在下拉列表属性中放入autopostback = true并处理事件选择索引已更改
在那一个像这样的绑定gridview
sqldataadapter da =新sqldataadapter(& quot;从tname中选择*其中colname =& quot; + ddl1.selectedvalue,cn);</pre>
put autopostback=true in dropdownlist properties and handle the event selectionindexchanged
in that one bind gridview like
sqldataadapter da=new sqldataadapter("select * from tname where colname="+ddl1.selectedvalue,cn);</pre>
