dev gridcontrol 单选框效果

  private void gridView1_CellValueChanging(object sender, DevExpress.XtraGrid.Views.Base.CellValueChangedEventArgs e)        {            //此处4是单选框所在的列号            if (e.Column.ColumnHandle != 4)            {                 return;            }            for (int i = 0; i < gridView1.DataRowCount; i++)            {                //非当前行 置为 未选中状态                if (i != e.RowHandle)                {                     //0表示 未选中                    gridView1.GetDataRow(i)[e.Column.ColumnHandle] = "0";                }            }        }

此时gridView1 .OptionsSelection.MultiSelect 设置与否都不影响结果。

方法二：

  #region gridView1_RowCellClick事件        private void gridView1_RowCellClick(object sender, DevExpress.XtraGrid.Views.Grid.RowCellClickEventArgs e)        {            if (e.Button == MouseButtons.Left) // 判断是否是用鼠标点击              {                DevExpress.XtraGrid.Views.Grid.ViewInfo.GridHitInfo ghi = gridView1.CalcHitInfo(new Point(e.X, e.Y));                if (ghi.InRow)  // 判断光标是否在行内                  {                    //清空勾选项                    for (int i = 0; i < gridView1.DataRowCount; i++)                    {                        if (gridView1.FocusedRowHandle != i)                        {                            gridView1.GetDataRow(i)["selected"] = false;                        }                    }                    if ((bool)gridView1.GetDataRow(ghi.RowHandle)["selected"] == true)                    {                        gridView1.GetDataRow(e.RowHandle)["selected"] = false;                    }                    else                    {                        gridView1.GetDataRow(e.RowHandle)["selected"] = true;                    }                }            }        }        #endregion  #region  单选框控制        private void gridView1_CellValueChanging(object sender, DevExpress.XtraGrid.Views.Base.CellValueChangedEventArgs e)        {            if (e.Column.ColumnHandle != 0)            {                return;            }            for (int i = 0; i < gridView1.DataRowCount; i++)            {                //非当前行 置为 未选中状态                  if (i != e.RowHandle)                {                    //0表示 未选中                      gridView1.GetDataRow(i)[e.Column.ColumnHandle] = "0";                }            }        }        #endregion
