# WebMethodAttribute

Namespace: **Wisej.Core**

Assembly: **Wisej.Framework** (4.0.0.0)

Indicates that the method can be called from the browser using JavaScript.

{% tabs %}
{% tab title="C#" %}

```csharp
public class WebMethodAttribute : Attribute
```

{% endtab %}

{% tab title="VB.NET" %}

```visual-basic
Public Class WebMethodAttribute
    Inherits Attribute
```

{% endtab %}
{% endtabs %}

You can add this attribute to static methods in your Wisej application Program class and to instance methods in top level containers: Page, Form, and Desktop.\
If you want to register web methods on child controls, you can, but Wisej only searches top level containers automatically. To register web methods on a child control, extend the control class, override [OnWebRender](/api/wisej.web/general/control.md#onwebrender) and call [RegisterWebMethods](/api/wisej.web/general/control.md#registerwebmethods).

```csharp

public class MyButton : Button
{
  protected override void OnWebRender(dynamic config)
  {
    base.OnWebRender((object)config);
    RegisterWebMethods(config);
  }
}

```

Default parameters are not supported in Web Methods. This is supported:

```csharp

[WebMethod]
public void myWebMethod(string s)

```

But this is not supported:

```csharp

[WebMethod]
public void myWebMethod(string s = "default value")

```
