I have a viewModel containing a list and another class like so :

public class MyViewModel
{
    public List<Guids> Ids{ get; set; }

    public History HistoryRecord{ get; set; }
}

public class History
{
    public string UserName{ get; set; }
    public string Email{ get; set; }

}

and a controller action that I need to send the above data to:

public async Task<IActionResult> myAction([Bind("Ids","UserName","Email")] MyViewModel viewModel)
{
... 
    
}

i'm getting the values for userName and Email via inputs

                        <input type="text"  name="name" id="nameTextbox" placeholder="name" required />
                        <input type="text"  name="email" id="emailTextbox" placeholder="email" required />

how can I send this from a razor page?

i've tried using url.Action but this doesnt seem to work and not sure how to put multiple values in

<button type="submit"  id="confirm" onclick="location.href='@Url.Action("myAction","myController", values: new {Ids= @Model.Ids.ToList(), Name = ? , Emil = ? })'">confrim</button>

CodePudding user response：

For binding values from Razor View to action you can use the asp-for tag helper. In your example:

<input asp-for="UserName" type="text"  name="name" id="nameTextbox" placeholder="name" required />

<input asp-for="Email" type="text"  name="email" id="emailTextbox" placeholder="email" required />

Your button code replace with:

<input type="submit" value="confrim" />

Don't forget to put this code into form tag and set [HttpPost] attribute for action

Final Razor View be like:

@model MyViewModel
<form asp-action="myAction" method="post">
    <input asp-for="@Model.Ids[i]"  required />
    <input asp-for="@Model.UserName" type="text"  name="name" id="nameTextbox" placeholder="name" required />
    <input asp-for="@Model.Email" type="text"  name="email" id="emailTextbox" placeholder="email" required />
    
    <input type="submit" value="confrim" />
</form>

You can try to add hidden inputs to the form,It looks like you want to use List<Guid> Ids,here is a demo:

Model:

public class MyViewModel
{
    public List<Guid> Ids{ get; set; }

    public History HistoryRecord{ get; set; }
}

add following data to the form:

@for(var i=0;i<Model.Ids.Count;i  )
{
    <input asp-for="@Model.Ids[i]" hidden />
}
