UniStringGrid validating cells

Hi everyone,

 

I'm trying to validate a UniStringGrid's Cell content with a number.

 

Would be great to have OnKeyPress or OnKeyDown.

 

Some plans to add this in next versions ?

 

There is another workaround to do this?

 

Thanks.

You want to validate cells in OnKeyDown event?

 

 

Hi, Farshad,

 

Well.......yes, too newbiest my request? sorry, jeje.

 

I would like to control in a UniStringGrid cell only numbers, like in Delphi: if Key in ['0','1','2','3',.....] but this is controled by OnKeyDown and OnKeyPress of the SG, right ?

 

Thanks by your reply.

Hi Farshad.

 

I did it like this, in case somebody needs it too. (Someone as newbie as me).

 

Inside the DrawCell of the UniStringGrid:

 

if (ACol = 4) and (ARow > 0) then

begin

Value := IntToStr(StrToIntDef(Value,0));

end;

 

 

You can use OnDrawCellEvent for this.

Hi,

 

I'm still working with UniStringGrid, for some reasons not a UniDBGrid:

 

I used OnDrawCell for coloring some columns (USG_drawed_col.png) but it takes 6 secs to navigate to another record.

If I remove coloring columns in OnDrawCell, this takes less than a sec, just a blink of an eye.(USG_not_drawed_col.png)

 

Would be good have a nice presentation with a good speed on this.

Can be this fixed, please?

 

Regards,

It can be fixed as soon as I can reproduce it.

 

In your pics there are only 3 records in grid. It is very unlikely to take 6 secs to move from a row to another. Can you reproduce same thing with a grid attached to a local TClientDateset?

 

PS: Is grid in above pic a DBGrid or a StringGrid?

I have this config:

 

Postgres 9 in localhost

ZeosDBO 7 using a ZTable dataset for Master table.

I fill in the detail data from another ZTable to the UniStringGrid by code.

 

The filling time is not the problem, neither pass from 1 row to another row, time spend is when I scroll the UniDBNavigator to next or prior master record.

UniDBNavigator simply calls Next on Dataset. Since you manually fill StringGrid I need to see your code.

 

It would be better if you send a test case created with Clientdataset.

This is my part of code to fill in the UniStringGrid:

 

while not(table.Eof) do

begin

for j:=Low(fields) to High(fields) do

begin

sg.Cells[j,i] := table.Fields[fields[j]].AsString;

end;

i:=i+1;

if table.RecNo < table.RecordCount then

sg.RowCount:=sg.RowCount+1;

table.Next;

end;

 

I can make a test case, would you guide me with this? please?

I've seen the FishFacts demo with a ClientDataset, but how can I create two tables in cds format? I don't use paradox.

           if table.RecNo < table.RecordCount then
             sg.RowCount:=sg.RowCount+1;
           table.Next;
         end;

 

UniStringGrid is not optimized for sending big number of rows in a loop. It is in todo list.

 

I recommend using uniDBGrid anyway.
