推荐答案

假设该下拉列表包含以下顺序

Suppose the dropdownlist contains the follwing sequence

1.Select 
2.city
3.country

您正在选择城市，然后单击按钮，然后顺序应与以上相同.

要执行相同的操作
在按钮单击事件上编写以下代码.

this.DropDownList1.ClearSelection();

单击按钮后，您将获得与上述相同的顺序.

You are selecting city and click on button then the order should be like once again same as above.

To do the same
Write the following code on the button click event.

this.DropDownList1.ClearSelection();

After clicking on the button you will get the same sequence as above.

DropDownList1.ClearSelection();

Dropdownlist1.Selectedindex =0
