Question

我有一个要求，比如我需要找到父网格行复选框，如果检查父网格行复选框，那么我需要将所有子网格复选框设置为为该父网格行复选框为真，我已经这样做了....

 <script type="text/javascript">
    $(document).ready(function () {
        $('#btnMove').click(function () {                                        
        var parentgrid = $('#GridParent').data('kendoGrid');  
        var childGrid = $('#GridParent').closest(".k-grid").data("kendoGrid");               
        var Count = $('#Gridparent').data("kendoGrid").dataSource.total();
        alert(Count);
      for (i = 0; i < Count; i++) 
     {
          var isChecked = parentgrid.tbody.find('tr:eq(' + i + ')').find('td').find('.chkbxq').is(':checked');
          alert(isChecked); // here i need to get the property of parent grid row checkbox and I am not getting this alert....                  
          if (isChecked == true)
          {
             var allchildgridchkboxes = childGrid.tbody.find('td').find('chkbx');
             alert(allchildgridchkboxes); // i am not getting this alert     
             // here i need to set the all checkboxes checked property to true
          }

     }     
   });
 });
</script>

这是我的观点，我在网格中定义复选框...

任何人都可以帮忙...如何查找父网格行复选框以及如何获取子网格的所有复选框....

请看图像......我需要获取两个网格的复选框参考

在我的代码中，checkbox中的header不在td，但这有助于您找到相应的child grid checkbox，

<script type="text/javascript">
    $(document).ready(function () {
          $('#grid12').on("click", ".chkbxq", function (e) {
        var $this = $(this);
        var selected = $this.is(':checked');
        var id = $this.attr('id');
        var value = id.replace('checkbox_', '');
        var rowIndex = $this.parent().index();
        var cellIndex = $this.parent().parent().index();
        var grid = $("#grid12").data("kendoGrid");
        var datatItem = grid.dataItem(grid.tbody.find('tr:eq(' + cellIndex + ')'));

         var childgridid = $('.k-detail-row').find('td.k-detail-cell').find('div.k-grid').attr('id');
          var valurchildgrid = childgridid.replace('grid_', '');
          var childrowscount = $('div[id*="grid_' + valurchildgrid + '"]').data("kendoGrid").dataSource.total();

        var check = $('.k-detail-row').find('td.k-detail-cell').find('div.k-grid').find('table').find('tbody').find('input[id*="checkboxChild_' + value + '"]').each(function () {
            if (selected == true) {
                $(this).attr('checked', 'checked');
            }
            else {
                $(this).attr('checked', false);
            }
        });        



    });
});
</script>

                    .Name(" grid_#=CostPage#")

            {

           .DataSource(dataSource => dataSource
               .Ajax()
               .PageSize(5)
                       .Read(read => read.Action("ReadGrid", "Test"))
           )
           .ToClientTemplate()

@using (Html.BeginForm("GridListView", "Test", FormMethod.Post))
{ 

@*<input id="Submit1" type="button" value="SubmitValue" />*@
    <input id="btnsubmit" type="button" value="SubmitValue" />
    @(Html.Kendo().Grid<TwoModelInSinglePageModel.SampleModel>()
    .Name("grid12")
    .Columns(columns =>
    {
        columns.Bound(p => p.studentclass).HeaderTemplate("<input id='selectall' class='chkbxq' type='checkbox'  />").ClientTemplate("<input id='checkbox_#=inx#' class='chkbxq' type='checkbox' />");
        columns.Bound(p => p.SampleDescription);
        columns.Bound(p => p.SampleCode);
        columns.Bound(p => p.SampleItems);
    })
        .ClientDetailTemplateId("client-template")
        .AutoBind(true) // here I am disabling automatic binding at page load
       .DataSource(dataSource => dataSource
        .Ajax()
            .Read(read => read.Action("Read", "Test"))
     )
  )

在Child Grid中，在每个孩子unique-key中传递checkbox。 INX是我们的unique-key。通过Unique-key这样id='checkboxChild_#=inx#'。
