单击DataGridView中的行标题的事件

Question

什么是专门处理仅在DataGridView的行标题上进行的鼠标点击的事件？

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...
    }
