How to remove all rows from a Kendo grid

Question

I am using Kendo grid.

I want to remove all rows from Kendo grid using JavaScript.

I removed them using a for loop but I want to find the best way to remove all rows.

Answer 1

try following the code.

var grid = $("#Grid").data('kendoGrid');             grid.dataSource.data([]);  grid.setDataSource([]);

Update: Fixed sorting issue... Thanks @Windle

Answer 2

That doesn't really move the underlying data of the grid, it just clears the rows being displayed. If you sort the "empty" grid, all the rows reappear form the underlying data.

If instead of removing your data as shown like this:

dataSource.data([]); 

and instead replace it with a new array of data, say called result.Data.. like this:

dataSource.data(result.Data) 

you will see the data swap, but if sort or page, again the original data is shown.

Anyone know how to actually change the data and have the new data replace the source data of the grid?

UPDATE: The answer is to ALSO use the setDataSource method:

var grid = $("#grid").data("kendoGrid"); var dataSource = grid.dataSource; dataSource.data([]);//clear out old data dataSource.data(result.Data);//add new data grid.setDataSource(result.Data);//set the new data as the grids new datasource dataSource.sync();//refresh grid
