这是转换DataGrid显示格式之后 连接字符串的方法 显示:操作人(地点)
public static ObservableCollection<CListModel> AllUserList
{
get
{
if (_AllUserList == null)
{
_AllUserList = new ObservableCollection<CListModel>(); var users = UserDal.GetInstance().GetUserByCondition(new XGX_USER()); foreach (var item in users)
{
StringBuilder sb = new StringBuilder();
sb.Append(item.USER_NAME); if (!string.IsNullOrEmpty(item.USER_PLACE))
{
sb.Append("(");
sb.Append(item.USER_PLACE);
sb.Append(")");
} _AllUserList.Add(new CListModel() { DisplayValue = sb.ToString(), SelectValue = item.USER_ID });
}
}
return _AllUserList;
}
}
另一种简单的方法:
public const string SQL_SELECT_XGX_BALANCE =
@"
SELECT
T.ID,
T.SUM,
T.OPERATOR,
(U.USER_NAME || '('||U.USER_PLACE||')') OPERATOR_N, //操作人(地点)
T.OPERATION_TIME,
T.STATUS
FROM
XGX_BALANCE T
LEFT JOIN XGX_USER U
ON T.OPERATOR=U.USER_ID
";
左联 USER表 查出
(U.USER_NAME || '('||U.USER_PLACE||')')
XAML Binding OPERATOR_N
