Hi,

As it appears from the stack trace provided, RadComboBox is the control which had caused this error. Could you share the implementation of your RadComboBox so I could inspect it?

All the best,

Hi there,

Thanks, I did realise it was a RadComboBox which caused the error.

My issue is that I have about 6 RadComboBox items on that page and it would really help if I knew WHICH one threw the exception.

Why is this information not shown in the stack trace?

Hi,

The stack trace provides information about the methods which have been invoked prior to the occurrence of the exception.

Kind regards,

Hi Dimitar,

How do we know which among 6 RadComboBox controls has thrown the exception, since the exception doesn't mention the exact RadComboBox control which caused the issue.

Thanks,
Naveen

Hi Naveen,

In general the stack trace does not provide information which instance of the combobox has caused the exception. Could you clarify what exactly is the experienced problem?

Hi Dimitar,

I have a user control (OrderEntry.ascx) which has about 20 RadCombobox controls, some of them hidden.  On  the page load of OrderEntry.ascx control, data bind works fine without any issues. But when I do a post back and try to bind the data again to the user control OrderEntry.ascx, I am getting the below exception.   I could not figure out which combobox control,  is throwing this exception.
Please let me know if there is a way to figure out which combo box control is throwing this exception?   Is there a way to troubleshoot this problem ?   Is this a know issue ?

C# code

              this.OrderEntry..DataSource = custInfo;
                this.OrderEntry..DataBind();     /// Exception thrown in this line.



Exception Type:         System.ArgumentOutOfRangeException
Message:                Selection out of range
Parameter name: value
ActualValue:            NULL
ParamName:              value
Data:
TargetSite:             Void PerformDataBinding(System.Collections.IEnumerable)
HelpLink:               NULL

Just wanted to bump this and say that I agree that a littel more information in the Exception message would be nice, i. e. add the ID of the RadComboBox that caused the exception and maybe even the actual value that is out of range to the exception message.

As it is, it's near impossible to determine the cause of the error if you have more than a handful of RadComboBoxes on a page.

Hey I'm also struck with the same issue. I cant able to find which RadComboBox causing this ArguementOutofRange exception. I'm having nearly 20 RadcomboBox in my page. So kindly share me any advise to find which the RadCombobox causing this issue. 

I'm looking forward for your fast reply with solution.
