在dbgrideh中允许选择多行,如何知道哪些行被选中?
是个BOOKMARK类型的属性。
SelectedRows: TBookmarkList
procedure TForm1.Button1Click(Sender: TObject);
var
i, j: Integer;
s: string;
begin
if DBGrid1.SelectedRows.Count>0 then
with DBGrid1.DataSource.DataSet do
for i:=0 to DBGrid1.SelectedRows.Count-1 do
begin
GotoBookmark(pointer(DBGrid1.SelectedRows.Items[i]));
for j := 0 to FieldCount-1 do
begin
if (j>0) then s:=s+‘, ‘;
s:=s+Fields[j].AsString;
end;
Listbox1.Items.Add(s);
s:= ‘‘;
end;
end;
dbgrideh 上选择多行之后,要求把所选择的记录全部添加入SQL数据库的一个固定表中。
dbgrideh.selectedrows记载了所有被选择行的bookmark;利用SelectedRows和GotoBookmark完成。代码如下:
procedure TForm1.Button1Click(Sender: TObject);
var
i, j: Integer;
s: string;
begin
if DBGrid1.SelectedRows.Count>0 then
with DBGrid1.DataSource.DataSet do
for i:=0 to DBGrid1.SelectedRows.Count-1 do
begin
GotoBookmark(pointer(DBGrid1.SelectedRows.Items[i]));
for j := 0 to FieldCount-1 do
begin
if (j>0) then s:=s+‘, ‘;
s:=s+Fields[j].AsString;
end;
Listbox1.Items.Add(s);
s:= ‘‘;
end;
end;
