Is JavaScript necessary for the ASP.NET OnClick attribute?

Take this scenario, for instance: 

<asp:Button id="Button1"
               Text="Click here for greeting..."
               OnClick="GreetingBtn_Click" 
               runat="server"/>

Therefore, I pose these inquiries:

  1. Is the OnClick attribute related to a javascript event on the client side? If so, does it imply that asp.net will inject javascript code into the page before sending it back to the browser?

  2. Considering JavaScript's case sensitivity, should "OnClick" actually be written as "onclick"?

Answer №1

If you take a look at this link, you'll notice that this event will trigger server-side execution. However, ASP.NET also generates client-side code like the following:

onclick="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(...

Therefore, clicking on the button will initiate a postback to the server.
