BatchUpdate in ChildGrid Asp.net Core

[Yoab Youssoufou]

Hello,

I have a scenario where I have a Grid with a child grid (like displayed below), all works well but I want to implement batchupdate in the childgrid. I can implement batchupdate in the main frid but not on the child, please help with an example of batchupdate in child grid. Thanks.

Hi Yoab,  

Thanks for contacting Syncfusion Support.  

We could see you are using a local data binding for the Child Data which is not recommended way for updating. So we suggest to use the UrlAdaptor with the DataManager for binding the batchUrl to the Grid. Refer to the following code example.  

@{ 

    var ChildGrid = new Syncfusion.EJ2.Grids.Grid() 

    { 

        DataSource = new Syncfusion.EJ2.DataManager() { Url = "UrlChildDataSource", BatchUrl = "batchUpdate", Adaptor = "UrlAdaptor" }, 

        QueryString = "EmployeeID", 

         . . . 

    }; 

} 

 

<div class="control-section"> 

    <ejs-grid id="HierarchyPrint" load="onLoad"> 

        <e-data-manager url="@Url.Action("UrlDatasource")" adaptor="UrlAdaptor"></e-data-manager> 

              . . . 

                  . . . 

    </ejs-grid> 

</div> 

In case, you would like to use only the local data binding for the child Grid with the batchUrl, you can use the RemoteSaveAdaptor. Refer to the following Help Document and Code example.  

https://ej2.syncfusion.com/aspnetcore/documentation/grid/data-binding/#remote-save-adaptor 

@{ 

    var ChildGrid = new Syncfusion.EJ2.Grids.Grid() 

    { 

        DataSource = new Syncfusion.EJ2.DataManager() { json = "@ViewBag.dataSource", BatchUrl = "batchUpdate", Adaptor = "RemoteSaveAdaptor" }, 

        QueryString = "EmployeeID", 

    }; 

} 

 

<div class="control-section"> 

    <ejs-grid id="HierarchyPrint" load="onLoad"> 

        <e-data-manager url="@Url.Action("UrlDatasource")" adaptor="UrlAdaptor"></e-data-manager> 

             . . . 

                 . . . 

    </ejs-grid> 

</div>

Hi Yoab,  

Thanks for your update.  

The reported issue has been caused due to the routing problem. Refer to the following code example with the Url Helper from the Razor syntax. 

 

@{ 

    var ChildGrid = new Syncfusion.EJ2.Grids.Grid() 

    { 

        DataSource = new Syncfusion.EJ2.DataManager() { 

            Url = Url.Action("UrlChildDataSource"), 

            BatchUrl = Url.Action("batchUpdate"), 

            Adaptor = "UrlAdaptor" 

        }, 

        QueryString = "EmployeeID",  

              . ..  

                    . .. 

    }; 

} 

 

<div class="control-section"> 

    <ejs-grid id="HierarchyPrint" childGrid="ChildGrid"> 

        <e-data-manager url="@Url.Action("UrlDatasource")" adaptor="UrlAdaptor"></e-data-manager> 

             . . .  

               . . .   

    </ejs-grid> 

</div> 

We have also prepared a sample that can be downloaded from the following location.

Hello one more thing. One of my columns in the childgrid is a boolean I want to represent with a check box. My code is below:

 @{
        var ChildGrid = new Syncfusion.EJ2.Grids.Grid()
        {
            DataSource = new Syncfusion.EJ2.DataManager()
            {
                Url = Url.Action("UrlChildDataSource"),
                BatchUrl = Url.Action("batchUpdate"),
                Adaptor = "UrlAdaptor"
            },
            QueryString = "ProcessId",
            Aggregates = new List<Syncfusion.EJ2.Grids.GridAggregate> {
            new Syncfusion.EJ2.Grids.GridAggregate() {Columns = col} },
            EditSettings = new Syncfusion.EJ2.Grids.GridEditSettings()
            {
                AllowAdding = true,
                AllowEditing = true,
                AllowDeleting = true,
                Mode = Syncfusion.EJ2.Grids.EditMode.Batch
            },
                Toolbar = new List<string>() { "Add", "Edit", "Delete", "Update", "Delete" },
            Columns = new List<Syncfusion.EJ2.Grids.GridColumn> {
                new Syncfusion.EJ2.Grids.GridColumn(){ Field="Id", Width="80", AllowEditing=false, Visible=false },
                new Syncfusion.EJ2.Grids.GridColumn(){ Field="ProcessId", Width="80", AllowEditing=false, Visible=false },
                new Syncfusion.EJ2.Grids.GridColumn(){ Field="DrugsId", HeaderText="Drug Description", Width="80", AllowEditing=false, Visible=false },
                new Syncfusion.EJ2.Grids.GridColumn(){ Field="Notes", HeaderText="Posology", Width="200", TextAlign=Syncfusion.EJ2.Grids.TextAlign.Left , AllowEditing=false},
                new Syncfusion.EJ2.Grids.GridColumn(){ Field="Quantity", HeaderText="Quantity", Width="80", AllowEditing=false },
                new Syncfusion.EJ2.Grids.GridColumn(){ Field="Cost", HeaderText="Cost", Width="80", Format="N2", AllowEditing=false },
                new Syncfusion.EJ2.Grids.GridColumn(){ Field="DispenseStatus", HeaderText="Dispensed?", DisplayAsCheckBox=true,  Width="60" }
    }
        };
    }

I also tried adding to the colum Type="Boolean", EditType="BooleanEdit" all to no avail, checkboxes are properly displayed but in editmode (adding or editing) the grid displays true or false I have recorded a short video as well as a screenshot attached. I wish to have a checkbox for editing. Thanks

Please disregard problem solved, it was a simple syntax error "booleanedit" is supposed to be in all small letters, it can get confusing mixing pascal, camel and no cases

 new Syncfusion.EJ2.Grids.GridColumn(){ Field="DispenseStatus", HeaderText="Dispense?",EditType="booleanedit", DisplayAsCheckBox=true,  Width="60" }
