推荐答案

听起来很有意思，如果你必须重复这个过程，但只有两者都有按下按钮。



我认为按钮2被禁用直到点击1，然后当按下按钮1被禁用时，按钮2被启用。单击按钮2时，按钮1启用，按钮2再次禁用。



另一种方法是你需要跟踪哪一行没有填写第二列，并弄清楚你将如何处理，或者只是不添加任何东西并继续前进，不要禁用任何东西..



当然请确保您使用每个按钮订阅您的活动:)

Sounds kind of interesting, and if you have to repeat the process but only if both buttons were pressed.

I would think button 2 is disabled until 1 is clicked, then when hit button 1 is disabled, button 2 enabled. When button 2 is clicked, button 1 is enabled, and button 2 is again disabled.

The alternative being that you would need to keep track of which row did not get second column filled in and figure out how you would handle that, Or just not add anything and move on, don't disable anything..

Of course make sure you subscribe to your event with each button :)

private void button1_Click(object sender, EventArgs e){
    if (null != dgv1) {
        dgv1.Rows.Add();
        dgv1.Rows[dgv1.Rows.Count - 1].Cells[0].Value = "test name";
        button2.Enabled = true;
        button1.Enabled = false;
    }
}

private void button2_Click(object sender, EventArgs e) {
    if (null != dgv1) {
        dgv1.Rows[dgv1.Rows.Count - 1].Cells[1].Value = "1111";
        button2.Enabled = false;
        button1.Enabled = true;
    }
}

谢谢，但这很简单！我解决了！

现在我可以通过这个解决方案创建销售因素！ :-) ;-)

thanks but it was very simple ! i solved it !
now i can create a Sales Factor with this solution !!! :-) ;-)

int i =0 
private void button1_Click(object sender, EventArgs e)
{
dg1.Rows.Add("test nsme");
}

private void button2_Click(object sender, EventArgs e)
{
            if (row == 0)
            {
                dg1.Rows[0].Cells[1].Value = "test number";
            }
            else
            {
                i = i + 1;
                dg1.Rows[i].Cells[1].Value = "test number";
               
            }
row = Convert.ToInt32(dg1.Rows.Count.ToString()) ;
}
