Hi Gao Yixin,

Actually, We could not just add multiple rows in there. But based on your code, that is not exception error. That happens because when one row is added, the process has not finished yet. 

e.g if WebGrid is still doing one process and has not finished, try to call another FlyPostback request such as refresh, sorting or filtering. It will show that pop up message.

I suggest you to use setTimeOut() method in newRow.Update(). With delaying or specifying a specific time, you can use your code well.

Hi handy,

can you help me to finish code? thank you ! because I used setTimeOut() methord,but also happen this exception!

Hi Yixin,

E.g in your added row method, you need to specify setTimeOut() with specific time.

setTimeout(function(){AddSomeRows()},600);

Hi Yixin,

I am sorry. Based on your code, the timeout also is not working well. The reccurence of "i", got faster than newRow.Update. So, I would like to correct what I said before. You will still need to use TimeOut to delay for each process. But you must not to use recurrence when add "ID". Because, the time is not correct.

E.g
ID=AAAAA1,AAAAA2,AAAAA3. which (1,2,3) used "i" as repetition.
It is very hard to get the correct time out and mostly goes wrong. 

Therefore, when add multiple rows, you must not to use that repetition.
You will need to assign manually via button click.
e.g
ID=aaaaaa,bbbbbb,cccccc

However, adding multiple row at a once is not suggested because to get the exact delay time is very hard.

Hi,Handy

Thank you for replying,I want to add next new row when  previous new row is complete add in a grid,how can i do ? This question is very important,thank you again!

Hi,

Unfortunately, this scenario could not be done.
Even if It can, the efforts are too big.
If you ask for my opinion, maybe you can try to check in OnAfterReponse clientside event.
You can get if the status is 'add', try to call back your add function again.
However, you will need to find the correct validation. Otherwise, it will always recursive. Maybe you can add some flags or something.

Hi,

thank you for repling,can you give me sample code?

Hi Heny,

I am sorry, but I also could not figure out what is the correct validation for this scenario. As I said before, even though we succeed but the efforts are too big because at default this scenario is not supported right now.
