Examples

This example demonstrates how to use the GetSelectedKeysOnPage and GetVisibleRowsOnPage methods to prevent a user from deleting all rows on a single grid page (if editing logic requires it). To do this, you can compare the array length of keys obtained through GetSelectedKeysOnPage client method (returns keys only on a visible page) and the number of rows on a page obtained through GetVisibleRowsOnPage client method.

<script>
    function DeleteSelectedRows(s, e) {
        var keys = GridView.GetSelectedKeysOnPage();
        var rowsCount = GridView.GetVisibleRowsOnPage();
        if (keys.length == rowsCount) {
            alert('You cannot delete all rows on a page!');
            GridView.UnselectRowsByKey(keys);
        } else {
            if (confirm('Are you sure you want to delete rows with keys: [' + keys.toString() + ']')) {
                alert('Data editing is not allowed in this demo!');
                keys.forEach(function (key, index) {
                    GridView.DeleteRowByKey(key);
                });
            }
        }
    };
</script>
