I have a Delphi application using DevExpress cxGrid (which is connected to database).
I require to be able to copy-paste data from Excel into the grid.
Is this possible? If so, how to do it, which additional components do i need?
Check the format with Clipboard.HasFormat(CF_TEXT)
.
Extract the text with Clipboard.AsText
.
Split into rows with StringList.Text := Clipboard.AsText
. Each item in the string list is now a row from the clipboard.
Split each row into individual cells using a Split function:
function Split(const s: string; Separator: char): TStringDynArray;
var
i, ItemIndex: Integer;
len: Integer;
SeparatorCount: Integer;
Start: Integer;
begin
len := Length(s);
if len=0 then begin
Result := nil;
exit;
end;
SeparatorCount := 0;
for i := 1 to len do begin
if s[i]=Separator then begin
inc(SeparatorCount);
end;
end;
SetLength(Result, SeparatorCount+1);
ItemIndex := 0;
Start := 1;
for i := 1 to len do begin
if s[i]=Separator then begin
Result[ItemIndex] := Copy(s, Start, i-Start);
inc(ItemIndex);
Start := i+1;
end;
end;
Result[ItemIndex] := Copy(s, Start, len-Start+1);
end;
