Ultimate solution (works in SSRS 2012 too!)
Append the following script to the following file (on the SSRS Server)
C:\Program Files\Microsoft SQL Server\MSRS10_50.MSSQLSERVER\Reporting Services\ReportManager\js\ReportingServices.js
function pageLoad() {
var element = document.getElementById("ctl31_ctl10");
if (element)
{
element.style.overflow = "visible";
}
}
Note: As azzlak noted, the div's name isn't always ctl31_ctl10
. For SQL 2012 tryctl32_ctl09
and for 2008 R2 try ctl31_ctl09
. If this solution doesn't work, look at the HTML from your browser to see if the script has worked properly changing the overflow:auto
property to overflow:visible
.
Solution for ReportViewer control
Insert into .aspx
page (or into a linked .css
file, if available) this style line
#reportViewer_ctl09 {
overflow:visible !important;
}
Reason
Chrome and Safari render overflow:auto
in different way respect to IE.
SSRS HTML is QuirksMode HTML and depends on IE 5.5 bugs. Non-IE browsers don't have the IE quirksmode and therefore render the HTML correctly
The HTML page produced by SSRS 2008 R2 reports contain a div
which has overflow:auto
style, and it turns report into an invisible report.
<div id="ctl31_ctl10" style="height:100%;width:100%;overflow:auto;position:relative;">
I can see reports on Chrome by manually changing overflow:auto
to overflow:visible
in the produced webpage using Chrome's Dev Tools (F12).
I love Tim's solution, it's easy and working.
But there is still a problem: any time the user change parameters (my reports use parameters!) AJAX refreshes the div, the overflow:auto tag is rewritten, and no script changes it.
This technote detail explains what is the problem:
This happens because in a page built with AJAX panels, only the AJAX panels change their state, without refreshing the whole page. Consequently, the OnLoad
events you applied on the <body>
tag are only fired once: the first time your page loads. After that, changing any of the AJAX panels will not trigger these events anymore.
User einarq suggested this solution:
Another option is to rename your function to pageLoad. Any functions with this name will be called automatically by asp.net ajax if it exists on the page, also after each partial update. If you do this you can also remove the onload attribute from the body tag
So wrote the improved script that is shown in the solution.

The MSDN article has pretty detailed information about this.
From that the answers to your questions are:
Q1: You should set the Unattended Execution Account if you don't want to set credentials for data sources and want the data source to work even when users are not able to enter their credentials (subscriptions or other scheduled executions.) From the linked MSDN article:
Most SSRS installations do not need the Unattended Execution Account. They use the "Credentials stored securely in the report server" option in the data sources.
Q2: I'm not sure what "run the reports" means, but the SSRS Service account is always responsible for the rendering and delivery of the reports, whether an Unattended Exec Account is set or not. The connections to the data sources will use the credentials specified in the data source. Unattended Exec Account will only be used if the data source is set to "Credentials are not required."
Q3: This account may not be used at all, but SSRS still checks the credentials with the domain. If none of your data sources are set to "Credentials are not required" then I recommend you remove the account from the SSRS configuration.
