Printable View
Hi,
In my ASP.NET Webform page, I have a fileuploader and a div. On single selection of image, the selected image is added to the div. All works fine. Now, I would like to add a checkbox or some sort of selection and then save the selected images to the server folder. Please can someone help on how to do it?
Thanks
try this code:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs"Inherits="Byte_array_gridview._Default" %>

<head id="Head1" runat="server">

</head>
<body>
<form id="form1" runat="server">
<div>
<tr>
<td>
Image File </td>
<td>
<input id="Upload" type="file" runat="server" /></td>
</tr>
</table>
<asp:Button id="btn_insert" RunAt="server"
Text="Insert" onclick="btn_insert_Click"></asp:Button>
<asp:label id="lblMessage" runat="server" />
</div>
</form>
</body>
</html>
