c# - 如何从 datagridview 单元格中检索文本并将其显示在按钮中？

Question

如何从 DataGridView 单元格中检索文本并将其显示在按钮上。 基本上我的项目有两种形式(Form1 和 Form2)。

-在 Form1 中，我有两个按钮(Starter 和 Main)。这两个按钮都有点击事件，它们调用数据库 sql 查询并生成按钮形式的记录。

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

现在在 Form2 中，当我在 Quantity In Stock 列下的单元格内双击时，会弹出一个对话框，允许我在那个特定的位置输入数字细胞。 假设第 1 行:

Soup     Starter     10     <Allways On Stock>

---

因此，基于此，我如何获取 cell = 10 的值并将其显示在按钮的右下角(在本例中为按钮 Soup) 像这样:

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

有人可以帮我解决这个问题....

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;
                    }
                }
            }
        }

这是用于在单元格中输入数量的 InputBox 对话框...

您可以在按钮顶部的确切位置放置一个标签 然后更新标签
