c# - 单击 DataGridView 中的行标题的事件

Question

专门处理仅在 DataGridView 的行标题上进行的鼠标单击的事件是什么？

如果没有，那么处理此类事件的替代方法是什么？

Answer 1

有一个新的 Winforms 项目并复制粘贴下面的代码：-

public partial class Form1 : Form
{
    public Form1()
    {
        var list = new List<Books>
                       {
                           new Books() {Title = "Harry Potter", TotalRating = 5},
                           new Books() {Title = "C#", TotalRating = 5}
                       };
        InitializeComponent();
        dataGridView1.AutoGenerateColumns = true;
        dataGridView1.DataSource = list;
        dataGridView1.RowHeaderMouseClick += new DataGridViewCellMouseEventHandler(OnRowHeaderMouseClick);
    }

    void OnRowHeaderMouseClick(object sender, DataGridViewCellMouseEventArgs e)
    {
        MessageBox.Show("Clicked RowHeader!");
    }
}

Answer 2

您可以通过以下代码获取行标题：

Private Sub dataGridView1_RowHeaderMouseClick( _
    ByVal sender As Object, ByVal e As DataGridViewCellMouseEventArgs) _
    Handles dataGridView1.RowHeaderMouseClick

    Me.dataGridView1.SelectionMode = _
        DataGridViewSelectionMode.RowHeaderSelect
    Me.dataGridView1.Rows(e.RowIndex).Selected = True

End Sub 

或者

void dataGridView1_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
    {
        //
        // Do something on double click, except when on the header.
        //
        if (e.RowIndex == -1)
        {
        //this is row header...
            some code here.
        }
       Code...
    }

Answer 3

有两个与单击行标题相关的事件。

1. RowHeaderMouseClick
2. RowHeaderMouseDoubleClick

Answer 4

private void dataGridView1_RowHeaderMouseClick(object sender, DataGridViewCellMouseEventArgs e)
        {
            try
            {
                DataGridViewRow dr = dataGridView1.SelectedRows[0];
                this.Hide();
                frmStock frm2 = new frmStock();
                frm2.Show();
                frm2.txtStockID.Text = dr.Cells[0].Value.ToString();
                frm2.txtConfigID.Text = dr.Cells[1].Value.ToString();
                frm2.txtProductname.Text = dr.Cells[2].Value.ToString();
                frm2.txtFeatures.Text = dr.Cells[3].Value.ToString();
                frm2.txtPrice.Text = dr.Cells[4].Value.ToString();
                frm2.txtQty.Text = dr.Cells[5].Value.ToString();
                frm2.txtTotalPrice.Text = dr.Cells[6].Value.ToString();
                frm2.dtpStockDate.Text = dr.Cells[7].Value.ToString();
                frm2.btnUpdate.Enabled = true;
                frm2.btnDelete.Enabled = true;
                frm2.btnSave.Enabled = false;
                frm2.label8.Text = label1.Text;
           }

            catch (Exception ex)
            {
                MessageBox.Show(ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
            }
        }
