Hi,

Due to current limitation of DataGrid it's not easy to do so. You can try following code:

 

xaml.cs:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Net;

using System.Windows;

using System.Windows.Controls;

using System.Windows.Documents;

using System.Windows.Input;

using System.Windows.Media;

using System.Windows.Media.Animation;

using System.Windows.Shapes;

using System.Reflection.Emit;

using System.Reflection;

namespace SilverlightApplication1

{

public partial class Page : UserControl

{

public Page()

{

InitializeComponent();

this.Loaded += new RoutedEventHandler(Page_Loaded);

}

static Random r = new Random();void Page_Loaded(object sender, RoutedEventArgs e)

{

//init array

int[,] array = new int[5, 7];for (int i = 0; i < 5; i++)

{

for (int j = 0; j < 7; j++)

{

array[i, j] = r.Next(1, 100);

}

}

this.DataGrid1.ItemsSource = new DataSource_TwoDimensionArray<int>(array);

}

}

public class DataSource_TwoDimensionArray<T> : List<object>

{

private Type finished;

private int counter=0;

private void Emit(T[,] array)

{

AppDomain myDomain = AppDomain.CurrentDomain;

AssemblyName myAsmName = new AssemblyName("MyAssembly");

AssemblyBuilder myAssembly = myDomain.DefineDynamicAssembly(myAsmName, AssemblyBuilderAccess.Run);

ModuleBuilder myModule = myAssembly.DefineDynamicModule(myAsmName.Name);

TypeBuilder myType = myModule.DefineType("DataSource", TypeAttributes.Public);

 

for (int j = 0; j <= array.GetUpperBound(1); j++)

{

Type properyType = typeof(T);

FieldBuilder exField = myType.DefineField("_" + "columnName" + counter, properyType, FieldAttributes.Private);

PropertyBuilder exProperty = myType.DefineProperty("columnName" + counter, PropertyAttributes.None, properyType, Type.EmptyTypes);

//Get

MethodBuilder exGetMethod = myType.DefineMethod("get_" + "columnName"+counter, MethodAttributes.Public, properyType, Type.EmptyTypes); ILGenerator getIlgen = exGetMethod.GetILGenerator();

//IL for a simple getter:

//ldarg.0

//ldfld int32 SilverlightClassLibrary1.Class1::_Age

//ret

getIlgen.Emit(OpCodes.Ldarg_0);

getIlgen.Emit(OpCodes.Ldfld, exField);

getIlgen.Emit(OpCodes.Ret);

exProperty.SetGetMethod(exGetMethod);

//Set

MethodBuilder exSetMethod = myType.DefineMethod("set_" + "columnName" + counter, MethodAttributes.Public, null, new Type[] { properyType }); ILGenerator setIlgen = exSetMethod.GetILGenerator();

//IL for a simple setter:

//ldarg.0

//ldarg.1

//stfld int32 SilverlightClassLibrary1.Class1::_Age

//ret

setIlgen.Emit(OpCodes.Ldarg_0);

setIlgen.Emit(OpCodes.Ldarg_1);

setIlgen.Emit(OpCodes.Stfld, exField);setIlgen.Emit(OpCodes.Ret);

exProperty.SetSetMethod(exSetMethod);

//counter++

counter++;

 

}

 

finished = myType.CreateType();

 

}

 

public DataSource_TwoDimensionArray(T[,] array)

{

Emit(array);

AddPrivate(array);

}

private void AddPrivate(T[,] array)

{

 

int _count = 0;for (int i = 0; i<= array.GetUpperBound(0); i++)

{

 

object item = Activator.CreateInstance(finished);for (int j = 0; j <= array.GetUpperBound(1); j++)

{

string propertyname = "columnName" + _count;

MethodInfo method = finished.GetMethod("set_" + propertyname);method.Invoke(item, new object[] { array[i,j] });

_count++;

}

_count = 0;

base.Add(item);

}

 

}

 

}

}

xaml:

<data:DataGrid x:Name="DataGrid1"></data:DataGrid>
