Is there any feature that I can change valueField in combo box to upper case?

[prosper999]

So that it can match the record without the problem of case sensitive issue? I know that there may be records having the same value after changing the valueField to upper case

Hi prosper999,

did you already try having the actual request that uses the ComboBoxItem's value to be CI?
Where does the valueField come from? Is the ComboBoxItem databound? Has it a valueMap?
