Hi all. I have a GridView that has over 200 rows. I want to change the background color where my Reference number is duplicates. I bind the data to my GridView in my code behind.
How do you do it?

Your help would be appreciated :-)

推荐答案

如有可能，更改查询以使用group by包括出现次数.
然后您可以直接使用RowDataBound事件

Change your query to include count of occurrence using group by, if possible.
Then you can directly use RowDataBound event

If (e.Row.DataItem("occurrence") > 1) Then
 e.Row.BackColor = Drawing.Color.Red
End If  

否则，您需要遍历各行，并检查它们是否重复并相应地设置BackColor.

Otherwise, you need to loop through rows, and check whether it is duplicate or not and set the BackColor accordingly.
