Keep displayField on Ext.form.Combobox in EditorGridPanel after selecting item?

Question

I am using an Ext.form.Combobox on a column model editor, and this ColumnModel is put in to an EditorGridPanel. After I select an item in combobox, the text displayed on combobox is always the valueField, not displayField. How can I keep the displayField on combobox in EditorGridPanel after selecting any item? Thank you so much.

You need to use the renderer method for the column to display the desired text.

renderer: function(val){
    // select the display text for val from the combobox's store
    return display text;
}
