If there are Accepted Answers, those will be shown by default. You can switch to 'All Replies' by selecting the tab below.
you can do so, by following steps:
a. fetch the control (dropdownlist/datadropdownlist) in java class
b. create an object of class Option (com.documentum.web.form.control.Option), like:
Option optionObj = new Option();
c. set the label and value for option (using setLabel and setValue method)
d. add option to dropdownlist / datadropdownlist control (using addOption method)
Or
Create list of Option objects
Use method setOptions to add list to dropdownlist or datadropdownlist control
Hi,
These are the utility methods I use for populating dropdowns and list boxes. Kindly change as required
public static void populateListBox(ListBox list, String[] labels, boolean isClearRequired) { list.setMutable(true); if (isClearRequired) list.clearOptions(); Option option = new Option(); option.setLabel(""); option.setValue(""); list.addOption(option); for (int i = 0; i < labels.length; i++) { if (isValidString(labels[i])) { option = new Option(); option.setLabel(labels[i]); option.setValue(labels[i]); list.addOption(option); } } list.setMutable(false); } //Comma seperated label and value to be provided public static void populateDropDown(DropDownList list, String label, String value) { list.setMutable(true); final String[] labels = label.split(","); final String[] values = value.split(","); Option option = null; for (int i = 0; i < labels.length; i++) { option = new Option(); option.setLabel(labels[i]); option.setValue(values[i]); list.addOption(option); } list.setMutable(false); } /** * Adds a special value as first item in the dropdown. This is used when you * want "Select" or blank string as first value. * * If isSpecialRequired is false then specialValue is ignored * * Also you can clean the dropdown before loading values * * */ public static void populateDropDown(DropDownList list, String[] values, boolean isSpecialRequired, String specialValue, boolean isClearRequired, boolean isSortRequired) { if (values != null) { list.setMutable(true); if (isSortRequired) Arrays.sort(values); if (isClearRequired) list.clearOptions(); Option option = null; if (isSpecialRequired && specialValue != null) { option = new Option(); option.setLabel(specialValue); option.setValue(specialValue); list.addOption(option); } for (int i = 0; i < values.length; i++) { if (isValidString(values[i])) { option = new Option(); option.setLabel(values[i]); option.setValue(values[i]); list.addOption(option); } } list.setMutable(false); } } public static void clearDropDown(DropDownList list) { list.setMutable(true); list.clearOptions(); list.setMutable(false); }
