i要求在datagrid中我有一个下拉项目ABC和Others

推荐答案

你是如何制作文本的？框可见？如果使用javascript然后使用getElementById获取DropDown并通过设置disabled属性禁用它



执行如下操作：

How are you making the text box visible?? If using javascript then use the getElementById to get the DropDown and disable it by setting the disabled attribute

Do it as below:

document.getElementById(''<%= DropDownList1.ClientID %>'').disabled=false;

希望有所帮助：）

Hope it helps :)
