                                        </td>
                                    </tr>
                                </ItemTemplate>
                            </asp:ListView>
                        </div>
                    </div>

i have 3 coloumns that contains different link button. Each one should automaticaly download the related file based on DataKeyNames ="Id_lamaran", but i have no idea how to start to get related datakey by each button?

the main goal, user can perform specific download for specific file on specific record based on link button in each row

does any one have a clue ?

but i have no idea how to start to get related datakey by each button?

First subscribe to Click event of button 

<asp:LinkButton ID="LinkButton1" runat="server" OnClick="LinkButton1_Click">Download Certificate</asp:LinkButton>

Now you can access data keys like below

protected void LinkButton1_Click(object sender, EventArgs e)
		{
			var button = sender as LinkButton;

			// Get the selected listview item
			ListViewItem item = button.NamingContainer as ListViewItem;
			// Get the datakey from listview
			// Change the listview id and datakey name here
			string DataKeyvalue = LvPelamarBaru.DataKeys[item.DataItemIndex].Values["Id_lamaran"].ToString();
		}
