在gvData _OnRowDataBound上，检查条件并为每一行设置相应的按钮Visible属性为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;
                }
            }

在过去，我已经创建了一个代码隐藏方法，用于计算并返回一个布尔值。

protected bool IsTransTypeDessert(string transType)
{
    return transType.ToLower() == "dessert";
}

然后在标记中，像这样调用该方法：

<asp:LinkButton ID="lbWrite" runat="server" CausesValidation="False" CommandName="WriteClicked" OnClick="Write_Click"
Visible='<%# IsTransTypeDessert(Eval("TRANSTYPE") != null ? Eval("TRANSTYPE").ToString() : "") %>'>Write</asp:LinkButton>

我不记得的一件事是IsTransTypeDessert是否需要返回字符串表示“true”或“false”，或者bool是否有效。测试将决定它。
