Spread for ASP.NET 6.0中客户端删除是通过CommandBar上的删除按钮来实现的，默认状态下该操作一次只能删除一行数据，在实际需求中，我们往往需要一次删除多行数据。
CellType
CellType
this.FpSpread1.ActiveSheetView.Columns[0].CellType = new FarPoint.Web.Spread.CheckBoxCellType(); 复制代码2、重写“删除”按钮的默认行为（服务端）
protected override void Render(HtmlTextWriter writer)
{
WebControl delButton = FpSpread1.FindControl("Delete") as WebControl;
if (delButton != null)
{
delButton.Attributes.Add("onclick", "MultiDlete();return false;");
}
base.Render(writer);
}

-
<script language="javascript" type="text/javascript"> function MultiDlete() { var ss = FpSpread("FpSpread1"); if (ss != null) { ss.UpdatePostbackData(); ss.CallBack("MultiDlete"); } } </script> 复制代码4、删除用户选择的数据行
-
protected void FpSpread1_ButtonCommand(object sender, FarPoint.Web.Spread.SpreadCommandEventArgs e) { if (e.CommandName.Equals("MultiDlete")) { for (int r = FpSpread1.ActiveSheetView.RowCount - 1; r >= 0; r--) { var check = FpSpread1.ActiveSheetView.Cells[r, 0].Value; if (check != null && (Convert.ToInt32(check) == 1)) { FpSpread1.ActiveSheetView.Rows.Remove(r, 1); } } } } 复制代码第二种：删除用户选中的所有行
1、重写“删除”按钮的默认行为（服务端）
-
protected override void Render(HtmlTextWriter writer) { WebControl delButton = FpSpread1.FindControl("Delete") as WebControl; if (delButton != null) { delButton.Attributes.Add("onclick", "MultiDlete();return false;"); } base.Render(writer); } 复制代码2、重写“删除”按钮的默认行为（客服端）
-
<script language="javascript" type="text/javascript"> function MultiDlete() { var ss = FpSpread("FpSpread1"); if (ss != null) { ss.UpdatePostbackData(); ss.CallBack("MultiDlete"); ss.ClearSelection(); } } </script> 复制代码3、删除用户选择的数据行
protected void FpSpread1_ButtonCommand(object sender, FarPoint.Web.Spread.SpreadCommandEventArgs e)
{
if (e.CommandName.Equals("MultiDlete"))
{
CellRange[] cRanges = FpSpread1.ActiveSheetView.GetSelections();
for (int i = cRanges.Length -1; i >= 0; i--)
{
FpSpread1.ActiveSheetView.RemoveRows(cRanges[i].Row, cRanges[i].RowCount);
}
}
}
