A pretty common task needed within a gridview or repeated is to confirm an action when the user clicks on this. (typically a delete)

The solution to this is pretty simple.  Simple add the following code to the control tag.
OnClientClick='return confirm("Are you want to delete this ?");'

An example template field in a Gridview would look something like this
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton CommandArgument='<%# Eval("ItemId") %>' CommandName="DeleteItem" Text="Delete" runat="server" OnClientClick='return confirm("Are you want to delete this Item?");' />
</ItemTemplate>
</asp:TemplateField>
