Child grid:

var selectedIds = {};

var ctlGrid = $("#KendoWebDataGrid3");
ctlGrid.kendoGrid({
    dataSource: {
        data:data1,
        schema: {
            model: {
                id: 'id',
                fields: {
                    select: {
                        type: "string",
                        editable: false
                    },

                    Qty: {
                        editable: true,
                        type: "number",
                        validation: { min: 1, required: true }
                    },
                    Unit: {
                         editable: false,

            dataSource.sync();



            });

        closeWindow();

    }

Parent Grid:

 var data1=[];
    $("#grid11").kendoGrid({
            dataSource: {
                data:data1,

            schema: {
                    model: { id: "id" ,
                        fields: {

                                    Qty: { validation: { required: true } },
                                    Unit: { validation: { required: true } },
                                    StyleNumber: { validation: { required: true } },
                                    Description: { validation: { required: true } }
                                }
                          }
                     },
            pageSize: 5
        },
        pageable: true,
        height: 260,
        sortable: true,
        toolbar: [{name:"create",text:"Add"}],
        editable: "inline",
        columns: [

              {field: "Qty"},
              {field: "Unit"},
              {field: "StyleNumber"},
              {field: "Description"},
              { command: ["edit", "destroy"], title: " ", width: "172px" }]

    });
    $('#grid11').data().kendoGrid.bind("change", function(e) {
      $('#grid11').data().kendoGrid.refresh();
    });
    $('#grid11').data().kendoGrid.bind('edit',function(e){

      if(e.model.isNew()){
           e.container.find('.k-grid-update').click(function(){
              $('#grid11').data().kendoGrid.refresh();

           }),
           e.container.find('.k-grid-cancel').click(function(){
               $('#grid11').data().kendoGrid.refresh();

           })

        }

 })

Adding data into parent grid work nicely,no issue,but when i select the parent grid add new row to edit then trigger the cancel button row was deleted.

I am not able to figure out the problem.please help me.

回答1:

I found the error, hope can help you.

If you did not config the dataSource: schema: model's "id" field, when click edit in another row before update or click cancel, it will delete the row.

var dataSource = new kendo.data.DataSource({
        ...
        schema: {
            model: {
                id:"id", // Look here, if you did not config it, issue will happen
                fields: {...
                       ...}
            }
        }   

       ...
})

I have the same issue, and I config cancel like :

...
cancel: function(e) {
           this.refresh();
      },
...

I don't think it's the best way, but it's working.

Hope another people can give us a better way.

回答3:

after saving I call $('#grid').data('kendoGrid').dataSource.read();

that cancels the edit row and reads any changes.

回答4:

Still doesn't seem to be fixed. I'm addressing it with 'preventDefault()'. This may require explicit closing of window as a consequence.

    cancel: function (e) {
        // Not sure why this is needed but otherwise removes row...
        e.preventDefault();
        e.container.data("kendoWindow").close();
    },

回答5:

schema: {
    model: { id: "StyleNumber" // "Any ID Field from the Fields list" ,
        fields: {

            Qty: { validation: { required: true } },
            Unit: { validation: { required: true } },
            StyleNumber: { validation: { required: true } },
            Description: { validation: { required: true } }
        }
    }
}

This will solve your problem.
