Hi Jack The Dreamer,

The “selectedIndex” property specifies the index of the displayed item. If you want to change the ComboBox’s default selection, you need to set this property during the widget’s initialization.

Thanks Peter

What I’m trying to do is when I update my database like updating birth place it will display in combobox by default after refreshing combobox

selectedIndex: 0 <= it will select the very first item

selectedIndex: (I want to assign the very last or highest index that was updated to my birthplace)

Thanks again

Hi Jack The Dreamer,

If you want to learn which is the highest index, you can do the following:

1. Use the jqxDataAdapter’s loadComplete callback. That is a callback which is called when the dataAdapter is loaded with data.
2. jqxDataAdapter has a field called “records” which contains the loaded data. As “records” is an Array, you can use the “length” property to get the number of loaded records.
3. In the loadComplete callback, you can do this:

$("#combobox").jqxComboBox({selectedIndex: dataAdapter.records.length-1});

Hope this helps.
