SPList lstAstatus = currentWeb.Lists["AlgorithmStatus"];
SPListItem ListItem = lstAstatus.Items.Add();
ListItem["LoginName"] = currentWeb.CurrentUser.Name;
ListItem["Task"] = "AlgorithmCalculation";
ListItem["Status"] = "C";
this.EventFiringEnabled = false;
ListItem.Update();
this.EventFiringEnabled = true;

}
- 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 “<Receivers>” 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>
