[Solved] Grid in hidden div renders lightgrey on mobile

[Erik]

Hi - I'm using the Kendo Grid and it is behaving strangely on mobile devices when being included in
an initially-hidden div.  I'm using Bootstrap and the latest version of Kendo UI.

 

The basic layout is this -- I have a button toward the bottom of a Bootstrap panel, and a div underneath that (still
inside the panel), which gets initialized to a kendo grid and has an initial style of "display:none;".
The button toggles the display of the grid.  This works perfectly on desktop browsers.

 

On mobile devices a light grey renderding of the space for the grid shows up (see the "HiddenDivs" image).  When I
click the "Show / Hide" button, the grid shows up nicely (see the "showing data" image).

 

What can I do to prevent the light grey showing when the grid is hidden?

 

Here is the HTML code:

<div id="paymentHistoryButtons" style="padding-bottom: 30px;">
    <button class="btn btn-xs btn-info pull-right" onclick="viewPaymentHistory();">Show / Hide History</button>
</div>
<div id="PaymentHistoryGrid" style="display: none;"></div>

Here is the javascript that sets up the grid -- the "getPaymentHistory" function is called in document.ready.

function getPaymentHistory() {
        $('#PaymentHistoryGrid').html('');

        var consumerId = @NwpSession.SelectedAccount.ConsumerId;
        var merchantId = @NwpSession.SelectedAccount.PropertyMerchantId;

        var window = $("#window").kendoWindow({
            title: "Cancel Payment",
            visible: false, //the window will not appear before its .open method is called
            width: "400px",
            height: "200px",
        }).data("kendoWindow");
        var windowTemplate = kendo.template($("#windowTemplate").html());

        var rot = OneResidentUtilities.getResourceOwnerToken();

        $("#PaymentHistoryGrid").kendoGrid({
            columns: [
            { title: 'Date', field: 'DueDate', type: 'date', format: '{0:MM/dd/yyyy}' },
            { title: 'Tracking Number', field: 'TrackingNumber', width: 125},
                { title: 'Amount', field: 'Amount', format: '{0:C}' },
                { title: 'Status', field: 'PaymentStatusString' },
                {
                    command: {
                        name: 'cancelButton',
                        text: 'Cancel',
                        click: function(e) {
                            var tr = $(e.target).closest("tr"); //get the row for deletion
                            var data = this.dataItem(tr); //get the row data so it can be referred later
                            window.content(windowTemplate(data)); //send the row data object to the template and render it
                            window.open().center();

                            $("#yesButton").click(function() {
                                cancelPayment(data);
                                window.close();
                            });
                            $("#noButton").click(function() {
                                window.close();
                            });
                        },
                        className: 'btn btn-primary btn-xs'

Hello Erik,

It seems that the Grid is missing a height and position style for its parent. Please check the documentation:
