Sorry, maybe this question is dumb, but i can't figure how to generate auto increment number for each row in Grid automatically.
Format:
1 data
2 data
3 data
etc
How to properly use function count()
Thanks a lot.

what database are you using - easiest way is to set the primary key to auto-increment in the database....

Damian thank you
I use MySQL database, but I have correctly set primary key auto-increment in the database. What I need is to generate on the fly counter for each row (Label control) in a row like
1,2,3..... not depending what actual ID primary key is
Thanks again

This can be done using a label and a counter. For example:
First put
$rowcounter = 0;
on top of your page
Then, in the grid's BeforeShowRow Event, increment the counter:
$rowcounter+=1;
And then set your counter label to the counter value:
$sender->lblCounter->SetValue($rowcounter);
Hope this helps,
Rob.

Thanks Rob
I tried this, but had problem because in my case it is "Editable Grid" from "Order Entry" Example Pack de CodeCharge and I have already Events in "Before Row Show".
Don't work

For the code to be entered, you have to create "Custom Code" on the BeforeShowRow event...
