Noted your advise.

Generally in Ms Access VBA programming, In such situation where all the field in the form need to do some changes, then we use to write as below, a type of loop

Dim ctlMyControl As Control
For Each ctlMyControl In Me
If ctlMyControl.ControlType = acTextBox Or ctlMyControl.ControlType = acComboBox Then
ctlMyControl.BackColor = vbWhite
End If
Next ctlMyControl
Me.ECode.SetFocus
End If

Therefore, was expecting some thing like this.
As it will be a big task to edit all.

varText is not just a momentary snapshot, but a continuously updating value that remains alive and keeps changing by the codes you have written consecutively . Many fields that utilize it refer to the value of the last final state, which has been continuously updated.

Hi @MIA27

1. Of course, you need to write the name of the control where the event is happening.

Please input your control name(InputTextField ?).

The TextInput2 is just a name of the field that I used for this example.

The logic above runs when an event occurs in a text field, the event takes its text value and put it into a variable, then use that variable to fill the text field itself again.

2. If you use varText as a common variable for all the input Text fields, all the text in each field will change to the converted result of last input value (eg. DataCardValue22 , your last code)because all the fields refer to the varText. You need to define a separate variable for each field and assign that variable to use it.

Dear Kirkby,
Thank you for your advise.
Need to have below clarification from your side

a)
Your code
OnChange of InputTextField: UpdateContext({varText:Upper(TextInput2.Text)});
Here as per the code
InputTextField is a field where the on change event trigger if user changes the value
TextInput2.Text is the another field where the changes happens.
BUT what what InputTextField itself, to its own. if the user type lower case here.

Confused, as if needs to apply this it should trigger the code on the textField of its own.
I mean For example
TextInputBox1 - the code to remain on change property of its own. so user type in TextInputBox1 and once he leaves the field, the changes to happens, not to dependent on other field change

Please explain if I am wrong understanding.

B)
Issue is of All the Edit Form. All the Edit Form as TickMark Icon to Save the data.
It will be ok, if we use the code this icon, so user has to move to next, before it goes the code triggers to update all the field in the EditForm
Example
UpdateContext({varText:Upper(DataCardValue18.Value)
UpdateContext({varText:Upper(DataCardValue19.Valuet)
UpdateContext({varText:Upper(DataCardValue20.Value)
UpdateContext({varText:Upper(DataCardValue21.Value)
UpdateContext({varText:Upper(DataCardValue22.Value)

Please guide, if method is ok, then in trigger, all is getting updated and saved

Hi @MIA27

There are a huge number of input controls on the screen.

If it is possible to use "Upper(Self.Text)" in the Default property of all controls, that could make the work easier and eliminate repetitive tasks, but it doesn't work because of the occurrence of recursive calls. To avoid this situation, using individual variables is necessary, so there may not be a simpler way to write the code. Even if I try to create a collection and put the TextField contents into the collection through some processing, and then batch check and convert to uppercase, it inevitably comes back to using variables, making it difficult to simplify the code.

If you were to save data using Patch instead of a relatively simple SubmitForm, you would only need to apply the Upper function to all fields, which would make the process relatively simpler. However, this action happens in the backend, invisible to the user.

Dear Kirkby,

I noticed that I have to apply the code to each control of the edit form. Currently I am having around 52 fields in the edit form, Will have to apply 52 times,

Is there a way to apply the code on the whole edit form.
To save time.
As my plan is the apply on several screen's Edit form. It will too much time consuming

@MIA27

If you you want to inform users without auto correction, you can use a label next to the inputTextField like this

Text property of your Information label:

If(

IsMatch(TextInput2.Text, "[A-Z/0-9]+$"),

"Valid",

"Invalid: Accept only uppercase letter and digits"

)

Thanks

Hi @MIA27

Default of InputTextField: varText

OnChange of InputTextField: UpdateContext({varText:Upper(TextInput2.Text)});

//OnChange is triggered when the cursor moves from the InputTextField to somewhere else.

If you need to modify existing data, initialize varText with the previously stored value in OnVisible of the screen
