Image preview after upload in asp.net

Introduction: In this article today I will explain how we can preview the image after uploading in asp.net.

Description:


Add a webform to project and design the page as shown below:

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
    <center>
   <fieldset style="width:25%">
   <legend>Uplaod and Preview the Image</legend>
   <table>
   <tr><td>Upload Image:</td><td><asp:FileUpload ID="FileUpload1" runat="server" /><br />
       <asp:Label ID="lblmessage" runat="server"></asp:Label></td></tr>
   <tr><td></td><td> <asp:Button ID="btnupload" runat="server" Text="Upload Image"
           onclick="btnupload_Click" /></td></tr>
   </table>        
       <asp:Image ID="imgpreview" runat="server" width="350px" Height="300px"/>
   </fieldset>

   </center>
    </div>
    </form>
</body>
</html>

On button click write the below given code (C#):

   protected void btnupload_Click(object sender, EventArgs e)
        {
            if (FileUpload1.HasFile)
            {
                string path = Server.MapPath("~/Images/") + FileUpload1.FileName;
                FileUpload1.SaveAs(path);
                imgpreview.ImageUrl = "~/Images/" + FileUpload1.FileName;
            }
            else
            {
                lblmessage.Text = "Upload image";
                imgpreview.ImageUrl = "";
            }
        }

In VB:

Protected Sub btnupload_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnupload.Click
        Dim path As String
        If FileUpload1.HasFile Then
            path = Server.MapPath("~/images/") + FileUpload1.FileName
            FileUpload1.SaveAs(path)
            imgpreview.ImageUrl = "~/images/" + FileUpload1.FileName
        Else
            lblmessage.Text = "Upload Image"
            imgpreview.ImageUrl = ""
        End If

    End Sub


Build and run the project.

Output:
