Description

How can I consolidate the save operations of all the Telerik UI for ASP.NET Core Grids through an external Save button?

Solution

To achieve the desired scenario:

1. Create an external Save Button and subscribe to its Click event.
2. Within the Click handler, loop through all utilized Grids by accessing them through the .k-grid class and save the changes by using the saveChanges() method.

    @(Html.Kendo().Button()
      .Name("saveBtn")
      .Content("Save changes")
      .Events(e=>e.Click("onClickHandler"))
    )

    <h1>Grid #1</h1>
    @(Html.Kendo().Grid<Kendo.Mvc.Examples.Models.ProductViewModel>()
        .Name("grid1")
        .Columns(columns => {
            columns.Bound(p => p.ProductName);
            columns.Bound(p => p.UnitPrice).Width(140);
            columns.Command(command => command.Destroy()).Width(150);
        })
        .ToolBar(toolbar => {
            toolbar.Create();
        })
        .Scrollable()
        .Height(200)
        .Editable(editable => editable.Mode(GridEditMode.InCell))
        .DataSource(dataSource => dataSource
            .Ajax()
            .Batch(true)
            .PageSize(20)
            .ServerOperation(false)
            .Model(model => model.Id(p => p.ProductID))
            .Create("Editing_Create", "Grid")
            .Read("Editing_Read", "Grid")
            .Update("Editing_Update", "Grid")
            .Destroy("Editing_Destroy", "Grid")
        )
    )

    <h1>Grid #2</h1>
    @(Html.Kendo().Grid<Kendo.Mvc.Examples.Models.ProductViewModel>()
        .Name("grid2")
        .Columns(columns => {
            columns.Bound(p => p.ProductName);
            columns.Bound(p => p.UnitPrice).Width(140);
            columns.Command(command => command.Destroy()).Width(150);
        })
        .ToolBar(toolbar => {
            toolbar.Create();
        })
        .Height(200)
        .Scrollable()
        .Editable(editable => editable.Mode(GridEditMode.InCell))
        .DataSource(dataSource => dataSource
            .Ajax()
            .Batch(true)
            .PageSize(20)
            .ServerOperation(false)
            .Model(model => model.Id(p => p.ProductID))
            .Create("Editing_Create", "Grid")
            .Read("Editing_Read", "Grid")
            .Update("Editing_Update", "Grid")
            .Destroy("Editing_Destroy", "Grid")
        )
    )

    <script type="text/javascript">
            function onClickHandler(e){
                $(".k-grid").each(function (index, value) {
                     var grid = $(this).data("kendoGrid"); // Get the reference of the current Grid widget instance.
                     grid.saveChanges(); // Save the changes for the current Grid widget instance.
                });
            }
    </script>
