在您的 gvData _OnRowDataBound 上，检查条件并将每行的相应按钮 Visible 属性设置为 false。

            protected void gvData_OnRowDataBound(object sender, GridViewRowEventArgs e)
            {
                LinkButton lbClose = (LinkButton)e.Row.Cells[5].FindControl("lbClose");
                LinkButton lbEdit = (LinkButton)e.Row.Cells[5].FindControl("lbEdit");
                LinkButton lbDelete = (LinkButton)e.Row.Cells[5].FindControl("lbDelete");
                LinkButton lbWrite = (LinkButton)e.Row.Cells[5].FindControl("lbWrite");
                LinkButton lbRT = (LinkButton)e.Row.Cells[5].FindControl("lbRT");

                if(e.Row.Cells[1].Text=="Dessert")
                {
                    lbClose.Visible = false;
                    lbEdit.Visible = false;
                    lbDelete.Visible = false;
                }
                else
                {
                    lbWrite.Visible = false;
                    lbRT.Visible = false;
                }
            }
