ASP.NET Razor Page - Set Other Class Variable From Form Input

Question

I have a simple form as such:

'''
<form method="post">
    <label type="text" asp-for="@OtherClass.Key"/>
    <button type="submit" asp-page="Page">Submit</button>
</form>
'''

I am trying to get a string input and when the submit button is clicked, set a static string variable of another class to the input value.

'''
public class OtherClass {
    public static string Key { get; set; }
}
'''

I'm new to ASP.NET so I guess I'm generally asking how to set a static variable of a different class from a form?

Answer 1

You can not directly bind the input value to a static property.

<form method="post">
    <input type="text" asp-for="Key" />
    <button type="submit" asp-page="Page">Submit</button>
</form>

Assign the input value to it in the post method.

[BindProperty]
public string Key { get; set; }

public void OnGet()
{
    Key = OtherClass.Key;
}

public void OnPost()
{
    OtherClass.Key = Key;
}
