<h2>
Simple Upload with Progress (Custom Validation)
</h2>
<p>
A sample demonstrating how to create user-defined validation functions for an upload
control. In this example, we defined two validation rules:</p>
<ul>
<li>Maximum file size: 100K</li><li>Allowed file types: jpeg, jpg, gif,png </li>
</ul>
<p>
Click the following button to upload.
</p>
<CuteWebUI:Uploader runat="server" ID="Uploader1" InsertText="Upload">
<ValidateOption AllowedFileExtensions="jpeg,jpg,gif,png" MaxSizeKB="100" />
</CuteWebUI:Uploader>
<br />
<br />
