I am currently using Umbraco 7.1.8 and I have just finished my final template however I wanted to create a tag like list for the client to add in as they wish.
I have a multiple textbox with the alias workUndertaken however when I call it, it echos System.String[].
My code is pretty simple - I called it two different ways to ensure it wasn't an issue with one method.
<p>#Model.Content.GetPropertyValue("workUndertaken")</p>
<p>#Umbraco.Field("workUndertaken")</p>
Does anyone know where I am going wrong?
Sorry got the answer almost instantly. Was hard to find.
So I will post the answer with the code I am now using. Hopefully others find this useful.
#{
if (Model.Content.GetPropertyValue<string[]>("workUndertaken").Length > 0) {
<ul>
#foreach (var item in Model.Content.GetPropertyValue<string[]>("workUndertaken")) {
<li>#item</li>
}
</ul>
}
}

I have an issue with removing old elements from my lists. I tried using the methods clear() and removeAllElements() and removeAll() wherever I could but that does not seem to clear them.
To help you understand the situation a little bit better:
d1 is an ArrayList that contains all available devices in our program.
availList2 and availList3 are using the DefaultListModel.
We wanted to make it so that when the user loads the products from the proper text file, if he did that a second time the products already listed in our gui would be overwritten with the ones in the original text file. However we ended up having duplicates of the products, even though we used the clear() method in both the d1 (ArrayList) and the JList.
Any useful tips or possible causes would be appreciated. Thank you very much in advance.
if(ev.getSource() == load_availables) {
int returnVal = chooser.showOpenDialog(mainApp.this);
if(returnVal == JFileChooser.APPROVE_OPTION) {
d1.returnDevices().removeAll(d1.returnDevices());
availList2.clear();
availList3.clear();
//availList2.removeAllElements();
//availList3.removeAllElements();
File file = chooser.getSelectedFile();
read.ReadDevices(file);
for(int i = 0; i < read.Size(); i++) {
d1.add_AvailableDevices(read.get(i));
}
}
}
If the list is not cleared then I would suggest you don't have the proper reference to the DefaultListModel that is being used by the JList when you invoke the clear() method.
Start by the reading the section from the Swing tutorial on How to Use Lists.
Download the ListDemo code and play with it. Change the "Fire" button to use the clear() method on the DefaultListModel to prove to yourself that is all you need to do.
Once you see the code working then you figure out how your code is different from the ListDemo working version.
this is my template : http://pastebin.com/Gmdmqwxa
Whenever I add comment it is adding always to the first question on the list, even if I click on the others question 'Add Comment' button.However, the remove button works just fine for all the questions.
I think i know what it is working like that, so i thought i could use iterStat or something like that to iterate through questions, and then set th:action with iterStat, but its not working
<div th:each="question, iterStat : ${person.questions}" >
th:action="#{'/newComment/' + ${iterStat.current}}"
Maybe anyone has different idea how to fix this issue ?
For a TV Guide, I am trying to create a dynamic expression within an ng-repeat directive as follows:
<div ng-repeat="programme in programmes['{{channel}}-wed-jan-14']" alt="{{channel}}">
{{channel}} in my controller should evaluate to something like "eTV". The binding is working fine with the alt="{{channel}}" instance but not with the array instance. Angular simply serves up the line of code commented out. If I hardcode the "eTV" string in place of the {{channel}}, it works fine.
Am I trying to ask Angular to do what it is not designed for, or is it possibly my array handling which is dodgy?
Okay, not sure if I just asked a dumb question, but in the absence of responses, I managed to figure out a solution by writing a filter as follows:
Template:
<div ng-repeat="programme in programmes | getChannelDay:channel:dayString" alt="{{channel}}">
Controller filter:
app.filter('getChannelDay', function() {
return function(programmes, channel, dayString) {
return programmes[channel + dayString];
};
});
The issue with my initial problem
<div ng-repeat="programme in programmes['{{channel}}-wed-jan-14']" alt="{{channel}}">
is that I was trying to put {{channel}} inside the expression, but that is the format for markup.
I tried to use the following instead:
<div ng-repeat="programme in programmes['channel + daystring']" alt="{{channel}}">
but I am doing something wrong here. I am pretty sure there is a way to get this to work - if anyone knows, please comment.
I don't know what this is called, and I've messed around a lot with the headerTemplate but can't figure out how to produce this look. I need the second row of column names to 'act normally' in terms of sorting and filtering, but everything I try breaks that. I have no idea if headerTemplate is even the right way to do this? Is there a name for this kind of grouping? My research is turning up a whole lot of nothing, so I suspect I'm using the wrong keywords. What is this layout called?
Note: for security reasons I can't post a code dump (super nervous about the image too). If a specific thing is needed, please let me know and I'll try to anonymize it. But, mostly I'm just looking for suggestions to try other than playing with the headerTemplate.
This is now natively supported by the Kendo grid. Here's an example.
You won't be able to achieve multirow Group headers via Kendo grid on MVC, although there were discussion to add the feature in the current version(2014Q2) of Kendo. See below link for more reference:
Pivot Grid StackOverflow Reference
However, you can achieve the multirow header option via jquery on databound event of the grid. But it is a workaround rather than a perfect soultion.
Please see the js function for databound event to add multirow header:
function onDataBound(arg) {
var myElem = document.getElementById('trParentHeader'); //Check if Parent Header Group exist
if (myElem == null){ // if parent Header doesnot exist then add the Parent Header
$("#grid").find("th.k-header").parent().before("<tr id='trParentHeader'> <th colspan='2' class='k-header'><strong>Products + Unit Price</strong></th> <th scope='col' class='k-header'><strong>Single Units in Stock</strong></th></tr>");
}
}
For more understanding and a working example please see below Sample:
MultiRow-Column Header Sample
Please let me know if you if you have any queries.
If you go to www.lindysez.com and click on the top level navigation links, you'll notice that position presence is indicated by a slightly darker background (same as hover state). This works for each of the links EXCEPT "Tips & Techniques".
If I look under the hood, I noticed that the "current_page_item" class isn't being added to the parent of the "Tips & Techniques" menu item when you go to http://www.lindysez.com/tips
Also, curiously enough, when on the tips page, the parent of the "Blog" navigation item gets the class "current_page_parent", which is neither expected nor desired. This is harmless from a UI standpoint, but probably an indication what the underlying problem might be.
Anyone know why the "Tips & Techniques" menu item isn't getting the "current_page_item" class once selected?
Update: Directed #user2019515's comment below
Thanks for the nudge in this direction, it does seem like I could create a workaround that would fix this. Couple things however.
This treats the symptom of the problem rather than the root. I'd like to figure out how to get wp to just add the "current_page_item" class natively. Any idea what's causing this? I think it may also be related to another problem I'm having which involves "tips" not showing in the RSS feed. I posted another question about that, but haven't seen any answers...
https://stackoverflow.com/questions/15980846/custom-post-type-not-showing-up-in-wordpress-rss-feed
Even as a workaround, I'd rather try to avoid a solution that relies on hard coded "menu-item-##". My development and production servers both have different ID#'s. I know I can account for this, but I hope there's a better, scalable workaround.
The code you provided didn't work for me, not that I can find any fault in it, nor are there any errors. Seems like it should work, but just doesn't. I even tried creating a very simple version that would add a class to all the items, but this too isn't executing. Here's that code.
function add_class_to_wp_nav_menu($classes, $item)
{
$classes[] = 'classy-class';
return $classes;
}
add_filter('nav_menu_css_class', 'add_class_to_wp_nav_menu', 10, 2);
Thanks so much for your help!
The Tips page is a post archive page, it shows posts rather than a normal page that's why the blog was being highlighted. You can easily fix this issue by adding the following custom CSS to your style.css file.
.post-type-archive-tips .menu-item-23{
background:url(images/nav-hover.png) repeat-x;
}
You'll need to loop over your menu, by default the current page class is added to the blog page because in the end the custom posts.
//Change current_page_parent for custom post type
function remove_parent_classes($class)
{
// check for current page classes, return false if they exist.
return ($class == 'current_page_item' || $class == 'current_page_parent' || $class == 'current_page_ancestor' || $class == 'current-menu-item') ? FALSE : TRUE;
}
function add_class_to_wp_nav_menu($classes)
{
switch (get_post_type()) {
case 'portfolio':
// we're viewing a custom post type, so remove the 'current_page_xxx and current-menu-item' from all menu items.
$classes = array_filter($classes, "remove_parent_classes");
// add the current page class to a specific menu item (replace ###).
if (in_array('menu-item-14', $classes)) {
$classes[] = 'current_page_parent';
}
break;
case 'tips':
// we're viewing a custom post type, so remove the 'current_page_xxx and current-menu-item' from all menu items.
$classes = array_filter($classes, "remove_parent_classes");
// add the current page class to a specific menu item (replace ###).
if (in_array('menu-item-23', $classes)) {
$classes[] = 'current_page_parent';
}
break;
}
return $classes;
}
add_filter('nav_menu_css_class', 'add_class_to_wp_nav_menu');
There's just one custom post type in the function, but I'm sure you can figure out how to add more. Got any questions, feel free to leave a comment! :)
