酒店客房实时房态图刷新的问题？

[xie19sc]

房态图我用的方法是动态的向panle控件中添加lable，正着手与实现刷新功能的时候出现的点问题.

我用的方法是首先清空panel控件中的所有集合,然后再重新加载一次，这样做是可以，但是不是要想要的

因为这样做每次点刷新就会出现0.5秒的间隔，也就是0.5秒的闪屏，我要的效果不出现闪屏就可以直接刷新

不知道有没有高手做过或者懂得怎么弄，都来帮帮忙， 谢谢。


小弟是菜鸟，刚刚起步的。

用Panel绘制主要是考虑一些不确定因素，可以在里面再添加其他控件，以便显示不同的信息。

Good Luck

[sxldfang]

// 按楼主的思路
// 初始化panel
private void button4_Click(object sender, EventArgs e)
{
    for (int i = 0; i < 10; i++)
    {
        Label l = new Label();
        l.AutoSize = false;
        l.Width = 100;
        l.Height = 50;
        l.BackColor = Color.White;
        l.Left = (i % 4) * 110;
        l.Top = (i / 4) * 60;
        l.Name = "L" + i;
        l.Text = "L" + i;
        panel1.Controls.Add(l);
    }
}

//更新标签上的文字，仅举个例子，操作没问题
private void button5_Click(object sender, EventArgs e)
{
    panel1.Controls["L0"].Text = "Good";
    panel1.Controls["L5"].Text = "Afternoon";
}

直接刷新变更的部分

[xie19sc]

怎么刷

[xie19sc]

哪个高手进来帮帮忙，能说的详细点最好，谢谢了。

[修改一下昵称]

可以先隐藏panle控件一段时间 给一个友好的提示， “正在更新...”

[捷哥1999]

为什么不直接通过lable的name找到label，修改lable的text属性？

[rabbit5]

web 还是 winForm？

我不太清楚你的需求 ，如果是酒店的房态图，那么房间的位置应该是固定的，没必要清空panel控件的控件，只要把有变化的label的属性修改一下就可以了吧？

[zhoubupt]

直接刷新局部

[xie19sc]

不错不错 初步看了下，果然全是老手。 我先试试看， 在下感激不尽 ....
