How do I disable the web part export option?

Question

I have the requirement to not allow users to export my custom web part.

How do I disable/hide the Export menu option?

Answer 1

See the WebPartExportMode Enum. You will set this enum when adding the user control to the page. You can allow no properties to be exported.

<aspSample:TextDisplayWebPart 
        runat="server"   
        id="textwebpart" 
        title = "Text WebPart" 
        ExportMode="None" 
        />

Answer 2

@Tim's answer was what I needed. I ended up using an override and I have a Web Part Property (WPPAllowExport) that controls whether or not to allow the export.

public override System.Web.UI.WebControls.WebParts.WebPartExportMode ExportMode
{
    get
    {
        if (WPPAllowExport)
        {
            return base.ExportMode;
        }
        return System.Web.UI.WebControls.WebParts.WebPartExportMode.None;
    }
    set
    {
        if (WPPAllowExport)
        {
            base.ExportMode = value;
        }
        else
        {
            base.ExportMode = System.Web.UI.WebControls.WebParts.WebPartExportMode.None;
        }
    }
}
