如何根据用户和管理员启用/禁用linkbutton？ [英] How to enable/disable linkbutton based on user and admin?

问题描述

我需要为管理员显示编辑按钮，而不是网格中的用户显示



我尝试过：

I need to show edit button for admin and not for user in Grid

What I have tried:

Dim lnkbtn As LinkButton = DirectCast(ProjectGrid.FindControl("btnEdit"), LinkButton)
        If Session("admin") Then
            lnkbtn.Enabled = True
        Else
            lnkbtn.Enabled = False
        End If

<asp:TemplateField>
                                                   <ItemTemplate>
                                                        <asp:LinkButton ID="btnEdit" runat="server" CommandName="Edit"  Text="Edit" Style="color:red" CommandArgument='<%#Eval("EmpID")%>'></asp:LinkButton>
                                                        <asp:HiddenField ID="hdndate" runat="server" Value='<%#Container.DataItem("date")%>' />
                                                   </ItemTemplate>
                                               </asp:TemplateField>

推荐答案

使用 OnRowDataBound 活动

use OnRowDataBound event

<asp:GridView ID="GridView1" runat="server"   OnRowDataBound="OnRowDataBound">

Protected Sub OnRowDataBound(sender As Object, e As GridViewRowEventArgs)
        If e.Row.RowType = DataControlRowType.DataRow Then
            Dim lnkbtn As LinkButton = DirectCast(e.Row.FindControl("btnEdit"), LinkButton)
            If Session("admin") Then
                lnkbtn.Enabled = True
            Else
                lnkbtn.Enabled = False
            End If 
        End If
    End Sub
