Xamarin.Forms - Choose list - xamarin

I don't know what is the real name of what I want to do, but I would like to make a list similar as this website link (Standard Select part at the top), does anyone can help me? I know it's something easy but I can't find what I want to do it for Xamarin. Maybe I don't search in the right direction, I assume it too!

There's no 1-1 implementation of a dropdown control in Xamarin.Forms but you'll get very close by using the Picker control.
Please notice that the default Picker control doesn't support binding so you might want to look for an extended version with that support.

There is no such thing built in Xamarin.Forms. You can choose one of the controls described in documentation.
To implement what you are looking for you will have to use Custom Renderer with control like this from Android. Of course for iOS you will have to use something different because there is no such control on iOS platform, but you can use this.

Have you looked at the Syncfusion AutoComplete control?
I think this is the closest you will get to what you are looking for.
They also provide a free community licence for developers

Date time format UI

My app shows many dates/times and I would like to allow user to create its own format using a friendly interface like the OSX system UI shown in image
I can't find any cocoa or CF API to show a similar panel, if possible I prefer don't re-implement it from the scratch.
Anyone can point me if this panel can be shown from standard API or if exists a ready to use component?
You're looking for NSTokenField, though you will need to do some modifications to make it work for your case.

Basic layout of appcelerator app

I creating my first appcelerator app and looking for some info on whether something is possible, and if so is it easy to implement.
I'm using Titanium SDK 2.0.1.
I'm trying to create a layout similar to the Stream window in the Google+ app for Android:
1: A large header (Can the navbar property of Ti.UI.createWindow be adjusted?)
2: Two tabs under the header (Would like to be able to adjust height of them if possible? Are there alternatives to Ti.UI.createTabGroup if this is not possible?)
The main content I can figure out easily enough I reckon.
Any examples or links on how to achieve this layout would be great.
Thanks
There is no way to do that type of NavBar in Android using the native Ti.UI.Window properties, but you can just create your own NavBar using a view and stick to the top of the window. For the tabs, I'd look at http://www.tomaspersson.com/2012/03/20/titanium-viewpager-module-now-available/ - I'm not sure it will have all the options you need, but it is a good starting point. Good luck!

How to make or use a standard Image Viewer for WP7

I want to make an app that shows pictures. But I want to be able to zoom in and out with gestures. I fixed this by including a toolkit into my project. But my actual question is, can I use or is there a control that's already created for me to show pictures like the picture library of the WP7 phone itself. I thought there wasn't but the Facebook app has a similar way of showing the pictures. Did Facebook rewrite the whole thing or is there a control somewhere that someone made?
The SlideView control in Telerik's RadControls for Windows Phone sounds like what you're looking for.
Have you tried a MultiScaleImage control? It's designed to work with multiple layers, but if you only specify one layer, it might suit what you're trying to do.

Graph view like iAd producer

Is there a way to use the same tree graph component as Apple uses for iAd producer? An equivalent would be fine, but if it's already in the cocoa framework, can somebody point to the specific component?
There's a framework for iPhone and Mac called Core Plot, available on Google Code. However, if you're looking to put graphs in the iAd itself, you'd need to find a Javascript-based framework.
Ah, you're looking for a visual layout control. Sorry, the only thing I know of like that is "EFLaceView", but there's no reliable download link to it anywhere. If you google it, you might find it. EFLaceView is a bit different from what's shown in the screenshot (it's more like what you see in Quartz Composer), but it's pretty similar.
Edit: Aha, there's a link to it here: any Cocoa control code that I can use that acts as a patch bay?

What is the best GUI library for blackberry java development?

What do you think is the most comprehensive and stable GUI library for Blackberry java development? I am currently using J4ME, anyone has any other experiences? A good GUI library should also have support for like grid controls, etc.
I donot think we have anything more advanced graphically.
I had to code for makin a grid control I remember.
Even the controls which exist doesn't look very good.
So I try making/using my own Custom modified controls everytime according to the theme.

The only way that I have found to do it is to roll your own, use the currently available TextField, LabelField etc. as the base and then make it look how you need it.
