Thanks Rahul for your reply.

We are sure that input being provided is in proper format. Basically we are trying to update Title field (which i beleive is type of String).

For testing purpose I also tried entering numeric values but all the times error is same.

If i make a fresh entry to the list and also for other entries in the list update is possible.

Pls advice :)

From the stacktrace it seems that you are trying to convert a string value to number ??

If so, ensure that string contains an expected string, i.e. something which gets converted to number without exception.

I agree with you Priyanka, indeed stacktrace tells "String is being converted to number" and I really wonder why it has been coded this way.

In the entry only, Title is Required field and by all means it has to be string only. I removed all other entries and tried with only Title filed at no avail.

I am not a developer and hence wondering around this issue. Can you please advice a little more on this ? Which file do i need to rig up to find why it is converting String to Number etc...? or what is the acceptable string value (sample example)

Thanks

I assume that you are using the OOB sharepoint Edit page to edit the item.

Based on this assumption:

1) Are you using any special character in the title's value?

2) Did you tried creating a new custom list (with only title column) and tried updating the value for the same ?

3) Are there any event handlers associated with the List. You can check the same using sharepoint Event manager available on codeplex.
