Visible/invisible Fields using Checkbox

If you face requirement of Visible/invisible Fields using Checkbox this post will help you. It is very simple process that i am showing in briefly step by step.

First we have to create a table that contain some fields according to figure 1 and have to keep in mind  that one field should be Enum Type and set its property “EnumType NoYesCombo”.

Figure 1 - Create a table with “Enum Type” field

Next, create a form according to figure 2 and set following property:

1. “Student_checkBox”

AutoDeclaration - “Yes”

DataSource – “Student”

DataField - “Fee”

2. Student_StudentId

AutoDeclaration - “Yes”

3. Student_Name

      AutoDeclaration - “Yes”

Figure 2 – Create form and override modified()

Finally, override “modified()” method on Student_CheckBox with following code:

public boolean modified()

{

    boolean ret;

    ret = super();

    if(Student_CheckBox.checked())

    {

        Student_StudentId.visible(false);

        Student_Name.visible(false);

     }

    else

    {

        Student_StudentId.visible(true);

        Student_Name.visible(true);

    }

    return ret;

}
