you need to set AutoPostBack="true"

<asp:DropDownList ID="drpDist" runat="server" AutoPostBack="true">

when you set that property as true, a postback to the server automatically occurs whenever the user changes the selection of the list

You need to set the AutoPostBack="True" property. This will make the page to postback automatically hence firing your event.
