in slickgrid how I can delete a row from a javascript function - row

Question

how I can delete a row from a javascript function from a button
for example

Answer 1

If you're using a DataView, use the following:
DataView.deleteItem(RowID);//RowID is the actual ID of the row and not the row number
Grid.invalidate();
Grid.render();
If you only know the row number, you can get theRowID using:
var item = DataView.getItem(RowNum);//RowNum is the number of the row
var RowID = item.id

Answer 2

Suppose you are using jQuery
var grid;
$(function () {
// init options, load data
...
var columns = [];
columns[0] = {
id: 'id',
name: '#',
field: 'id', // suppose you have an id column in your data model
formatter: function (r, c, id, def, datactx) {
return 'X'; }
}
// init other columns
...
grid = new Slick.Grid($('#gridDiv'), data, columns, options);
}
function RemoveClick(databaseId, gridRow) {
// remove from serverside using databaseId
...
// if removed from serverside, remove from grid using
grid.removeRow(gridRow);
}

Answer 3

This is how i do it (not using any data provider though):
//assume that "grid" is your SlickGrid object and "row" is the row to be removed
var data = grid.getData();
data.splice(row, 1);
grid.setData(data);
grid.render();
I use this in a live project and it runs well. Of course, if you want to remove multiple rows then a few tweaks should be made, or if you use a data provider then you'd maybe want to remove the row only from the data provider and then have SlickGrid just refresh the rows.
Hope it helps :)

Answer 4

function deleteRows() {
var selectedIndexes = grid.getSelectedRows().sort().reverse();
var result = confirm("Are you sure you want to delete " + grid.getSelectedRows().length + " row(s)?");
if (result) {
$.each(selectedIndexes, function (index, value) {
var item = dataView.getItem(value); //RowNum is the number of the row
if (item)
dataView.deleteItem(item.id); //RowID is the actual ID of the row and not the row number
});
grid.invalidate();
grid.render();
}
}

Answer 5

var rowsToDelete = grid.getSelectedRows().sort().reverse();
for (var i = 0; i < rowsToDelete.length; i++) {
data.splice(rowsToDelete[i], 1);
}
grid.invalidate();
grid.setSelectedRows([]);

Answer 6

yes of course, I use it this way
var selrow = grid.getSelectedRows ();
data.splice(selrow, 1);
grid.invalidateAllRows();
grid.render ();

Answer 7

hi
i'm used this script for delete row of SlickGrid
function deletefila(numrow)
{
alert("delete row"+numrow);
data.splice(numrow,1);
grid.removeAllRows();
grid.render();
//grid.removeRow(5);
//grid.updateRowCount();
//and then invalidate and re-render the grid by calling grid.removeAllRows() followed by grid.render().
}
