Progressing loading is not working with ComboBoxItem. Below is how the field if defined :
{
name:"locationName",
editorType: "ComboBoxItem",
wrap:true,
width:500,
title: event_location,
prompt: event_location,
endRow:"true",
valueField:"value",
displayField:"value",
optionDataSource:"locationDS",
allowEmptyValue: false,
filterLocally: false,
cachePickListResults: false
}
We are not setting endRow so that call ComboBoxItem should keep calling backend when user types in but backend calls stop after typing few letter. After removing some letters, call again goes back to the backend but stops again when typing ahead, this does not let user filter the full dataset that backend has. We are using this filter locations which has huge dataset which can not be loaded on UI all at once.
