Combo filter

Suite and Optimus Suite 5

I have a combo filter in my grid, Is there a way to change the empty option (which selects all items) to show “All” instead of nothing?

#2

Please, try the following:

mygrid.getFilterElement(colInd).setComboText("All");
#3

well it shows All one time after I select a item to filter I would like to have the option All to select
