I have a small usercontrol that basically increments or decrements a value by one. The user control has two buttons(one to add and the other to subtract) and a textBlock that is used to display the value. I am going to have multiple instance of this usercontrol in another usercontrol so I can manipulate values of a dataclass that has an...
Hello, I've got a WPF ListBox that's databound to an ObservableCollection of type Employee. In the ItemTemplate, I'm binding the content of controls to various properties, as normal. But for one of the controls in the template, I've made a custom converter class that it uses, and I'd like the converter to get passed in the Employee obj...
I'm using DevExpress XtraReports in a WinForms application, but could equally apply to other reporting tools. I'd like to perform some logic per-row in the report as it is "rendered", on a row-by-row basis. Specifically I'd like to hide a barcode if the data for the barcode isn't available. Currently I'm doing the following: priv...

For example: <TextBlock Text="{Binding Path=SomeField}"/> The text field will change to correctly reflect the value of SomeField whenever PropertyChanged(this, new Pro...

It would be nice if in XAML when I define ItemsControl/ItemsSource="{Binding AvailableContracts}" that Visual Studio would be smart enough to go find the property AvailableContracts on the ModelView which the DataContext is bound to, reflect it, and then when I type: <TextBlock Text="{Binding Path= it would pop up intellisense of the ...

This is no doubt a newbish question, but I have looked for an answer to no avail. My setup is simple: I have a ListBox control defined in XAML and an ObservableCollection<MyClass> in the same class. I am binding the ObservableCollection<MyClass> to the ListBox. Within the hierarchy of this ListBox in XAML, I want to bind to a given My...

Separately, I have a collection ObservableCollection<MyClass> myObjects; and a ListBox called SillyListBox which is bound to this ObservableCollection via: SillyListBox.ItemsS...
Objective-c/cocoa offers a form of binding where a control's properties (ie text in a textbox) can be bound to the property of an object. I am trying to duplicate this functionality in C# w/ .Net 3.5. I have created the following very simple class in the file MyClass.cs: class MyClass { private string myName; public string M...
I'm binding an ASP.NET control to the result of a LINQ query. I'd like to HtmlEncode one of the properties of the contained objects before binding to the control, but I want to do it without altering the data because I do a DataContext.SubmitChanges() later on. How can this be done? Code that won't work: var ds = (from s in dc.Search...

I would like to know if there is a good source of documentation for creating Asp.Net Templated Databound Controls or code samples for simple controls. All the documentation I have seen on the net seems way too complex. Is there a place where it is explained in a simple and easy to understand manner ? I could also be interested in text ...
Hello, A) Question below is based on the assumption that controls are always binded to data source controls in the order they are declared? So in our example SqlDataSource1 will connect to data source prior to SqlDataSource2 and thus lstCities will be populated with values before GridView1, and reason for that being that lstcities was...
