not able to find .FindControl while coding in rowupdating event

I have a grid with 3 columns empName, bonus, Id

I wanted to implement edit functionality on gridview.

For that i went into editTemplates and added 3 textboxes:

<EmptyDataTemplate>
                <asp:TextBox ID="txtEmpName" runat="server"></asp:TextBox>
                <asp:TextBox ID="txtBonus" runat="server"></asp:TextBox>
                <asp:TextBox ID="txtID" runat="server"></asp:TextBox>
</EmptyDataTemplate>

I am refering to THIS doccument for the code.

According to this i tried to write code like:

TextBox txtUname = (TextBox)gv.DataKeys[e.RowIndex].FindControl("txtEmpName");

But after (TextBox)gv.DataKeys[e.RowIndex]. it is not showing me FindControl

Is there any mistake in the steps i have followed for this procedure?

Please help me.

The DataKeys and DataKeyNames are used to store values that you define in the gridview. What you simply need is 

TextBox txtUname = (TextBox)gv.Rows[e.RowIndex].FindControl("txtEmpName");

In case you want to know more how DataKeys can be used try google or check out this example :

TextBox txtUname = (TextBox)gv.DataKeys[e.RowIndex].FindControl("txtEmpName");

instead use Rows as 

TextBox txtUname = (TextBox)gv.Rows[e.RowIndex].FindControl("txtEmpName");

And it should be "EditItemTemplate" instead of "EmptyDataTemplate"
