    If Session("priv") = "host" Then
        fname_txt.Visible = False
        lname_txt.Visible = False
        email_txt.Visible = False
        birthday_txt.Visible = False
        phone_txt.Visible = False
        adresss_txt.Visible = False
        Label2.Visible = False
        Label3.Visible = False
        Label4.Visible = False
        Label5.Visible = False
        Label6.Visible = False
        Label7.Visible = False
        btn_delete.Visible = False
        btn_new.Visible = False
        Btn_save.Visible = False
    End If
    If Not IsPostBack Then
        GridView1.DataSource = x.selectProfile()
        GridView1.DataBind()
    End If
End Sub

提前谢谢你

推荐答案

如果你想禁用这些控件你必须在gridview RowDataBoud事件上编写代码因为当我们运行项目时，首先在绑定gridview之前调用此事件。第一件事是如果你想用gridview控件执行一些操作，你必须首先找到控件，之后你将能够访问控件ID并处理它们如下：

IF you want to disable these controls you have to write code on gridview RowDataBoud event becz when we run project this event is called firstly before the bind gridview. and first thing is what if you wants to be perform some opertation with gridview controls you have to find the control firstly after that you will be able to access the control ID and handle them like:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            LinkButton linkbtn = (LinkButton)e.Row.FindControl("lnkbtn");
            linkbtn.Enabled = false;
        }
    }

i hope its helping to you.......:-)

make AutoPostBack =true如果你想给用户提供有限的访问权限，那么使用授权概念......

make AutoPostBack="true" and if you want to give user limited access then use Authorization concept...
