DataList和Repeat无数据时提示暂无数据几种方法

1.放一个label

 

 DataTable table = new DataTable(); 
            repeater1.DataSource = table; 
            repeater1.DataBind(); 
            if (table.Rows.Count == 0)//或者 repAcctLedger.Items.Count == 0 
            { 
                label1.Text = "暂无查询结果"; 
            } 
            else 
            { 
                label1.Text = ""; 
            }

 

2.在FooterTemplate模板中放一个label

 <FooterTemplate>
    <td style="height: 16px">
         <asp:Label ID="Label1" runat="server" Text="暂无检索记录!" Visible="false"></asp:Label>
         </td>
    </FooterTemplate>

 

 

 protected void rpSearch_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.ItemType==ListItemType.Footer)
        {
            if (rpSearch.Items.Count<=0)
            {
                ((Label)e.Item.FindControl("Label1")).Visible = true;
            }
        }
    }

 

第三种:在DataTable加一行数据.

 

            if (table.Rows.Count == 0)//或者 repAcctLedger.Items.Count == 0 
            { 
                    DataRow dr = dt.NewRow(); 
                    dr[0] = "无数据"; 
                    dt.Rows.Add(dr); 
            } 
            repeater1.DataSource = table; 
            repeater1.DataBind();
