ASP.NET中Repeater的Repeater1_ItemDataBound事件

Question

1。首先我用datatable作为了数据源绑定Repeater
  <asp:Repeater ID="Repeater1" runat="server" 
                    onitemdatabound="Repeater1_ItemDataBound">
                <HeaderTemplate>
                <table width="80%" height="80%">
                </HeaderTemplate>
                <ItemTemplate>
                <tr>
                <td>
                    <asp:Label ID="lblText" runat="server" Text="&nbsp;"></asp:Label>
                </td>
                </tr>
                </ItemTemplate>
                <FooterTemplate>
                </table>
                </FooterTemplate>
                </asp:Repeater>    private void Bind() 
    {
        if (!string.IsNullOrEmpty(txtSearch.Text))
        {
            var newTest = dt.AsEnumerable().Select(p => p.Field<string>("Directions").Contains(txtSearch.Text));
            Repeater1.DataSource = newTest;
            Repeater1.DataBind();
        }
    }在事件中我想让DataTable中的值遍历到Lable中，请看protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            DataRowView rowItem = e.Item.DataItem as DataRowView;
             if (rowItem != null)
            {
                Label lblTest = e.Item.FindControl("lblText") as Label;
                lblTest.Text = Convert.ToString(rowItem["列名"]);
            }
        }
    }lblTest.Text书中为空值，调试的时候DataTable 是有4列的， 我让在ItemDataBound中取出数据.

怎么没人知道呢 CSDN的诸位大神们

Answer 2

<asp:Label ID="lblText" runat="server" Text="&nbsp;"><%#Eval("列名")%></asp:Label>你的Repeater1_ItemDataBound里面，完全没有对表进行遍历什么的，如何可能绑定？

Answer 3

直接在前台绑定就可以了
<asp:Label ID="lblText" runat="server" Text='<%# Eval("列名") %>'></asp:Label>

Answer 4

public  DataTable dt;
    protected void Page_Load(object sender, EventArgs e)
    {
        Show();
        if (!IsPostBack)
        {
            
            Bind();
        }
    }

public void Show() 
    {
        dt = new DataTable();
        DataColumn cdId = new DataColumn("ID");
        dt.Columns.Add(cdId);
        DataColumn cdName = new DataColumn("Name");
        dt.Columns.Add(cdName);
        DataColumn cdDirections = new DataColumn("Directions");
        dt.Columns.Add(cdDirections);
        DataColumn cdPiPei = new DataColumn("PiPei");
        dt.Columns.Add(cdPiPei);
        DataRow dr = dt.NewRow();
        dr["ID"] = "1";
        dr["Name"] = "小明";
        dr["Directions"] = "贾君鹏你妈叫你回家吃饭了";
        dr["PiPei"] = "XM";
        dt.Rows.Add(dr);
        DataRow dr1 = dt.NewRow();
        dr1["ID"] = "2";
        dr1["Name"] = "郭强";
        dr1["Directions"] = "郭强你妈叫你回家吃饭了";
        dr1["PiPei"] = "XM";
        dt.Rows.Add(dr1);
        DataRow dr2 = dt.NewRow();
        dr2["ID"] = "3";
        dr2["Name"] = "赵强";
        dr2["Directions"] = "赵强你妈叫你回家吃饭了";
        dr2["PiPei"] = "XM";
        dt.Rows.Add(dr2);
        DataRow dr3 = dt.NewRow();
        dr3["ID"] = "4";
        dr3["Name"] = "王宏";
        dr3["Directions"] = "王宏你妈叫你回家吃饭了";
        dr3["PiPei"] = "XM";
        dt.Rows.Add(dr3);
    }
