这是我到现在为止所得到的。我的问题是什么?
1)当我使用键盘导航键将鼠标悬停在弹出列表上时,它会在文本框中显示项目,但是当我使用鼠标时,它不会显示在文本框中。(?) 。
2)当我选择列表项时,它会在文本框中被选中,但不会触发文本框textchange事件。(?)。
我的aspx
this is what i got till now. What is my problem is
1) when i hover over the popup lists using keyboard navigation key it displays items in text box, but when I use mouse it doesn''t display in textbox.(?).
2) when i select the list item it gets selected in text box but does not fire text box textchange event.(?).
my aspx
<asp:UpdatePanel ID="up" runat="server"><contenttemplate>
<asp:HiddenField ID="hfCustomerId" runat="server" />

ontextchanged="txtSearch_TextChanged">
<asp:Button ID="bttnSearch" runat="server" CssClass="submit" Height="23px" Text="Search" onclick="bttnSearch_Click" />
