[Solved] General ComboBox questions

[Marc Simkin]

Hi:

I have two general questions about the combobox.

1) How do you set a default value used to instruct the user what to do.  For example, "select a group".  This value should appear in the input area of the combo.  I would expect it to disappear once the user starts to type something in the input area.

2) If the combobox is databound via Ajax, and calls a server method that returns a list of items.  How can I do additional filter of the data returned before it is placed in the listbox.?

thanks

marc

Hello Marc,

Straight onto your questions:

#1:
This is not a built-in feature, but it can be easily achieved using JavaScript. Check this code library which shows how to achieve your goal.

#2:
You will need to wire onDataBound event and modify component.data and rebind the component:

function dataBound() {
    var combobox = $(this).data("tComboBox");

   //var modify data
   // var data = combobox.data;


  //rebind combo
  // combobox.dataBind(data);
}

All the best,
