Load checked checkbox in Grid Posts

March 22, 2013 at 10:09 am Load checked checkbox in Grid #17721

Member

Hi,
I have a grid with checkbox as the first column.

In my database, there is one field named “checked”, if the value is ‘1’, I want the checkbox in the grid to be checked. How can I do that?

Regards,
Soon

Hi soonkoh,

Thanks for writing.

Here is a sample:

The type of the “available” field in the datafields array should be set to “boolean”. The implementation of the generatedata is below:

function generatedata(rowscount, hasNullValues) {
    // prepare the data
    var data = new Array();
    if (rowscount == undefined) rowscount = 100;
    var firstNames =
    [
        "Andrew", "Nancy", "Shelley", "Regina", "Yoshi", "Antoni", "Mayumi", "Ian", "Peter", "Lars", "Petra", "Martin", "Sven", "Elio", "Beate", "Cheryl", "Michael", "Guylene"
    ];
    var lastNames =
    [
        "Fuller", "Davolio", "Burke", "Murphy", "Nagase", "Saavedra", "Ohno", "Devling", "Wilson", "Peterson", "Winkler", "Bein", "Petersen", "Rossi", "Vileid", "Saylor", "Bjorn", "Nodier"
    ];
    var productNames =
    [
        "Black Tea", "Green Tea", "Caffe Espresso", "Doubleshot Espresso", "Caffe Latte", "White Chocolate Mocha", "Caramel Latte", "Caffe Americano", "Cappuccino", "Espresso Truffle", "Espresso con Panna", "Peppermint Mocha Twist"
    ];
    var priceValues =
    [
         "2.25", "1.5", "3.0", "3.3", "4.5", "3.6", "3.8", "2.5", "5.0", "1.75", "3.25", "4.0"
    ];
    for (var i = 0; i < rowscount; i++) {
        var row = {};
        var productindex = Math.floor(Math.random() * productNames.length);
        var price = parseFloat(priceValues[productindex]);
        var quantity = 1 + Math.round(Math.random() * 10);
        row["id"] = i;
        if (i % 2 == 0) {
            row["available"] = '1'
        } else {
            row['available'] = '0'
        }
        row["firstname"] = firstNames[Math.floor(Math.random() * firstNames.length)];
        row["lastname"] = lastNames[Math.floor(Math.random() * lastNames.length)];
        row["name"] = row["firstname"] + " " + row["lastname"]; 
        row["productname"] = productNames[productindex];
        row["price"] = price;
        row["quantity"] = quantity;
        row["total"] = price * quantity;
        var date = new Date();
        date.setFullYear(2013, Math.floor(Math.random() * 11), Math.floor(Math.random() * 27));
        date.setHours(0, 0, 0, 0);
        row["date"] = date;
       
        data[i] = row;
    }
    return data;
}

Best Wishes,
