Google translate says:

 

I'm not English, good-hearted people to help translate yourself! Thank =

you!

 

Objective: According to the value of a particular column in the table =

identifies the specific use of the color line.

Demos in DBLookup example with a change in the UniDBGrid the =

OnDrawColumnCell event add the following code:

procedure TMainForm.UniDBGrid1DrawColumnCell (Sender: TObject; ACol,

ARow: Integer; var Value: string; Column: TUniDBGridColumn;

Attribs: TUniCellAttribs);

begin

if Column.FieldName =3D 'OrderNo' then

if Column.Field.Value <1010 then

Attribs.Color: =3D clRed;

end;

 

VCL mode, the corresponding speed was okay, but the WEB mode is very =

bad.

If you write something like this even worse. However, I hope to identify =

the positive line of data.

procedure TMainForm.UniDBGrid1DrawColumnCell (Sender: TObject; ACol,

ARow: Integer; var Value: string; Column: TUniDBGridColumn;

Attribs: TUniCellAttribs);

begin

if UniMainModule.ClientDataSet1.FieldByName ('OrderNo'). Value <1010 =

then

Attribs.Color: =3D clRed;

end;

 

My response:

 

Custom cell rendering can reduce performance. You must use it in Paged =

mode where number of rows are limited.

In my PC which is a low-end dual-core performance is acceptable. What is =

your PC configuration?

If you have lots of columns and rows with colored attributes then it is =

possible, but again 5 seconds is too much.
