Hello Ronald,

Angel's suggestion would work, but by executing that through the grid you'll end up triggering all kinds of events that you're not intending here. I would suggest actually deleting from your underlying data source, and that change will be reflected in your UltraGrid.

Please let me know if I can further assist you.

Hi,

Primero Seleccionas todo el rango de filas de la grilla

this.Ultragrid1.Selected.Rows.AddRange((UltraGridRow[])this.Ultragrid1.Rows.All);

para despues borrar todas las filas de la grilla y asi quedaria totalmente limpio

this.dgvUltragrid1.DeleteSelectedRows(false);
