Handle the DataGridView.SelectionChangedevent. Use the DataGridView.SelectedRowsproperty to get the selected rows collection.
处理DataGridView.SelectionChanged事件。使用DataGridView.SelectedRows属性获取选定的行集合。
private void dataGridView_SelectionChanged(object sender, EventArgs e)
{
// Update the text of TextBox controls.
textBox1.Text = dataGridView.SelectedRows[0].Cells[1].Value.ToString();
textBox2.Text = dataGridView.SelectedRows[0].Cells[2].Value.ToString();
....
}

Check the selected property of DataGridViewRow, it returns truefor selected else false.
检查 的 selected 属性DataGridViewRow，它返回trueselected else false。
bool isSelected = dataGridView1.Rows[e.RowIndex].Selected;

You can subscribe to the SelectionChanged event of the control and iterate through each selected row if multi-selection is enabled or just the first one if single-row selection only.
如果启用了多选，您可以订阅控件的 SelectionChanged 事件并遍历每个选定的行，或者如果仅单行选择，则只遍历第一个。
private void MyGridView_SelectionChanged(object sender, EventArgs e)
{
for (int i = 0; i < MyGridView.SelectedRows.Count; i++)
{
MyTextBox.Text = MyGridView.SelectedRows[i].Cells[0].Value.ToString(); //assuming column 0 is the cell you're looking for
// do your other stuff
}
}
More information can be found on the SelectedRowsproperty.
更多信息可以在SelectedRows属性中找到。
