    <p>I got this working between shifting between 2 aspx pages in C#, but now that I change it into a popup it does not work anymore. It is an xml file which I am trying to show in the codemirror editor. It seems like that javascript is running before the pop is actully made, and there it is taking an empty textarea and rendering the codemirror on. I am not sure though, so hopefully someone is having the solution for me.</p> <p>My view is like this:</p> <pre><code> &lt;script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"&gt;&lt;/script&gt; &lt;script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js" type="text/javascript"&gt;&lt;/script&gt; &lt;link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css"/&gt; &lt;link rel="stylesheet" href="&lt;%= Html.IncludeFile("Scripts", "Codemirror/codemirror.css") %&gt;" /&gt; &lt;script type="text/javascript" src="&lt;%= Html.IncludeFile("Scripts", "Codemirror/codemirror.js")%&gt;"&gt;&lt;/script&gt; &lt;script type="text/javascript" src="&lt;%= Html.IncludeFile("Scripts", "Codemirror/xml.js")%&gt;"&gt;&lt;/script&gt; &lt;script type="text/javascript"&gt; function init() { $(document).ready( function () { $("#result").dialog({ autoOpen: false, title: 'Edit the table', width: 500, open: GetXml(), height: 'auto', modal: true }); }); openPopup(); } function openPopup() { $("#result").dialog("open"); } function GetXml() { //var selec = $("Selected").val($("FileName").val()); var Selected = document.getElementById("FileName").value; $.ajax({ type: "POST", url: "GetXmlFile", data: { Selected: $('#FileName').val() } }) .done(function (msg) { // alert("Data Saved: " + msg); $('#File').html(msg); }); } function SaveChanges() { alert('Get the values and post them back to the server to be saved!'); $("#result").dialog("close"); } &lt;/script&gt; &lt;style type="text/css"&gt; .CodeMirror { border:1px solid #334; width:auto; } &lt;/style&gt; &lt;/head&gt; &lt;body&gt; &lt;div id="result" style="display:none"&gt; &lt;% using (Html.BeginForm("Index","EditFile")) %&gt; &lt;% { %&gt; &lt;%= Html.TextAreaFor(m =&gt; m.File) %&gt; &lt;%= Html.ValidationMessageFor(m =&gt; m.File)%&gt; &lt;input type="submit" value="Save" /&gt; &lt;% } %&gt; &lt;script type="text/javascript"&gt; var editor = CodeMirror.fromTextArea(document.getElementById("File"), { lineNumbers: true, matchBrackets: true, mode: "text/xml" }); &lt;/script&gt; &lt;/div&gt; &lt;table style="width:100%;"&gt; &lt;tr&gt; &lt;td style="width:15px;"&gt;&amp;nbsp;&lt;/td&gt; &lt;td&gt; &lt;% using (Html.BeginForm()) %&gt; &lt;% { %&gt; &lt;ul&gt; &lt;li&gt; &lt;%= Html.LabelFor(m =&gt; m.FileName) %&gt; &lt;%=Html.DropDownListFor(m =&gt; m.FileName,new SelectList(System.IO.Directory .EnumerateFiles(@"C:\Something", "*") .Select(System.IO.Path.GetFileNameWithoutExtension)), "Please select one")%&gt; &lt;%=Html.ValidationMessageFor(m =&gt; m.FileName)%&gt; &lt;/li&gt; &lt;/ul&gt; &lt;% } %&gt; &lt;input type="button" onclick="init()" value="open box"&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/div&gt; </code></pre> <p> </p> <p>The method called in the controller:</p> <pre><code>[HttpPost] public String GetXmlFile(String Selected) { String selectedFileName = @"C:\Something\" + Selected + ".xml"; String line = ""; String[] linesInFile = System.IO.File.ReadAllLines(selectedFileName); foreach (var lines in linesInFile) { line = String.Concat(line, lines + Environment.NewLine); } return line; } </code></pre> <p>Any ideas?</p> <p>If this can't be done, which editor would you then suggest me to use for showing xml and editoring in the file.</p>

    1. COIt isn't clear from the description what is going wrong, but if this editor is being created in hidden state, and then shown (which is often the case in popups), you have to call its `.refresh()` method to force it to update its display (it has no way of detecting that it has been shown).

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).
