解决方案
讨论：这是至关重要的，它使用IE9的是？如果不是，那么你可能只是迫使它呈现为IE8具有以下code在页面或母版页的head部分插入。
可能的解决方案：
＆LT; META HTTP-当量=X-UA-Compatible的内容=IE = IE8/＆GT;
更新的响应
已确定问题：我看看你的code和你的最后一个TR元素内没有更新面板。我现在想象，code，最初的工作在IE8，因为你可能有另一个更新面板，整个表盖。
I am using updatepanel to avoid the postback and the code is working fine in IE8 and firefox but not in IE9. I also tried installing latest ajax toolkit from codeplex but it did not help me either.Please help me with this. My code is something like below/....
<table width="800px">
<tr>
<asp:UpdatePanel runat="server" ID="upCountry">
<ContentTemplate>
<td class="TextLabelForHeader" width="300px">
Country:
<asp:RequiredFieldValidator ID="RequiredFieldValidator4" runat="server" ControlToValidate="ddlCountry"
ErrorMessage="*" InitialValue="Select.." ValidationGroup="VGHeader"></asp:RequiredFieldValidator>
</td>
<td align="left">
<asp:DropDownList ID="ddlCountry" runat="server" OnSelectedIndexChanged="ddlCountry_SelectedIndexChanged"
AutoPostBack="true" OnDataBound="ddlCountry_DataBound" onchange="SelectCurrency(this);"
ValidationGroup="VGHeader">
</asp:DropDownList>
</td>
<td align="left">
</td>
</ContentTemplate>
</asp:UpdatePanel>
</tr>
<tr>
<asp:UpdatePanel runat="server" ID="upCurrency">
<ContentTemplate>
<td class="TextLabelForHeader" width="300px">
Currency:
</td>
<td align="left">
<asp:DropDownList ID="ddlCurrency" runat="server" ValidationGroup="VGHeader">
</asp:DropDownList>
</td>
<td align="left">
</td>
</ContentTemplate>
</asp:UpdatePanel>
</tr>
<tr>
<td class="TextLabelForHeader" width="300px">
Client:
<%--<asp:RequiredFieldValidator ID="RequiredFieldValidator5" runat="server"
ControlToValidate="ddlClient" ErrorMessage="*" InitialValue="Select.."
ValidationGroup="VGHeader"></asp:RequiredFieldValidator>--%>
<asp:RequiredFieldValidator ID="RequiredFieldValidator5" runat="server" ControlToValidate="txtClient"
ErrorMessage="*" ValidationGroup="VGHeader"></asp:RequiredFieldValidator>
</td>
<td align="left">
<%-- <asp:DropDownList ID="ddlClient" runat="server" Height="16px" Width="143px" Enabled="false"
OnDataBound="ddlClient_DataBound" onchange="DisplayTextbox(this);" ValidationGroup="VGHeader">
</asp:DropDownList>--%>
<asp:TextBox ID="txtClient" runat="server" Width="143px" ReadOnly="true" ValidationGroup="VGHeader"></asp:TextBox>
<%--<div id="form_ProductContainer" style="display: none;">
<asp:TextBox ID="txtNewClientName" runat="server"></asp:TextBox>
</div>--%>
</td>
<td class="TextLabelForHeader" style="text-align: left;">
<asp:Button ID="btnContinue" runat="server" OnClick="btnContinue_Click" Text="Continue"
ValidationGroup="VGHeader" />
</td>
</tr>
</table>
解决方案
Discussion: Is it vital that it uses IE9 as is? If it isn't then you could just force it to render as IE8 with the following code inserted in the head section of the page or master page.
Possible Solution:
<meta http-equiv="X-UA-Compatible" content="IE=IE8" />
Updated Response
Identified Issue: I had a look at your code and you have no update Panel inside the last TR element. I imagine now that the code originally worked in IE8 because you probably had another update panel that covered the entire table.
