如何从 datagridview 单元格检索文本并将其显示在按钮中？

Question

如何从 DataGridView 单元格检索文本并将其显示在按钮上。 基本上我的项目有两个表单（Form1 和 Form2）。

-在 Form1 中，我有两个按钮（Starter 和 Main）。这两个按钮在单击事件时都会调用数据库 sql 查询并将记录生成为按钮。

-在Form2中我有一个按钮（启动器）。此外，单击事件上的此按钮调用数据库 sql 查询并在 DatagridView 中生成记录。

现在，在Form2中，当我双击库存数量列下的单元格时，会弹出一个对话框，允许我在该特定单元格中输入数字。 让我们说 Row-1：

Soup     Starter     10     <Allways On Stock>

---

因此，基于此，我如何获取该 cell = 10 的值并将其显示在按钮的右下角（在此示例中）案例按钮汤） 像这样：

##############
#            #
#   Soup     #
#         10 #
##############

有人可以帮助我解决这个问题...

提前致谢...

亲切的问候

这里是datagridview的cellclick事件的代码

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
        {
            // make sure that the click was in the right column
            if (e.ColumnIndex == 2)  // I used 1 here because I didn't put a column for FoodType, you should use 2.
            {
                // Give it a value in case the cell is empty
                string cellContent = "0";
                if (this.dataGridView1[e.ColumnIndex, e.RowIndex].Value != null)
                {
                    cellContent = this.dataGridView1[e.ColumnIndex, e.RowIndex].Value.ToString();
                }

                using (InputBox ib = new InputBox("Enter new stock amount:", this.dataGridView1[0, e.RowIndex].Value.ToString(), cellContent))
                {
                    if (ib.ShowDialog() == DialogResult.OK)
                    {
                        this.dataGridView1[e.ColumnIndex, e.RowIndex].Value = ib.Result;
                        cellContent = ib.Result;
                    }
                }
            }
        }

这是在单元格中输入数量的InputBox对话框...

是我如何在 form1 上创建按钮然后获取数据库记录并为这些按钮分配值的代码

Answer 1

您可以将标签准确地放置在按钮顶部您想要的位置
然后更新标签

Answer 2

看看这个：

多行文本作为按钮标签 - Windows 窗体

当您获得值 10 时，尝试使用该值设置按钮文本属性。您应该进行一些格式化（相应地添加空格）以使文本适合按钮右下角的部分。

更详细的解释：

当弹出对话框时，您输入值 10。当您在数据网格单元格中设置此数字时（我认为您有某种事件处理程序来做这项工作），您还应该设置按钮的文本属性 btnSoup.Text = 10 在同一事件处理程序中。要对齐按钮中的文本，请使用我上面提供的链接。
