dbgrid refresh delay

[jahlxx]

Hi.

 

I've a unidbgrid, and in my sample, when click in the first column I do this;

 

qt.edit;

qt.fieldbyname('sel').asboolean .= not qt.fieldbyname('sel').asboolean;

qt.post;

 

 

everything is OK, but every time I do thois, the message "Loading data ..." appears, and is a delay.

 

is not many time, but this is a simple edit of a column and soluld be inmediate, but there is a delay.

 

I use unidac components to access database.

 

is this behaviour ok?

Hi,

 

Maybe you need to change the logic?

 

Can you explain, for what purpose do you need it?

[jahlxx]

check / uncheck rows

 

in vcl apps, is inmediate. after post the control returns to user inmediately.

 

the dataset is localupdate.

is this behaviour ok?

Actually it is a normal behavior.

Does it actually load data?

Do you click on a checkbox?

[jahlxx]

You can use AutoPost option of check columns. You don't need to manually change and post data.

[jahlxx]

ok. testing but, how check / uncheck?

 

I click the field, but does nothing.

Hi,

 

Can you make a testcase with screenshots, showing where the problem is ?

[jahlxx]

Is dificult.

 

How autopost works?;

 

I set the autopost of the column to true, but when click, the value don't change..

 

I am missing something, but don't know what-

Please see the related demo.

Have you seen the demo examples - grid with checkboxes?

[Sherzod]

Column -> CheckBoxField -> AutoPost = True

[jahlxx]

ok. problem detected.

 

when the grid has summary, allways has the behaviour I commented before.

 

even when the summary procedure (calctotals) does nothing.

[Farshad Mohajeri]

Yes. It happens because unigui can not know if the changed row affects the summary data or not. That's why it needs to refresh the grid.
