Get a Monotouch.Dialog InputElement for a password field - mono

I am trying to get the value from an EntryElement
var password = new EntryElement("Password","Password",null,true);
I have a StyledStringElement with a click event like
new Section()
{
new StyledStringElement ("Login", delegate {
Console.Write (string.Format("Password is {0}",password.Value));
Console.Write (string.Format("Email is {0}",email.Value));
})
When I click on the element I can see the email string value however the password is always null.
What do I need to do differently to get the password value?

make sure you have pressed return on the iPhone keyboard, if not the value will not saved

Get the caret position for Blazor text input

I am working on a Blazor textarea input. What I want to achieve is whenever user types "#" character, I am going to popup a small window and they can select something from it. Whatever they select, I will insert that text into the textarea, right after where they typed the "#".
I got this HTML:
<textarea rows="10" class="form-control" id="CSTemplate" #bind="original" #oninput="(e => InputHandler(e.Value))" #onkeypress="#(e => KeyWasPressed(e))"></textarea>
And the codes are:
protected void InputHandler(object value)
{
original = value.ToString();
}
private void KeyWasPressed(KeyboardEventArgs args)
{
if (args.Key == "#")
{
showVariables = true;
}
}
protected void AddVariable(string v)
{
original += v + " ";
showVariables = false;
}
This worked very well. The showVariables boolean is how I control the pop-up window and AddVariable function is how I add the selected text back to the textarea.
However, there is one small problem. If I've already typed certain text and then I go back to any previous position and typed "#", menu will still pop-up no problem, but when user selects the text and the insert is of course only appended to the end of the text. I am having trouble trying to get the exact caret position of when the "#" was so I only append the text right after the "#", not to the end of the input.
Thanks a lot!
I did fast demo app, check it https://github.com/Lupusa87/BlazorDisplayMenuAtCaret
I got it - I was able to use JSInterop to obtain the cursor position $('#CSTemplate').prop("selectionStart") and save the value in a variable. Then use this value later in the AddVariable function.
you can set your condition in InputHandler and when you are checking for the # to see if it's inputed you can also get the length to see that if it's just an # or it has some characters before or after it obviously when the length is 1 and value is # it means there is just an # and if length is more than one then ...

UWP - Validation on ContentDialog's PrimaryButtonClick?

My ContentDialog is styled like a login form. It verifies password via connection thru SQLite. So in the Primary button's auto-generated Click event I have something like below (I made it Async btw):
Dim deferral As ContentDialogButtonClickDeferral = args.GetDeferral
If Await conn.Table(Of UserAccount).Where(Function(a) a.Username = UsernameTextBox.Text).CountAsync = 0 Then
args.Cancel = True
Dim x As New Windows.UI.Popups.MessageDialog("Username does not exist!")
Await x.ShowAsync
Else
'Other conditions
End If
deferral.Complete()
Some researching got me to think the Deferral is needed for Async situations (to no avail). Currently, with the above code I am getting a Reflection.TargetInvocationException on the Await line.
What I want to achieve is display a MessageDialog if username does not exist; the ContentDialog remaining onscreen for the user to correct himself.
Thanks!
Replace the "UsernameTextBox.Text" with a hardcoded value and it should work.
Maybe bind the textbox with a TwoWay mode into a variable and then use that variable in that statement.

Dynamically setting passwordMask in Titanium

Since Titanium doesn't allow you to manually change the hintText colour of a textfield, I have to set hintText manually. Because of this, I have to dynamically change the passwordMask setting on one of fields I'm using.
However, I'm getting weird behaviour and I can't tell if I'm doing something wrong, or if it's a bug in Titanium.
So, here's my markup:
<TextField id="password" onFocus="passwordFocusEvent" onReturn="passwordReturnEvent" onBlur="passwordBlurEvent" value="password"></TextField>
And some of my controller code:
function passwordFocusEvent(e) {
slideViewUp();
if (e.value === 'password') {
e.source.setPasswordMask(true);
e.source.value = '';
}
}
function passwordBlurEvent(e) {
if (!e.value) {
e.source.setPasswordMask(false);
e.source.value = 'password';
}
}
function passwordReturnEvent(e) {
slideViewDown();
passwordBlurEvent(e);
}
What happens is bizarre. When I focus on the password field, it remains plain text. I enter some text, then click off to another field, stays as plain text.
I click back to the password field, it's STILL plain text.
Now here's the weirdness. Up to this point, I would just assume it's not working. However, when I click off this second time, the passwordMask is set.
Major WTF.
I even tried targeting the field directly using $.password.passwordMask = true; but same thing.
Unfortunately, you cant do this. According to the docs on Ti.UI.TextField in the fine print;
Note: on iOS, passwordMask must be specified when this text field is created.
Its not all bad news though, there are a couple ways you can approach this, one option is to make the password mask yourself, by listening to the change event:
var theStoredPassword = '';
$.password.addEventListener('change', function(e) {
var newpass = e.source.value;
if(newpass.length < theStoredPassword.length) {
// Character deleted from end
theStoredPassword = theStoredPassword.substring(0, theStoredPassword.length-1);
} else {
// Character added to end
theStoredPassword += newpass.substring(newpass.length-1);
}
// Mask the text with unicode ● BLACK CIRCLE, 25CF
$.password.value = new Array(newpass.length + 1).join('●');
});
Another option, would be to have two text fields and swap them out whenever the user focuses the password field, the top one would have the custom hinttext, the bottom one would be passwordMasked. In fact thats probably way easier than what I just coded up. :-)

retrieving user input from a text field

What is the best way to retrieve user-input text from a text field on Submit button press? I am having issues with the listener, because it doesn't return anything (located in my gui class). I need to somehow retrieve what the user inputs, then return to the main class, and decide from there what to do with the user input. an example code would be nice!
You can attach a listener with your button and override its actionPerformed(). Inside actionPerformed(), you can retrieve the value entered in the text field.
Something like this :
button.addActionListener(new ActionListener (){
public void actionPerformed(ActionEvent evt) {
String text = textField.getText();
}
};)

Dojo OnKeyPress Handler: TextBox value is blank

I have a Dojo form that does not contain a submit button. Instead, I added an onkeypress handler to calls a method when Enter is pressed. The problem I am having is that when I hit enter before blurring off the current field, the _process method thinks that field is empty.
Or in other words: type in field1. hit tab. type in field2. hit enter. field2 is blank unless i click off the field or shift-tab back.
Any ideas?
dojo.connect(dijit.byId("fkrform"),"onKeyPress",function(e) {
if (e.keyCode == dojo.keys.ENTER) {
_process();
}
and the method it calls:
function _process()
{
var field1 = dijit.byId("field1").value;
var field2 = dijit.byId("field2").value;
alert(username);
alert(password);
...do stuff...
}
The fields are of dojoType: dijit.form.TextBox, and the form is: dijit.form.Form
Use dijit.byId('field1').get('value') instead of directly try to access the property "value". In your example you saved the value in the variable field1 and field2 and in the alert you use the variable username and password could be the answer why you don't get anything. But you still should use the get method to get a property instead of directly access the property.
When you press "Enter" your form will submit. So you need to connect to the "onSubmit" event on the form, instead of onkeyPress or onKeyUp.
The first example i created prints the value of the input box on every key someone pressed in the console.
http://jsfiddle.net/a8FHg/
But what you really wanted was hooking into the submit. I modified the example. The new example connects to "onSubmit" and creates an alert box with the text of the user input.
http://jsfiddle.net/a8FHg/1/
For completness if jsfiddle doesn't work some day. You JavaScript should looks like this.
dojo.ready(function(){
var form = dijit.byId('form');
var box = dijit.byId('box');
var submit = function(event) {
dojo.stopEvent(event);
alert("User input was " + box.get('value'));
};
dojo.connect(form, 'onSubmit', submit);
});
Assuming your form in your HTML has the id form and your box have the id box.
