आइटम को अपडेट करने या अद्यतन की गई इवेंट दस्तावेज़ लायब्रेरी में दो बार होता है

Item Updating or Item Updated Event in SharePoint 2007 occurs twice, if require checkout option is enabled for document library.

I found the following workaround from Microsoft Support for this issue.

Check the value of vti_sourcecontrolcheckedoutby
में BeforeProperties और AfterProperties, if the both values are null then the event is triggered by check in else the event is triggered by other actions.

if (properties.AfterProperties[“vti_sourcecontrolcheckedoutby”] == null && properties.BeforeProperties[“vti_sourcecontrolcheckedoutby”] != null)

{

//This is when the update event is triggered by check-in.

}

else

{

//This is triggered by events other than check-in action.

}
