Question

无论我改变什么，我都无法在页面中看到我的gridview。我已经使用过Datasource和Databind，Visible是True，我想至少我应该只看到表而不是什么。另外，我很抱歉，我没有翻译这个，有些东西是西班牙语但我认为你会理解上下文，尽管名字是西班牙语。如果这是一个问题，我可以编辑和翻译。感谢。

Answer 1

您无法为网格设置数据绑定方法，

 grvRemates.DataSource= Agencia.Instancia().devolverRemates();
 grvRemates.DataBind();

ASP.NET Gridview未在页面中显示
