Hi, @João Coelho , you can override the OnInitialized method. It will execute when page load.

@code {  
    private int state = 0;  
    private string readBg { get; set; }  
    private string greenBg { get; set; }  
    private string blueBg { get; set; }  
  
    protected override void OnInitialized() // = On PageLoad  
    {  
        readBg = "red";  
        greenBg = "green";  
        blueBg = "blue";  
    }  
}  

Hi, @João Coelho ,

You could try as below.

@code {  
    private int state = 0;  
    private string Background { get; set; } = "red";  
  
    private void ChangeValues()  
    {  
        state++;  
        if (state % 3 == 0)  
            Background = "red";  
        if (state %3 == 1)  
            Background = "green";  
        if (state % 3 == 2)  
            Background = "yellow";  
    }  
}
