Question

I have an asp.net page which loads and writes values from a record to the controls on the page.

There is a link to another page and a save button.

If the user clicks save, fine, the changes are saved and they can navigate to wherever.

If they dont click save and click the link, any changes are lost.

Is there a way to check if the save has been clicked while the user has that page loaded?

I’m thinking along the lines of an OnClick Javascript function for the link such as -below, I’m not sure though how to test for the save button being clicked – can anyone point me in the right direction?

function handleHyperLinkClick(hyperlink) 
{ 
    confirm("You have not clicked save, any changes will be lost - click cancel then save  your changes or ok to continue");
 } 

Answer 1

Add a bool variable, that is default false, set to true if the button has been clicked. Then check the value if user leaves the page.
