- In Solution Explorer open “Elements.xml”
To use an event receiver for one specific list:
- Replace the attribute “ListTemplateId” with “ListUrl” and add your url as value:
------------------------------------------------------------------------------------

<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
 
 <Receivers  ListTemplateID="100">
      <Receiver>
        <Name>LogHistoryItemDeleting</Name>
        <Type>ItemDeleting</Type>
        <Assembly>$SharePoint.Project.AssemblyFullName$</Assembly>
        <Class>Axalta.Global.DpciformsLogHistory.LogHistory.LogHistory</Class>
        <SequenceNumber>10000</SequenceNumber>
      </Receiver>
  </Receivers>

</Elements>
--------------------------------------------------------------------------------------
-> Replace With:
<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">  
 <Receivers  ListUrl="Lists/NotesCda">
      <Receiver>
        <Name>LogHistoryItemDeleting</Name>
        <Type>ItemDeleting</Type>
        <Assembly>$SharePoint.Project.AssemblyFullName$</Assembly>
        <Class>Axalta.Global.DpciformsLogHistory.LogHistory.LogHistory</Class>
        <SequenceNumber>10000</SequenceNumber>
      </Receiver>
  </Receivers>
</Elements>
… Tip:
To use an event receiver for two or more lists:
You have to add one more “&ltReceivers&gt” node
Sample:
<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">  
 <Receivers  ListUrl="Lists/List1">
      <Receiver>
        <Name>LogHistoryItemDeleting</Name>
        <Type>ItemDeleting</Type>
        <Assembly>$SharePoint.Project.AssemblyFullName$</Assembly>
        <Class>Axalta.Global.DpciformsLogHistory.LogHistory.LogHistory</Class>
        <SequenceNumber>10000</SequenceNumber>
      </Receiver>
  </Receivers>

 <Receivers  ListUrl="Lists/List2">
      <Receiver>
        <Name>LogHistoryItemDeleting</Name>
        <Type>ItemDeleting</Type>
        <Assembly>$SharePoint.Project.AssemblyFullName$</Assembly>
        <Class>Axalta.Global.DpciformsLogHistory.LogHistory.LogHistory</Class>
        <SequenceNumber>10000</SequenceNumber>
      </Receiver>
  </Receivers>
</Elements>
