Dear Friends,

I have added a file upload option in my form. But when I check Fileupload.HasFile it give false even when I select the file.
Code Below:

XML

<asp:FileUpload
                                        ID="Resume_File"
                                        runat="server"
                                        BackColor="DodgerBlue"
                                        ForeColor="AliceBlue" />
                                        <asp:Button runat="server" id="Up_Resume_File" text="Upload"
                                            onclick="Up_Resume_File_Click"/><br /><br />
                                        <asp:Label runat="server" id="StatusLabel" text="Upload status: " />

C#

protected void Up_Resume_File_Click(object sender, EventArgs e)
    {
        if (Resume_File.HasFile)
        {
            StatusLabel.Text = "Yes";
        }
        else
        {
            StatusLabel.Text = "No";
        }
    }

Kindly guide me on this, where I am gone wrong.

Try This out:

C#

protected void Up_Resume_File_Click(object sender, EventArgs e)
{
    if (Resume_File.PostedFile.FileName!= string.Empty)
    {
        StatusLabel.Text = Yes;
    }
    else
    {
        StatusLabel.Text = No;
    }
}

Your code is correct only. As I guessed, you have taken your file upload control inside the update panel(You can see the same situation here[^]). Remove the update panel and check it again.

Alternative solution:
Add a trigger for UpdatePanel:

ASP.NET

<triggers>
   <asp:postbacktrigger controlid="btnCertificateUpload" />
</triggers>

This will force a postback when the upload button is clicked.

After that add the below line to the Page_Load:

C#

Page.Form.Attributes.Add("enctype", "multipart/form-data");

Hope it helps.!
