ObjectDataSource 数据绑定：在 Select 方法调用之后获取对象属性
我正在使用 ObjectDataSource 控件来调用 MapInfo 对象。该对象有两个属性：
- public IList 访问
- public int TotalAvailable
select 方法返回一个 IList，但也会填充 TotalAvailable 属性。我已将 ObjectDataSource 中的 TypeName 设置为 MapInfo 对象，但因为 Select 方法仅返回 IList，所以我无权访问 TotalAvailable。
[DataObject(true)]
public sealed class MapInfo
{
private IList<Visit> visits;
private int totalCount;
public IList<Visit> Visits
{
get
{
if (visits == null)
visits = new List<Visit>();
return visits;
}
set
{
visits = value;
}
}
[DataObjectMethod(DataObjectMethodType.Select)]
public IList<Visit> GetAccountVisits(DateTime startdate, DateTime enddate, string orgids, int reportlevel,
string username, int authlevel, bool visited, bool notvisited, string accounttypeid)
{
有
什么方法可以访问这个值。我知道它正在填充到 MapInfo 对象中，但从 Select 方法返回的所有内容都是 IList
I am using an ObjectDataSource control to call a MapInfo object. This object has two properties:
- public IList Visits
- public int TotalAvailable
The select method returns an IList but the TotalAvailable property is also populated. I have set the TypeName in the ObjectDataSource to the MapInfo object but because the Select method only returns the IList I don't have access to the TotalAvailable.
[DataObject(true)]
public sealed class MapInfo
{
private IList<Visit> visits;
private int totalCount;
public IList<Visit> Visits
{
get
{
if (visits == null)
visits = new List<Visit>();
return visits;
}
set
{
visits = value;
}
}
[DataObjectMethod(DataObjectMethodType.Select)]
public IList<Visit> GetAccountVisits(DateTime startdate, DateTime enddate, string orgids, int reportlevel,
string username, int authlevel, bool visited, bool notvisited, string accounttypeid)
{
}
Is there any way to access this value. I know it is being populated in the MapInfo object but all that gets returned from the Select method is the IList

该数据源在选择发生后触发 Selected 事件；您可以尝试查看它是否公开了根对象。
HTH。
that datasource fires a Selected event after the select happens; you could try to see if it exposes the root object there.
HTH.
我已将 SelectMethod 的返回类型更改为：
在 CreateChildControls 方法中的 CompositeDataBoundControl 中，然后我使用：
不过，我会欣赏更优雅的解决方案。
I have changed the return type of the SelectMethod to:
In my CompositeDataBoundControl in the CreateChildControls method, I then use:
Would appreciate a more elegant solution though.
