DropDownExtender

[XIAXIANGFENG]

DropDownExtender空间。显示出来的结果只有4个，只显示出了前4个，其他的没显示出来。
如图：
code：
<asp:TextBox ID="txtMz" runat="server"
ontextchanged="txtMz_TextChanged"></asp:TextBox>
<asp:Panel ID="Panel1" runat="server" ScrollBars="Vertical" Visible="false" Height="100px">
<asp:GridView ID="GridView1" runat="server" AutoGenerateSelectButton="false"
onrowdatabound="GridView1_RowDataBound"
onselectedindexchanged="GridView1_SelectedIndexChanged"
onselectedindexchanging="GridView1_SelectedIndexChanging">
<Columns>
<asp:BoundField DataField="mz"/>
</Columns>
</asp:GridView>
</asp:Panel>
<asp:DropDownExtender ID="DropDownExtender1" runat="server" TargetControlID="txtMz" DropDownControlID="Panel1">
</asp:DropDownExtender>
