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

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

One reason is to avoid name collision or avoid the problem of Identity which can lead to collision in method overriding. However, please note that absolute multiple inheritance is not possible in C# but C# partially supports multiple inheritance via Interfaces.

No.The Repeater control is used to display a repeated list of items that are bound to the control. The Repeater control may be bound to a database table, an XML file, or another list of items.

Yes, repeater also have that capability to edit,delete and update the record.

We have to explicitly write the code for that, as we write for the binding of db.
