    Hide browse button for UploadPersistedFile control

    Hello,
     
    I am creating a customized upload control that easily allows me to upload / remove images web forms. The control should look like this:
     
     
    However, currently, it looks like this:
     
     
    This is the code I use:
     
        <%-- Uploader --%>
        <CuteWebUI:UploadPersistedFile runat="server" ID="imageUploader" UploadType="Auto" MultipleFilesUpload="false"
            InsertButtonID="editButton" CancelButtonID="cancelButton" ProgressCtrlID="imageUploaderProgress"   
            OnFileUploaded="imageUploader_FileUploaded" OnFileChanged="imageUploader_FileChanged">
            <ValidateOption AllowedFileExtensions="jpg,jpeg,gif,png" />
        </CuteWebUI:UploadPersistedFile>
     
    Why is the browse button still visible?
     
    Thanks in advance!

    Hi
     
    Can you show all the HTML code ?
     
     
    the "editButton" must be a server control , otherwise uploader control would ignore that property if "editButton" not found at server side.
     
    So do other XxxID properites.

    Re: Hide browse button for UploadPersistedFile control

    Here you go. It's the complete xml code for the user control:

    <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="ImageUploader.ascx.cs" Inherits="CatenaLogic.Website.Controls.ImageUploader" %>

    <div class="imageUploader">
        <%-- Image --%>
        <asp:Image ID="imageUploaderImage" runat="server" CssClass="photo" />
       
        <%-- Controls --%>
        <div class="controls">
       
            <%-- Progress --%>
            <asp:Panel ID="imageUploaderProgress" runat="server" CssClass="progress" />
           
            <%-- Buttons --%>
            <asp:LinkButton ID="editButton" runat="server" CssClass="editButton" meta:resourcekey="editButtonResource" />
            <asp:LinkButton ID="cancelButton" runat="server" CssClass="cancelButton" meta:resourcekey="cancelButtonResource" />
            <asp:LinkButton ID="removeButton" runat="server" CssClass="removeButton" meta:resourcekey="removeButtonResource" />
       
        </div>
       
        <%-- Uploader --%>
        <CuteWebUI:UploadPersistedFile runat="server"  ID="imageUploader" UploadType="Auto" MultipleFilesUpload="false"
            CancelButtonID="cancelButton" InsertButtonID="editButton" ProgressCtrlID="imageUploaderProgress"   
            OnFileUploaded="imageUploader_FileUploaded" OnFileChanged="imageUploader_FileChanged">
            <ValidateOption AllowedFileExtensions="jpg,jpeg,gif,png" />
        </CuteWebUI:UploadPersistedFile>
    </div>

    Re: Hide browse button for UploadPersistedFile control

    Hi CatenaLogic,
     
    As long as you change the id of uploader(imageUploader) or image(imageUploaderImage),the issue will be solved,because the two  ID co-exist will bring script conflict.

    Re: Hide browse button for UploadPersistedFile control

    Thank you very much, this seems to work. I also had to change the progress bar name.
     
    I have another simple question: I forgot to copy ajaxuploader.lic to the bin directory. Then, the control complained about a license. Is the license checked cached or is it really checked every call (that would be a huge performance hit)?

    Re: Hide browse button for UploadPersistedFile control

    I now have this source:
     
    <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="ImageUploader.ascx.cs" Inherits="CatenaLogic.Website.Controls.ImageUploader" %>

    <div class="imageUploader">

    <%-- Image --%>

    <asp:Image ID="previewImage" runat="server" CssClass="photo" />

     

    <%-- Controls --%>

    <div class="controls">

     

    <%-- Progress --%>

    <asp:Panel ID="uploadProgress" runat="server" CssClass="progress" />

     

    <%-- Buttons --%>

    <asp:LinkButton ID="editButton" runat="server" CssClass="editButton" meta:resourcekey="editButtonResource" />

    <asp:LinkButton ID="cancelButton" runat="server" CssClass="cancelButton" meta:resourcekey="cancelButtonResource" />

    <asp:LinkButton ID="removeButton" runat="server" CssClass="removeButton" meta:resourcekey="removeButtonResource" />

     

    </div>

     

    <%-- Uploader --%>

    <CuteWebUI:UploadPersistedFile runat="server" ID="imageUploader" UploadType="Auto" MultipleFilesUpload="false"

    CancelButtonID="cancelButton" InsertButtonID="editButton" ProgressCtrlID="uploadProgress" ShowProgressInfo="false"

     

    OnFileUploaded="imageUploader_FileUploaded" OnFileChanged="imageUploader_FileChanged">

    <ValidateOption AllowedFileExtensions="jpg,jpeg,gif,png" />

    </CuteWebUI:UploadPersistedFile>

    </div>

    Initially, the control looks fine:
     
    However, when I select a file to upload, I get this error:
     
     
     
     
    Any ideas what can be wrong? As you can see, the progress bar does not show in the progressbar at the top.
     
    Also, is it possible to hide the browse button during the uploading process? I want the upload (edit) button to be replaced by the cancel upload button during the upload process.
     
     Thanks in advance!

    Re: Hide browse button for UploadPersistedFile control

     
     
    imageUploader.TempDirectory = _uploadFolder;
     
     
    Please do not use the TempDirectory property any mode.
     
    While the uploader have been upgrated to v2.0 , this property is not compatible with the Flash upload mode.
     
    We haven't prepaired the document on this issue , sorry.
     
    If you want to change the default , you can set it at web.config appSettings :
     
    <add key="CuteWebUI.AjaxUploader.TempDirectory" value="~/TempDirectory" />
     
    you can specify a physical path too, for example "d:\temp" or "\\server2\shared folder"

    Re: Hide browse button for UploadPersistedFile control

    Thank you for your reply.
     
    In that case, I have a new feature request: make it available in the control itself again. The reason for this is that I want to be able to simply add the user control to a page and I don't want to modify the web.config (which doesn't make sense in case of a user control).
