columns

Specifies the XPath expression for the table columns (cells).

The default columns XPath is "*" - selecting all child nodes under the row node. Use setColumns(xpath) or setColumns([xp1, xp2 ...]) to specify different location or subset of the cell nodes. It is possible to use expressions for the attributes ("@name"), elements ("name") or any other valid xpath. The xpath is evaluated relative to the row node.

Syntax

var value = obj.getColumns(); 
obj.setColumns(value);        

Examples

The following example displays column data using child elements, row attribute (@id) and child node attribute (price/@ccy).

<xml id="data">
    <orders>
        <order id="101">
            <product>RedWidget</product>
            <price ccy="USD">456.00</price>
            <qty>10</qty>
        </order>
        <order id="102">
            <product>BlueWidget</product>
            <price ccy="GBP">123.00</price>
            <qty>1</qty>
        </order>
    </orders>
</xml>

<script>

    var table = new AW.XML.Table;
    table.setColumns(["@id", "product", "price", "price/@ccy", "qty"]);
    table.setXML(document.getElementById("data"));

    var obj = new AW.UI.Grid;
    obj.setCellModel(table);
    obj.setColumnCount(5);
    obj.setRowCount(2);
    document.write(obj);

</script>
