XtraReports 报表记录不满一页时填补空行

Devexpress 版本：10.2.5

 

先看实现效果

当报表数据不满一页时，填补空行 

 

当报表数据超过一页时，最后一页填补空行

 

 

 代码： 

 

XtraReport rpt  =   new  XtraReport(); //  建立报表实例
rpt.FillEmptySpace  +=   new  BandEventHandler(rpt_FillEmptySpace); // 绑定填充空行的事件  

 

对应的事件代码：

 

 

void  rpt_FillEmptySpace( object  sender, BandEventArgs e)
{
    XRTable table  =  tableDetail; // Template Detail Band XRTable
     int  iheight  =  table.Rows[table.Rows.Count  -   1 ].Height;

    XRTable xrTable  =   new  XRTable();
    xrTable.Size  =   new  Size(table.Width, e.Band.Height  -   1 );
    xrTable.BorderWidth  =  table.BorderWidth;
    xrTable.Location  =  table.Location;
    xrTable.BackColor  =  table.BackColor;

     int  SpaceRowCount  =  e.Band.Height  /  iheight;

    XRTableRow[] xrRow  =   new  XRTableRow[SpaceRowCount];

     if  (SpaceRowCount  >   0 )
    {
         for  ( int  i  =   0 ; i  <  SpaceRowCount; i ++ )
        {
            xrRow[i]  =   new  XRTableRow();
            xrRow[i].Size  =   new  Size(table.Width, iheight);
            xrRow[i].Location  =   new  Point(table.Location.X, i  *  iheight);
            xrRow[i].Borders  =  (DevExpress.XtraPrinting.BorderSide)((BorderSide.Left  |  BorderSide.Right)  |  BorderSide.Bottom);
            xrRow[i].BorderWidth  =   1 ;
            xrRow[i].BorderColor  =  table.Rows[table.Rows.Count  -   1 ].BorderColor;
             // CreateCell
            XRTableRow row  =  table.Rows[table.Rows.Count  -   1 ];
            CreateCellArray(xrRow[i], row);
        }
        xrTable.Rows.AddRange(xrRow);
        e.Band.Controls.Add(xrTable);
    }
}
