推荐答案

如果你在后面的代码中创建下拉列表并且想要仅在代码后面禁用它，那么你应该使用Enabled属性并将其设置为false。

If you are creating dropdown in code behind and want to disable it in code behind only, then you should use "Enabled" property and set it to false.

ddlBrand0.Enabled=false

如果你试图禁用它JavaScript然后执行以下操作。

And if you are trying to disable it from JavaScript then do the following.

document.getElementById("clientdropdownid").disabled = true;
