Hello,

Sorry, the question is not clear.

Hello!

I need the user to reach the end of a grid by clicking on tab to insert a new line, automatically.
I need this line to be discarded when the user hits ESC or hits the up arrow
I need the user when entering a unidbgrid to automatically insert a blank line.

All these behaviors are common in any grid in Delphi, but I'm having a hard time implementing them in Unigui.

There are codes that deal with this in the forum like the one below, but they cause other problems and instabilities. How do I resolve this? Shouldn't these needs above be standard in Unigui?

procedure TMainForm.UniDBGrid1KeyDown(Sender: TObject; var Key: Word;
  Shift: TShiftState);
var
  isLastRecord: Boolean;
begin
  isLastRecord := (Sender as TUniDBGrid).DataSource.DataSet.RecNo = (Sender as TUniDBGrid).DataSource.DataSet.RecordCount;
  
  if (Key = VK_TAB)and(isLastRecord)and(TUniExDBGrid(Sender).CurrCol=(Sender as TUniDBGrid).Columns.Count-1) then
  begin
    // your logic
    (Sender as TUniDBGrid).DataSource.DataSet.Append;
  end;
end;

I prepared an example project, in addition to the "grid in dirt state" and "recno mismatch" error messages, focus is lost if all grids are active.

Is something so simple in VCL so impossible in Unigui?

I personally would not use grid to insert data.

[heronim]

Does this mean unigrid was not made to include data?

Isso significa que a Unigrid não foi feita para incluir dados?

As "I" said, I don't like it.
And if you look at web systems,
this is not common.

Synchronous  and  asynchronous.

A lot of asynchronous with web app.

So my statement is correct, Unidbgrid is not for data inclusion

I will try to check your testcase.

Not for displaying data you mean? If so, then your statement is incorrect.

Hi, 
in "intensive" systems, user must insert data directly into grid cells.
Even if in web world this is a "strange" manner, we need direct input (with automatic append) on Dbgrids for porting Desktop applications, and this make differences with other competitor's systems because it's faster and more ergonomic.
Thanks to all

Will this issue be addressed?

The worst response for a customer isn't a negative, it's a vacuum.

I also need to append record sequentially in Dbgrid, but it seems that nobody have this need.
It's too difficult  to implement a working "VCL" datagrid input?
I remember that a "light" grid for fast data input was planned (like a cached update on client). There are news on this?
Thanks
