Xtrareport allows you to specify the number of records and fill in blank rows.

In the detail event:

Int I = 0;
Private void onbeforeprint (Object sender, system. Drawing. Printing. printeventargs e ){
// Control the number of items displayed on each page
If (I! = 0 & I % 8 = 0) // 8 entries per page
{
Detail. pagebreak = devexpress. xtrareports. UI. pagebreak. beforeband;
}
Else
{
Detail. pagebreak = devexpress. xtrareports. UI. pagebreak. None;
}
I ++;
}

In the table event:

Private void onbeforeprint (Object sender, system. Drawing. Printing. printeventargs e ){
//////////////////////////////////////// ///// // Replace the dataset "storagebillmatitem"
If (I = (system. Data. dataset) (xtrareport1.datasource). Tables ["storagebillmatitem"]. Rows. Count)
{
Xrtable table = xrtable2; // template detail band xrtable
Int iheight = table. Rows [Table. Rows. Count-1]. height;

Int spacerowcount = 8-(I) % 8;
Xrtablerow [] xrrow = new xrtablerow [spacerowcount];

For (int K = 0; k <spacerowcount; k ++)
{
Xrrow [k] = new xrtablerow ();
Xrrow [K]. size = new size (table. Width, iheight );
Xrrow [K]. Location = new point (table. Location. X, K * iheight );
Xrrow [K]. Borders = (devexpress. xtraprinting. borderside) (borderside. Left | borderside. Right) | borderside. Top );

// Createcell
