Is your issue resolved ?

Hi Harry,

You can try ClientIDMode="static" for you fileupload control.

Replace Page Load event to

protected void Page_Load(object sender, EventArgs e)
{
this.Page.Form.Enctype = "multipart/form-data";
}

Hi,

Thank you for the reply.

I am already using the if(FileUpload1.HasFile) condition.

sample Code:

protected void btnTenderDocUpload_OnClick(object sender, EventArgs e)

{

string filepath = "",filename="";

DataTable dt = new DataTable();

dt.Columns.Add("ID");

dt.Columns.Add("DocPath");

if (fileUpTenderDoc.HasFile)

{

if (Session["TenderDocs"] == null)

{

filename = DateTime.Now.Second + fileUpTenderDoc.PostedFile.FileName;

DataRow dr = dt.NewRow();

dr["ID"] = "~/TenderDocs/" + filename;

dr["DocPath"] = fileUpTenderDoc.PostedFile.FileName;

filepath = Server.MapPath("~/TenderDocs/" + filename);

fileUpTenderDoc.SaveAs(filepath);

hdntenderFilePath.Value = "~/TenderDocs/" + filename;

//chkFileup.Visible = true;

//chkFileup.Checked = true;

//chkFileup.Text = filename;

dt.Rows.Add(dr);

Session["TenderDocs"] = dt;

gvTenderDocs.DataSource = dt;

gvTenderDocs.DataBind();

}

else

{

DataTable newdt = new DataTable();

newdt = (DataTable)Session["TenderDocs"];

filename = fileUpTenderDoc.PostedFile.FileName;

var rows = newdt.Select("DocPath LIKE '" + filename + "'");

foreach (var row in rows)

row.Delete();

DataRow dr = newdt.NewRow();

dr["ID"] = "~/TenderDocs/" + DateTime.Now.Second + fileUpTenderDoc.PostedFile.FileName;

dr["DocPath"] = fileUpTenderDoc.PostedFile.FileName;

newdt.Rows.Add(dr);

Session["TenderDocs"] = newdt;

Session["TenderDocsSession"] = newdt;

gvTenderDocs.DataSource = newdt;

gvTenderDocs.DataBind();

}

}

else if (FileUpload1.HasFile)

{

//FileUpload1.HasFile

if (Session["TenderDocs"] == null)

{

filename = DateTime.Now.Second + fileUpTenderDoc.PostedFile.FileName;

DataRow dr = dt.NewRow();

dr["ID"] = "~/TenderDocs/" + filename;

dr["DocPath"] = fileUpTenderDoc.PostedFile.FileName;

filepath = Server.MapPath("~/TenderDocs/" + filename);

fileUpTenderDoc.SaveAs(filepath);

hdntenderFilePath.Value = "~/TenderDocs/" + filename;

//chkFileup.Visible = true;

//chkFileup.Checked = true;

//chkFileup.Text = filename;

dt.Rows.Add(dr);

Session["TenderDocs"] = dt;

gvTenderDocs.DataSource = dt;

gvTenderDocs.DataBind();

}

else

{

DataTable newdt = new DataTable();

newdt = (DataTable)Session["TenderDocs"];

filename = fileUpTenderDoc.PostedFile.FileName;

var rows = newdt.Select("DocPath LIKE '" + filename + "'");

foreach (var row in rows)

row.Delete();

DataRow dr = newdt.NewRow();

dr["ID"] = "~/TenderDocs/" + DateTime.Now.Second + fileUpTenderDoc.PostedFile.FileName;

dr["DocPath"] = fileUpTenderDoc.PostedFile.FileName;

newdt.Rows.Add(dr);

Session["TenderDocs"] = newdt;

Session["TenderDocsSession"] = newdt;

gvTenderDocs.DataSource = newdt;

gvTenderDocs.DataBind();

}

}

else

{

//chkFileup.Visible = false;

}

gvTenderDocs.Focus();

}

But i am always getting HasFile as False.

Hello

This is possible in single case that you are not getting file, otherwise there should not be any problem with the code

You can simply write like this :
if (FileUpload1.HasFile)
    // Save file logic
else
    // Alert message
For complete reference, pls follow given link :

Let me know if you stuck somewhere

Thanks
