side java script library.
<div data-bind="ifnot: book()">
<div>
<h2>Add New Book</h2>
</div>
<div>
<label for="name">Name</label>
<input data-bind="value: $root.Name" type="text" title="Name" />
</div>
<div>
<label for="publisher">Publisher</label>
<input data-bind="value: $root.Publisher" type="text" title="Publisher" />
</div>
<div>
<label for="price">Price</label>
<input data-bind="value: $root.Price" type="text" title="Price" />
</div>
<br />
<div>
<button data-bind="click: $root.create">Save</button>
<button data-bind="click: $root.reset">Reset</button>
</div>
</div>
On above code I need to check the values of say "book() or $root.Name ,etc".Can I do that ?
UPDATE:On Fire bug
You'll need to use client side debugging. Either use a developer toolbar (opened with F12 in most browsers) or use Visual Studio Client Script debugging.
After the #nemesv link I did small R&D about this.Below I have mentioned the way you can find the KO binding values of the DOM elements.Hope this will help someone in future.

I'm using MVC4 but I imagine this is an issue for anyone using the new Bootstrap 3 version. Since form-control is now width:100% by default, what is the best practice for placing validation messages?
In version 2.x, placing the validation messages in the help-inline span just after the input control worked best to ensure that the message was placed to the right of the control.
But in version 3, they always get pushed to the bottom making all the controls shift down because the validation messages are forced under the control.
<div class="form-group has-error">
<label for="Label" class="col-lg-2 control-label">Label</label>
<div class="col-lg-5">
<input class="form-control input-validation-error" data-val="true" data-val-required="Required" id="Label" name="Label" type="text" value="">
<span class="help-inline"><span class="field-validation-error" data-valmsg-for="Label" data-valmsg-replace="true"><span for="Label" generated="true" class="">Required</span></span></span>
</div>
</div>
I've considered manually setting them on a new column like this (below) but wondering if there was a more acceptable way or a less manual way of dealing with this.
<div class="form-group has-error">
<label for="Label" class="col-lg-2 control-label">Label</label>
<div class="col-lg-5">
<input class="form-control input-validation-error" data-val="true" data-val-required="Required" id="Label" name="Label" type="text" value="">
</div>
<div class="col-lg-5">
<p class="form-control-static"><span class="field-validation-error" data-valmsg-for="Label" data-valmsg-replace="true"><span for="Label" generated="true" class="">Required</span></span></p>
</div>
</div>
I wouldn't say there are "best practices" for presenting form validation errors. It's more of a personal design choice.
Depending on how much JS you want to write, you could get a little slick and insert an input group addon which holds an error message in a tooltip icon, like so...
<div class="input-group">
<input type="text" class="form-control">
<span class="input-group-addon">
<i data-toggle="tooltip" title="Error msg here" data-container="body" class="glyphicon glyphicon-question-sign"></i>
</span>
</div>
Honestly though, I think messages appearing below input fields are fine, as long as they don't disturb page layout and push content down when they appear. (Which is just a matter of having a container that displays block and has a a hard-coded height.)
