问题描述
网上的代码，下下来学习，但是当单元格内内容超出单元格后，出现截取，怎么做才能使其换行，而不是截取？#region绘制过程//*****这段代码确实太长了，应该用重构的手法进行处理，不过，我这里主要是让大家从头到尾的顺利的看下去//*****在下一个版本的源代码中我会整理，大家也可以试一试。privateboolDraw(Graphicsg){boolblnHasMorePage=false;//是否还有下一页标记if(this._body.Rows<0){thrownewException("打印主要网格不能为空，请用Body设置！");}Printerprinter=newPrinter();printer.Graphics=g;printer.PrintDocument=this.mPrintDocument;printer.Sewing=this.Sewing;//初起打印起点坐标及打印区域的宽Y=printer.PrinterMargins.Top;X=printer.PrinterMargins.Left;Width=printer.PrinterMargins.Width;#region画打印区域及装订线if(IsPrinterMargins){printer.DrawPrinterMargins();}if(IsSewingLine&&_sewing.Margin>0){//对象的线长小于0则自动设置if(this._sewing.LineLen<0){if(this._sewing.SewingDirection==SewingDirectionFlag.Left){this._sewing.LineLen=printer.PageHeight;}elseif(this._sewing.SewingDirection==SewingDirectionFlag.Top){this._sewing.LineLen=printer.PageWidth;}}printer.Sewing=this._sewing;printer.DrawSewing();}#endregion//正标题每页必重复打印，无需判断if(_title!=null){OutObject(_title);}if(_caption!=null&&(mCurrentPageIndex==1||_caption.IsDrawAllPage)){if(_caption!=null){if(_title!=null){_caption.MoveY=this._title.Height+5;}OutObject(_caption);}}if(_title!=null||_caption!=null){Y+=20;//标题与下面有一定距离}if(_top!=null&&(mCurrentPageIndex==1||_top.IsDrawAllPage)){OutObject(_top);}if(_header!=null&&(mCurrentPageIndex==1||_header.IsDrawAllPage)){OutObject(_header);}if(_title!=null||_caption!=null||_top.IsDrawAllPage||_header.IsDrawAllPage){Y+=5;//网格与页头距离}if(_multiHeader!=null&&(mCurrentPageIndex==1||_multiHeader.IsDrawAllPage)){OutObject(_multiHeader);}#region主体数据网格//计算有效高度，便于分页floatvalidHeight=printer.PrinterMargins.Height-(Y-printer.PrinterMargins.Top);if(_footer!=null&&_footer.IsDrawAllPage){validHeight-=this._footer.Height;}if(_bottom!=null&&_bottom.IsDrawAllPage){validHeight-=this._bottom.Height;}if(validHeight<0){thrownewException("预留给打印主要网格的空间太小，请适当调整！");}//有效高度中当前页行数intmRowsInCurPage=0;mRowsInCurPage=(int)(validHeight/(float)(this._body.RowHeight));//如果指定每页行数，则以其为主if(this.RowsPerPage>0&&this.RowsPerPage<mRowsInCurPage){mRowsInCurPage=this.RowsPerPage;}if(this.IsSubTotalPerPage){mRowsInCurPage--;}//************以Body为主************string[,]mArrGridText;//保留当前页文本，用于页小计GoldPrinter.Bodymbody;//如果指定每页行数，则以其为主if(this.RowsPerPage>0&&this.RowsPerPage<mRowsInCurPage){mbody=newBody(mRowsInCurPage,this._body.Cols);}else{//否则自适应if(mRowsInCurPage>(this._body.Rows-this.mCurrentRowIndex)){mRowsInCurPage=this._body.Rows-this.mCurrentRowIndex;}mbody=newBody(mRowsInCurPage,this._body.Cols);}mbody.ColsAlignString=this._body.ColsAlignString;//存当前页的二维文本mArrGridText=newstring[mRowsInCurPage,this._body.Cols];for(inti=0;i<mRowsInCurPage&&mCurrentRowIndex<this._body.Rows;i++){for(intj=0;j<this._body.Cols;j++){mArrGridText[i,j]=this._body.GetText(mCurrentRowIndex,j);}mCurrentRowIndex++;}mbody.GridText=mArrGridText;OutObject(mbody);//判断是否要分页，只要数据网格行数据大于数据网格行指针，则还有下一页if(mCurrentRowIndex<this._body.Rows){blnHasMorePage=true;}#region打印每页小计，只需要将当前数组用循环累计就OK了，这段程序应专门重构为一个函数，读者可以自己试一试if(_isSubTotalPerPage&&_subTotalCol!=""){try{GoldPrinter.MultiHeadermhSubTotal=newMultiHeader(1,this._body.Cols);mhSubTotal.Graphics=g;mhSubTotal.PrintDocument=this.mPrintDocument;mhSubTotal.Sewing=this._sewing;mhSubTotal.RectangleF=newRectangleF(X,Y,Width,mhSubTotal.Height);//循环//....mhSubTotal.SetText(0,0,"本页小计");mhSubTotal.SetText(0,1,"本页小计");string[]marrSubTotalCol=this._subTotalCol.Split(';');DoublemdblSubTotal=0f;intmintCol=0;for(inti=0;i<marrSubTotalCol.Length;i++){mintCol=int.Parse(marrSubTotalCol[i].Substring(0,1));for(intj=0;j<mArrGridText.GetLength(0);j++){mdblSubTotal+=Double.Parse(mArrGridText[j,mintCol]);}mhSubTotal.SetText(0,mintCol,mdblSubTotal.ToString());}mhSubTotal.Draw();Y+=mhSubTotal.Height;}catch(Exceptione){}}#endregion#endregionY+=5;//网格与页底距离//打印页脚与最底if(_footer!=null){if(blnHasMorePage==false||_footer.IsDrawAllPage){//这里不再做判断了，读者自己对照Body的处理方法去试验，以加深理解，实际上应是注释的部分OutObject(_footer);/*if(_footer.IsDrawAllPage){OutObject(_footer);}else{//与Body同样的处理}*/}}if(_bottom!=null){if(blnHasMorePage==false||_bottom.IsDrawAllPage){if(_bottom.IsDrawAllPage){OutObject(_bottom);}else{//计算有效高度validHeight=printer.PrinterMargins.Height-(Y-printer.PrinterMargins.Top);if(validHeight<_bottom.Height){blnHasMorePage=true;}else{OutObject(_bottom);}}}}//画边框DrawBorder(g,this._multiHeader,mbody);mbody=null;returnblnHasMorePage;}#endregionprivatevoidDrawBorder(Graphicsg,MultiHeadermultiHeader,Bodybody){//网格边框矩阵RectangleFmrecGridBorder;floatx,y,width,height;width=body.RectangleF.Width;height=body.RectangleF.Height;if(multiHeader!=null){x=multiHeader.RectangleF.X;y=multiHeader.RectangleF.Y;height+=multiHeader.RectangleF.Height;}else{x=body.RectangleF.X;y=body.RectangleF.Y;}if(this.IsSubTotalPerPage){GoldPrinter.MultiHeaderm=newMultiHeader(1,1);height+=m.RowHeight;m=null;}mrecGridBorder=newRectangleF(x,y,width,height);Penpen=newPen(Color.Black,1);GoldPrinter.DrawRectangledr=newDrawRectangle();dr.Graphics=g;dr.RectangleF=mrecGridBorder;dr.Pen=pen;switch(GridBorder){caseGridBorderFlag.Single:dr.Draw();break;caseGridBord
