    We are using RadUpload component with standard html input control. We have several controls that cause postback to the server on a form. And it is needed to upload file only when you press exact button, like upload button. But now it will try to upload file on every postback. How it can be fixed?

    Example of usage:
    <input type="file" runat="server">
    <telerik:RadProgressManager ID="progressManager" runat="server" />
    <telerik:RadProgressArea ID="progressArea" runat="server">

    Hello Jochem Nuij,

    This can be easily achieved using RadUpload instead of <input type="file">
    Please check the implementation in this help article:
    Preventing Uploads

    If you want RadUpload to look like the standard input type="file" you can set its EnableFileInputSkinning to false and ControlObjectsVisibility to None.
