Question

I upgraded an asp.net website from 2.0 to 4.0 framework. This websites uses farpoint. After framework upgrade, one of the page is throwing the error mentioned in the title. FarPoint.Web.Spread assembly registred in this page and FPSPREAD is used. FarPoint.Web.Spread.dll assembly version is 3.0.2003.2005. Do i need to refer any latest dll of the same or is there any other fix for this issue? I am very new to farpoint, Please help me....

Many Thanks, Sreekanth Mohan

Set `EnablePartialRendering` property of ScriptManager to `false` and check where exception comes from — Yuriy Rozhovetskiy, Feb 19 '13 at 07:50
EnablePartialRendering= false is not working. Thank you for your comment... :) — Sreekanth Mohan, Feb 19 '13 at 07:56
I understand that this won't fix a problem but which error message you get with disabled partial rendering? — Yuriy Rozhovetskiy, Feb 19 '13 at 09:20
"Input string was not in a correct format" is getting with disabled partial rendering...!! now only i am getting this on FPSPREAD paging. Thanks @YuriyRozhovetskiy — Sreekanth Mohan, Feb 19 '13 at 11:27
From the error message, it seems this is some type casting issue. But don't know from where it is throwing...!! Please help me... :( — Sreekanth Mohan, Feb 20 '13 at 07:17

Spread 3 probably isn't compatible with 4.0 Framework. Have you tried upgrading Spread? You can download a free trial of Spread.NET 6 here
