getSelectedValue

[Jon E]

Hi

getSelectedValue seems to return the watermark text value if there is no selected item - is that behaviour correct?

Hi Prince

Ah OK.  I think this is down to the way that I have been clearing drop downs.  For various reason I handle cascading myself and when a parent changes I need to clear the chilkd drop down fields.  That is all OK but I am having issues with how to properly clear the children.  How do you clear the selected value AND empty the drop down of it's items?

Many thanks

Jon

I've managed to clear the items by way of reapplying an empty array to the datasource in the absence of a full clearItems function.

Still need to work out the proper way to deselect all items.  There is an unCheckAll but no unselectall....

Hi Jon,   

  

Thanks for your update.   

  

In order to deselect all the selected items in dropdownlist, you can make use of selectedItemIndex property. Set value -1 to selectedItemIndex property using setModel method.   

  

function clearAll(args) {   

          target.setModel({ selectedItemIndex: -1 });   

        }   

  

  

Another way of unselecting all items is by using clearText method.   

  

function clearAll(args) {   

          target.clearText();   

        }   

  

  

We have attached a Playground Sample for your convenience.   

  

Please let us know if you need more clarifications.
