we would need to see your form to ascertain what you are passing back, you should add id, UserName, guiid etc as hidden fields on your form

Into using there is a table with:

<td>
@if (!string.IsNullOrWhiteSpace(profileModel.UserName))
{
<div class="mb-3">
<label asp-for="@profileModel.UserName" class="form-label"></label><br>
<input asp-for="@profileModel.UserName" class="form-control" aria-required="true" disabled/>
<span asp-validation-for="@profileModel.UserName" class="form-text text-danger"></span>
</div>
}
</td>

The input it's disable only for the front-end edit.

For the exemple this value, will arrive like empty.

So, you mean add all values and some all this like: guiid, username must be hidden?

How are you initializing your model?

Are you doing something like

                // Build a profile model to edit
                ProfileModel = await _memberModelBuilderFactory
                    .CreateProfileModel()
                    // If null or not set, this will redirect to the current page
                    .WithRedirectUrl(null)
                    // Include editable custom properties on the form
                    .WithCustomProperties(true)
                    .BuildForCurrentMemberAsync()

Yes, in this way:

 // Build a profile model to edit
    var profileModel = await memberModelBuilderFactory
        .CreateProfileModel()
        // If null or not set, this will redirect to the current page
        .WithRedirectUrl(null)
        // Include editable custom properties on the form
        .WithCustomProperties(true)
        .BuildForCurrentMemberAsync();

what usings/model import do you have in your view? could be you should be doing

@Model.UserName

@inherits Umbraco.Cms.Web.Common.Macros.PartialViewMacroPage    
@using Umbraco.Cms.Core.Services
@using Umbraco.Cms.Web.Common.Security
@using Umbraco.Cms.Web.Website.Controllers
@using Umbraco.Cms.Web.Website.Models
@using Umbraco.Extensions
@inject MemberModelBuilderFactory memberModelBuilderFactory;
@inject IMemberExternalLoginProviders memberExternalLoginProviders
@inject IExternalLoginWithKeyService externalLoginWithKeyService
@{

    // Build a profile model to edit
    var profileModel = await memberModelBuilderFactory
        .CreateProfileModel()
        // If null or not set, this will redirect to the current page
        .WithRedirectUrl(null)
        // Include editable custom properties on the form
        .WithCustomProperties(true)
        .BuildForCurrentMemberAsync();

    var success = TempData["FormSuccess"] != null;
}

I use "profileModel" to bind properties with input tag. If i used "@Model.Username" for the exemple, the Model is a current page.

Being new to Umbraco, I still need to understand its logic well... so I created a custom controller to check what happens... In my controller I removed the prefix : Before

public async Task<IActionResult> HandleUpdateProfile([Bind(Prefix = "profileModel")] ProfileModel model)

After

public async Task<IActionResult> HandleUpdateProfile(ProfileModel model)

And now the "profileModel" that comes as a parameter is correctly set but without the changes!

No, the profileModel doesn't arrive evaluated to the controller

I have no errors, I created a macro with "Edit profile" snippet and the prfofileModel is not evaluated in the controller. I'm using Umbraco v11.

I've removed disabled and Username is ok. But all member's properties, key, creation date and others... have not a value.

There is a loop on the member properties which are also bound to their input tags. So the values are changeable from the front-end but not pass to the controller

for (var i = 0; i < profileModel.MemberProperties.Count; i++)
{
 @Html.LabelFor(x => profileModel.MemberProperties[i].Value, profileModel.MemberProperties[i].Name)
 <input asp-for="@profileModel.MemberProperties[i].Value" class="form-control" />
}

At the end of everything, out of the table tag but into "using":

<button type="submit" class="btn btn-primary ">Update</button>

is working on a reply...
