从数据网格视图单元格 C# 中的值更新标签文本
本文关键字：更新 标签 文本 数据网 数据 网格 视图 单元格 | 更新日期: 2023-09-27 18:31:59
>我有一个数据网格视图，我在其中输入时间小时，在它下面是一个页脚标签，位于 dataGridview 列的每一列末尾的页脚标签，用于计算每天的活动的总小时数，例如 |周一|周二|结婚
|1 | 2 | 3
|2 | 3 | 四
托特 3 5 6
对于正常条目，它工作正常，但是如果我在星期一时间的第一行中从 1 进行任何更改，我会将其更改为 5，那么只有该行总数即将到来
在这种情况下，总数将是 5 2 3
那是下一行在计算总数时没有考虑
请让我知道我错在哪里。

检查你的if部分，当不输入时，"montot"清除他的值，
添加其他：
if (lblMonTotal.Text.Contains(","))
{
strmontot = lblMonTotal.Text.Split(',');
}
if (lblMonTotal.Text.Contains("."))
{
strmontot = lblMonTotal.Text.Split('.');
}
else
{
strmontot = new string[2] { montot.ToString(), "0" };
}
else if (hr != 0)
{
lblMonTotal.Text = hr + ".0" + min;
}
编辑：他们将"else"更改为"else if"：
