在DevExpress中没有触发子网格SelectionChanged事件
本文关键字：网格 SelectionChanged 事件 DevExpress | 更新日期: 2023-09-27 18:08:45
我有两个ASPxGridView控件- gvPatient和——gvOrdergvOrder放置在gvPatient的详细行模板中。我面临的问题是，我必须获得gvOrder(子)行对焦点行改变或选择改变的值。我有这些事件的代码，但这些事件不着火的行和焦点改变了子网格的选择。奇怪的是，这里的这些子网格事件触发gvPatient(parent)行选择和焦点改变。

需要设置属性SettingsBehavior。ProcessSelectionChangedOnServer和SettingsBehavior。ProcessFocusedRowChangedOnServer设置为true。
如果ProcessSelectionChangedOnServer属性被设置为false, ASPxClientGridView。SelectionChanged事件在客户端处理而不回发到服务器"
