[英]GridView Set ComboBox value Client side
I have a GridView with the following columns. 我有一个带有以下各列的GridView。
Parent ID has Child IDs. 家长ID有孩子ID。 If i Select Parent ID combobox as YES then all child values should be populated as YES.
如果我选择“父母ID”组合框为“是”,则所有子值应填充为“是”。
I want to do it on Client side using Java Script. 我想使用Java脚本在客户端进行操作。 Can you please guide me.
你能指导我吗?
