请教高手，怎么将泛型 Collection<T> 绑定到 GridView

Question

调用一个方法返回Collection<T>的类型，绑定到GridView后却只能显示第一条的数据，怎样才能使GridView能显示Collection<T>中全部的数据呢？GridView1.DataSource = Collection<T>;
GridView1.DataBind();或者谁能说一下，DataBind的机制呢？

Answer 1

protected void odsYcfswkList_Selected(object sender, ObjectDataSourceStatusEventArgs e)
    {
        IList<db.Ycfswk> list = e.ReturnValue as IList<db.Ycfswk>;
if (list == null)
Pager1.Records = 0;
else
Pager1.Records = list.Count;
    }

Answer 2

such as public class Persion {
   // ...
   public string FirstName {
      get { return _firstName; }
   }
   
   // ...
   // here Company is another entity type
   public Company Company {
       get { return _company; }
   }}ICollection persions;
//persions = new Persion[] { persion1, persion2 };
// or
persions = new ArrayList();
persions.Add(persion1);
persions.Add(persion2);
/* if you under .net 2.0, had better take as following:
 * IList<Persion> perions = new List<Persion>();
 * persions.Add(persion1);
 * persions.Add(persion2);
*/
GridView1.DataSource = persions;
GridView1.DataBind();    <asp:GridView ID="GridView1" runat="server">
        <Columns>
            <asp:BoundField DataField="FirstName"></asp:BoundColumn>
            <asp:TemplateField>
                <ItemTemplate>
                    <asp:Label ID="Label1" Text='<%# Eval("Company.Name") %>' runat="server"></asp:Label>
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>
Good Luck!

Answer 3

BTW, if your element in the collection is primary type such as int, double, string...
take as below:
ICollection<string> strColl = new Collection<string>();
strColl[0]= "hello";
strColl[1]= "world";GridView1.DataSource = strColl;
GridView1.DataBind();    <asp:GridView ID="GridView1" runat="server">
        <Columns>
            <asp:BoundField DataField="FirstName"></asp:BoundColumn>
            <asp:TemplateField>
                <ItemTemplate>
                    <%# Container.DataItem %>
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>Hope helpful!
