    vs express 2012



    install ajax toolkit via manage nuGet packages for solution - and tried to reinstall it...

    the prob: 

    on dialog box - cant select multiple files... just one at the time.

    i would like to have the same behavior like in the ajax control tool kit oficial page..

    add in web.config:

        <validation validateIntegratedModeConfiguration="false"/>
          <add name="AjaxFileUploadHandler" verb="*" path="AjaxFileUploadHandler.axd" type="AjaxControlToolkit.AjaxFileUploadHandler,            AjaxControlToolkit"/>

    <form id="form1" runat="server">
            <asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
                <asp:Label runat="server" ID="myThrobber" Style="display: none;"><img align="absmiddle" alt="" src="images/uploading.gif"/></asp:Label>
                <asp:AjaxFileUpload ID="AjaxFileUpload1" runat="server"
                    ThrobberID="myThrobber" MaximumNumberOfFiles="10" AllowedFileTypes="jpg,jpeg,gif" />
    protected void AjaxFileUpload1_UploadComplete(object sender, AjaxControlToolkit.AjaxFileUploadEventArgs e)
            //string filePath = "~/upload/" + e.FileName;

    on dialog box - cant select multiple files... just one at the time.

    Did you try holding CTRL key to select multiple files? When you set MaximumNumberOfFiles to 10, you should be able to select 10 files.

    Hi 2xo1,

    Thanks for your post.

    In my mind the ajax control AjaxFileUpload will generate file input with Multiple attribute.

    <input name="AjaxFileUpload1$ctl04" type="file" id="AjaxFileUpload1_Html5InputFile" multiple="multiple" style="opacity:0;-moz-opacity:0.0;filter:alpha(opacity=0);display:none;visibility:hidden;" />

    The multiple attribute supported in html5, and html5's attributes not fits all browsers.


    You can try below javascript code for test whether your broswer support multiple (select multiple files ).

    function supportMultiple() {
    	//do I support input type=file/multiple
    	var el = document.createElement("input");
    	return ("multiple" in el);

    Hope that helps, thanks.

    Best Regards!
