Problem with #select_filter and filterBy() not syncing

Inside the grid loading function, I am filtering a column by the text
‘Incomplete’ as shown below using the filterBy() function. That works great.

grdParticipants.clearAndLoad('...',function(){
.
.
grdParticipants.filterBy(grdParticipants.getColIndexById("Completed"),"Incomplete");
})

But there is a select dropdown filter in the column header created using #select_filter.
Though the column is filtered by ‘Incomplete’ text, the select filter does not preselect it(its blank).
Is there a way to set the text of this select filter to Incomplete? because it looks very confusing.

This is the expectable behavior.
Please, try to use the following solution instead of filterBy():
grdParticipants.getFilterElement(grdParticipants.getColIndexById(“Completed”)).value=“Incomplete”
grdParticipants.filterByAll();

Brilliant!

Thank you
