Using Editable List Controls

You can bind editable list controls to data parameters of the primitive array data type.

1. Add new data parameters strArray, intArray, and decArray of the respective types Text, Integer, and Decimal. All of these should be of array type.
2. Add three Text controls with labels Text List, Integer List, and Decimal List in to the form. Set the names of these controls to textList, integerList, and decimalList.

   For each of these controls:

   Go to the Properties tab and select the Edit as List check box.

   Go to the General tab and add a new binding for the Value that points to the value of the respective data parameter array.

3. In the form preview, you will see the three editable list controls.
4. Add a new button Add Item to the form.

   Add a new rule for this button and associate following action script for the Select event of this button. This script adds the last item into the list.

         var list = control.textList.getValue();
         list.push("New Value");
         control.textList.setValue(list);

5. Add a new button Delete Item to the form.

   Add a new rule for this button and associate the following action script for the Select event of this button. This script deletes the last item from the list.

         var list = control.textList.getValue();
         list.pop();
         control.textList.setValue(list);

6. For the text control named Text List, add the following validation script for the On Value Change event. This validation is successful when the item added in the list control starts with Text. Otherwise, a problem marker appears near the list control.

         var result = true;
         var arr = this.getValue();
         if (arr instanceof Array) {
            var length = arr.length;
            for (var i=0; (i<length) && result; i++) {
               if (arr[i].indexOf("Text")==-1) {
                  result = false;
                  break;
               }
            }
         }
         result;

   Also add an error message to be displayed in case the validation fails:

   Provide input that starts with Text.
