Farpoint Spread 常用屬性

1 取得當前行號、列號。

 

int row=e.Row; 
int count=e.Count;
或者：
int rowindex = fpSpread1.ActiveSheet.ActiveRowIndex;
int columnindex = fpSpread1.ActiveSheet.ActiveColumnIndex;

2 單擊一行變顏色。 

private void spdResult_CellClick(object sender, FarPoint.Win.Spread.CellClickEventArgs e)
  {
   //單擊Spread列頭時，什么也不處理

   if(!e.ColumnHeader)
   {
    if(spdResult.Sheets[0].Rows.Count!=0)
    {
     for(int i=0;i<spdResult.Sheets[0].Rows.Count;i++)
     {
      spdResult.Sheets[0].Rows[i].BackColor=System.Drawing.Color.White;
     }
     int row=e.Row;
     spdResult.Sheets[0].Rows[row].BackColor=System.Drawing.Color.FromArgb(((System.Byte)(192)),((System.Byte)(255)), ((System.Byte)(255)));
    }
   }
  }

3 將Spread的單元格內容付值給一控件的Text

txtItemCD.Text = spdResult.Sheets[0].Cells[row,count].Text;

4 給Spread的指定單元格付值。

spdResult.Sheets[0].Cells[row,count].Text = txtItemCD.Text;

5 通過上下光標鍵改變選中行顏色

private void spdResult_LeaveCell(object sender, FarPoint.Win.Spread.LeaveCellEventArgs e)
  {
   //首先檢查spread行數是否為0
   if(spdResult.Sheets[0].Rows.Count==0)
   {
    return;
   }
   else
   {
    for(int i=0;i<spdResult.Sheets[0].Rows.Count;i++)
    {
     spdResult.Sheets[0].Rows[i].BackColor=System.Drawing.Color.White;
    } 
    int row=e.NewRow;
    spdResult.Sheets[0].Rows[row].BackColor=System.Drawing.Color.FromArgb(((System.Byte)(192)),((System.Byte)(255)), ((System.Byte)(255))); 
   }
  }

6 下拉列表加載數據（ComBobox） 
・ 列表追加（適合於數據量少的情況）

FarPoint.Win.Spread.CellType.ComboBoxCellType cb4 = newFarPoint.Win.Spread.CellType.ComboBoxCellType();
   cb4.ListWidth = 96;
   cb4.Editable = true;
   cb4.MaxDrop = 10;
   cb4.MaxLength = 1;
   string[] priceTagList = new string[]{" 0 無"," 1 有"};
   cb4.Items = priceTagList;
   this.spdSetList.ActiveSheet.Columns[4].CellType = cb4;

・ 從數據庫追加

FarPoint.Win.Spread.CellType.ComboBoxCellType cb12 = newFarPoint.Win.Spread.CellType.ComboBoxCellType();
   cb12.ListWidth = 150;
   cb12.Editable = true;
   cb12.MaxDrop = 10;
   cb12.MaxLength = 8;

//dsEmployee：數據集Dataset,已經加載好數據的Dataset
   string[] employeeList = DataSetToArray(dsEmployee, 8);
   cb12.Items = employeeList;
   this.spdSetList.ActiveSheet.Columns[12].CellType = cb12;

private string[] DataSetToArray(DataSet ds, int BlankNum)
  {
   int i = 0;
   int NumLength = 0;
   string[] returnArray = new string[ds.Tables[0].Rows.Count];

   DataRow foundRows = ds.Tables[0].Rows[ds.Tables[0].Rows.Count -1];
   NumLength = foundRows[0].ToString().Length;

   foreach(DataRow dr in ds.Tables[0].Rows)
   {
    returnArray[i] = dr[0].ToString().PadLeft(BlankNum, ' ') + " " + dr[1].ToString();
    i++;
   }
   return returnArray;
  }

7 Focus移動（跨列）

public frmProdSetDetail()
  {
   InitializeComponent();
   IsMod = flag;

   FarPoint.Win.Spread.InputMap im;
   im = spdResult.GetInputMap(InputMapMode.WhenFocused);
   im.Put(new Keystroke(Keys.Enter,Keys.None),SpreadActions.MoveToNextColumnWrap);
   im.Put(new Keystroke(Keys.Tab,Keys.None),SpreadActions.MoveToNextColumnWrap);

   im = spdResult.GetInputMap(InputMapMode.WhenAncestorOfFocused);
   im.Put(new Keystroke(Keys.Enter,Keys.None),SpreadActions.MoveToNextColumnWrap);
   im.Put(new Keystroke(Keys.Tab,Keys.None),SpreadActions.MoveToNextColumnWrap);
  }

指定單元格獲得焦點      

this.fpSpread1.ActiveSheet.SetActiveCell(row，column);

8 事件觸發順序                            

 _Enter    _EnterCell      _EditModeOn      _EditChange      _EditModeOff      _LeaveCell

9 用隱藏列保存原始數據  

10 設定列類型

private void SpreadSetting()
  {
   string[] ProductHandleTypeList = new string[]{" ","1 販売/仕入","2 販売","3 仕入"};
  
   FarPoint.Win.Spread.CellType.ComboBoxCellType cb3 = newFarPoint.Win.Spread.CellType.ComboBoxCellType();
   cb3.ListWidth = 100;
   cb3.Editable = true;
   cb3.MaxDrop = 5;
   cb3.MaxLength = 1;
   cb3.Items = ProductHandleTypeList;

   this.spdResult.ActiveSheet.Columns[5].CellType = cb3;
 
   //設置一般數據型

   nmbrcell.LeadingZero = FarPoint.Win.Spread.CellType.LeadingZero.UseRegional;
   nmbrcell.MaximumValue = 9999;
   nmbrcell.MinimumValue = 1;
   this.spdResult.ActiveSheet.Columns[13].CellType = nmbrcell;

   //設置JAN

   FarPoint.Win.Spread.CellType.NumberCellType nmbrcellJan = newFarPoint.Win.Spread.CellType.NumberCellType();
   nmbrcellJan.ShowSeparator = false;

   this.spdResult.ActiveSheet.Columns[20].CellType = numberCellType1;

   //%數的設定

   FarPoint.Win.Spread.CellType.PercentCellType prctcell = newFarPoint.Win.Spread.CellType.PercentCellType(); 
   prctcell.PercentSign = "%";
   this.spdResult.ActiveSheet.Columns[33].CellType = prctcell;
   
   //日期的設定

   FarPoint.Win.Spread.CellType.DateTimeCellType datecell = newFarPoint.Win.Spread.CellType.DateTimeCellType(); 
   datecell.MaximumDate = new System.DateTime(2050, 12, 31, 0, 0, 0, 0);
   datecell.MinimumDate = new System.DateTime(2001, 1, 1, 0, 0, 0, 0);

   this.spdResult.ActiveSheet.Columns[27,30].CellType = datecell;
 }
