在要清除它的位置使用此代码

Use this code where you want to clear it

Gridview1.DataSource = null;
       Gridview1.DataBind();

如果每次更改下拉列表项时都更改了gridview的数据，则意味着...在下拉选择更改事件中添加

If you change the data of gridview whenever you change the dropdownlist item means...in your dropdown selection changed event add

Gridview1.DataBind();
