    If I understand your requirement correctly, you don't want to do "Filtering String Edit", which is the title of your question. You want to update Contract field when the value of Company field changes.

    If both fields are from the same table and you can change its code, you can override modifiedField() method, check if the field being changed is Company and then set the value of Contract (this.Contract = "whatever";).

    Hi Martin,

    Both of String edit is bounded and are not from the same table and also both of them are filled by lookup method.

    Now , I want to second String edit fill with value instead of "Select contract..."  after selection the first automatically.

    If they're from different tables, you shouldn't use modifiedField() on table. But you can override modify() of the form datasouce field and put your logic there. The assignment is trivial:

    nameOfTheDsContainingContract.Contract = "whatever";

    This will set the value to the active record in the datasource called nameOfTheDsContainingContract. I can't be more specific because you didn't mentioned any names.

    By the way, I'll update the title for you to match the actual question.

    I face with this error:

    Parentheses are required on a method call. Err:324

    It is my code:

    public void modified()
{
    super();
    PaymSched_ds.Name=element.design().controlName("ContractName").valueStr();
}

    If your intention is to put value to field Name of table PaymSched, your syntax should be:

    PaymSched.Name=element.design().controlName("ContractName").valueStr();


    PaymSched_ds.Name() returns the name of your form data source. And if you try to call that method without parenthesis, you will get a syntax error like you did.

    Hi Nikolaos,

    My error is solved but value of string edit does not change.

    What is the data source of your string edit? Are you sure it's PaymSched.Name? I'm not. If we are still talking about the screenshot of your first post, it looks like a payment schedule id, not payment schedule name. And what are you trying to do? Are you trying to create a new payment schedule? Are you trying to update an existing payment schedule? Are you trying to find an existing payment schedule.

    Please share your exact expected outcome.

    Saying "it doesn't change" is not sufficient. Use the debugger to analyze what's going on.

    By the way, why do you use element.design().controlName("ContractName").valueStr() instead of something like myTable.ContractName or at least ContractName.text()? It looks very complicated and error-prone. For example, the code would still compile if you renamed the control but it would throw an exception at runtime.

    If you ever have to use a hard-coded control name, use formControlStr() to get compile-time validation.

    My problem is solved.below is correct code:

    /// <summary>
/// This function is developed for filling Payment Schedule and Customer Posting Profile according of selection Leasing Contract Automatically.
/// </summary>
/// Created by h.karimi 1397/05/23
///
public boolean modified()
{
    boolean ret;
    
    ;

    ret = super();

    SalesTable.PaymentSched=element.design().controlName("ContractName").valueStr();
    SalesTable.PostingProfile=LeasingContract.PostingProfile;
    SalesTable_ds.refresh();
    
    return ret;
}

     Because of the string edit fill in lookup method and data field does not bound,I override modified method of first string edit.
