Spread控制元件基礎知識（基本常用屬性事件等）
-----------------------基本用法
//取當前行號、列號
int row=e.Row;
int count=e.Count;
或者：
int rowindex = fpSpread1.ActiveSheet.ActiveRowIndex;
int columnindex = fpSpread1.ActiveSheet.ActiveColumnIndex;
//單機行改變該行顏色
private void spdResult_CellClick(object sender, FarPoint.Win.Spread.CellClickEventArgs e)
{
//單擊Spread列頭時，什麼也不處理
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)));
}
}
}
//將Spread的單元格內容付值給一控制元件的Text，給指定單元格賦值
txtItemCD.Text = spdResult.Sheets[0].Cells[row,count].Text;
spdResult.Sheets[0].Cells[row,count].Text = txtItemCD.Text;
//通過游標改變行選中顏色
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)));
}
}
//下拉列表載入資料
寫死資料來源
FarPoint.Win.Spread.CellType.ComboBoxCellType cb4 = new FarPoint.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;
資料庫獲取
FarPoint.Win.Spread.CellType.ComboBoxCellType cb12 = new FarPoint.Win.Spread.CellType.ComboBoxCellType();
cb12.ListWidth = 150;
cb12.Editable = true;
cb12.MaxDrop = 10;
cb12.MaxLength = 8;
//dsEmployee：資料集Dataset,已經載入好資料的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;
}
//焦點移動（跨列）
public frmProdSetDetail()
{
InitializeComponent();
IsMod = flag;
FarPoint.Win.Spread.InputMap im;
im = spdResult.GetInputMap(InputMapMode.WhenFocused);

}
給某列指定焦點：this.fpSpread1.ActiveSheet.SetActiveCell(row，column);

//追加、刪除行列
追加行
