如何根据文本框文本禁用gridview中的每个项目？

Question

如果预订关闭列值等于或大于textbox1文本，那么gridview中的book按钮将被禁用，每个gridview项目的预订关闭时间更长且等于textbox1时间..

怎么做？

您应该在GridView的rowbound事件处理程序中处理此问题。

更新＃1

protected void books_RowDataBound(object sender, GridViewRowEventArgs e) {
            if(e.Row.RowType == DataControlRowType.DataRow) {

                //Do this only if the textbox value is ....
                Button btn =  (( GridView )sender).FindControl("button");
                btn.Enabled = false;
            }
        }

更新＃2

Protected Sub books_RowDataBound(sender As Object, e As GridViewRowEventArgs)
 If e.Row.RowType = DataControlRowType.DataRow Then

  'Do this only if the textbox value is ....
  Dim btn As Button = DirectCast(sender, GridView).FindControl("button")
  btn.Enabled = False
 End If
End Sub
