DataGridView的具體應用(1)-右鍵單擊後選中所在行及彈出上下文菜單,通過事件捕獲所選行的ID號及單元格內容

1、DataGridView中實現右鍵單擊後選中所在行及彈出上下文菜單
首先對dataGridView1添加RowContextMenuStripNeeded事件，然後新建一個DataGridViewRow，通過e.RowIndex捕獲鼠標右鍵單擊的行信息，清除所有選中的行，將鼠標右鍵捕獲到的行設爲選中。
在這裏通過dataGridViewRow1.Cells["fullNameDataGridViewTextBoxColumn"].Value將所選單元格的內容傳給變量，附代碼如下。
private void dataGridView1_RowContextMenuStripNeeded(object sender, DataGridViewRowContextMenuStripNeededEventArgs e)
{
DataGridViewRow dataGridViewRow1 = dataGridView1.Rows[e.RowIndex];
dataGridView1.ClearSelection();
dataGridViewRow1.Selected = true;
toolStripMenuItem1.Enabled = true;
fullName = dataGridViewRow1.Cells["fullNameDataGridViewTextBoxColumn"].Value as string;
// if ((dataGridViewRow1.Cells["Title"].Value.ToString() ==
//"Sales Manager") ||
//(dataGridViewRow1.Cells["Title"].Value.ToString() ==
//"Vice President, Sales"))
// {
// e.ContextMenuStrip = managerMenuStrip;
// }
// else
// {
// e.ContextMenuStrip = employeeMenuStrip;
// }
// contextMenuRowIndex = e.RowIndex;
}

2、DataGridView中通過事件捕獲所選行的ID號及單元格內容
主要是通過dataGridView1.Rows[dataGridView1.CurrentCellAddress.Y].Cells["列名"].Value捕獲鼠標單擊的行及指定列的值。
fullName = dataGridView1.Rows[dataGridView1.CurrentCellAddress.Y].Cells["fullNameDataGridViewTextBoxColumn"].Value as string;
if (fullName != null)
{
MessageBox.Show(fullName);
}
