添加CellClick事件
private void dataGridViewPlan_CellClick(object sender, DataGridViewCellEventArgs e)
{
if (e.RowIndex < 0)
return;
if (e.ColumnIndex < 0)
return;

string bb= dataGridViewPlan["columnName", e.RowIndex];
}
------解决方案--------------------------------------------------------
在GridView上应有一个选择LinkButton,则在GridView1的SelectedIndexChanged事件下输入:

protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
TextBox1.Text = GridView1.Rows[GridView1.SelectedIndex].Cells[列号].Text;
}
