使用Repeater定制n行m列的数据邦定表

通过定制n行m列的数据表而不是常用的n行1列数据表可以有效利用页面空间，下面是一个例子：

        <asp:Repeater ID="roleList" runat="server" OnItemDataBound="roleList_ItemDataBound">
            <HeaderTemplate>
                <table class="Listing_table" border="0" cellpadding="0" cellspacing="0" align="center" width="100%">
            </HeaderTemplate>
            <ItemTemplate>
                <asp:Literal id="beginRow" runat="server" />
                    <td valign="top" id="tableColumn" runat="server">
                        <div class="listContainer">
                            <asp:Literal ID="roleName" runat="server" />
                        </div>
                    </td>
                <asp:Literal id="endRow" runat="server" />
            </ItemTemplate>
            <FooterTemplate>
                </table>
            </FooterTemplate>
        </asp:Repeater>

public int ListingRows
    {
        get
        {
            Object state = ViewState["ListingRows"];
            if (state != null)
            {
                return (int)state;
            }
            return 3;
        }
        set
        {
            ViewState["ListingRows"] = value;
        }
    }
    public int ListingColumns
    {
        get
        {
            Object state = ViewState["ListingColumns"];
            if (state != null)
            {
                return (int)state;
            }
            return 3;
        }
        set
        {
            ViewState["ListingColumns"] = value;
        }
    }

    private int columnCount = 0;
    private int rowCount = 0;
    private int totalColumns = 0;
    private bool totalColumnsFound = false;
    private int totalRecords = 0;

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            this.BindRoleList();
        }
    }

    protected void roleList_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        PRole pRole = e.Item.DataItem as PRole;

        if (pRole != null)
        {
            switch (e.Item.ItemType)
            {
                case ListItemType.Item:
                case ListItemType.AlternatingItem:

                    //角色名
                    Literal roleName = (Literal)e.Item.FindControl("roleName");
                    roleName.Text = pRole.RoleName;

                    //设置列数
                    HtmlTableCell tableColumn = e.Item.FindControl("tableColumn") as HtmlTableCell;
                    if (tableColumn != null)
                        tableColumn.Width = (100 / ListingColumns).ToString() + "%";

                    //Begin a column, if necessary
                    if (columnCount == 0)
                    {
                        Literal beginRow = (Literal)e.Item.FindControl("beginRow");
                        beginRow.Text = "<tr>";
                    }
                    columnCount++;
                    if (!totalColumnsFound)
                        totalColumns++;

                    //End a column, if necessary
                    if ((columnCount == ListingColumns) || ((rowCount * ListingColumns + columnCount) == totalRecords))
                    {
                        Literal endRow = (Literal)e.Item.FindControl("endRow");
                        endRow.Text = "</tr>";
                        columnCount = 0;
                        totalColumnsFound = true;
                        rowCount++;
                    }

                    break;
            }
        }

    }

    private void BindRoleList()
    {
        List<PRole> pRoles = GetDataSource();
        totalRecords = pRoles.Count;

        roleList.DataSource = pRoles;
        roleList.DataBind();
    }

    private List<PRole> GetDataSource()
    {
        Guid applictionId = new Guid("7cdbbdea-7b31-42cc-b920-f7a034062063");

        IPRole iPRole = ObjectFactory.CreateIPRole();
        List<PRole> pRoles = iPRole.GetPRoles(applictionId);

    }

分页状态下的使用：

    <div>
        <asp:Repeater ID="roleList" runat="server" OnItemDataBound="roleList_ItemDataBound">

            </HeaderTemplate>
            <ItemTemplate>
                <asp:Literal id="beginRow" runat="server" />
                    <td valign="top" id="tableColumn" runat="server">
                        <div class="listContainer">
                            <asp:Literal ID="roleName" runat="server" />
                        </div>
                    </td>
                <asp:Literal id="endRow" runat="server" />
            </ItemTemplate>
            <FooterTemplate>
