5 个解决方案
#1
private void Form1_Load(object sender, EventArgs e)
{
dataGridView1.UserAddedRow+=new DataGridViewRowEventHandler(dataGridView1_UserAddedRow);
}
private int m_AddCount = 0;
private void dataGridView1_UserAddedRow(object sender, DataGridViewRowEventArgs e)
{
m_AddCount++;
if (m_AddCount == 4) dataGridView1.AllowUserToAddRows = false;
}
#2
做一个循环事件在DataGridView里的RowsAdded事件
for(int x=0;x<dgv.Rows.count; x++)
{
if(x>3)
关闭
else
打开
}
#3
dgv.RowsAdded += new DataGridViewRowsAddedEventHandler(dgvEvent);
dgv.RowsRemoved += new DataGridViewRowsAddedEventHandler(dgvEvent);
private void dgvEnvet()
{
for(int x=0;x<dgv.Rows.count; x++)
{
if(x>3)
dgv.AllowUserToAddRows = false;
else
dgv.AllowUserToAddRows = true;
}
}
#4
private void dataGridView1_UserAddedRow(object sender, DataGridViewRowEventArgs e)
{
if (dataGridView1.RowCount > 4)
dataGridView1.AllowUserToAddRows = false;
}
private void dataGridView1_UserDeletedRow(object sender, DataGridViewRowEventArgs e)
{
for (int i = dataGridView1.RowCount-1; i >=0; i--)
{
dataGridView1.Rows[i].Cells["土层编号"].Value = i + 1;
}
if (dataGridView1.RowCount < 4)
dataGridView1.AllowUserToAddRows = true;
}

只能用强这个字来附会;
为什么C#.net 不提供充足的事件,行添加之前的事件,硬是找不到;
谁来,找到一个类似的事件;
没有文献来说清楚他的事件链,这门语言没救了;
