Hi,

Search for GET after POST - http://en.wikipedia.org/wiki/Post/Redirect/Get - basically, redirect to the current page after you're finished processing your event.

Something like:

C#

Response.Redirect(Request.RawUrl)

Here is an article for Detecting Page Refresh[^].

And also see:
http://stackoverflow.com/questions/553227/refresh-the-page-after-a-postback-action-in-asp-net[^]
http://stackoverflow.com/questions/7527243/save-button-click-event-getting-fired-up-on-refreshing-the-page-once-done-with-b[^]

Here is a similar discussion:
Avoid button click event on page refresh[^]
I'll recommend you to see this.

Store your data in session and persist that again in your page. That is the only solution which I found .

CH Guravaiah 23-Jul-12 6:31am

_Amy 23-Jul-12 6:35am

_Amy 23-Jul-12 7:17am

Not only you. Everybody is facing this problem. And as I found the solution for that, I thought it may help you. The previous event record is always used to store there in the browser cache. Try deleting that.
