Introduction: In previous articles i explained How to read DataKeyNames on GridView's RowDeleting event in asp.net and How to read DataKeyNames from GridView on RowEditing event of gridview and How to read DataKeyName from GridView onSelectedindexChanging event of GridView 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 RowUpdating Event in asp.net.Suppose you have a GridView grdEmp having DataKeyNames DataKeynames EMP_ID  and you want to read EMP_ID from DataKeyNames on Gridview’s RowUpdating Event then here is  the code:

Note: We are assuming EMP_ID is the primary key of the Employee table

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

</GridView>

protected void grdEmp_RowUpdating(object sender, GridViewUpdateEventArgs e)

    {     

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

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

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

    }

VB.Net Code to read DataKeyNames on GridView's RowUpdating Event in asp.net
Protected Sub grdEmp_RowUpdating(sender As Object, e As GridViewUpdateEventArgs)

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

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

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

End Sub
