->It is used to get value of primary key column in Grid view .
->Using this It is possible to delete a row in edit mode in gridview
ex----<asp:Gridview ID="gdv" runat= "server" DataKeyNames="primarykey column name"></asp:Gridview>

in code behind we get value

int Id = Convert.ToInt32(gdv.DataKeys[e.RowIndex].Values[0]);

using this Id we can delete any row in gridview edit mode also
