Why the gridView_RowUpdating events get hit again when I refresh the page after it completed the update?

Hi, I'm using VS2012.

After the end of the gridView_RowUpdating, I set the EditIndex to -1.  Doesn't this signal that updating event is completed?  The gridview returns to the original state and the UPdate and Cancel button goes away.  I then click Refresh (in the browser next to the url) icon to refresh the page, then it hit my break point in VS that is in gridView_RowUpdating event.  

Why is it hitting that updating event code again?  How to fix this?  Thank you.

let's have a Boolean variable (bolBypass) to be set to true or false (in postback == true or postback != true whichever you are using).

Then use:
if bolBypass== true 
{
// run your update routine
bolBypass = false  // this resetting will prevent update running for 2nd time
}

Open in new window


You need to figure out the location and setting of  bolBypass = ? in your  postback == true or postback != true.

Tricky hard to say without looking at the whole page code,
if your code is firing two times only, then your issue may get solved as follows:
1) Check that your event handler is not being set more than once in your site.
For example you may be defining the handler on your grid view mark-up and C#code.
2) Check that your code is not updating the database after the data is bound to the grid view.
