There was an error deserializing the object of type WebService ResponseBody. The maximum array length quota (16384) has been exceeded while reading XML data. This quota may be increased by changing the MaxArrayLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader. Line 1, position 49035.’. Please see InnerException for more details.

You can resolve this error by adding these lines at client app.config or web.config

<readerQuotas maxDepth=”32″ maxStringContentLength=”83886088″
maxArrayLength=”163848″ maxBytesPerRead=”40969″
maxNameTableCharCount=”163849″ />

so the full setting as follows



<binding name=”PATWebServiceSoap” >

<readerQuotas maxDepth=”32″ maxStringContentLength=”83886088″             maxArrayLength=”163848″ maxBytesPerRead=”40969″             maxNameTableCharCount=”163849″ />




Happy coding:)

You can set the scroll of DataGrid or ListView to top programmatically. Here is the code

  ScrollViewer scrollViewer = GetScrollViewer(gridViewName) as ScrollViewer;

public static DependencyObject GetScrollViewer(DependencyObject o)
if (o is ScrollViewer)
{ return o; }

for (int i = 0; i < VisualTreeHelper.GetChildrenCount(o); i++)
var child = VisualTreeHelper.GetChild(o, i);

var result = GetScrollViewer(child);
if (result == null)
return result;

return null;

Happy coding

There is no datepicker control in WPF  .NET 3.5 by default.

We can get this by using WPF Toolkit.

You can download WPF toolkit that contains datepicker from

Make a new tab in toolbox

Right Click the tab and select Choose Items

Go WPF Components tab and Click Browse

Go to Tool Kit Installed directory probably C:\Program Files\WPF Toolkit\v3.5.40128.1\

Choose the WPFToolkit.dll and click open.

Click OK.

Now you can see the new tab is populates with some new controls

Now you can drag and drop the datepicker in your page


Happy coding 🙂

Accordion Control in WPF

October 3, 2012 Leave a comment

Basically there is no Accordion control in WPF. You have to use a 3rd party tool or you have to make it by yourself using StackPanel and Expander controls. I found a nice Accordion Demo here

thank you Liang.Rui for this effort.
