根据日期禁用对gridview的更新

Question

我正在Visual Studio中编写一个Web应用程序，其中使用实体从SQL Server 2012读取数据。如果periodstart大于当前日期，我需要在前端或数据库中检查PeriodStart（Date Field）与当前日期（System）的代码，用户必须能够编辑它，如果不是用户必须无法做任何消息应该出现的事情。

你可以试试这个

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) {
        if (e.Row.RowType == DataControlRowType.DataRow) {
            // assuming the the ShowEditLink resides in the first column of Grid
            //just changed the index of cells to where the EditLink resides
            LinkButton lb = (LinkButton)e.Row.Cells[0].Controls[0];

            //if you are displaying the PeriodStart in the Grid using BoundField
            //Cells[1] means you are displaying the date in second column, just change the index
            //where you display the date
            DateTime periodStart = Convert.ToDateTime(e.Row.Cells[1].Text);
            if (lb != null) {
                if (periodStart > DateTime.Now)
                    lb.Visible = true;
                else
                    lb.Visible = false;
         }
    }
}
