Introduction: In previous articles i explained How to read DataKeyNames from GridView on RowEditing event of gridview in asp.net and How to read DataKeyName from GridView on SelectedindexChanging event of GridView in asp.net and How to read DataKeyNames on GridView's RowUpdating Event in asp.net and How to set and read multiple DataKeyNames in Gridview in asp.net.

Now i will explain How to read DataKeyNames on GridView's RowDeleting event in asp.net.
Suppose you have a GridView grdEmp having DataKeyNames EMP_ID and you want to read EMP_ID from DataKeyNames on Gridview’s RowDeleting event then here is the code:

Place a GridView control on the design page(.aspx)

<asp:GridView ID="grdEmp" runat="server" DataKeyNames="EMP_ID">

</GridView>

C#.Net Code  to read DataKeyNames on GridView's RowDeleting event

protected void grdEmp_ RowDeleting (object sender, GridViewDeleteEventArgs e)

    {     //First way

     int empId = Convert.ToInt32(grdEmp.DataKeys[e.RowIndex].Value); 
      //Second way

     int empId = Convert.ToInt32(grdEmp.DataKeys[e.RowIndex].Value.ToString());
      //Third way

      int empId = Convert.ToInt32(grdEmp.DataKeys[e.RowIndex].Values["EMP_ID"].ToString());

    }

VB.NET Code to read DataKeyNames on GridView's RowDeleting event

Protected Sub grdEmp_RowDeleting(sender As Object, e As GridViewDeleteEventArgs)

    'First way                  
     Dim empId As Integer = Convert.ToInt32(grdEmp.DataKeys(e.RowIndex).Value)

     'Second way                   
     Dim empId As Integer = Convert.ToInt32(grdEmp.DataKeys(e.RowIndex).Value.ToString())           

'Third way                   
   Dim empId As Integer = Convert.ToInt32(grdEmp.DataKeys(e.RowIndex).Values("EMP_ID").ToString()) 

End Sub
