Hi guys,

I'm working on file upload, but i dont know why its not taking any files.

i have added fileupload in asp.net page with upload button,

i select one file n click upload button, on button its i get the fileone.hasfile as empty.

my code:

C#

protected void btnupload_Click(object sender, EventArgs e)
        {
            if (PhotoUpload1.HasFile)
            {
                Session["ImageBytes"] = PhotoUpload1.FileBytes;
                string str = Server.MapPath(PhotoUpload1.FileName);
                ImagePreview.ImageUrl = "~/DriverSetup/" + PhotoUpload1.FileName;
            }

        }

its not going into if loop, just return false;

plz suggest me,

update panel code:

<pre lang="xml"><asp:UpdatePanel ID="UpdatePanel1" runat="server">
                                      <ContentTemplate>
                                      <asp:Image CssClass="img img-thumbnail" Width="150px" Height="180px" ID="ImagePreview" runat="server" />
                                      <br />
                                      <asp:FileUpload ID="PhotoUpload1" runat="server" />
                                       <br />
                                       <asp:Button ID="btnupload" runat="server" Text="Upload"
                                          onclick="btnupload_Click" />
                                          <asp:UpdateProgress ID="UpdateProgress1" runat="server">

                                          </asp:UpdateProgress>
                                      </ContentTemplate>
                                      <Triggers>
                                      <asp:PostBackTrigger ControlID="btnupload" />

try this

C#

protected void UploadButton_Click(object sender, EventArgs e)
{
    if(FileUploadControl.HasFile)
    {
        try
        {
            if(FileUploadControl.PostedFile.ContentType == "image/jpeg")
            {
                if(FileUploadControl.PostedFile.ContentLength < 102400)
                {
                    string filename = Path.GetFileName(FileUploadControl.FileName);
                    FileUploadControl.SaveAs(Server.MapPath("~/") + filename);
                    StatusLabel.Text = "Upload status: File uploaded!";
                }
                else
                    StatusLabel.Text = "Upload status: The file has to be less than 100 kb!";
            }
            else
                StatusLabel.Text = "Upload status: Only JPEG files are accepted!";
        }
        catch(Exception ex)
        {
            StatusLabel.Text = "Upload status: The file could not be uploaded. The following error occured: " + ex.Message;
        }
    }
}

Its very common issue when we use FileControl with UpdatePanel. Should use Triggers.

Add this in your update panel, ASPX page

ASP.NET

<Triggers>
            <asp:PostBackTrigger ControlID="btnupload" />
        </Triggers>
    </asp:UpdatePanel>
