If you've set AutoGenerateColumnsto True, the Column-Count will be 0, then you need to loop the rows and show/hide the appropriate cells. Otherwise you can use the Visibleproperty.
如果您已设置AutoGenerateColumns为True，则 Column-Count 将为 0，然后您需要循环行并显示/隐藏适当的单元格。否则，您可以使用该Visible属性。
GridView1.DataBind()
If GridView1.Columns.Count > 0 Then
'assuming your date-column is the 4.'
GridView1.Columns(3).Visible = True
Else
GridView1.HeaderRow.Cells(3).Visible = False
For Each gvr As GridViewRow In GridView1.Rows
gvr.Cells(3).Visible = True
Next
End If
