        public DateTime CreationTimeEnd { get; set; }
        public string User { get; set; }
        public string Computer { get; set; }
        public string Description { get; set; }

您的问题不是很清楚.

但是，据我了解，您可以根据在组合框中选择的内容来过滤数据网格.请参见此处 [

Your question is not very clear.

However, from what I understand you can filter your datagrid based on what you select in the combo box. See here [^] for a sample.

combobox包含选定项"属性，将该属性强制将其转换为eventdetail对象，然后发送给WCF:)

combobox contain Selected Item property cast that one to your eventdetail object and and send to the WCF :)
