What line does the error happen on? A stack overflow means your code is doing an infinite loop.

Solution 1

A stack overflow means that something very wrong is happening: your code is directly or indirectly recursing and that has used the whole stack. How and where we cannot say from a trivial fragment of code.

So use the debugger: put a breakpoint on the lines

LinkButton lbSelect = (LinkButton)e.Row.FindControl("lbtnUOM");

and

this.RegisterStartupScript("AlertMsg", genUOM.strScr1 + ex.Message.Replace("'", "") + genUOM.strScr2);

and look at the exception detail (particularly the stack trace) when the overflow occurs. It should give you the method and line number that is causing the recursion.

And what does the stack trace show you?

ArvindTomar 4-Jan-18 3:13am

I am using switch statement and around 700-800 cases in switch
how can i trace error in witch case have problem system show error on switch. it is working fine with source code but not working when i host site on IIS

OriginalGriff 4-Jan-18 3:44am

Add a try...catch block around the switch, and log the input value, the stack trace, and so forth. If you can't use the debugger, then you have to fall back on more traditional means of debugging - logging and post crash examination. You use the initial results of the try...catch to refine your logging until you narrow down the problem to specific code and / or input values.

Sorry, but we can't do that for you!
