我如何从后面的代码中调用void函数？

Question

When calling a codebehind function from a aspx file I use this tag:

<%# FunctionName(param) %>

But when using this tag the function is always requires to return a string. How do i call a void function from the codebehinde in an aspx file?

Answer 1

<%# is used to write (sanatized) output to the response, so it expects to have something to write (ie. a return value). Try using <% %> instead.
