I made an asp.net website, but the checkbox is always false. Why is this so?
Model:
public string Username { get; set; }
public string Password { get; set; }
public bool Remember { get; set; }
CSHTML:
<div class="form-group">
@Html.Label("Remember me?")
@Html.CheckBoxFor(m => m.Remember)
</div>
The Remember property is always false, if the checkbox is checked then Rememberis still false.
I got the same issue, I fixed it by writing html checkbox tag, giving it the name same as property name, and value = true, if the checkbox is not checked no need to worry as it won't be submitted anyway, in your case this will be it
<input type="checkbox" name="Remember" value="true" />
CheckBoxFor just plain doesn't work. Who knows if it ever did.With Razor, I had the same problem. What worked for me was taking off the value="xxx" tag. Then it functioned normally.
Does not work:
<input class="form-check-input" value="true" asp-for="Answer.aIsCorrect" />
Works:
<input class="form-check-input" asp-for="Answer.aIsCorrect" />
The first parameter is not checkbox value but rather view model binding for the checkbox hence:
@Html.CheckBoxFor(m => m.SomeBooleanProperty, new { @checked = "checked" }); The first parameter must identify a boolean property within your model (it's an Expression not an anonymous method returning a value) and second property defines any additional HTML element attributes. I'm not 100% sure that the above attribute will initially check your checkbox, but you can try. But beware. Even though it may work you may have issues later on, when loading a valid model data and that particular property is set to false.
