Dbgrideh record statistics

Dbgrideh is used to set fixed columns for statistics on the number of records, average number, and sum.

 

Dbgrideh1.footerrowcount: = 1; // use one line at the bottom of dbgrideh to display information.
Dbgrideh1.sumlist. Active: = true;
Dbgrideh1.columns [0]. footer. valuetype: = fvtstatictext; // display the "number of current records:" In the first column

Dbgrideh1.columns [0]. footer. Value: = 'current number of records :';
Dbgrideh1.columns [1]. footer. valuetype: = fvtcount; {valuetype includes fvtavg, fvtcount, fvtfilevalue, fvtnon, fvtstaictext, and fvtsum. You can change this value to select the information you need to collect}
