I'm using a textbox on my Windows Phone 8 app. I want that the first character which will be insert by the user will be in upper case.
if (str.Length == 1)
str = str.ToUpper();
I've tried to handle TextChanged event on Textbox with the above code, but the cursor will move to the first position, so I can't insert more text at the right place.
So, how can I make the first letter of textbox to upper case?
You should set the InputScope property to Text. The first character will automatically be inserted in upper case, and the TextBox will get auto-correction, suggestions, and emoticons.
<TextBox InputScope="Text" />

Im working on a code in VB.NET wherein I scan a barcode(21 digit input) into a text box, and immediately, it’s supposed to show some data. I get the barcode input via a text box, which is supposed to contain the entire 21 digits, and I’m using the function textChanged() to see if the text box value has updated.
The problem is, the code runs after only the first value of the barcode gets read, and the rest of the values don’t reflect in the text box at all.
Is there any way I can get the entire 21 digits and then pursue the remainder of the code (note: it has to be automatic after the 21 digits are entered)
Code:
Private sub number_textChanged(sender as Object, E as EventArgs) handles number.TextChanged
If number.text.length =21 then
Value=number.text
End if
Send your textChanged() code, in that you can count then entered valued once reached 21 count then you can show 21 digit barcode. Or you can use textbox mouseout event, in that it will wait until you enter value fully, when you mouseout from textbox, it will trigger event.
Otherwise you can use javascript to get textbox value count and show after 21 digit.
function checklength() {
var len = document.getElementById("TextBox18").value.length;
if (len == 21) {
alert(document.getElementById("TextBox18").value);
}
}
and Textbox in source code add onkeyup event like this
<asp:TextBox ID="TextBox18" onKeyUp="checklenght()" runat="server"></asp:TextBox>
You can store that value in hidden value use in server side.
I am working on input text validation for an application in UWP. I am using a textbox for user input. Based on the letter inserted, I remove character if its a special character (%, $, ..) when text changing and fix the position of cursor by TextBoxName.SelectionStart. But in Korean language when input is from IME by pressing right control, my fixing cursor position using TextBoxName.SelectionStart is not working. It always moves cursor one position right that I set during TextChanging Event.
So, I want to know wheather the input is coming from IME (Pop up in the Image) or not?
I'm making a program whereby it takes text and 'encrypts' it. I managed to do the caeser cypher part, but another part was to get the string value in the encrypted text, and display the number of characters in it. I decided to get the text from a text box, and display it in a tabcontrol box. What would be the code to get the values from the textbox, list what they are, and how many times they appear in the text box?
use this code below; will gets you the character length in your textbox
TextBox1.TextLength
i've got two textboxes in my form.
According to title, when I write something in one textbox (a random one), i need that at the same time, in the other textbox a text (given in the code) appears.
1 letter for 1 letter
1)Example with random text:
1 textbox ) How are you?
2 textbox) Let's just c
2)Example with random text:
1 textbox ) What is the aim of the project?
2 textbox) Let's just chill out for a mome
thanks so much
You will need to determine which responses you would like to which questions. However, the tackle to letter for letter problem. I would use the substring method and get the length of the current text.
Dim Response as String = "Hello World!"
Private Sub Text(ByVal..) Handles Textbox1.changed
Textbox2.text = Response.Substring(0, Textbox1.text.length)
End Sub
As the text changes in the textbox you are typing in, this will output the response corresponding to the length of the text input. Since the event is textbox.changed, each character entered will update the second textbox
You need to use an event based code here. I would use a loop per stroke of the key and make the event "Key Press." Write the code onto the textbox you are inserting data into.
I have a textbox, textbox1, whose ReadOnly property is set to true. It is somewhat like an on-screen keyboard. When the user presses a button, I can add characters by using:
Textbox1.Text = Textbox1.Text & A
But, when the user wants to remove the text, which should work exactly like the Backspace key, the last character should be removed from the textbox.
I am ready to give up normal textbox and use richtextbox if there is any way ahead with the rich one.
How to remove last character of a textbox with a button?
The previously suggested SubString method is what I would have posted too. However, there is an alternative. The Remove method works by removing every character after the given index. For instance:
TextBox1.Text = Textbox1.Text.Remove(TextBox1.Text.Length - 1)
You can use the SubString method to get all but the last character, for instance:
TextBox1.Text = TextBox1.Text.SubString(0, TextBox1.Text.Length - 1)
The above functions such as Substring and Remove are not executed in Visual Basic 6 (or earlier versions). I recommend to use Mid function.
For instance,in this example last character of Hello is deleted and rest of word is saved in Text1
Text1=Mid("Hello",1, Len("Hello") - 1)
and result is Text1=Hell
