    Below is my code, How do I initialize columns in a grid through a for loop?

    my

    var documentName=["HSBC inc.","City Bank","Countrywide Loans","Bank of America"]; 

    can be change and can have diffident number of values to the
    I want to initialize the columns according to the size of

    var documentName

    If above is not possible through a for loop how do I initialize columns dynamically.

        var source2 =
    {
    localdata: data2,
    datatype: "array"
    };
    var documentName=["HSBC inc.","City Bank","Countrywide Loans","Bank of America"];
    if (tabsdiv != null) {
    tabsdiv.jqxGrid({source: source2, theme: theme, width: 700, height: 200,
    columns: [
    for (var i = 0; i < documentName.length; i++) {
    { text: documentName[i], datafield: 'doc'+i, width: 150 },
    }
    ]
    });
    }

    Hello kkasunperera,

    Here is an example that shows how to add columns with a for loop:

    if (parentsLength > 3) {
    url = 'demos/sampledata/beverages.txt';
    }
    // prepare the data
    var source =

    url: url
    };
    var dataAdapter = new $.jqx.dataAdapter(source);
    var documentName = ["name", "type", "calories", "totalfat", "protein"];
    var columnsData = [];
    for (var i = 0; i < documentName.length; i++) {
