Hi,

I think you cannot avoid form to load on click of refresh button of the browser.
instead you can make use of "IsPostBack" property of the page.

The difference is when you click on refresh button, then value of "IsPostBack=false", but if click on button, "IsPostBack=true".

so before excecuting your code, you can check the value of "IsPostBack" property and place the code accordingly.

hope it helps.

This is due to how browsers work. The first time you POST the page, the browser sends all the data, then returns back HTML to render. If you hit refresh (F5) then the browser re-sends the last POST request thus re-sending the information again. This causes duplication of record. One need to apply Post-Redirect-Get pattern for such scenarios/pages, where after an HTTP Post, instead of returning HTML, is redirected back to a page (either the same or another).

In case, you cannot redirect or not comfortable with redirect, have a look at these articles:
