推荐答案

再次绑定该下拉列表，方法与您首先绑定的方法相同.
或
再次调用绑定下拉列表的相同方法.
谢谢

Bind that drop down again by same method by which you bind first.
or
Call same method again by which you bind dropdown.
Thanks

如果要使用任何函数填充/绑定下拉列表，则在删除按钮的click事件上再次调用同一函数.
例如.

if you are using any function to populate/bind the drop down list, then call the same function again at the click event of the delete button.
eg.

protected void btnDelete_Click(object sender, EventArgs e)
    {
        deleteData();
        dropdownlist1.items.clear();
        bind_DataToDropDown();

    }
