File Dialogs Customization

In This Topic

NOV Diagram makes it easy to customize the file formats shown in its "Open" and "Save As" dialogs. To do that, you should:

1. Create Custom Open and Save As Command Actions

Create custom classes that inherit from NOpenCommandAction and NSaveAsCommandAction and override the GetFormats method to return only the drawing file formats you want to show in the "Open" and "Save As" file dialogs.

For example, the following custom commands will show only the Visio Drawing (VSDX) and AutoCAD Drawing Interchange (DXF) file formats:

private class CustomOpenCommandAction : NOpenCommandAction { public CustomOpenCommandAction() { } static CustomOpenCommandAction() { CustomOpenCommandActionSchema = NSchema.Create(typeof(CustomOpenCommandAction), NOpenCommandActionSchema); } protected override NDrawingFormat[] GetFormats() { return new NDrawingFormat[] { NDrawingFormat.Visio, NDrawingFormat.VectorAutoCadDxf }; } public static readonly NSchema CustomOpenCommandActionSchema; }

    }
    static CustomOpenCommandAction()
    {
        CustomOpenCommandActionSchema = NSchema.Create(typeof(CustomOpenCommandAction), NOpenCommandActionSchema);
    }

    protected override NDrawingFormat[] GetFormats()
    {
        return new NDrawingFormat[]
        {
            NDrawingFormat.Visio,
            NDrawingFormat.VectorAutoCadDxf
        };
    }

    public static readonly NSchema CustomOpenCommandActionSchema;
}

    static CustomSaveAsCommandAction()
    {
        CustomSaveAsCommandActionSchema = NSchema.Create(typeof(CustomSaveAsCommandAction), NSaveAsCommandActionSchema);
    }

    protected override NDrawingFormat[] GetFormats()
    {
        return new NDrawingFormat[]
        {
            NDrawingFormat.Visio,
            NDrawingFormat.VectorAutoCadDxf
        };
    }

    public static readonly NSchema CustomSaveAsCommandActionSchema;
}

2. Replace the Old "Open" and "Save As" Command Actions

Use the following code to replace the old "Open" and "Save As" command actions of the drawing view with the new custom ones:
