ASP.NET MVC AjaxOptions, OnBegin / Onsuccess / OnFailure
Posted by Kristof in .NET, ASP.NET, MVC, ProgrammingIf you have a Ajax.Actionlink and you want to specify a OnBegin with a parameter you need to use the following syntax:
<%=Ajax.ActionLink("text", "Action", "Controller", new { param = someVar }, new AjaxOptions() { OnBegin = string.Format("new Function(‘DoSomeThing({0})’)", index), HttpMethod = "POST" })%>
Where DoSomeThing is just a function that takes a string as parameter.
Update: added quotes around the real (inner) function, otherwise it’s executed instead of passed on at the creation of the object.

Why does the string.Format not have a {0} in it? are the tick marks ` intentional or are they mean to be single quotes?
Those backticks are single quotes, I don’t know why my blog makes them backticks. And indeed, I forgot the {0}, thanks for that. It’s because I refactored my function to something more generic. I will fix it soon
