Question

I have a gridview in which a specific column Date. I have set the Visible property of column to false because I want to show on different conditions of page. Please tell me how can I do it using vb.net that my Date column should show or hide at runtime

Update

My current code is

   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

If you’ve set AutoGenerateColumns to 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 Visible property.

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
