1.获取表头数据源动态生成DataGrid表头
DataGridTextColumn d = new DataGridTextColumn();
d.Header = itemPriceClass.PriceKindCode + itemPriceClass.PriceKindName;
Binding bin = new Binding();
bin.Converter = new RowIndexConverter();
bin.ConverterParameter = itemPriceClass.PriceKindCode;
d.Binding = bin;
d.CanUserSort = false;
d.FontSize = 13;
d.IsReadOnly = true;
dgList.Columns.Add(d);
注：其中Binding这一段是对该列的数据绑定处理的，由于数据源是Dictionary中获取，所以要对数据显示部分进行处理。
public class RowIndexConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
Row row = value as Row;
string index = parameter as string;
return row[index];
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
}
注：最终DataGrid的数据源部分就是List<Row>
public class Row
{
Dictionary<string, object> dictionary = new Dictionary<string, object>();
public object this[string index]
{
get { if (dictionary.ContainsKey(index)) { return dictionary[index]; } else { return 0; } }
set { dictionary[index] = value;}
}
}
2.对数据源进行处理
得到的数据源格式
inpareaname pricekindname realcost pricekindcode
A ca 100 101
A ba 150 102
B da 100 104
注：pricekindname就是表头显示的数据
private List<Row> CreateDataGridColumn()
{
List<Row> result = new List<Row>();
if (itemPriceClassList != null && itemPriceClassList.Count > 0)
{
if (wardExpenseDetailByPriceItemClassList != null && wardExpenseDetailByPriceItemClassList.Count > 0)
{
foreach (WardExpenseDetailByPriceItemClass detail in wardExpenseDetailByPriceItemClassList)
{
if (result.Count > 0)
{
bool flag = false;
foreach (Row r in result)
{
if (r["AreaName"].ToString() == detail.InpAreaName)
{
r[detail.PriceKindCode] = detail.RealCost;
flag = true;
break;
}
}
if (!flag)
{
Row row = new Row();
row["AreaName"] = detail.InpAreaName;
row[detail.PriceKindCode] = detail.RealCost;
result.Add(row);
}
}
else
{
Row row = new Row();
row["AreaName"] = detail.InpAreaName;
row[detail.PriceKindCode] = detail.RealCost;
result.Add(row);
}
}
}
}
rowDataList = result;
return result;
}
注：还有一种解决方案---未测试
1.在silverlight的service层中动态生成实体类，其中属性为表头的值，service层动态拼接成List<T>传到client端。
注：object类型传到client端会出错的。
