Question

I have a grid with to columns. The second column has editor with xtype: combobox. So here is my grid: grid

I want to clear my second row's combobox when first combobox is changed. I tried do this with edit( editor, e, eOpts ) , but i'm a little confusing when i try retrieve second combobox. Something like this:

var combobox1=editor.grid.columns[1].getEditor(e.record, 1)

it gives me current combobox, so i can't take another combo. Can you help me, please

Answer 1

If you want to make row2 val2 blank, you first have to get the record of the second row from the store, you can do that by:

If you know the second row id:

secondRecord = grid.getStore().getById(ROW2_ID)

If you know the row index:

secondRecord = grid.getStore().getAt(1)

and then you just do

secondRecord.set(VAL2_FIELD_NAME, "")
