DataGridView 时间控件应用

第一步

  DateTimePickerm_zldtp = new DateTimePicker();

  Rectanglem_zlRectangle;

  publicUCWLZL()

        {

            InitializeComponent();

 

            this.dgvZLData.Controls.Add(m_zldtp);//把时间控件加入DataGridView

            m_zldtp.Visible = false;//先不让它显示

            m_zldtp.Format = DateTimePickerFormat.Custom;

            m_zldtp.CustomFormat = "yyyy-MM-dd";

            m_zldtp.TextChanged += newEventHandler(m_zldtp_TextChange);//为时间控件加入事件dtp_TextChange

        }

第二步

    private void m_zldtp_TextChange(objectsender, EventArgs e)

        {

            this.dgvZLData.CurrentCell.Value= m_zldtp.Text;

        }

第三步

        privatevoid dgvZLData_CellClick(object sender,DataGridViewCellEventArgse)

        {

            try

            {

                if(e.ColumnIndex == 0)    //如果DataGridView中第一列

                {

                    m_zlRectangle =dgvZLData.GetCellDisplayRectangle(e.ColumnIndex, e.RowIndex,true); //得到所在单元格位置和大小

                    m_zldtp.Size = newSize(m_zlRectangle.Width,m_zlRectangle.Height);//把单元格大小赋给时间控件

                    m_zldtp.Location = newPoint(m_zlRectangle.X,m_zlRectangle.Y); //把单元格位置赋给时间控件

                    m_zldtp.Visible = true;//可以显示控件了

 

                    if(this.dgvZLData.CurrentCell.Value !=null && this.dgvZLData.CurrentCell.Value.Equals(DBNull.Value) ==false)

                    {

                        m_zldtp.Value = Convert.ToDateTime(this.dgvZLData.CurrentCell.Value);

                    }

                    else

                    {

                        m_zldtp.Value = DateTime.Now;

                    }

                }

                else

                {

                    m_zldtp.Visible = false;

                }

            }

            catch(Exception ex)

            {

                Class_Log4Net.WriteError("UCWLZL+dgvZLData_CellClick()" +ex.Message + ex.Source);

            }

        }

第四部

        privatevoid dgvZLData_CellLeave(object sender,DataGridViewCellEventArgse)

        {

            if(e.ColumnIndex == 0)

            {

                if(this.dgvData.CurrentCell.Value ==null || this.dgvData.CurrentCell.Value.Equals(DBNull.Value) ==true)

                {

                    this.dgvData.CurrentCell.Value= m_dtp.Text;

                }

            }

        }

第五步

        privatevoid dgvZLData_ColumnWidthChanged(object sender,DataGridViewColumnEventArgse)

        {

            m_zldtp.Visible = false;

        }

 

        privatevoid dgvZLData_Scroll(objectsender,ScrollEventArgs e)

        {

            m_zldtp.Visible = false;

        }
