Itemupdating event fires twice

Our issue is that now that we're using the Facebook Pixel Implementation option, there's no way for us to add first_time_accessed tags, so the conversion pixel fires when someone purchases and every time that they check their order status.

Does anyone know how to use the new Facebook Pixel Implementation field AND add a first_time_accessed tag, so we can use the automated integration without having the conversion pixel fire on the check order status page too?

Users can change data like the number of moons or the distance to the earth, but they are not able to change the name of the planet.

To prevent users from changing the name of the planet, you can develop a Item Updating event receiver.

If the name isn’t changed, the changes are saved to the Share Point list.

Before you can deploy the event receiver you have to change the file to bind the Update Adding event receiver to all custom lists.

I added Method is Item Deleting(Synchronous Event) So after parent list item is deleted this list event handler calls and checkreferencefuntion check whether child list has items with Parent ID which we are needed to be deleted.

The changed values can be retrieved from the After Properties of the incoming properties argument.

You could think that the current values are stored in the Before Properties of the item but that’s not true: the Before Properties are unreliable at this point. When the name of the planet is changed, the update is canceled and an error message is returned to the user.

This event occurs before the data is saved to the Share Point list.

To check if the name of the planet is changed, you can compare the Title column before the changes with the Title of the changed item.
