I have a radcombobox and allowcustomtext is true. Is there a property to validate the entered text with the drop down items. Dropdown items are from database and I want if the entered text is different from database data to show error message.
Please try to attach the OnClientTextChange event of RadComboBox and compare the entered text with the items in the RadComboBox, if no match is found then display an alert message.
JavaScript:
functionValidate(sender, args) {
varflag = 0;
for(vari = 0; i < sender.get_items().get_count(); i++) {
