  - by Daniel

I want to make it a different color to stand out but I do not see any options that reference this option specifically.

• Using the Callback Method on a View in ASP.NET MVC

  - by Tony

  I have a master page with that code: public string CallbackMethod; protected void Page_Load(object sender, EventArgs e) { CallbackMethod = Page.ClientScript.GetCallbackEventReference(this, "message", "Dodanie", "context", true); } /other code here/ then, in the View (which is based on that master page) I need to invoke the CallbackMethod string, but the problem is, the framework firstly renders the View, and then invokes the Page_Load method. As the obvious result, the error appears: the name 'CallbackMethod' does not exist in the current context. How do I fix this?
