如何突出显示DataGridView行或使其暂时发光？

Question

使用C#DataGridView我该怎么做:

1. 突出显示一行
2. 暂时发光(变黄几秒钟)

Answer 1

为了模拟用户选择一行,请使用

myDataGrid.Rows[n].IsSelected = true;

正如加布里埃尔所说的那样.

为了在DataGridView控件中临时突出显示DefaultCellStyle.BackColor颜色,请将该属性设置为您感兴趣的行所选择的颜色.然后System.Windows.Forms.Timer为您选择的时间段启用控件.当计时器的Tick事件触发时,禁用计时器并将行设置DefaultCellStyle.BackColor回原始颜色.

下面的简短示例适用于WinForm应用程序,该应用程序具有名为GlowDataGrid的DataGridView,名为GlowTimer的计时器和名为GlowButton的按钮.单击GlowButton时,DataGridView的第三行暂时呈现黄色两秒钟.

private void Form1_Load(object sender, EventArgs e)
    {
        // initialize datagrid with some values
        GlowDataGrid.Rows.Add(5);
        string[] names = new string[] { "Mary","James","Michael","Linda","Susan"};
        for(int i = 0; i < 5; i++)
        {
            GlowDataGrid[0, i].Value = names[i];
            GlowDataGrid[1, i].Value = i;
        }
    }

    private void GlowButton_Click(object sender, EventArgs e)
    {
        // set third row's back color to yellow
        GlowDataGrid.Rows[2].DefaultCellStyle.BackColor = Color.Yellow;
        // set glow interval to 2000 milliseconds
        GlowTimer.Interval = 2000;
        GlowTimer.Enabled = true;
    }

    private void GlowTimer_Tick(object sender, EventArgs e)
    {
        // disable timer and set the color back to white
        GlowTimer.Enabled = false;
        GlowDataGrid.Rows[2].DefaultCellStyle.BackColor = Color.White;
    }

Answer 2

您可以通过 someDataGridView.Rows[n].IsSelected = true; 突出显示“n”行；
