< BLOCKQUOTE>有趣。你能告诉我们你用来从数据库中获取值并将其绑定到控件的代码吗？您确定没有实现可能清除控件内容的控件事件吗？

I am using a dataset table to bind to a toolstripComboBox. The table has 20 rows in it. After binding the toolstripComboBox to the table it has an item count of 20. But nothing shows up in it. I am stumped. There are four columns in the table. I use one for the ValueMember and one for the DisplayMember. I'm sure this problem is something simple. Can someone help me out ?Thanks!

解决方案

interesting. Can you show us the code you use to get the values from the database and bind it to the control? Are you sure you have not implemented an event of the control which may clear out the contents of the control?
