解决方案

通过这个： onClick =ImageButton1_Click ，你试着绑定一个方法作为ImageButton click事件的事件处理程序...该方法不存在...

在你的代码隐藏应该是一个方法 - 该页面类的一部分 - 名为ImageButton1_Click。 ..

Compilation Error

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS1061: 'ASP.main_master' does not contain a definition for 'ImageButton1_Click' and no extension method 'ImageButton1_Click' accepting a first argument of type 'ASP.main_master' could be found (are you missing a using directive or an assembly reference?)

解决方案

By this: onClick="ImageButton1_Click", you try to bind a method as the event handler of the ImageButton click event...That method does not exist...
In you code-behind should be a method - part of that page-class - named ImageButton1_Click...
