推荐答案

1中为此编写程序.使组合框的自动回传属性正确.
2.写入SelectedIndex更改事件.

1. Make Autopostback proprty of combobox true.
2. Write in SelectedIndex changed event.

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
    {
        //Use DropDownList1.SelectedItem.ToString() to Get selected Text
        //Use DropDownList1.SelectedValue.ToString() to Get selected value

        //Execute query to fetch detail of seleted item
        //Set result to different textboxes
    
}
