Im beginner in the ASP.NET MVC. I am add drop down menu , but the CSS does not work correctly. How can I fix it? This is my code:
#Html.DropDownListFor(m => Model.Fields[i], new SelectList(Model.attrs[i].atributeDetails, "AtributeDetailId", "AtDetailVal", int.Parse(Model.Fields[i])), " ", new { Class = "form-control", disabled = "disabled",style = "width:575px;height:25px;font-size:small;" })
If you're saying that the styles associated with the 'form-control' class aren't working then it could be because the 'Class' word needs to be lowercase. I normally use #class="my-class". So maybe try the following:
#Html.DropDownListFor(m => Model.Fields[i], new SelectList(Model.attrs[i].atributeDetails, "AtributeDetailId", "AtDetailVal", int.Parse(Model.Fields[i])), " ", new { #class = "form-control", disabled = "disabled",style = "width:575px;height:25px;font-size:small;" })

Hopefully this is an easy one...
I am having an issue with Bootstrap 5 floating labels not working when I create HTML elements using Razor syntax.
If I use plain HTML they work as expected. Using razor the labels are appearing in the state you'd expect if the text box has focus (top left of input)
<div class="form-floating mb-3">
#Html.EditorFor(model => model.Recipient, new { htmlAttributes = new { #class = "form-control", #onchange = "javascript: Changed( this, 'recipient-name' );" } })
#Html.ValidationMessageFor(model => model.Recipient, "", new { #class = "text-danger" })
#Html.LabelFor(model => model.Recipient)
</div>
Here is an image of the above on load -
Code output in UI
Has anyone had this issue, know a way to get around it or spot what I am doing wrong? (I need the input tag to be populated from the model as the form can be used to create a new request or update and existing request)
Thanks
Do you want something like below?
<div class="form-floating">
<input asp-for="Recipient" class="form-control" />
<label asp-for="Recipient"></label>
<span asp-validation-for="Recipient" class="text-danger"></span>
</div>
Thanks but I figured out what I was doing wrong. The issue was simple...
ISSUE - There was no placeholder tag which this animation relies on.
RESOLUTION - Add #placeholder = "Recipient Name"
To provide a bit more info the text input looks different when in focus/not focused. This was the issue.
It should have looked like this when not focused - Not Focused
But it was looking like this - Focused
The code that fixed the issue is
<div class="form-floating mb-3">
#Html.EditorFor(model => model.Recipient, new { htmlAttributes = new { #class = "form-control", #onchange = "javascript: Changed( this, 'recipient-name' );", #placeholder = "Recipient Name" } })
#Html.ValidationMessageFor(model => model.Recipient, "", new { #class = "text-danger" })
#Html.LabelFor(model => model.Recipient)
</div>
I am using MVC 4, jQuery and Bootstrap plugin but I want to off the suggestion words, so I put autocomplte="off" but it is not working. Please suggestion me
My razor code is
#Html.TextBoxFor(m => m.Customer_Username, new { id = "logusrname",#autocomplete="off", #class = "form-control", #role = "form", #placeholder = "Username" })
I have three dropdownlistfor in a loop that do not show the correct value from the DB. They always default to the first entry. I have checked and double checked the DB and verified that it should be the second one in the list. The list is also created correctly. What am I missing?
#foreach (CustomerMeasurementProfile oProfile in Model.Customer.CustomerMeasurementProfiles.Where(m => m.DeletedDate == null))
{
<div class="valuesforoneprofile form-group form-group-tight col-md-2">
<div class="col-md-11" >
#Html.Hidden(string.Format("Customer.CustomerMeasurementProfiles[{0}].Id", i), oProfile.Id)
#Html.Hidden(string.Format("Customer.CustomerMeasurementProfiles[{0}].CustomerId", i), oProfile.CustomerId)
#Html.TextBox(string.Format("Customer.CustomerMeasurementProfiles[{0}].Name", i), oProfile.Name, new { #class = "form-control input-sm" })
</div>
<div class="col-md-11" style="text-align:center">
#Html.CheckBox(string.Format("DeleteProfiles[{0}]", i), Model.DeleteProfiles[i])
</div>
<div class="col-md-11" style="padding-top:4px;">
#Html.DropDownListFor(m => oProfile.BodyTypeShoulderId, new SelectList(Model.BodyTypeShoulders, "Id", "Name"), new { #class = "form-control input-sm-select" })
</div>
<div class="col-md-11" style="padding-top:4px;">
#Html.DropDownListFor(m => oProfile.BodyTypePostureId, new SelectList(Model.BodyTypePosture, "Id", "Name"), new { #class = "form-control input-sm-select" })
</div>
<div class="col-md-11" style="padding-top:4px;">
#Html.DropDownListFor(m => oProfile.BodyTypeChestId, new SelectList(Model.BodyTypeChest, "Id", "Name"), new { #class = "form-control input-sm-select" })
</div>
If you want to set the selected value that is coming in Model. You need to do it like this:
#Html.DropDownListFor(m => oProfile.BodyTypeShoulderId,
new SelectList(Model.BodyTypeShoulders,
"Id",
"Name",
oProfile.BodyTypeShoulderId),
new { #class = "form-control input-sm-select" })
The above code will set the dropdown selected value to whatever is in the current Model object BodyTypeShoulderId
The first argument of DropDownListFor tells that on form post drop down selected value will be mapped with the Model property which is set there (we are passing m => oProfile.BodyTypeShoulderId) but this not sets selected Value.
For setting selected value you have to pass SelectList fourth parameter using this overload of SelectList class which is object selectedValue
Unfortunately #Html.DropDownListFor() behaves a little differently than other helpers when rendering controls in a loop. For a single object
#Html.DropDownListFor(m => oProfile.BodyTypeShoulderId, new SelectList(Model.BodyTypeShoulders, "Id", "Name"))
would work fine (if the value of BodyTypeShoulderId matches the value of one of the options, then that option would be selected). Ehsan has shown a work around when using it in a loop, however you have a few other issues in you code, not the least is that many of your properties will not post back correctly to a collection because your using a foreach loop rather than a for loop (which is generating duplicate name and id attributes). Your also generating a new SelectList in each iteration of the loop which is not very efficient.
You can solve both these and the dropdown selection issue by using an EditorTemplate. Assuming property CustomerMeasurementProfiles is typeof CustomerMeasurementProfiles, then
CustomerMeasurementProfiles.cshtml (add this to Views/Shared/EditorTemplates or Views/YourController/EditorTemplates)
#model CustomerMeasurementProfiles
#Html.HiddenFor(m => m.ID)
#Html.HiddenFor(m => m.CustomerId)
....
#Html.DropDownListFor(m => m.BodyTypeShoulderId, (SelectList)ViewData["shoulders"])
....
In the view model, add properties for the SelectList's and filtered collection of the items to display
IEnumerable<CustomerMeasurementProfiles> ActiveCustomerMeasurementProfiles { get; set; }
public SelectList BodyTypeShoulderList { get; set; }
....
and assign those values in the controller
Then in the main view
#using (Html.BeginForm())
{
...
#Html.EditorFor(m => m.ActiveCustomerMeasurementProfiles, new { shoulders = Model.BodyTypeShoulderList })
...
Using #Html.EditorFor() with a collection will correctly name the controls (and correctly select the right options) and on post back, ActiveCustomerMeasurementProfiles will now be correctly populated with all its properties.
On the edit screen I am allowing the user to edit a record.
But I dont want them to edit the lastUseDate. How can I set it to read only, instead of EditorFor LastUseDate, disabled?
#Html.EditorFor(x => x.Device.LastUseDate)
<%= #Html.TextBoxFor(x => x.Device.LastUseDate, new { #readonly = "readonly", disabled = "disabled", }) %>
Try this:
#Html.EditorFor(x => x.Device.LastUseDate, new { disabled = "disabled", #readonly = "readonly" })
It'll add disabled and readonly attribute to your textbox.
Instead of have "disabled="true"" hardcoded in the TextBoxFor element, I want it pulled from the Model. The model property (Model.InvoicedApprovedBy) would be set to "" (enabled) or "disabled="disabled" (disabled)
<%= Html.TextBoxFor(m => m.WorkingModel.Detail.ApprovedBy, new { id = "InvoiceApprovedBy", disabled="true", style = "width: 203px; " })%>
I want to do something like this:
<%= Html.TextBoxFor(m => m.WorkingModel.Detail.ApprovedBy, new { id = "InvoiceApprovedBy", Model.InvoicedApprovedBy, style = "width: 203px; " })%>
It sets a html attribute called "InvoicedApprovedBy" instead of just placing the string "disabled="disabled"" into it. How to I get it to place the string?
<%= Html.TextBoxFor(m => m.WorkingModel.Detail.ApprovedBy, new { id = "InvoiceApprovedBy", disabled = Model.InvoicedApprovedBy, style = "width: 203px; " })%>
You won't need to set the model property to "disabled=disabled", just "disabled".
