Confirmation box before server side event completes.

[e106199]

Hi all,
is the below scenerio possible?
user submits the form that will insert in db but before the data is written in db i want to make a check. The check function will run and find out if the form data exist in db or not. If it exists a confirmation box will appear and ask user "similar data exists in db, click ok to continue or click cancel to stop operation". Clicking ok will complete the operation and data will be inserted in db and clicking cancel will stop the page execution.

So in the middle of the server side code execution a javascript will alert the user and again depending on the confirmation selection server side event will continue or stop.

Please tell me its possible,
thank you

You can't run server side code from client side script. If you want to do a check if data exists, you will have to write it in server side code.

Jim's correct, although you could implement a Client Callback to do it so that the whole page isn't posted back to the server to do the check.

I wasnt talking about running a server side code on the client side. I was talking about calling a client side confirmation on the server side. the check function is a server side function, if it detects a match i want it to pop up a message and depending on the selection of the message db insertion will stop (this may be accessing server code from client) or it will continue.

thank you
