If you want to Get the Data Key value on the Click of the ImageButton/LinkButton, you can set the DataKey value to the CommandArgument property of your control and then in the Click handler you can get the value from the CommandArgument property.

<asp:ImageButton ID="ibtn" runat="server" CommandArgument='<%# Eval("DataKeyName")%>'
 ImageUrl="~/Images/edit.png"></asp:ImageButton>

Same case for linkbutton as well.

Inside the button click event, you can do the following to get the DataKey and the Label (assuming it's in the same control collection as the button):

var button = sender as Button;

if (button == null) return;

var dataListItem = button.NamingContainer as DataListItem;

if (dataListItem == null) return;

var currentKey = DataList1.DataKeys[dataListItem.ItemIndex];

var myLabel = button.Parent.Controls.Cast<Control>().FirstOrDefault(x => x.ID == "testLabel") as Label;

if (myLabel == null) return;

var myLabelText = myLabel.Text;
