--------------------------------------------------------------------
Spread基本知识(一)
--------------------------------------------------------------------
1 取得当前行号、列号。int row=e.Row;
int count=e.Count;
或者:
int rowindex = fpSpread1.ActiveSheet.ActiveRowIndex;
int columnindex = fpSpread1.ActiveSheet.ActiveColumnIndex;
2 单击一行变颜色。
private void spdResult_CellClick(object sender, FarPoint.Win.Spread.CellClickEventArgs e)
{
//单击Spread列头时,什么也不处理
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 将Spread的单元格内容付值给一控件的Text
txtItemCD.Text = spdResult.Sheets[0].Cells[row,count].Text;
4 给Spread的指定单元格付值。
spdResult.Sheets[0].Cells[row,count].Text = txtItemCD.Text;
5 通过上下光标键改变选中行颜色
private void spdResult_LeaveCell(object sender, FarPoint.Win.Spread.LeaveCellEventArgs e)
{
//首先检查spread行数是否为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 下拉列表加载数据(ComBobox)
列表追加(适合于数据量少的情况)
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 无"," 1 有"};
cb4.Items = priceTagList;
this.spdSetList.ActiveSheet.Columns[4].CellType = cb4;
从数据库追加
FarPoint.Win.Spread.CellType.ComboBoxCellType cb12 = newFarPoint.Win.Spread.CellType.ComboBoxCellType();
cb12.ListWidth = 150;
cb12.Editable = true;
cb12.MaxDrop = 10;
cb12.MaxLength = 8;
//dsEmployee:数据集Dataset,已经加载好数据的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移动(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);
}
指定单元格获得焦点
this.fpSpread1.ActiveSheet.SetActiveCell(row,column);
8 事件触发顺序
_Enter _EnterCell _EditModeOn _EditChange _EditModeOff _LeaveCell
9 用隐藏列保存原始数据
10 设定列类型
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;
//设置一般数据型
FarPoint.Win.Spread.CellType.NumberCellType nmbrcell = newFarPoint.Win.Spread.CellType.NumberCellType();
nmbrcell.ShowSeparator = false;
nmbrcell.DecimalPlaces = 0;
nmbrcell.LeadingZero = FarPoint.Win.Spread.CellType.LeadingZero.UseRegional;
nmbrcell.MaximumValue = 9999;
nmbrcell.MinimumValue = 1;
this.spdResult.ActiveSheet.Columns[13].CellType = nmbrcell;
//设置JAN
FarPoint.Win.Spread.CellType.NumberCellType nmbrcellJan = newFarPoint.Win.Spread.CellType.NumberCellType();
nmbrcellJan.ShowSeparator = false;
nmbrcellJan.DecimalPlaces = 0;
nmbrcellJan.LeadingZero = FarPoint.Win.Spread.CellType.LeadingZero.UseRegional;
nmbrcellJan.MaximumValue = 9999999999999;
nmbrcellJan.MinimumValue = 0;
this.fpSpread1.ActiveSheet.Columns[0].CellType = nmbrcellJan;
this.fpSpread1.ActiveSheet.Columns[0].HorizontalAlignment =FarPoint.Win.Spread.CellHorizontalAlignment.Left;
//
FarPoint.Win.Spread.CellType.NumberCellType numberCellType1 = newFarPoint.Win.Spread.CellType.NumberCellType();
numberCellType1.ShowSeparator = true;
numberCellType1.DecimalPlaces = 0;
numberCellType1.LeadingZero = FarPoint.Win.Spread.CellType.LeadingZero.UseRegional;
numberCellType1.MaximumValue = 99999999;
numberCellType1.MinimumValue = 0;
this.spdResult.ActiveSheet.Columns[20].CellType = numberCellType1;
//%数的设定
FarPoint.Win.Spread.CellType.PercentCellType prctcell = newFarPoint.Win.Spread.CellType.PercentCellType();
prctcell.PercentSign = "%";
this.spdResult.ActiveSheet.Columns[33].CellType = prctcell;
//日期的设定
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;
}
11 列、单元格锁定
//锁定
this.fpSpread1.ActiveSheet.Columns[0,4].Locked = true;//锁定列范围
this.fpSpread1.ActiveSheet.Columns[0].Locked = true;//锁定单列
//解锁
this.fpSpread1.ActiveSheet.Columns[0,4].Locked = false;//解锁列范围
this.fpSpread1.ActiveSheet.Columns[0].Locked = false;
如通过下面代码我们可以准确的判断单元格是否处于锁定状态: StyleInfo csi = new StyleInfo(); StyleInfo dsi = new StyleInfo(); fpSpread1.ActiveSheet.Models.Style.GetCompositeInfo(fpSpread1.ActiveSheet.ActiveRowIndex, fpSpread1.ActiveSheet.ActiveColumnIndex, -1, csi); fpSpread1.ActiveSheet.Models.Style.GetDirectInfo(fpSpread1.ActiveSheet.ActiveRowIndex, fpSpread1.ActiveSheet.ActiveColumnIndex, dsi);
12 Spread追加行、列
//追加行
int rowindex = this.fpSpread1.ActiveSheet.Rows.Count;
this.fpSpread1.ActiveSheet.Rows.Add(rowindex,1);
//追加列
int columnindex = this.fpSpread1.ActiveSheet.Columns.Count;
this.fpSpread1.ActiveSheet.Columns.Add(columnindex,1);
13 行、列删除
//删除行
this.fpSpread1.ActiveSheet.Rows.Remove(startindex,count);
//追加列
this.fpSpread1.ActiveSheet.Columns.Remove(startindex,count);
14 button事件
private void spdSetList_ButtonClicked(object sender, FarPoint.Win.Spread.EditorNotifyEventArgs e)
{
int rowCount = e.Row;
int columnCount = e.Column;
if (e.Column == 16)
{
if (message.ShowMessage("ConfirmDelete", "選択したライン") == DialogResult.Yes)
{
string DeleteTag = this.spdSetList.ActiveSheet.Cells[rowCount, columnCount+1].Text.Trim();
if (DeleteTag == "0" || DeleteTag == "2")
{
this.spdSetList.ActiveSheet.Cells[rowCount, columnCount+1].Text = "3";
this.spdSetList.ActiveSheet.Cells[rowCount,columnCount+1].BackColor = clrWater;
this.spdSetList.ActiveSheet.Rows[rowCount].Visible = false;
}
else if (DeleteTag == "1")
{
this.spdSetList.ActiveSheet.Rows[rowCount].Remove();
}
}
}
}

Spread 加载、插入、修改数据库-转载
---------------------------------------------------------------------
以下是代码(只有三个按钮的代码,其他代码略)://修改
private void btnUpdate_Click(object sender, System.EventArgs e)
{
//首先判断spread行数大于0
if(fpSpread1.ActiveSheet.Rows.Count > 0)
{
dbproc.Open();//打开数据库,这是我自己的连接数据库类,请替换你自己的连接数据库部分
//循环更新
for(int i=0;i<fpSpread1.ActiveSheet.Rows.Count;i++)
{
string update = "update areas ";
update += " set areaName = '" + fpSpread1.ActiveSheet.Cells[i,2].Text.ToString().Trim() + "'";
update += " where areaCD = " + fpSpread1.ActiveSheet.Cells[i,0].Text.ToString().Trim();
dbproc.Execute(update);//更新数据库,这是我自己的更新数据库类,请替换你自己的连接数据库部分
}
dbproc.Close();//关闭数据库,这是我自己的关闭数据库类,请替换你自己的连接数据库部分
}
}
//加载数据
private void btnLoad_Click(object sender, System.EventArgs e)
{
dbproc.Open();//打开数据库,这是我自己的连接数据库类,请替换你自己的连接数据库部分
string select = "select * from areas where areaCD < 100";
//定义一个Dataset
DataSet ds= dbproc.OpenDataSet(select);//这是我自己的获取数据类,请替换你自己的获取数据库部分
//绑定数据
fpSpread1.ActiveSheet.DataSource = ds.Tables[0].DefaultView;
dbproc.Close();//关闭数据库,这是我自己的关闭数据库类,请替换你自己的连接数据库部分
}
//插入
private void btnInsert_Click(object sender, System.EventArgs e)
{
if(fpSpread1.ActiveSheet.Rows.Count > 0)
{
dbproc.Open();//打开数据库,这是我自己的连接数据库类,请替换你自己的连接数据库部分
for(int i=0;i<fpSpread1.ActiveSheet.Rows.Count;i++)
{
string insert = "insert into areas ..";(具体sql语句略)
dbproc.Execute(insert);//这是我自己的插入数据类,请替换你自己的插入数据库部分
}
dbproc.Close();//关闭数据库,这是我自己的关闭数据库类,请替换你自己的连接数据库部分
}
}

解决使用spread时快捷键无反应的情况
-----------------------------------------------------------------------
如果我的画面中有快捷键,比如说“F1”、“F2”、“F3”等等,当你的焦点在spread里边时,你会发现你定义的那些快捷键有时候不反应,原因是焦点陷入spread里面,导致画面捕捉不到快捷键。FarPoint.Win.Spread.InputMap im;
//spdResult是你画面中定义的spread的名字。
//WhenFocused:焦点离开时
im = spdResult.GetInputMap(InputMapMode.WhenFocused);
//按回车键和TAB时,焦点移动到下一个单元格
im.Put(new Keystroke(Keys.Enter,Keys.None),SpreadActions.MoveToNextColumnWrap);
im.Put(new Keystroke(Keys.Tab,Keys.None),SpreadActions.MoveToNextColumnWrap);
//按→、↓、←、↑时,焦点移动
im.Put(new Keystroke(Keys.Left,Keys.None),SpreadActions.MoveToPreviousColumn);
im.Put(new Keystroke(Keys.Right,Keys.None),SpreadActions.MoveToNextColumn);
//使快捷键有效
im.Put(new Keystroke(Keys.F1,Keys.None),SpreadActions.None);
im.Put(new Keystroke(Keys.F2,Keys.None),SpreadActions.None);
im.Put(new Keystroke(Keys.F3,Keys.None),SpreadActions.None);
im.Put(new Keystroke(Keys.F8,Keys.None),SpreadActions.None);
im.Put(new Keystroke(Keys.F10,Keys.None),SpreadActions.None);
im.Put(new Keystroke(Keys.F12,Keys.None),SpreadActions.None);
//WhenAncestorOfFocused:得到焦点时
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);
