Hello PPilev,

Using the latest 2011.2 controls.  Here is the method in the user control to convert the DataTable to an Ilist for the data selector and pivot grid:

public void SetFlatDatasource(DataTable dt)
{
    DynamicTypeBuilder typeBuilder = new DynamicTypeBuilder
    {
        DynamicAssemblyName = "MyAssembly",
        DynamicTypeName = "Pane"
    };

    IList properties = new List();

    foreach (DataColumn column in dt.Columns)
    {
        DynamicTypePropertyInfo propertyInfo = new DynamicTypePropertyInfo
        {
            PropertyName = column.ColumnName,
            PropertyType = column.DataType
        };
        properties.Add(propertyInfo);
    }

    Type dynamicType = typeBuilder.GenerateType(properties);
    Type listType = typeof(List<>);
    Type genericListType = listType.MakeGenericType(dynamicType);

    IList list = (IList)Activator.CreateInstance(genericListType);

    foreach (DataRow dataRow in dt.Rows)
    {
        object myDynamicInstance = Activator.CreateInstance(dynamicType);

        foreach (DataColumn column in dt.Columns)
        {
            PropertyInfo propertyVal = dynamicType.GetProperty(column.ColumnName);

            if (dataRow[column] != DBNull.Value)
            {
                propertyVal.SetValue(myDynamicInstance, dataRow[column], null);
            }
        }

        list.Add(myDynamicInstance);
    }

    FlatDataSource flatDataSource = new FlatDataSource()
    {
        ItemsSource = list,
        Cube = DataSourceBase.GenerateInitialCube("Pane"),
        // if you know the names of demensions you want to be in rows and columns you can define them here
        Columns = DataSourceBase.GenerateInitialItems("[Columns]"),
        Rows = DataSourceBase.GenerateInitialItems("[Row]"),
        Measures = DataSourceBase.GenerateInitialItems("Value")
    };

    dataSelector.DataSource = flatDataSource;
    pivotGrid.DataSource = flatDataSource;
}

When you say initialization, do you mean the xaml? If yes, how can we post xaml in this forum? I will say it does not contain anything special. AllowCompactLayout is set to True, Height and Width are set to Auto...there is really nothing noteworthy.

Simple question, should this control perform well with a row count of say 2,000 with 8 columns?
