设置repeater每行多少个的方法

前台代码：

<asp:ScriptManagerProxy ID="ScriptManagerProxy1" runat="server"></asp:ScriptManagerProxy>

<asp:UpdatePanel ID="UpdatePanel1" runat="server">

    <ContentTemplate>

        <div style="width: 350px; float: left;">

            <asp:Literal ID="litVideo" runat="server"></asp:Literal><br />

            <asp:Repeater runat="server" ID="rptVideoName" OnItemDataBound="rptVideoName_ItemDataBound" OnItemCommand="rptVideoName_ItemCommand">

                <ItemTemplate>

                    <asp:LinkButton ID="lbVideoName" runat="server" Text='<%# DataBinder.Eval(Container.DataItem,"Title")%>' CommandName="PlayVideo" CommandArgument='<%# DataBinder.Eval(Container.DataItem,"ID")%>'></asp:LinkButton>

                </ItemTemplate>

            </asp:Repeater>

        </div>

    </ContentTemplate>

</asp:UpdatePanel>

后台代码：

//绑定repeater的个数，每行3个

protected void rptCategories_ItemDataBound(object src, RepeaterItemEventArgs e)

        {

            // Add <tr> for change row

            if ((e.Item.ItemIndex + 1) % 3 == 0)

            {

                e.Item.Controls.Add(new LiteralControl("</tr><tr>"));

            }

        }

//repeater相应单击事件

protected void rptVideoName_ItemCommand(object sender, RepeaterCommandEventArgs e)

        {

            if (e.CommandName == "PlayVideo")

            {

                BindVideoName();

                SPQuery query = new SPQuery();

                SPList list = SPContext.Current.Web.Lists[ListNames.CompanyPublicityVideo];

                SPListItem item = (new SharePointService()).GetItem(list, int.Parse(e.CommandArgument.ToString()));

                this.litVideo.Text = PlayVideo(item.Folder, "autoplay=''");

            }

        }
