asp.net - 在 ASP.NET GridView 中实现 JQuery 数据表

Question

我想将“JQuery Datatable”与 ASP.NET GridView 一起使用。

我尝试了一些我发现的东西，但它没有用。

GridView -

<asp:GridView ID="gridViewTasks" runat="server" AutoGenerateColumns="false" CssClass="table table-striped table-bordered dt-responsive nowrap" Width="100%">
    <Columns>
        <asp:BoundField DataField="task_id" HeaderText="TaskID" Visible="false" />
        <asp:BoundField DataField="task_description" HeaderText="Task Name" />
        <asp:BoundField DataField="task_detail" HeaderText="Task Detail" Visible="false" />
        <asp:BoundField DataField="task_createdate" HeaderText="Create Date" />
        <asp:BoundField DataField="task_targetdate" HeaderText="Target Date" />
        <asp:BoundField DataField="task_isReaded" HeaderText="Task Read" Visible="false" />
        <asp:BoundField DataField="product_id" HeaderText="ProductID" Visible="false" />
        <asp:BoundField DataField="product_name" HeaderText="Product" />
        <asp:BoundField DataField="status_id" HeaderText="StatusID" Visible="false" />
        <asp:BoundField DataField="status_name" HeaderText="Status" />
        <asp:BoundField DataField="severity_id" HeaderText="SeverityID" Visible="false" />
        <asp:BoundField DataField="severity_name" HeaderText="Severity" />
        <asp:BoundField DataField="user_masterID" HeaderText="MasterID" Visible="false" />
        <asp:BoundField DataField="gorevi_veren" HeaderText="Master" />
        <asp:BoundField DataField="user_slaveID" HeaderText="SlaveID" Visible="false" />
        <asp:BoundField DataField="görevi_alan" HeaderText="Slave" />
        <asp:BoundField DataField="task_score" HeaderText="Score" />
    </Columns>
</asp:GridView>

JavaScript -

1

$(document).ready( function () {
$('#gridViewTasks').DataTable();} );

2

$(document).ready( function () {
$("#gridViewTasks").prepend( $("<thead></thead>").append( $(this).find("tr:first") ) ).DataTable() ;} );

我使用的脚本和 CSS -

<script src="jquery-1.9.1.min.js"></script>
<link href="jquery.dataTables.min.css" rel="stylesheet" />
<script src="jquery.dataTables.min.js"></script>

我还尝试了 girdView_PreRender 函数

我在使用时在 GridView 中添加引用。

protected void GridView1_PreRender(object sender, EventArgs e)
{
    // You only need the following 2 lines of code if you are not 
    // using an ObjectDataSource of SqlDataSource
    gridViewTasks.DataSource = Sample.GetData();
    gridViewTasks.DataBind();

    if (gridViewTasks.Rows.Count > 0)
    {
        //This replaces <td> with <th> and adds the scope attribute
        gridViewTasks.UseAccessibleHeader = true;
        //This will add the <thead> and <tbody> elements
        gridViewTasks.HeaderRow.TableSection = TableRowSection.TableHeader;

        //This adds the <tfoot> element. 
        //Remove if you don't have a footer row
        gridViewTasks.FooterRow.TableSection = TableRowSection.TableFooter;

    }
}

代码隐藏 - 我正在使用 Linq to SQL

var sorgu = from gorev in db.Tasks
join ga in db.Users on gorev.user_slaveID equals ga.user_id
join gv in db.Users on gorev.user_masterID equals gv.user_id
join product in db.Products on gorev.product_id equals product.product_id
join severity in db.Severities on gorev.severity_id equals severity.severity_id
join status in db.Status on gorev.status_id equals status.status_id
select new
{
    gorev.task_id,
    gorev.task_description,
    gorev.task_detail,
    gorev.task_createdate,
    gorev.task_targetdate,
    gorev.task_isReaded,
    product.product_id,
    product.product_name,
    status.status_id,
    status.status_name,
    severity.severity_id,
    severity.severity_name,
    gorev.user_masterID,
    gorevi_veren = gv.user_username,
    gorev.user_slaveID,
    görevi_alan = ga.user_username,
    gorev.task_score                       
};

gridViewTasks.DataSource = sorgu;
gridViewTasks.DataBind();

那么，如何在 ASP.NET GridView 中实现 Jquery DataTable。

Answer 1

这几行就是让它工作所需的全部内容。您不需要 prerender 事件。只需绑定(bind) Page_Load在 IsPostBack查看。我确实添加了 RowDataBound事件到GridView添加 <thead>和 <tbody>部分以编程方式而不是使用 jQuery。

<script type="text/javascript" src="https://cdn.datatables.net/1.10.9/js/jquery.dataTables.min.js"></script>
<link type="text/css" rel="stylesheet" href="https://cdn.datatables.net/1.10.16/css/jquery.dataTables.min.css" />

<asp:GridView ID="GridView1" runat="server" OnRowDataBound="GridView1_RowDataBound"></asp:GridView>

<script type="text/javascript">
    $(document).ready(function () {
        $('#<%= GridView1.ClientID %>').DataTable();
    });
</script>

背后的代码

protected void Page_Load(object sender, EventArgs e)
{
    //check for a postback
    if (!Page.IsPostBack)
    {
        //bind the gridview data
        GridView1.DataSource = source;
        GridView1.DataBind();
    }
}


protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    //check if the row is the header row
    if (e.Row.RowType == DataControlRowType.Header)
    {
        //add the thead and tbody section programatically
        e.Row.TableSection = TableRowSection.TableHeader;
    }
}

更新

如果您在 UpdatePanel 中使用 DataTable，请使用以下 javascript 来确保在 Async PostBack 之后正确绑定(bind)。

<script type="text/javascript">

    var prm = Sys.WebForms.PageRequestManager.getInstance();

    prm.add_endRequest(function () {
        createDataTable();
    });

    createDataTable();

    function createDataTable() {
        $('#<%= GridView1.ClientID %>').DataTable();
    }
</script>
