英文:
check box not display checked although it have value true on database?
问题
我在使用 .NET Core 7 开发 Blazor 应用程序时遇到了一个问题，即当尝试检索复选框布尔值 IsActive 的值时出现了问题。
在数据库中，IsActive 的值为 1，但在 Blazor 应用程序中，复选框显示为 false。
如何解决这个问题？
我的代码如下：
我的问题是，尽管数据库中存在值为 1（已选中），但复选框显示为未选中。
<div class="modal fade" id="exampleModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true">
<EditForm Model="@sn" OnValidSubmit="submit">
<div class="modal-body">
<div class="d-flex flex-row bd-highlight mb-3">
<div class="p-2 w-100 bd-highlight">
<div class="form-group row">
<div class="input-group mb-3">
<div class="input-group-text">
<input type="checkbox" aria-label="IsActive" id="IsActive" @bind-value="@sn.IsActive" />
</div>
<label class="form-check-label" for="IsActive">IsActive?</label>
</div>
</div>
</div>
</div>
</div>
</EditForm>
</div>
@code
{
private bool IsActive { get; set; }
private ServerNames sn = new ServerNames();
private void editClick()
{
if (IsActive == true)
{
sn.IsActive = true;
}
else
{
sn.IsActive = false;
}
}
}
请帮助解决这个问题。

<EditForm ... 是一个内置组件，旨在与相应的组件一起使用，例如 <InputText...。在您的情况下，<InputCheckbox @bind-Value="@sn.IsActive"。Value 是 InputCheckbox 的属性。
要绑定到 <input type="checkbox"，只需使用 @bind=
<input type="checkbox" ... @bind="@sn.IsActive" />
英文:
<EditForm ... is a built-in component designed to be used with the corresponding components for example <InputText.... In your case <InputCheckbox @bind-Value="@sn.IsActive". Value is a property of InputCheckbox
To bind to a <input type="checkbox" just use @bind=
<input type="checkbox" ... @bind="@sn.IsActive" />
