The handling of row selection events in DataGridView typically involves the following steps:

Add a row selection event handler when the form is loaded.

dataGridView1.SelectionChanged += DataGridView_SelectionChanged;

– Create an event handler for row selection.

private void DataGridView_SelectionChanged(object sender, EventArgs e)
{
    // 获取选定的行
    DataGridViewRow selectedRow = dataGridView1.CurrentRow;

    // 处理选定行的数据
    if (selectedRow != null)
    {
        string rowData = selectedRow.Cells[0].Value.ToString(); // 获取第一列数据
        // 进行相应的处理
    }
}

In the selected event handler, you can access the current selected row using the CurrentRow property and process the data of that row as needed.
