I need to add a condition to a DropDownList where a method can be executed by button click only if the user has selected a value different than the listItem (default value).
<asp:DropDownList ID="DropDownList1" runat="server" AppendDataBoundItems="True"
DataSourceID="SqlDataSource5" DataTextField="proj_name" DataValueField="proj_name">
<asp:ListItem Text="Select a project to clone" Value="" />
</asp:DropDownList>
How can I structure an if condition to validate that the selected value is not the ListItem (default value)?

Then edit your button markup to use ValidationGroup
<asp:Button Id="button1" ValidationGroup="V1" .../>
In your codebehind button click code add this
