vb.net - GridView RowDataBound event makes my GridView slow

Question

I have a PopupExtender that shows some information when a button in the GridView is pressed. This button exists on every row.

I also have a DropDownList present in every row that is populated by querying a database. I do this because it may be populated with different items depending on the row.

The problem I have is that the PopupExtender is slow to pop-up because of the RowDataBound event of the GridView that repopulates the DDLs from the database when the PopupExtender's associated button is pressed.

How can I make the PopUpExtender pop-up faster?

Answer 1

您可能需要考虑 jQuery Dialog 而不是 Asp.Net ajax 弹出扩展器。 http://jqueryui.com/dialog/。

另外，你真的需要gridview吗，你可以试试ListView控件而不是GridView。
