Add row to Kendo grid dynamically

[abdul]

Hi,

I want to load a kendo grid, after load the grid should add a new row at the bottom of the grid.

 

When the Kendo grid loads then, it is creating the new row, but after that it will load the records from the database and then refresh the screen and the new row is removing.

Hello Abdul,

The easiest approach is the following:

• Set the AutoBind(false) option, which will prevent the initial data binding of the Grid when it is loaded.
• Within the $(document).ready() function, get a reference to the Grid and call the read() method of its DataSource to request the data.
• When the Read request finishes, call the AddNewRow() function. This way, the new row will be added when the Grid's data is completely loaded.

@(Html.Kendo().Grid<ProductViewModel>()
    .Name("Grid")
    .AutoBind(false)
    ...
)

<script>
function AddNewRow() {
    var newRow = { TlpModifierNew: 0 };
    var gridName = nmdModelGridTabNames[activeNmdModel3TabId - 1];
    var grid = $("#" + gridName).data("kendoGrid");
    grid.dataSource.add(newRow);
    var theCell = $('#' + gridName + " " +'tbody'+ " " +'tr:last-child td:eq(1)');
    $("#" + gridName).data('kendoGrid').editCell(theCell);     
}

$(document).ready(function(){
    var gridName = nmdModelGridTabNames[activeNmdModel3TabId - 1];
    var grid = $("#" + gridName).data("kendoGrid");
    grid.dataSource.read().then(function(){
        AddNewRow();
    });
});
</script>

Let me know if this example works for you.

Hi Mihaela,

Thanks for your response. while loading the grid i am able to add an empty row at the last in the grid.

Only problem i am facing is when i am saving few records in the grid, so after saving i am calling the below method, which will

fetch the latest records from the database and refresh the grid

After saving the grid can we call AddNewRow();  method.

Hi Mihaela,

I just did few things and also try to fix the above issue, like after saving also I am able to create a new empty row.

Accepting your answer.
