    [CLOSED] FileUploadField doesn't work as should

    Hi,

    what I tryed to do today was upload file to my server path. fuFileUpload is a
    <ext:FileUploadField runat="server" ID="fuFileUpload"/>
    I did this in my saving logic:
                    byte[] buffer = new byte[fuFileUpload.PostedFile.ContentLength;];
                    fuFileUpload.PostedFile.InputStream.Read(buffer, 0, simpleFile.Data.FileSizeBytes);
                    //after Read operation array buffer is like a new object got every time only 0 values of all positions
    after 3hours of trying this things worked i simply changed to
    <asp:FileUpload runat="server" ID="fuFileUpload"/>
    and its worked with asp.net control like a dream.

    It's seems to be a bug. Please let me know if it's work with above example and what should I changed to make this work with ext.net.FileUploadField.

    Thanks,
    ViDom

    but why this read method doesn't work and why there is no examples on your page example which will show this functionality?

    Without this examples of such a funcionality it's really hard to know why things like this one doesn't work:(

    Thanks

    I think it should work. Please provide more details. Is the FileUploadField within the <form>?
    <form runat="server">

    Well, we have such example.
    http://examples1.ext.net/#/Form/FileUploadField/Basic/

    A file is uploaded in the "Form Example" at the bottom.

    Yeah Danii FileUploadField is in
    <form runat="server">
    also got
    <ext:ResourceManager runat="server"/>

    This example which you provide got no code for saving files with it. Have only some code of uploading which i assumed do nothing. I suggest to make more detail examples there. Display isn't such important than functionality i gues ;)

    Well, the server functionality is the same as it is with <asp:FileUpload> :)
  7. #7
    In my case if it's got same functionality than <asp:FileUpload> control it should work but it isn't :P

    Your solution works for me so I'm greatfull for this :)

    Thread can be closed :)

    If you Danii will don't have anything to do pls check if this issue is only from my fault or it's a bug :)

    Thanks, but, unfortunately, I can't launch that control getting the error:
    Compiler Error Message: CS0103: The name 'btnSave' does not exist in the current context
    
    btnSave.Click += new EventHandler(btnSave_Click);
