Hi aruneddy,
Check this example. Now please take its reference and correct your code.
Using the below article i have created the example.
Home.aspx
<asp:Button Text="Send" runat="server" OnClick="Send" />
Home.aspx.cs
protected void Send(object sender, EventArgs e)
{
Response.Redirect("Default.aspx?No=3");
}
Home.aspx.vb
Protected Sub Send(ByVal sender As Object, ByVal e As EventArgs)
Response.Redirect("Default.aspx?No=3")
End Sub
Default.aspx
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script type="text/javascript">
window.onload = function () {
for (var i = 0; i < window.location.search.split('=')[1]; i++) {
var counter = i + 1;
var div = document.createElement('DIV');
div.innerHTML = '<input id="file' + counter + '" name = "file' + counter + '" type="file" /><input id="Button' + counter + '" type="button" value="Remove" onclick = "RemoveFileUpload(this)" />';
document.getElementById("FileUploadContainer").appendChild(div);
counter++;
}
}
function RemoveFileUpload(div) {
document.getElementById("FileUploadContainer").removeChild(div.parentNode);
}
</script>
</head>
<body>
<form id="form1" runat="server" enctype="multipart/form-data" method="post">
<div id="FileUploadContainer">
</div>
<br />
<asp:Button ID="btnUpload" runat="server" Text="Upload" OnClick="btnUpload_Click" />
</form>
</body>
</html>
Default.aspx.cs
protected void btnUpload_Click(object sender, EventArgs e)
{
for (int i = 0; i < Request.Files.Count; i++)
{
HttpPostedFile PostedFile = Request.Files[i];
if (PostedFile.ContentLength > 0)
{
string FileName = System.IO.Path.GetFileName(PostedFile.FileName);
PostedFile.SaveAs(Server.MapPath("Files\\") + FileName);
}
}
}
Default.aspx.vb
Protected Sub btnUpload_Click(ByVal sender As Object, ByVal e As System.EventArgs)
For i As Integer = 0 To Request.Files.Count - 1
Dim PostedFile As HttpPostedFile = Request.Files(i)
If PostedFile.ContentLength > 0 Then
Dim FileName As String = System.IO.Path.GetFileName(PostedFile.FileName)
PostedFile.SaveAs(Server.MapPath("Files\") + FileName)
End If
Next
End Sub
