    <p>I have a form where the user can enter information in several Textboxes.</p> <p>The textboxes are created like so -</p> <pre><code>GroupSection courseNumber = new GroupSection(getH4Title("")); courseNumber.addStyleName(LUUIConstants.STYLE_SECTION); courseNumber.addStyleName(LUUIConstants.STYLE_SECTION_DIVIDER); // KSTextBox extends TextBox incidentally // I've added some custom functionality in my version of this class KSTextBox subjectCodeTextBox = new KSTextBox(); KSTextBox courseNumberTextBox = new KSTextBox(); . . . addField(courseNumber, COURSE + "/" + SUBJECT_AREA, generateMessageInfo(LUUIConstants.SUBJECT_CODE_LABEL_KEY), subjectCodeTextBox); addField(courseNumber, COURSE + "/" + COURSE_NUMBER_SUFFIX, generateMessageInfo(LUUIConstants.COURSE_NUMBER_LABEL_KEY), courseNumberTextBox); . . . courseNumber.addSection(generateCrossListed_Ver_Joint_Section()); return courseNumber; </code></pre> <p>Here's what it looks like rendered: <img src="https://i1328.photobucket.com/albums/w524/amberkoff/snapCourse_zps3c2887fc.png" alt="2 Text boxes"></p> <p>This same page on which these Text boxes are located is re-used in my application in for different scenarios; however, for one particular scenario, I need to make them read-only.</p> <p>The way that I have identified this scenario is checking the title of the page. If there is the keyword "Modify" located on the page - I do not want the user to be able to change the values that are being auto-filled in those text boxes.</p> <p>I've almost achieved this by implementing this -</p> <pre><code>subjectCodeTextBox.addBlurHandler(new BlurHandler() { @Override public void onBlur(BlurEvent blurEvent) { NodeList&lt;Element&gt; elements = Document.get().getElementsByTagName("div"); for (int i = 0; i &lt; elements.getLength(); i++) { Element elem = elements.getItem(i); String innerHTML = elem.getInnerHTML(); if (innerHTML.contains("Modify")) { subjectCodeTextBox.setReadOnly(true); courseNumberTextBox.setReadOnly(true); } break; } } }); courseNumberTextBox.addBlurHandler(new BlurHandler() { @Override public void onBlur(BlurEvent blurEvent) { NodeList&lt;Element&gt; elements = Document.get().getElementsByTagName("div"); for (int i = 0; i &lt; elements.getLength(); i++) { Element elem = elements.getItem(i); String innerHTML = elem.getInnerHTML(); if (innerHTML.contains("Modify")) { subjectCodeTextBox.setReadOnly(true); courseNumberTextBox.setReadOnly(true); } break; } } }); </code></pre> <p>The above code works, but it will only fire after the user has clicked in and then out of one of those 2 text boxes. But by then, they could have changed the values and don't want that --- I'd prefer those boxes to be disabled when the page gets first rendered.</p> <p><strong>How do I setup those textboxes to already be READONLY when the page first renders for the user?</strong></p> <p>I figure it has something to do with the ONLOAD event, but how do I set it up properly?</p>

    1. COI must be missing something - why are you putting that in the blur handler instead of calling it right away, or calling it as soon as the 'Modify' keyword is actually added on the page? Can't you set them readonly then?

    2. COThis is part of an Enterprise Application that utilizes MVC and Spring. The rootPanel exists elsewhere in the application. This particular class simply returns only a small segment (Section). This same page is used in several scenarios - Modify, Create, and Retire. The Modify keyword is inserted in a completely different class in another section where I don't have a reference to these text boxes. It has to happen here.

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.

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