如何将表绑定到ListView应该使用哪个控件， LinqDataSource或者应该使用ObjectDataSource什么DataSourceIDListView

我的ListView是

<asp:ListView ID="ListViewResult" runat="server" DataSourceID="" GroupItemCount="3">
                    <EmptyDataTemplate>
                        <table id="Table1" runat="server" style="background-color: #FFFFFF;border-collapse: collapse;border-color: #999999;border-style:none;border-width:1px;">
                            <tr>
                                <td>No data was returned.</td>
                            </tr>
                        </table>
                    </EmptyDataTemplate>
                    <EmptyItemTemplate>
<td id="Td1" runat="server" />
                    </EmptyItemTemplate>
                    <GroupTemplate>
                        <tr id="itemPlaceholderContainer" runat="server">
                            <td id="itemPlaceholder" runat="server"></td>
                        </tr>

我认为可能是：

ListViewResult.DataSource = ds;

利用

ListViewResult.DataSource = ds.Tables[0];

或者

ListViewResult.DataSource = ds.Tables("TableName");

请替换所有这些：

if(From = 21 && To = 24)
{
    (Males.Age == 21 || Males.Age == 22 || Males.Age == 23 || Males.Age == 24)
}

只是与

(Males.Age >= From && Males.Age <= To)

好的，我这样做了，我想在 ListView 上显示两个表的数据，这样我就不需要在一个页面上使用两个列表视图，

我所做的是，我插入了两个 ListViews 和两个 LinqDataSource 并附加了它们，然后这样做了。

 protected void Page_Load(object sender, EventArgs e)
    {

        if(!Page.IsPostBack)
        {

            ListViewGroom.Visible = false;
            ListViewBride.Visible = false;
        }
        else if(Page.IsPostBack)
        {
            if (RadioButtonGroom.Checked == true)
            {
                ListViewBride.Visible = false;
            }
            else if(RadioButtonBride.Checked == true)
            {
                ListViewGroom.Visible = false;
            }
        }
    }



    protected void ButtonSearch_Click(object sender, EventArgs e)
    {
        using (WebTechManiaDataContext Data = new WebTechManiaDataContext())
        {
            string Education = DropDownListEducation.SelectedItem.Text.ToString();
            string MaritalStatus = DropDownListMaritalStatus.SelectedItem.Text.ToString();
            int From = int.Parse(DropDownListFrom.SelectedItem.Text);
            int To = int.Parse(DropDownListTo.SelectedItem.Text);

            if (RadioButtonGroom.Checked == true | RadioButtonBride.Checked == false)
            {
                if ((From == 21) && (To == 22))
                {
