In my current Silverlight project, I’m using the DatePicker control, which is part of the Silverlight SDK. In one scenario, the DatePicker with TwoWay binding is embedded into a User Control, which itself is embedded into another User Control. The format is “dd.MM.yyyy”. Entering e.g. 23.11.2011 works fine, means the …

One of the great things of Silverlight – from my point of view – is the introduction of converters to format the content if a control, e.g. a text box. Well, the idea itself isn’t new, but it is the first time I saw it built in a Microsoft UI …

What a “feature” 🙁 In one of the LOB apps I’m building, I set some of the text boxes to enabled, read-only and no tab stop. Then I needed top copy the content of one of these text boxes into the clipboard. It was not possible! Because you cannot mark …
For re-use purposes, it is helpful to put Silverlight styles into a separate class library; let’s call it ResourceLibrary in this example. In the class library which is using the styles from ResourceLibrary, one should declare a Styles.xaml, which only contains a reference to ResourceLibrary: <ResourceDictionary xmlns=”http://schemas.microsoft.com/winfx/2006/xaml/presentation” xmlns:x=”http://schemas.microsoft.com/winfx/2006/xaml”> <ResourceDictionary.MergedDictionaries> <ResourceDictionary …

In Silverlight 4, the new Binding property StringFormat was introduced. It’s a nice thing, e.g. if you want to display numeric values with digit grouping and a fix number of decimal places. The syntax is equal to the String.Format: {Binding DataContextProperty StringFormat=’#,##0.00′}. One can, of course, use it for other …

In an application I built, using Silverlight Client and WCF Service, the application threw an exception when the request data passed by the client to the server exceeded about 64K (might be a little bit less). Using a TCP tracer, I saw that the client received a “bad request” error. …

You are wondering why your DB-transaction, startet by using(TransactionScope scope = new TransactionScope(timeout)) runs into a timeout after 10 minutes? Because the <machineSettings maxTimeout=”00:10:00″/> in the system.transactions section of the machine.config has a default value of 10 minutes. And whatever is set as timeout of the TransactionScope by code – …

Given you have an abstract base class with non-public member, and a derived class with other non-public member too. Now you want to unit-test some of the non-public member (methods) of the derived class. Prior the call of the method of the derived class, you need to set some non-public …

Using Telerik’s RadGridView, one can connect the add, update, cancel and delete command to RadButtons by setting the Command=”telerik:RadGridViewCommands….” properties of the buttons and link to the grid by setting the CommandTarget=”{Binding ElementName=GridViewName}” property. For some reasons, I needed to disable the buttons, depending on the rights the currently logged …
In case you do open a transaction using isolation level snapshot, make sure you do not disable connection pooling in the connection string (do not set ‘Pooling=false’). Otherwise, opening a connection after you opened and closed another one, you will receive an exception telling the transaction cannot be extended.
