在 WinForm C# 中单击按钮时更改表格单元格颜色 [英] Change table cell color when a button is clicked in WinForm C#

问题描述

我对 Windows 窗体非常陌生，已经搜索了三天的答案，但没有成功.

I am very new to Windows Forms, have been searching for an answer for three days already but no luck.

我有一个按钮和一个包含多个单元格的表格.

I have a button and a table with multiple cells.

当按钮被点击时，我需要改变左上角单元格的颜色(索引 [0, 0])，但我不明白如何去做，因为 按钮的点击事件方法没有 TableLayoutCellPaintEventArgs 元素类型参数.

When the button is clicked, I need to change the color of the top left cell (index [0, 0]), but I don't understand how to do it since the button's on-click event method doesn't have TableLayoutCellPaintEventArgs element type parameter.

请告知如何操作.

推荐答案

感谢 Jackdaw 的回答，我找到了适合我的解决方案:

Thanks to Jackdaw's answer I was able to figure our a solution that worked for me:

我正在 tableLayoutPanel1_CellPaint 事件处理程序中更改表格单元格的颜色，然后使用此脚本从按钮的事件处理程序中调用它:

I am changing colors of the table cells in tableLayoutPanel1_CellPaint event handler, and then calling it from the button's event handler using this script:

this.tableLayoutPanel1.CellPaint += new TableLayoutCellPaintEventHandler(tableLayoutPanel1_CellPaint);

this.tableLayoutPanel1.CellPaint += new TableLayoutCellPaintEventHandler(tableLayoutPanel1_CellPaint);

我错过了 tableLayoutPanel1.Refresh();部分，但在寒鸦的回答之后，我注意到并能够添加它.现在一切正常.

I was missing tableLayoutPanel1.Refresh(); part, but after Jackdaw's answer I noticed and was able to add it. Everything is working correctly now.

完整的脚本如下所示:

    private void tableLayoutPanel1_CellPaint(object sender, TableLayoutCellPaintEventArgs e)
    {
        if (e.Row == 0 && e.Column == 2)
            e.Graphics.FillRectangle(Brushes.Red, e.CellBounds);
    }

    private void button1_Click(object sender, EventArgs e)
    {
        this.tableLayoutPanel1.CellPaint += new TableLayoutCellPaintEventHandler(tableLayoutPanel1_CellPaint);
        tableLayoutPanel1.Refresh();
    }
