I have a problem in Moodle: I cannot show and hide navigation.
I go to plugin => block => manage blocks, but this function cannot be useful:
You can hide or enable the Navigation block from Site Administration->Plugins->Blocks->Manage blocks. Which version of Moodle are you using?

When I embedd a view via iframe and activate the toolbar, it looks like this by default:
Is it possible to customize that views toolbar? In my case, I would like to have only the download button ("Herunterladen") and probably also the full screen (Vollbild).
You can't customize the toolbars BUT you CAN use the JavaScript API to make your own toolbar that behaves the way you'd like.

I am working on xamarin.forms. I am using Master detail page. In menupage of MasterDetailPage I have some menu items that are listed. At the bottom of the Menu list I placed a button on menu page. Now I need to open a popup on click of that button. I am trying with PopupLayout but not able to get any success.
Please tell me how I can open a custom popup box at the click of the button that is placed in menu page?

Without going into separate, native projects for all platforms you are targeting (such as Android, iOS, UWP...), you cannot pop out custom UI content over existing pages in Xamarin.Forms out of the box. You would need to bring in additional references or get creative with the AbsoluteLayout control.
Here are a few options you have:
Simple popup with message and or option selection
If all you need is a simple popup message or a list of buttons, you should look into the native DisplayAlert and DisplayActionSheet methods. They are built into Xamarin.Forms and work really well for these simple cases.
More complex popup dialogs
For anything more complex than that, there is the excellent UserDialogs project: ACR UserDialogs github page
It will give you support for various loading dialogs, date, time pickers, action sheet, success/info/error toasts and more.
Fully custom UI markup with AbsoluteLayout
There is a technique where by you prepare the underlying page with a root absoltue layout, which enables you to dynamically add new UI on top of all other controls on your page. This is fiddly and can ruin your performance if you are not careful. This is also the approach that the PopupLayout control that you mentioned uses. If done properly, this can be a good solution, but I don't recommend it as it involves additional complexity on each page that hosts the popup content.
Fully custom UI popup on native projects
Your most flexible option, as always, is to fall back to the native projects. This would involve coding up the popup logic on each separate platform that you are targeting, then using DependencyService (or one of the other techniques) to call into it from the shared project. For this you should look at samples and tutorials for popups on separate native platforms as it gets pretty broad and goes way outside the topic of this question.
I've been trying to find a solution but I can't find any.
I'll use basic examples so anyone who knows ionic can understand my problem well.
ionic start myApp tabs will create a new project with tabs ready to go.
Those tabs are Dashboard, Chat and Settings.
When you go to the Chat Tab you will then select a person to view its chat content (which directs you to the Chat-Detail Page in actuallity)
I wanted to hide the ion-tabs directive when I go to the chat-detail page so I can force the user to use the Back button instead of clicking anything on the ion-tabs.
Simply put : you will have a hard time doing that. At best it will not look good, IF you succeed to hide using css (I did it, and really, it's not pretty). Basically you would need to define a variable on the parent scope, that changes when entering the chat-detail state, and bind it to ng-class directives on multiple elements (the ion-tabs to hide it, the ion-content to translate it up to cover the area where the tabs were, and add some transition to make it not too brutal).
The logical thing to do would be to have the chat-detail state not being a child of the state containing the tabs. The problem you will have, though, is that there is a huge bug going to / from tabbed state. See details here : https://github.com/driftyco/ionic/issues/2997
At the end of this discussion you can find some posts by Jason and Jerrybels (that would be me), that could lead you on the right way to do it. Basically, you will have to get rid of the ion-tabs directive, and use Ionic's CSS for tabs instead, doing all the states manipulations yourself.
Good luck !
You can use "hidden" attribute of ion-tab like this -
<ion-tab hidden={{condition}}" />
Using this we can show/hide tab.
I have a tab bar for my app. One of the tab is an "action" tab for which I would like to use the official iPhone compose icon here as the tab item icon, is it allowed?
It is allowed provided you use it they way it was intended to be used. So if it is used to initiate a "compose" feature it would be allowed.
Apple will not hesitate to reject an app if any of their icons are used in unintended or nonstandard ways - and will site their HIG. So if you aren't sure, I would suggest just creating something very similar yourself.
The compose item is a bar button system item, not a tab bar item. I think you will run into HIG issues with it - it is typically used to summon a modal controller for you to create an item (usually a message).
That doesn't really fit as a tab bar item, which suggests a view of information that you can switch into or out of at any time.
In addition, the graphic may not be in the correct proportion or have the right properties to use in a tab bar.
I'm using the TabContainer/TabPanel components of the Ajax Control Toolkit.
I'd like to hide the tabs themselves and use a button elsewhere on the page to activate (bring to the front) one of the tabs without posting back to the server.
I can show and hide the tabs by grabbing their clientIDs and manually setting the visibility and display styles.
But is there a javascript function I can call to do this and perform whatever magic happens behind the scenes when I click an actual tab?
Example:
var tab = $find(“tabContainer’s ClientID”);
tab.set_activeTabIndex(1); // active the second tab panel
tab.getFirstTab().set_enabled(false); // disable the first panel
