用AutoCompleteExtender实现的自动完成列表和输入框有间隔

Question

如图所示

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
 <asp:AutoCompleteExtender ID="TextBox1_AutoCompleteExtender" runat="server" 
     CompletionInterval="200" TargetControlID="TextBox1" MinimumPrefixLength="1" 
     ServiceMethod="GetList" ServicePath="WebService2.asmx" CompletionSetCount="10" 
     FirstRowSelected="True" UseContextKey="True">
 </asp:AutoCompleteExtender>

问题到底出在哪里？

Answer 1

下拉弹出层是ul，ul默认有margin/padding的，所有空白，css去掉ul的空白就行

ul,li{margin:0px;padding:0px}
