Index out of range

[David]

Hi,

I'm currently using a report viewer to show different report. The list of report that can be show is in a comboBox. When I clicked on the button "preview", the reportViewer will show the selected item in the comboBox. I notice that if I click many times on the button preview when the report selected is the same, a error appears. Don't know if it is something wrong I'm doing or what, but here is the error that I received :

Server Error in '/' Application

Anyone know what it mean ? 
Thank you

Hi David,

We're aware of such a problem, but it happens in very specific case, which does not sound like the one you describe. That is why we would appreciate if you open a support ticket and attach a runnable sample project that exhibits the problem, so we can look into it locally.

Best wishes,
Steve

Hi Steve,

As you request, I send you a support ticket  (#453502). Don't know if I done it correctly, so just tell if you don't receive the support ticket

Thank you,
David

Hi David,

We've received your ticket and appreciate the sample project. We would do our best to address this for the upcoming service pack in a couple of weeks.

Kind regards,

I was having the same issue with showing a report inside a tooltip. If I clicked on another tooltip to show the same report with different sourceID it would intermittently show the error:

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

My solution was to disable viewstate for the tooltip containing the report. Perhaps if you disable viewstate for the report 'container' it may help....

Hi,

I was getting also such an error, but on a radgrid with grouping enabled.
I was not using LinQ, but a SQLconnection, so what i found out, is that when grouping is enabled it uses a LinQExpression, i think..
so i disabled it! adding EnableLinqExpressions="false" to the grid elements.

This solved it for me, maybe it can help you?

The problem didn't rise before until i updated my Controls from 2011.2.915.35 to 2011.3.1115.35!
just an update to get the newest skin.dll working.. and my grids with grouping didn't work anymore. It has to be a very small thing, but a big change?! ..

gr,
