如何动态将ASP.NET中继器控件绑定到DataSource

Question

我有一个页面，简单下拉目和转发器控件在页面上.on提交中继器控件绑定到具有3列的DataSource1。

现在我的要求是如果我选择选项2，它应该绑定到包含4列的DataSource2。

<asp:Repeater ID="Repeater1" runat="server" OnItemDataBound="Repeater1_ItemDataBound">
<HeaderTemplate>
    <tr>
        <th align="left">Header1</th>
        <th align="left">Header3</th>
        <th align="left">Header2</th>
    </tr>
</HeaderTemplate>
<ItemTemplate>
    <tr>
        <td>
            <asp:Label ID="Header1" runat="server" /></td>
        <td>
            <asp:Label ID="Header3" runat="server" /></td>
        <td>
            <asp:Label ID="Header2" runat="server" /></td>
    </tr>
</ItemTemplate>

.

是相同的转发器可以动态绑定到异构数据源吗？如何在运行时指定标题模板和项目模板？可以只用一个中继器控制和多个异构数据源来实现这种情况吗？

感觉下面的代码会帮助您。

<asp:Repeater ID="Repeater1" runat="server" OnItemDataBound="Repeater1_ItemDataBound">
    <HeaderTemplate>
        <tr class="">
            <asp:Repeater ID="Header1" runat="server">
                <ItemTemplate>
                    <th align="left"><%# Container.DataItem %>
                    </th>
                </ItemTemplate>
            </asp:Repeater>
        </tr>
    </HeaderTemplate>
    <ItemTemplate>
        <tr class="">
            <asp:Repeater ID="Item1" runat="server">
                <ItemTemplate>
                    <td><%# Container.DataItem %>
                    </td>
                </ItemTemplate>
            </asp:Repeater>
        </tr>
    </ItemTemplate>
</asp:Repeater>


protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e) 
    {
        if (e.Item.ItemType == ListItemType.Header)
        {
            Repeater headerRepeater = e.Item.FindControl("Header1") as Repeater;
            headerRepeater.DataSource = dt.Columns;
            headerRepeater.DataBind();
        }

       if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            Repeater columnRepeater = e.Item.FindControl("Item1") as Repeater;
            var row = e.Item.DataItem as System.Data.DataRowView;
            columnRepeater.DataSource = row.Row.ItemArray;
            columnRepeater.DataBind();
        }
    }

.

或以其他方式使用2个不同的用户控件.First用户控件包含Repeater1，第二个包含Repeater2.Then Dynamic将这些中继器添加到您的页面，在

后面的代码

你可以简单地用这样用 -

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
   using (SqlConnection con = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["RBConnectionString"].ConnectionString))
   {
      SqlCommand cmd = new SqlCommand("select * from Customers", con);
      cmd.CommandType = CommandType.StoredProcedure;
      SqlDataAdapter adpt = new SqlDataAdapter(cmd);
      DataTable dt = new DataTable();
      adpt.Fill(dt);
      repeaterObj.DataSource = dt;
      repeaterObj.DataBind();
      cmd.Dispose();
    }
 }

.

Answer 3

尝试设置autopostback= true在dropdownlist上。然后，在Codebehind安装程序上有一个“SelectedIndexchanged”事件处理程序，以读取该值并相应地设置数据源，类似于以下内容：

repeater1.DataSource=<yourdatasource>
repeater1.DataBind()

.

如果您的数据源始终使用相同的列表为您的演示文稿，那么这不应该是一个问题。如果您的数据源将在他们返回的数据列中有所不同，那么Kashif在您的问题中的评论可能对您有所帮助。否则，您只需要填写上面的逻辑，以将转发器的DataSource属性设置为您的数据源是什么...

希望这有助于

使用Bootstrap和DataTables.net插件

protected void rptReport_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
            if (e.Item.ItemType == ListItemType.Header)
            {
                Repeater headerRepeater = e.Item.FindControl("Header1") as Repeater;
                headerRepeater.DataSource = dtOrder.Columns;
                headerRepeater.DataBind();
            }

            if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
            {
                Repeater columnRepeater = e.Item.FindControl("Item1") as Repeater;
                var row = e.Item.DataItem as System.Data.DataRowView;
                columnRepeater.DataSource = row.Row.ItemArray;
                columnRepeater.DataBind();
            }
        }
