我已经安装了AjaxControlToolKit，添加了对它的引用，将这些控件添加到工具箱中。 ajaxToolkit:AsyncFileUpload是可识别的。但是，我正在为ajaxToolkit:ToolkitScriptManager而"The type or namespace name 'ToolkitScriptManager' does not exist in the namespace 'AjaxControlToolkit' (are you missing an assembly reference?)".

如何解决？

添加 ScriptManager AS 

    <div>
        <asp:ScriptManager ID="ScriptManager1" runat="server">
        </asp:ScriptManager>
        <div>
            <ajaxtoolkit:AsyncFileUpload runat="server" ID="fileUpload1" OnClientUploadComplete="uploadComplete"
                OnClientUploadError="uploadError" CompleteBackColor="White" Width="350px" UploaderStyle="Modern"
                UploadingBackColor="#CCFFFF" ThrobberID="imgLoad" OnUploadedComplete="fileUploadComplete">
            </ajaxtoolkit:AsyncFileUpload>
            <br />
            <asp:Image ID="imgLoad" runat="server" ImageUrl="loading.gif" />
            <br />
            <asp:Label ID="lblMsg" runat="server" Text=""></asp:Label>
        </div>
    </div>
