Question

我有一个gridview，其中有一个特定的列Date。我已将列的Visible属性设置为false，因为我想在不同的页面条件下显示。请告诉我如何使用vb.net我的Date列应该在运行时显示或隐藏

更新

我目前的代码是

   If Not Page.User.Identity.Name = "bilal" Then
            GridView1.AutoGenerateEditButton = False

            GridView2.AutoGenerateEditButton = False
            GridView3.AutoGenerateEditButton = False
        Else
            GridView1.AutoGenerateEditButton = True
            GridView1.AutoGenerateColumns = True

            GridView1.DataBind()
            If GridView1.Columns.Count > 0 Then
                'assuming your date-column is the first '
                GridView1.Columns(3).Visible = True
            Else
                GridView1.HeaderRow.Cells(0).Visible = False
                For Each gvr As GridViewRow In GridView1.Rows
                    gvr.Cells(0).Visible = True
                Next
            End If



            GridView2.AutoGenerateEditButton = True
            GridView3.AutoGenerateEditButton = True

        End If

如果您将AutoGenerateColumns设置为True，则列数将为0，然后您需要循环行并显示/隐藏相应的单元格。否则，您可以使用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

Gridview显示并隐藏特定列
