Copy Code code as follows:
private void Datagridview_cellcontentclick (object sender, DataGridViewCellEventArgs e)
{
if (E.columnindex = = 0 && e.rowindex!=-1 &&!datagridview.rows[e.rowindex]. Isnewrow)
{
String name = Datagridview.rows[e.rowindex]. cells["DataGridViewTextBoxColumn1"]. Value.tostring ();
MessageBox.Show (name);
}
}
E.columnindex refers to the index of the column you clicked, E.rowindex is the index of the row, and if DataGridView has no data, E. rowindex for -1,cells["dataGridViewTextBoxColumn1" refers to the name listed in the DataGridView, can also be expressed in the index, written in Cells[0], that is, the 1th column.

GridViewRow row = this. Gridview.rows[index]; Get a line of GridViewRow
Label Label1 = (label) row. FindControl ("Label1");
