If you’re testing your ASP.NET project in Internet Explorer 10, you may encounter following error:
SCRIPT5022: Sys.ArgumentOutOfRangeException: Value must be an integer.
Parameter name: (x or y)
Actual value was (some floating point value)
ScriptResource.axd, line … character …
Often it come up when you use some 3rd party libraries, Telerik or Infragistics (in my case it happened in WebDataMenu control).
Here why it happens. Continue reading →
If you use Microsoft Skydrive application on your Windows machine, you know that besides syncing local dedicated Skydrive folder to the cloud it allows accessing your PC files directly (without uploading them to the cloud) from remote location. Unfortunately this feature is available for desktops only, mobile apps are “by design” missing it.
But what prevents you from logging into Skydrive Website directly from a mobile Web browser?
After authorizing yourself with security code you’re in! Albeit this is not as convenient as a native app would be, but until “design” changes this approach allows you to access your PC’s files without installing any additional software on the PC and without downloading any additional app to the device.
This is a solution for specific (and maybe somewhat obscure, but it helped me, so perhaps it will be helpful to someone else) scenario for Infragistics’ WebHierarchicalDataGrid error “Async request failed“.
It could be accompanied by inner errors
Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request
or more generic
Object Reference not set
In this particular scenario WHDG uses manual LoadOnDemand for to populate children (i.e. RowIslandPopulating event is used) and parent grid is sorted by one or more columns. Error is happening when attempting to expand second child or a grandchild. Continue reading →
Infragistics WebDataMenu comes with variety of styles and lets you specify your own. At a very basic it allows you to specify styles for normal menu items and hovered menu items:
<ig:WebDataMenu ID="xwdmMyMenu" runat="server"> <ItemSettings CssClass="MenuItem" HoverCssClass="MenuItemHover"/> </ig:WebDataMenu>
This markup can correspond to CSS classes, for example:
.MenuItem {
background-image:none;
background-color:white;
}
.MenuItemHover{
background-color:rgb(213,224,198);
}
This works fine in most cases, but since the hover/unhover is done via JavaScript sometimes there’re issues. Continue reading →
If you’re using FusionCharts you may encounter a strange issue – chart renders correctly when Flash renderer is in use and displays “Invalid Data” error message when falling back (or forced) to JavaScript renderer.
In most cases culprit is invalid XML data passed to the engine. And while Flash is more forgiving, JavaScript requires strict valid XML. Most often the cause for the issue are characters invalid in XML. Check your data and if they contain following characters – replace them with their encoded values:
" (quote) --> "
' (apostrophe) --> '
< (less sign) --> <
> (greater sign) --> >
& (ampersand) --> &
And the error will disappear.
Happy charting!
Infragistics WebTab control is very versatile and offers rich server- and client-side model. Among client-side events are
SelectedIndexChanged – fires after user has changed the tab to provide ways to interact with newly selected tabSelectedIndexChanging – fires before user has changed the tab to provide ways to interact with currently selected tab and to give user a chance to cancel change.Both work fine if user manually changes tabs by clicking on tab headers, but call to client-side set_selectedIndex() function (which changes tabs programmaticaly) only fires SelectedIndexChanged, skipping SelectedIndexChanging altogether. But there’s a way to make it work.

Everybody heard the story of how town of Santa Clara, CA is now offering all of its resident free Wi-Fi. It’s a really good news and hopefully a beginning of a trend. But a small borough in Northern New Jersey went even further. Continue reading →
FusionCharts states in their documentation that in Bubble and Scatter Charts both X-Axis and Y-Axis must be numeric. But what if you want X-Axis to display some names or dates or other non-numeric values? That is still possible via label attribute of chart’s categories element.
The method below utilizes ADO.NET/VB.NET to build XML for chart data, but similar approach can be easily used in other languages/technologies.
Consider the following ADO.NET DataTable, called dtChartData:
Login Failure Login Success -------------- -------------- ------------- 2013-03-27 1 69 2013-03-26 0 32 2013-03-25 1 86 2013-03-22 0 11
It holds data for number of successful/unsucessful logins for a given date. We want to display this data as a Bubble chart with dates displayed on X-Axis. Continue reading →

Are you looking to secure your computer from the infectious viruses lurking on the Internet? Are you interested in getting your PC running as fast as possible?

Norton 360 is the all-in-one security protection software produced by Symantec that works around the clock to protect not only your computer, but you, from potential security breaches that can happen without you having the slightest idea.
Norton 360 has been updated to find and kill the most serious viruses, implementing a five layer protection system that discovers and terminates threats faster than competing software. The threat removal layer digs deep into the confines of your system to get rid of treacherous threats and viruses, while the network defense layer works to stop threats before they can even reach your system.

While all of this is going on quietly in the background of your computer, Norton 360 is keeping your personal information guarded and your files organized, fixing any other problems that may be occurring and compressing data to keep your system running lightning fast. The security suite can be installed on up to three computers and/or devices, with cloud management controlling all devices from a single, central unit.
