You just have to make sure that the value of rlvControllers._dataSource[itemIndex].FORMLAYOUT that you passed in the findItemByText() method exist in your dropdownlist DataTextField or else it won't work. One thing to note that you could also use the findItemByValue() method if you want to select the value based on the dropdownlist DataValueField. 这篇关于如何将值设置为radcombobox的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
