FrmIn Frmin = (FrmIn)this.Owner;

if (Frmin == null)

{

return;

}

Frmin.T_C_Name.Text = list.SelectedItems[0].SubItems[1].Text;

Frmin.T_C_ID.Text = list.SelectedItems[0].SubItems[0].Text;

this.Close();

}

=====================

datagridview 鼠标单击事件，给textbox赋值

private void dataGridViewX1_CellMouseClick(object sender, DataGridViewCellMouseEventArgs e)

{

buttonX1.Enabled = false;

T_R_No.Text = dataGridViewX1.Rows[e.RowIndex].Cells[0].Value.ToString();

C_RoomType.SelectedText = dataGridViewX1.Rows[e.RowIndex].Cells[3].Value.ToString();

C_RoomType.SelectedValue = dataGridViewX1.Rows[e.RowIndex].Cells[1].Value.ToString();

T_R_mark.Text = dataGridViewX1.Rows[e.RowIndex].Cells[4].Value.ToString();

// T_RF_Num.Text = roomfee.RF_num.ToString(); ;

}

======================

contextMenuStrip 控件右键快捷方式

private void listViewEx1_MouseClick(object sender, MouseEventArgs e)

{

if (e.Button == MouseButtons.Right && listViewEx1.SelectedItems.Count == 1)

li.SubItems[0].Text = ".....";

li.SubItems.Add(...);

......

listView1.Items.Add(li);

4. 点击ListView列表头进行排序

private void listView1_ColumnClick(object sender, ColumnClickEventArgs e)
{
   if (listView1.ListViewItemSorter == null)
      listView1.ListViewItemSorter = new ListViewItemComparer(e.Column);
   else
   {
      ListViewItemComparer comparer = listView1.ListViewItemSorter as ListViewItemComparer;
      if (comparer.SortColumn == e.Column)
      {
          if (comparer.Order == SortOrder.Ascending)
              comparer.Order = SortOrder.Descending;
          else
              comparer.Order = SortOrder.Ascending;
          listView1.Sort();
