Using a 'clicked' override on a button, I'd like to modify values in an Axapta form.
I'm able to get data from the form field using:
str strOld = Form_FieldName.valueStr();
I'm able to prepend text to the field using:
Form_FieldName.pasteText(strNew);
I can't seem to find a .clear method or .value= method. I'd like to replace the entire value in the field with new information.
Thanks
If the field is bound to a datasource, you have to modify the value in the datasource. If the field is bound to a variable, then modify the value of the variable itself. It is the easy an smart way to do it.
You can modify the value in the form control by using the .text() method. (The control have to be the AutoDeclaration property set to Yes). This is a setter-getter (parameter) type method used in AX. If no parameter is passed, it is user as getter (read). If you pass a value, this is a setter (write).
Hope this helps.

When I entered a value in the input box and submitted it, the mandatory item verification failed, and the system displayed a message indicating that a parameter was empty and instructed me to enter a value. The code for obtaining the input value is as follows:
(see the solution in column C)
can you give me some advice about it?
The possible cause is that the method for obtaining the value is incorrect. As a result, the value in the input box cannot be obtained.
Use the onchange event to assign a value to the model and obtain the value of the input box. The method is as follows:
Initialize the model.
data:{
accountValue:''
}
Bind an event to the input box.
<input #change="getAccountValue" value="{{accountValue}}"></input>
Assign a value.
getAccountValue: function(e) {
this.accountValue = e.value // Here, e.value instead of e.target.attr.value is used.
}
Refer to the official document instead of generating a JavaScript object for coding. A JavaScript object may lead to compatibility issues.
Currently, the data binding mode of the quick app is unidirectional.
The value entered in the input box does not change the value of accountValue in data.
If the value of the input box is changed by setting this.accountValue to xxx, the onchange event of the input will not be triggered.
In this.accountValue = xxx format, if the value of accountValue before and after the change is the same, the page will not be re-rendered.
in my myForm I call in a tableMY a displayMethod_fieldA.
In myForm I insered a some date in a DateEdit and I want to make a selection in table using the entered value. If I crete a displayMethod whit parameter I have an error.
Look like this code I get error:
display myEDTField displayMethod_fieldA (date _dateFromForm)
{
tableMY table;
select table
where table.item == this.item
&& table.dateTable == _dateFromForm;
return table.valueFieldA;
}
I have an error looklike this:
The display method has an incorrect parameter profile.
There is another way to display or set the value in my StrinEdit in Grid by method passing a parameter?
In web I saw the method modifier modifierMothod , but I need some more explanation. I don't know if this method is a right way.
Display methods are not designed with this feature.
display method for a table, form, report, or report design does not
have any parameters. For example: display Amount amount()
A display method for a form data source does require a parameter. You
use the
parameter to specify a table buffer. The type of the table buffer has
to match the type of the table in the form data source.

You can create the desired behaviour with an edit method (and setting the field to AllowEdit(false) or enabled(false).
The user enters input to fill the form, but I want to manually complete one field. I've tried using document.getElementById(certificate_request_commonname__row).createAttribute("value","abc");
but it doesn't work. In the form i'm adding data to a table. certificate_request is the name of the table and commonname is the column name. After I've looked on the web2py book I saw that I have to write: tablename_columnname__row. I've done that but it doesn't work. it always says to me: Empty string passed to getElementById(). Can anyone help?
certificate_request_commonname__row is just a wrapper element that contains the input element. Instead, you must identify the input element itself. Also, don't use createAttribute -- just set the .value attribute:
document.getElementById('certificate_request_commonname').value = 'abc'
I have a MATLAB GUI that shows all variable names in the base workspace in a popupmenu. The user can then choose a variable. This variable is then passed into a function. My problem is that I cannot find a way to grab the variable's value from the popupmenu. I am getting a cell, which I convert into a string.
data = get(handles.popupmenu1,'String');
data = data{1};
The problem is that if the variable is named n, then this will return 'n', with quotes, when I need it to return it without quotes. So, when I try to get the value, it does not work.
data = evalin('base','data');
How do I remove the quotes from the string?
It's probably not the most efficient way, especially if you have a lot of variables in the popup menu, but could you store your variables in the handles structure of the GUI, and when the user selects a variable name from the popup menu it triggers a switch/case scenario in which you use strcmp, for example, to evaluate what the variable is and thus get its value form the handles structure?
Or maybe create some kind of lookup table in the UserData property of the popup menu, so that each 'String' displayed in the popup menu can be related to the corresponding variable, after which you get its value and can then pass to other callbacks?
I can't test it with a simple script right now and that's only ideas; I'll check tomorrow unless someone comes up with an idea in the meantime!
Ok, you can try this:
data = get(handles.popupmenu1,'Value');
Use 'Value' instead of 'String'.
I am working with jasperserver and ireport. I have created multiselect input control. I need to access its id as well as name in report. How can I do that?
You cannot.
The value gets passed as the value of the relevant parameter (the parameter with exactly the same name as the input control). The label used in the input control (if any) does not get passed to the report. It's it's something that you want to pass to the report then you need to pass it as part of the value.
