我目前在 TAB 容器中有一个 asp.net 页面，该页面有一个搜索框，用于SqlDataSource在 asp.net 页面上没有附加的材料，一旦您单击搜索按钮，就会RadWindow弹出RadGrid显示详细信息。
在RadGrida 中UpdatePanel，一旦在 内单击 Edit 按钮，就会RadGrid弹出编辑窗口，但是当我尝试选择RadComboBoxCurrency、Company 和 Country 等任何一项时，没有回发发生，也不会在我单击时触发回发编辑模式下的Update按钮。
内部RadComboBox是RadGrid通过使用EditItemTemplate.
请看以下代码：
