Focus and UnFocus is not working in Xamarin Android - xamarin

I am using Entry control for numeric field as below structure
enter image description here
In above structure I am inheritance "XXXEditor" from Entry in renderer and binding dynamically with n numbers of items.
But when we enter something in numeric field and go to some other numeric field then enter something, when we come back to previous numeric text to make some changes so by that time if we try to enter something so textchange event will fire then
unfocus-->focus -->unfocus-->focus
in Nexus 5 but it will behave some thing in Samsung Galaxy S7.
Please suggest the solution to handle these events.
Thanks

Does Xamarin offer a native number picker that I can use with Xamarin.Forms?

I have used the standard picker which comes up with a box on the screen and allows me to select from a list.
But is there a native Xamarin picker that can be used just to pick numbers and populate a binder number? Something like I see on applications where a telephone keypad type thing displays with the numbers 1,2,3,4,5,6,7,8,9,0 and a backspace. This seems like a common kind of control for when a user wants to enter a number or dollar amount.
I look in the sample apps but could not find any example of this. If there is not one then is the only way to implement a series of numbers in a list ?
The kind of control I am interested in is one that when I click on an input field it opens up a box on the bottom of the screen with a number pad
Use an Entry with the Keyboard property set to Numeric
<Entry Keyboard="Numeric" />

LibGDX (Scene2D): Using Table with Labels to do a chat menu

I am trying to do a chat menu in my game using a Table and Labels but I can't seem to get the labels to behave the way I want them to.
By default they are drawn in the middle of the table. I added this settings to fix that but now when I add new labels they expand to fill the table, which I don't want.
After adding settings:
After adding a new label:
Note: The second message is there, it's jsut very faint. Just another bug I am having :/
Also, you may notice that the "Send" button is half off screen, trying to fix that too, but one problem at a time I guess.
By the way, the table is within a ScrollPane.

Getting the current value of a textbox in Access 2013 Custom Web App

in a List view I want a particular control (textbox) to have a red background color if it has a certain value. I have tried the following:
Click on the textbox then click the Data icon in the context sensitive controls that appear. I can then see that the name of the control is First_NameTextBox. I then click anywhere on the List view and click the Actions icon in the context controls that appear to the right of the view. I select "On Current". I then create two steps that should be executed whenever a new record is activated:
If [First_NameTextBox] = "somevalue" Then
SetProperty
Control Name [First_NameTextBox]
Property BackColor
Value #FF0000
End If
However, this turns the textbox red no matter what the value in First_NameTextBox is. How do I reference the CURRENT value of the textbox?
Conditional formatting based on a field value is not available for the List View in a Web App.
If you've built web pages (with or without a templating engine), the design limitations of Access can be frustrating.
Another kind of frustration comes from moving a form in Access from the native Access environment to a browser-based display.
I've felt the first kind of frustration, but so far I've avoided the second kind. I keep MS Access and HTML-rendered forms far away from each other.
Conditional Formatting in the List View of Access Web Apps is Available its just way harder than it should be.
Input "If Statement" under the "Current Macro" by clicking outside any text box or label then traveling to the top right of the view and you will see the Lightning bolt which allows two options, "On Load" and "On Current".
SELECT ON CURRENT
Don't forget You will need to set the control back to the original color by using the else. (also, for some reason I have to flip the Colors so where you would think red would go, Put White.
Example:
IF = "" True Then
White
Else
Red
END IF /DONT ASK ME WHY!
Summary: your Code is Sound, Just input it under the Views Current Macro Location
This is my first post, i spent DAYS looking for this information and found in the deep google somewhere so i hope this helps you.

NSStepper ignores current NSTextField value

I have the same initial problem as described in Integrate NSStepper with NSTextField:
I need to have a NSTextField working with a NSStepper as being one control so that I can edit an integer value either by changing it directly on the text field or using the stepper up/down arrows.
Using bindings as commented on by carlosb results in a usable UI. However, in the initial question carlosb describes the following:
Problem is that if I edit the text field then click the stepper again it will forget about the value I manually edited and use the stepper's internal value.
This is why I am posting a variation on this question again. carlosb's use of bindings doesn't solve this problem. This happens in both the current project I am working on and a test project I have created. The test project can be found at GitHub. You can download it there (even without git) via the "Download Source" button in the top right.
Is there a clean way to solve this issue?
Text fields and sliders are both in the view layer of the MVC pattern. You'll have much better results by binding both of those views to a property of your controller.
Your problem is that that the editing isn't ended until you press return or the field loses focus (so the number is never actually changed). If you press return or leave the field after editing, you'll see it works as expected.
One solution is to check the "Continuously Updates Value" option in the text field's value binding and check the "Continuous" option in the text field's attributes.
This will make sure the value is being updated as it's typed, so an immediate click on the stepper will reflect these changes.

cocoa + what ui element should i use?

I am developing an app which has a text field box. so when i am entering text, it should search the database and give me suggestions just like google search. like if i have entered letter 'a', it should have a box like thing below text field with all names starting with letter 'a'. then if i have entered letter 'b', it should resize the box and give names that start with 'ab' and so on.
I was planning to use a table view below the text field which reloads itself as and when new thing is entered into text field. but i dont know how to resize the table view depending on number of suggestions. So is there any other ui element which suits this kind of situations?
Also how do i detect a new alphabet or number entered into text field so that i can filter out suggestions like is there any such notification? what i mean to say is say i entered letter 'a' so now the string value of text field is 'a' and now i entered say 'b'. so now the string value changed to 'ab'. how do i detect this? i think textDidChange notification will do this for me.
Thanks
You can use an NSComboBox for auto-completing lists like you describe. NSComboBox is a subclass of NSControl so you can use the -controlTextDidChange: delegate method to detect changes in the text that the user types. Make sure you set the control to "continuous" in Interface Builder or call [comboBox setContinuous:YES].
If, for whatever reason, you find that a combo box is inappropriate for your situation, you can implement the list of completions as a child window of the control's window, with a headerless table view in it. Then you would programmatically resize that window as the number of possible completions changes.
