Asp. NET to execute the control (such as ImageButton, LinkButton, etc.) command does not refresh the page _ Practical tips

Functional Requirements : Use the ImageButton control in the framework to close the application query "confirm Exit" and invoke JavaScript in ImageButton's OnClick event (C #) to shut down ie.

Issue : Pop-up dialog box, you will lose the contents of the child interface, even if you do not exit the system, can not return to the original state.

solution : Do not use the ImageButton OnClick event (C #) directly, but through the way of ImageButton's Attributes.Add ("OnClick", "javascript: ..."), will be able to solve the problem.
