在asp.net的gridview中动态更改图像 [英] Dynamically changing Image in gridview in asp.net
问题描述
大家好,
我有一个gridview,其中有一个imagebutton列,我使用gridview_RowDataBound事件从sql中存储在表中的路径动态绑定此图像列和图像.
但是现在当我单击imagebutton时,将一些参数传递给sql并更改了图像的路径,现在我想要的是通过再次获取图像的路径来更新网格视图imagebutton的图像.
请帮我如何实现这个目标!
问候,

推荐答案
在单击imagebutton
时使用ItemCommand
事件.
在ItemCommand
事件中..
Use theItemCommand
event when you click theimagebutton
.
InItemCommand
event..
dim imgButton as ImageButton
imgButton = ctype(sender,ImageButton)
' Pull your image path from sql store it in a string lsPath
imgButton.ImageUrl = server.mappath(lsPath)
-就是这样..希望对您有帮助..
