To customize a validation message component in Blazor, follow these steps:
Create a new Razor component with the desired name, such as "CustomValidationMessage".
Add a parameter to the component to accept the validation message string:
[Parameter]
public string Message { get; set; }
@if (!string.IsNullOrEmpty(Message))
{
<div class="validation-message">@Message</div>
}
.validation-message {
color: red;
font-weight: bold;
margin-top: 0.5rem;
}
<EditForm Model="@myModel" OnValidSubmit="@HandleValidSubmit">
<div class="form-group">
<label for="name">Name</label>
<InputText id="name" class="form-control" @bind-Value="myModel.Name" />
<CustomValidationMessage Message="@nameErrorMessage" />
</div>
</EditForm>
In this example, the "CustomValidationMessage" component is used to display a validation error message for the "Name" input field, with a custom CSS style and content passed as a parameter.
