How to add Column in run-time?

First add next code in uses section:

uses NxColumns, NxColumnClasses;

Then call Add method of Columns property. Add method require that you specify Column Class for new column (TNxTextColumn, TNxNumberColumn, TNxDateColumn...). Next line will add one TNxTextColumn:

NextGrid1.Columns.Add(TNxTextColumn);

NextGrid1->Columns->Add(__classid(TNxTextColumn))

or we can add one TNxDateColumn:

NextGrid1.Columns.Add(TNxDateColumn);

NextGrid1->Columns->Add(__classid(TNxDateColumn))

Use same method for all Column types (TNxNumberColumn, TNxImageColumn...)

How to paint each second row in different color?

if not(csSelected in CellState) then
begin
  if ARow mod 2 = 0 then CellColor := $00F5FCFE;
end;

if(CellState.Contains(csSelected)) {
  if (ARow % 2 = 0) {
    CellColor := $00F5FCFE;
  }
};

How to format number when displaying cell?

0.00 			1234.00		-1234.00	0.50		0.00
#.##  			1234		-1234		.5	
#,##0.00		1,234.00	-1,234.00	0.50		0.00
#,##0.00;(#,##0.00)	1,234.00	(1,234.00)	0.50		0.00

How to get column with links?

Insert one TNxTextColumn, click on this column in editor and in Font property, set Style sub-property to fsUnderline, also set Font.Color to clBlue. Then set Cursor property to crHandPoint.

If you want to show system Hand Point cursor, instead of Delphi Hand Point cursor insert next code in OnCreate event of main form:

var
  C: HCURSOR;
begin
  C := LoadCursor(0, IDC_HAND);
  if C <> 0 then Screen.Cursors[crHandPoint] := C;
end;

Then, if you want to do something when user click on link you need to insert code in OnSelectCell event. In this event, simply check ACol and ARow parameter and do some action.

if ACol = 4 then
begin
  NextGrid1.DeleteRow(ARow);
end;
