    <p>I have previously posted a question about this code to <a href="https://stackoverflow.com/q/15779973/2236074">generate a kendo grid dynamically</a>.</p> <p>The current problem I have now, even when I hardcode the number of columns like so:</p> <pre><code>var numberOfRows = 2; var numberOfColumns = 12; var columnsPerRow = numberOfColumns/numberOfRows; </code></pre> <p>Is that I get the error :</p> <p><img src="https://i.stack.imgur.com/UStB2.png" alt="enter image description here"></p> <pre><code>First of all, what does this mean? </code></pre> <p>The columnsPerRow is used like so:</p> <pre><code>var columnDefs = []; counter = 0; var arrayData = []; for( var x = 0; x &lt; result.length-1; x=x+Math.floor(columnsPerRow)+1 ) { var tempArr = new Array(); for( var y = 0; y &lt; columnsPerRow; y++ ) { var num = x + y; tempArr.push(result[num]); } arrayData.push(tempArr); } var dataTitles = []; for( var x = 0; x &lt; titleArray.length; x++ ) { var head = ""; head = titleArray[x]; head = head.replace(/ /g,""); dataTitles.push(head); } var counter = 0; var columnDefs = []; for (var i = 0; i &lt; columnsPerRow.length; i++) { if (counter == (columnsPerRow - 1)) { counter = 0; } columnDefs.push({ field: dataTitles[counter], template: result[i].value }); counter++; } </code></pre> <p>The grid is displayed as so:</p> <p><img src="https://i.stack.imgur.com/qVaPw.png" alt="enter image description here"></p> <p>and when I hide the column variables like so:</p> <pre><code>/*var numberOfRows = 2; var numberOfColumns = 12; var columnsPerRow = numberOfColumns/numberOfRows;*/ </code></pre> <p>the output looks as it's supposed to:</p> <p><img src="https://i.stack.imgur.com/wuwnK.png" alt="enter image description here"></p> <p>but then null values are used for the number of columns, thus the for loop does not loop.</p> <p>Except that the grid does not display the data.</p> <p>I have placed all my javascript and html in this <a href="http://jsfiddle.net/5sWue/2/" rel="nofollow noreferrer">jsfiddle</a>. Although it's not working in the fiddle. There might be some unused code. I'm busy removing it as I go along.</p> <p>I've got these files attached:</p> <pre><code>&lt;link href='assets/css/kendo.custom.css' rel='stylesheet' type='text/css' /&gt; &lt;link href='assets/css/kendo.common.min.css' rel='stylesheet'/&gt; &lt;link href='assets/css/kendo.default.min.css' rel='stylesheet' type='text/css' /&gt; &lt;script src='assets/js/jquery.min.js'&gt;&lt;/script&gt; &lt;script src='assets/js/kendo.all.min.js'&gt;&lt;/script&gt; </code></pre> <p>and how can I fix this issue that data will be displayed in the grid?</p> <p>Any help will be appreciated, thanks...</p>

    1. COIn the fiddle that you have provided, there is no `tableTitle` array provided which causes an error... I have updated the fiddle with some `tableTitle` test array an it seems to work (except for styling, but I guess that it is because I have not the `kendo.custom.css` stylesheet) : http://jsfiddle.net/5sWue/4/.

    2. COThanks @SamuelCaillerie , although I found that that was not the only problem. Because of all the changes I made trying to simplify the coding, I forgot to make some slight changes as I posted below.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
