jQuery Grid Selection

The Grid component supports selection out of the box.
You can customize the selection behavior further, by setting properties in the "selection" section.
This is demonstrated below:

 

$("#grid").shieldGrid({
    dataSource: {
        data: [
            { ID: 1, name: "name1" },
            { ID: 2, name: "name2" }
        ]
    },
    selection: 
    {
        type: "cell",
        multiple: false,
        toggle: true
    }
    columns: [
        { field: "ID", title: "Unique Number", format: "{0:c}" },
        { field: "name", title : "Name", width: "300px" }
    ]
});

The type property specifies whether selection will be row-based or cell-based.
multiple specifies whether multiple elements can be selected.
toggle determines whether selecting an element will toggle or turn off the previous selection.
