通过ItemDataBound事件操作数据控件中嵌套的其他控件

首先，需要在控件中声明ItemDataBound事件。

其次，在code文件中实现事件。

再次，代码示例如下。

<span style="font-size:14px;">protected void rptPhoto_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
            if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
            {
                LinkButton lblPRO = e.Item.FindControl("lbtnPro") as LinkButton;
                Label lbState = e.Item.FindControl("Label1") as Label;

                    if (lbState.Text == "-1")
                    {
                        lblPRO.Visible = true;
                    }
            }
        }</span>

protected void rptPhoto_ItemCommand(object sender, RepeaterCommandEventArgs e)
        {
            Literal litPhotoID = (Literal)e.Item.FindControl("litPhotoID");
            Literal PhotoFilePathFlag = (Literal)e.Item.FindControl("PhotoFilePathFlag");
            Literal PhotoFileName =(Literal)e.Item.FindControl("PhotoFileName");
            int photoID = Convert.ToInt32(litPhotoID.Text);

            switch (((LinkButton)e.CommandSource).CommandName)
            {
                case "Pro":
                    Response.Redirect("/manage/gallery/SaleAuditInfo.aspx?photoid=" + photoID + "&pname=" + PhotoFileName + "&pflag=" + PhotoFilePathFlag);
                    break;
                case "Edit":
                    Response.Redirect("/manage/gallery/ProductRelationModify.aspx?photoid=" + photoID);
                    break;
                case"Content":
                    Response.Redirect("/manage/gallery/ContentModify.aspx?photoid=" + photoID);
                    break;
                case "Others":
                    Response.Redirect("/manage/gallery/OtherContentModify.aspx?photoid=" + photoID);
                    break;
                case "":

                    break;
            }
        }

<ItemTemplate>

<td class="itemtd" style="200px;">

       <asp:LinkButton ID="lbtnPro" runat="server" Text="审核 |" CommandName="Pro" Visible="false"></asp:LinkButton>

      <asp:LinkButton ID="lbtnEdit" runat="server" Text="修改类别 |" CommandName="Edit" Visible="false"></asp:LinkButton>

      <asp:LinkButton ID="lbtnContent" CommandName="Content" runat="server">商品详情 |</asp:LinkButton>
