    No items required

    Reply Quote
    Hi,
     
    I have an uploader on a page with other data.
    Uploading items is optional. But if no items are selected my page won't postback (and the rest of the data cannot be saved).
    Where do I set that uploading of images is optional in the ajaxuploader?
     
    this is my code:
     
    1. <script type="text/javascript">  
    2.   
    3.             function submitbutton_click() {  
    4.                 var submitbutton = document.getElementById('<%=btnSave.ClientID %>');  
    5.                 var uploadimg = document.getElementById('<%=uplImages.ClientID %>');  
    6.                 var uploadobj = document.getElementById('<%=uplAttach.ClientID %>');  
    7.                 if (!window.filesuploaded) {  
    8.                     if (uploadobj.getqueuecount() > 0) {  
    9.                         uploadobj.startupload();  
    10.                     }  
    11.                     if (uploadimg.getqueuecount() > 0) {  
    12.                         uploadimg.startupload();  
    13.                     }  
    14.                     return false;  
    15.                 }  
    16.                 window.filesuploaded = false;  
    17.                 return true;  
    18.             }  
    19.   
    20.             function CuteWebUI_AjaxUploader_OnPostback() {  
    21.                 window.filesuploaded = true;  
    22.                 var submitbutton = document.getElementById('<%=btnSave.ClientID %>');  
    23.                 submitbutton.click();  
    24.                 return false;  
    25.             }  
    26.         </script>  
    Any help would be appreciated
     
    thx

    Hi dbots,
     
    Please try the example below, it will submit the forum whatever the uploader control has items or not. The upload files will be the optional.
     
    <%@ Page Language="C#" %>
    <%@ Register TagPrefix="CuteWebUI" Namespace="CuteWebUI" Assembly="CuteWebUI.AjaxUploader" %>
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <script runat="server">   
     
        protected void SubmitButton_Click(object sender, EventArgs e)
        {
            label1.Text = "submit button clicked!";
        }
    </script>
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head id="Head1" runat="server">
        <title>Start uploading manually</title>
    </head>
    <body>
        <form id="form1" runat="server">

            <br />
            <br />
            <asp:Button runat="server" ID="SubmitButton" OnClientClick="return submitbutton_click()"
                Text="Submit" OnClick="SubmitButton_Click" /><br />
            <script type="text/javascript">
       function submitbutton_click() {
           var submitbutton = document.getElementById('<%=SubmitButton.ClientID %>');
           var uploadobj = document.getElementById('<%=Uploader1.ClientID %>');
           if (uploadobj.getqueuecount() == 0) {
               submitbutton.click();
           } else {
               if (!window.filesuploaded) {
                   if (uploadobj.getqueuecount() > 0) {
                       uploadobj.startupload();
                   }
                   return false;
               }
           }
           window.filesuploaded = false;
           return true;
       }
       function CuteWebUI_AjaxUploader_OnPostback() {
           window.filesuploaded = true;
           var submitbutton = document.getElementById('<%=SubmitButton.ClientID %>');
           submitbutton.click();
           return false;
       }
            </script>
        </form>
    </body>
    </html>
