aspxgridview运行时设计命令列的按钮

有时我们需要在程序运行时让某些用户对某些记录没有修改的权限,只能查看,但有的记录又有修改的权限,此时就需要在运行的时候来设定命令行的按钮情况,

以下是官方解决方案:

Protected Sub ASPxGridView1_HtmlRowCreated(ByVal sender As Object, ByVal e AsDevExpress.Web.ASPxGridView.ASPxGridViewTableRowEventArgs) HandlesASPxGridView1.HtmlRowCreated

      If Not e.RowType = GridViewRowType.Data Then

          Exit Sub

      End If

      Try

          Dim cmdColumnIndex As Integer

          cmdColumnIndex = -1

          Dim cell AsDevExpress.Web.ASPxGridView.Rendering.GridViewTableCommandCell



          For inti As Integer = 0 To ASPxGridView1.Columns.Count - 1

              If TypeOf ASPxGridView1.Columns(inti) Is GridViewCommandColumnThen Then

                  cmdColumnIndex = inti

                  Exit For

              End If

          Next

          If cmdColumnIndex = -1 Then

              Return

          End If

          cell = TryCast(e.Row.Cells(cmdColumnIndex + ASPxGridView1.GroupCount), DevExpress.Web.ASPxGridView.Rendering.GridViewTableCommandCell)

          If cell Is Nothing Then

              Exit Sub

          End If





          For i As Integer = 0 To cell.Controls.Count - 1

              Dim Button AsDevExpress.Web.ASPxGridView.Rendering.GridViewCommandColumnButtonControl

              Button = cell.Controls(i)

              If Button.Button.ButtonType = ColumnCommandButtonType.Edit Then

                  Button.Visible = False

                  Select Case e.KeyValue Mod 2

                      ' Removed for development Launch of page.

                      Case 0

                          Button.Visible = True

                      Case Else

                          Button.Visible = False

                  End Select

              End If

          Next



      Catch Ex As Exception



          Throw Ex

      End Try

  End Sub
