Kendo UI scheduler: make appointments that occur in the past 'read-only' - telerik

Is there a way to make appointments slots and grid cells that occur in the past read-only in the Kendo scheduler? It would be fantastic if the grid was editable, but only for slots that occur in the future.
I would like appointments that occurred in the past to not be movable, resizable or destroyable.
Ideally, I would still be able to double click on them to load my custom form as read-only so people can still view the details of the reservation. I would then use template logic to make those fields read-only.

Just a mock-up of how I would do it... you'll probably have to do that with all the previously mentioned events though.
---> outside your scheduler but still accessible to it
var today = new Date(milliseconds);
---> events in your scheduler - in this case the edit option...
edit: function (e) {
if (kendo.toString(e.event.end, "fff") < today ) {
e.preventDefault();
}
else {
console.log("Hope that helps?")
}
}
Hope it helps!

The view area of ckEditor sometimes shows empty at the start

I am using the following directive to create a ckEditor view. There are other lines to the directive to save the data but these are not included as saving always works for me.
app.directive('ckEditor', [function () {
return {
require: '?ngModel',
link: function ($scope, elm, attr, ngModel) {
var ck = ck = CKEDITOR.replace(elm[0]);
ngModel.$render = function (value) {
ck.setData(ngModel.$modelValue);
setTimeout(function () {
ck.setData(ngModel.$modelValue);
}, 1000);
}; }
};
}])
The window appears but almost always the first time around it is empty. Then after clicking the [SOURCE] button to show the source and clicking it again the window is populated with data.
I'm very sure that the ck.setData works as I tried a ck.getData and then logged the output to the console. However it seems like ck.setData does not make the data visible at the start.
Is there some way to force the view window contents to appear?
You can call render on the model at any time and it will simply do whatever you've told it to do. In your case, calling ngModel.$render() will grab the $modelValue and pass it to ck.setData(). Angular will automatically call $render whenever it needs to during its digest cycle (i.e. whenever it notices that the model has been updated). However, I have noticed that there are times when Angular doesn't update properly, especially in instances where the $modelValue is set prior to the directive being compiled.
So, you can simply call ngModel.$render() when your modal object is set. The only problem with that is you have to have access to the ngModel object to do that, which you don't have in your controller. My suggestion would be to do the following:
In your controller:
$scope.editRow = function (row, entityType) {
$scope.modal.data = row;
$scope.modal.visible = true;
...
...
// trigger event after $scope.modal is set
$scope.$emit('modalObjectSet', $scope.modal); //passing $scope.modal is optional
}
In your directive:
ngModel.$render = function (value) {
ck.setData(ngModel.$modelValue);
};
scope.$on('modalObjectSet', function(e, modalData){
// force a call to render
ngModel.$render();
});
Its not a particularly clean solution, but it should allow you to call $render whenever you need to. I hope that helps.
UPDATE: (after your update)
I wasn't aware that your controllers were nested. This can get really icky in Angular, but I'll try to provide a few possible solutions (given that I'm not able to see all your code and project layout). Scope events (as noted here) are specific to the nesting of the scope and only emit events to child scopes. Because of that, I would suggest trying one of the three following solutions (listed in order of my personal preference):
1) Reorganize your code to have a cleaner layout (less nesting of controllers) so that your scopes are direct decendants (rather than sibling controllers).
2) I'm going to assume that 1) wasn't possible. Next I would try to use the $scope.$broadcast() function. The specs for that are listed here as well. The difference between $emit and $broadcast is that $emit only sends event to child $scopes, while $broadcast will send events to both parent and child scopes.
3) Forget using $scope events in angular and just use generic javascript events (using a framework such as jQuery or even just roll your own as in the example here)
There's a fairly simple answer to the question. I checked the DOM and found out the data was getting loaded in fact all of the time. However it was not displaying in the Chrome browser. So the problem is more of a display issue with ckEditor. Strange solution seems to be to do a resize of the ckEditor window which then makes the text visible.
This is a strange issue with ckeditor when your ckeditor is hidden by default. Trying to show the editor has a 30% chance of the editor being uneditable and the editor data is cleared. If you are trying to hide/show your editor, use a css trick like position:absolute;left-9999px; to hide the editor and just return it back by css. This way, the ckeditor is not being removed in the DOM but is just positioned elsewhere.
Use this java script code that is very simple and effective.Note editor1 is my textarea id
<script>
$(function () {
CKEDITOR.timestamp= new Date();
CKEDITOR.replace('editor1');
});
</script>
Second way In controller ,when your query is fetch data from database then use th
is code after .success(function().
$http.get(url).success(function(){
CKEDITOR.replace('editor1');
});
I know, that this thread is dead for a year, but I got the same problem and I found another (still ugly) solution to this problem:
instance.setData(html, function(){
instance.setData(html);
});

Lazy loading list box, in a panorama page

I wanted to add a lazy loading list box(load content when swipe) in a panorama page in one of my windows phone 7 applications. I could however do it using a pivot page. I referred this link
But this is not working with panorama page. Can anyone please help me?
Okay, you're going to need to do one of two things: use the BCL Async package (basically adds async Tasks and such to WP7) or use a background worker. I highly suggest the BCL Async package, it's easy to get on Nuget.
Now, in your ViewModel (you are using MVVM, yes?) the property that it's bound to, let's call it Items should return an ObservableCollection of the item type you need. Now, here's where the magic happens. In the Getter of that property, return a new collection and use a task to fill it. Something like this:
public ObservableCollection<object> Items
{
get
{
ObservableCollection<object> retCollection = new ObservableCollection<object>();
FillCollection(retCollection);
return retCollection;
}
}
public async void FillCollection(ObservableCollection<object> collectionToFill)
{
Task.Factory.StartNew(() =>
{
foreach(object objectToAdd in collectionImGettingThisDataFrom)
{
// We do this using the Dispatcher to
// be sure to pop back into the UI thread.
Deployment.Current.Dispatcher.BeginInvoke(
() => collectionToFill.Add(objectToAdd));
}
}
}
Because FillCollection is async, the Get method will continue and return the current collection. On another thread, the Task that's created will find the data to add, then push it to the UI thread to add it into the collection. This way, you'll be able to lazy load the data only when you ask for it, without completely blocking your UI thread. If it turns out that it's still making your UI slow, you can add the line:
await TaskEx.Delay(25); // Some time in milliseconds. Too much and it will
// take a long time to load the list,
// too little and it will still bog down your UI.
At the end of the foreach block, but not in the Dispatcher invokation.
Happy coding!
Have you looked at the Telerik Rad Controls yet? They have all types of pull to refresh controls. I used them in a recent app I released called "Rad Libs". You can see the controls here http://www.telerik.com/products/windows-phone.aspx and you can also download an app that demos all of their controls. (Disclaimer: I have no affiliation with telerik. I stand to gain nothing from promoting them here)

MVC3 Submit Ajax Form

I've read lots of different posts on this topic and I will continue to do so and try various things. There's so much variation in the information though that, with my relative inexperience with MVC, etc, I feel like I'm going round in circles a bit.
Here's the situation. I am displaying a (Razor) view in an MVC3 app that contains records in a jqGrid. Double-clicking a record opens that record in a jQuery UI dialog. The original view contains just the that represents the dialog. The invoked action returns a partial view that becomes the content for the dialogue div.
function editItem(gridID, url) {
var rowID = getSelectedRowID(gridID);
if (rowID == null) {
alert('No row selected.\r\nPlease select a row and try again.');
return;
}
else {
var grid = getGrid(gridID);
$("#editDialogue").load(url + "/" + grid.SelectedRowID, function (html) {
$("#editDialogue")[0].value = html;
$("#editTabs").tabs();
$("#editDialogue").dialog("open");
});
}
}
That part works, although I have a feeling it could stand a little bit of cleanup. My real issue is later submitting the form contained in that dialog. It's supposed to post back to an action with the same name, which it does. That action is supposed to validate and save or return the same partial view with validation errors. At the moment I'm trying to just return the view without doing anything else. The view is returned alright but the entire page is replaced, instead of just the contents of the dialog.
I've tried various things, including using Ajax.BeginForm and specifying the id of the dialog div as the UpdateTargetId of the AjaxOptions. Nothing has worked so far. Note that the form being submitted is inside the div so it will be replaced too. Not sure if this is part of the problem.
I'm packing up for the day now so I thought I'd post and see what happens overnight before attacking the problem again in the morning.
jmcilhinney,
You were right to set the AjaxOptions.UpdateTargetId, but you also need to set AjaxOptions.InsertionMode to InsertionMode.Replace.
I had the same issue occurring as well. The fix was to make sure that the jquery.unobtrusive-ajax.is file is on the page. That fixed my issue. Just double check to be sure. I was confident I had all the js files, but found out I was missing that one.

Google Chrome Extension - How can I include a content script more than once?

I've been working on Chrome Extension for a website for the past couple of days. It's coming along really nicely but I've encountered a problem that you might be able to help with.
Here's an outline of what the extension does (this functionality is complete):
A user can enter their username and password into the extensions popup - and verify their user account for the particular website
When a user browses http://twitter.com a content script is dynamically included that manipulates the DOM to include an extra button next to each tweet displayed.
When a user clicks this button they are presented with a dialog box
I've made a lot of progress but here is my problem:
When a user visits Twitter the content script is activated and all tweets on the page get my new button - but if the user then clicks 'More...' and dynamically loads the next 20 tweets... these new additions to the page DOM do not get affected by the content script (because it is already loaded).
I could add an event listener to the 'More...' button so it then triggers the original content script again (and adds the new button) but i would have to predict the length of twitter's ajax request response.
I can't tap into their Ajax request that pulls in more tweets and call my addCurateButton() function once the request is complete.
What do you think is the best solution? (if there is one)
What you want to do is to re-execute your content-script every time the DOM is changed. Luckily there is an event for that. Have a look at the mutation event called DOMNodeInserted.
Rewrite your content script so that it attaches an event listener to the body of the DOM for the DOMNodeInserted event. See the example below:
var isActive = false;
/* Your function that injects your buttons */
var inject = function() {
if (isActive) {
console.log('INFO: Injection already active');
return;
}
try {
isActive = true;
//inject your buttons here
//for the sake of the example I just put an alert here.
alert("Hello. The DOM just changed.");
} catch(e) {
console.error("ERROR: " + e.toString());
} finally {
isActive = false;
}
};
document.body.addEventListener("DOMNodeInserted", inject, false);
The last line will add the event listener. When a page loads the event is triggered quite often so you should define a boolean (e.g. var isActive), that you initialize to false. Whenever the inject function is run check whether isActive == true and then abort the injection to not execute it too often at the same time.
Interacting with Ajax is probably the hardest thing to coax a content script to do, but I think you’re on the right track. There are a couple different approaches I’ve taken to solving this problem. In your case, though, I think a combination of the two approaches (which I’ll explain last) would be best.
Attach event listeners to the DOM to detect relevant changes. This solution is what you’ve suggested and introduces the race condition.
Continuously inspect the DOM for changes from inside a loop (preferably one executed with setInterval). This solution would be effective, but relatively inefficient.
The best-of-both-worlds approach would be to initiate the inspection loop only after the more button is pressed. This solution would both avoid the timing issue and be efficient.
You can attach an event-handler on the button, or link that is used for fetching more results. Then attach a function to it such that whenever the button is clicked, your extension removes all the buttons from DOM and starts over inserting them, or check weather your button exists in that particular class of DOM element or not and attach a button if it doesn't.

ModalPopUpExtender with checkbox validation

I have an AJAX Application that I have been working on. At this point in the development - I have a modalpopupextender with a warning message and an OK and Cancel button. I have just been tasked with changing this to be three checkboxes and having the OK button disabled until all three boxes have been checked. I'm having a difficult time trying to accomplish this. I'm not sure if I should use a checkboxlist control or just three checkboxes. I am also not sure if the enabling/disabling of the button should be handled through javascript or codebehind. I have tried a little of both - with no success so any guidance is very much appreciated.
Three checkboxs would seem to work quite well if you ask me.. you can have each check box run the same validation function to check on the other 2. Also, i have found that using 'this.disable=true' would work quite well for what you are trying to accomplish. This way everything is handled under JS and there is no need to use the codebehind.
function validate() {
if ('checkbox is not checked')
return;
if ('checkbox2 is not checked')
return;
if ('checkbox3 is not checked')
return;
submit.disabled = false;
}
