Add NOV Grid control in MonoMac project at runtime
To get started and host NOV in your Mac OS X (MonoMac) application, take a look at:
Getting Started with NOV in MonoMac project
The following topic shows how to add a NOV Grid Widget (control) in MonoMac project at runtime. We are going to create a Data Table (NMemoryDataTable) with dummy data source and bind the Grid to the this data source.
1. Reference the NOV Assemblies
Ensure that your application references the following NOV dlls:
Nevron.Nov.Presentation.dll - core NOV portable assembly;
Nevron.Nov.Host.MonoMac.dll - presentation host for MonoMac;
MonoMac.dll - make sure to reference the MonoMac.dll that comes with the NOV installation and remove the default one, which is created by Xamarin Studio;
Nevron.Nov.Grid.dll - assembly for the NGridModule;
You can reference the dlls directly from the System/Applications/NevronOpenVision.MonoMac.app/Contents/Bin folder or copy those dlls to a folder which is more convenient for referencing.
2. When initializing the NOV Application, make sure to create the Grid module
Open the Main.cs file and use the following code:
using System;
using Nevron.Nov;
using Nevron.Nov.Mac;
using Nevron.Nov.Grid;
#if UNIFIEDAPI
using Foundation;
using AppKit;
#else
using MonoMac.Foundation;
using MonoMac.AppKit;
#endif
namespace MonoMacApplication1
{
class MainClass
{
static void Main(string[] args)
{
NSApplication.Init();
NLicenseManager.Instance.SetLicense(new NLicense("LICENSE KEY"));
// install NOV
NModule[] modules = new NModule[]
{
// TODO: Create modules here
NGridModule.Instance
};
NNOVApplicationInstaller.Install(modules);
NSApplication.Main(args);
}
}
}
3. Create the Grid (the example uses NTableGrid), data source and bind the Gird to the data source
Open the MainWindow.cs file and use the following code to create the Grid:
using System;
using Nevron.Nov.Mac;
using Nevron.Nov.UI;
using Nevron.Nov;
using Nevron.Nov.Grid;
using Nevron.Nov.Data;
#if UNIFIEDAPI
using Foundation;
using AppKit;
#else
using MonoMac.Foundation;
using MonoMac.AppKit;
#endif
namespace MonoMacApplication1
{
public partial class MainWindow : NSWindow
{
#region Constructors
// Called when created from unmanaged code
public MainWindow(IntPtr handle)
: base(handle)
{
Initialize();
}
// Called when created directly from a XIB file
[Export("initWithCoder:")]
public MainWindow(NSCoder coder)
: base(coder)
{
Initialize();
}
// Shared initialization code
void Initialize()
{
NApplication.ApplyTheme(new NMacElCapitanTheme());
// create a table grid view
NTableGridView view = new NTableGridView();
// Load the data to the grid
LoadData(view);
// create NOV host
this.ContentView = new NNovWidgetHost(view);
}
private void LoadData(NTableGridView view)
{
NTableGrid grid = view.Grid;
grid.DataSource = CreateDummyDataSource();
grid.AlternatingRows = true;
grid.AllowEdit = true;
}
/// <summary>
/// Creates the data source to bind the grid to.
/// </summary>
public static NDataSource CreateDummyDataSource()
{
NMemoryDataTable dataTable = new NMemoryDataTable(new NFieldInfo[]{
new NFieldInfo("EmployeeID", typeof(Int32)),
new NFieldInfo("Name", typeof(String)),
new NFieldInfo("City", typeof(String)),
new NFieldInfo("Birth Date", typeof(DateTime)),
new NFieldInfo("Married", typeof(Boolean))
});
dataTable.AddRow(1, "Nancy Davolio", "Seattle", new DateTime(1968, 12, 8), true);
dataTable.AddRow(2, "Andrew Fuller", "Tacoma", new DateTime(1952, 2, 19), true);
dataTable.AddRow(3, "Janet Leverling", "Kirkland", new DateTime(1963, 8, 30), false);
dataTable.AddRow(4, "Margaret Peacock", "Redmond", new DateTime(1958, 9, 19), false);
dataTable.AddRow(5, "Steven Buchanan", "London", new DateTime(1955, 3, 4), true);
dataTable.AddRow(6, "Michael Suyama", "London", new DateTime(1963, 7, 2), true);
dataTable.AddRow(7, "Robert King", "London", new DateTime(1960, 5, 29), false);
dataTable.AddRow(8, "Laura Callahan", "Seattle", new DateTime(1958, 1, 9), true);
dataTable.AddRow(9, "Anne Dodsworth", "London", new DateTime(1969, 7, 2), false);
return new NDataSource(dataTable);
}
#endregion
}
}
Run the application - it should display a simple Mac window with a Grid bound to the dummy data source.
