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 = "";
           }

 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>

 <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;
           }
       }
   }

 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();

            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();
