我正在使用 updatepanel 来避免回发,并且代码在 IE8 和 firefox 中运行良好,但在 IE9 中却不行。我也尝试从 codeplex 安装最新的 ajax 工具包,但它也没有帮助我。请帮助我。我的代码如下/....
<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>
