What are the differences between making a binding self-referential via name versus self-referential via RelativeSource? For example: <!-- Self referential via name --> <Window ... x:Name="This" DataContext="{Binding Path=Data, ElementName=This}" > versus <!-- Self referential via RelativeSource --> <Window ... ...
I have a grid of items which is populated using databinding. In the grid I have a DataTemplate for certain cells. I need to access the DataContext of the root element (the one which is hosting the grid) so that I can access additional bindings to support my datatemplate. So you have: Window Window.DataContext = TheDataSourceWithIte...

I have a store procedure that handles paging at database level, receiving @PageSize and @PageIndex. I can create another to return @PageCount, given a page size. Can I make a datagrid do paging at database level without having to develop it outside the control, using the control pager? It seems default use of datagrid paging receives a...

I have a quite complex windows form with a tabbed representation of a grandParent>Parent>Child dataset using a Strongly typed Dataset and bindingsource components. Going down the hirearchy works a treat using bindngsource; my problem is that i have multiple 'parallel' views of some of the data (eg the 1st tab is a summary view of open j...
What is the best way to handle this I have an application where I constantly have to "pivot" 12 month records into one year record/object to be able to display a single year per row in a DataGrid. I have been doing this work up until this point in DataSets with some ugly T-SQL to get the pivot to happen. I'm upgrading this application t...
Given this MXML component: <mx:TextBox id="test" text="{test2.text.length > 5}" /> How can I get an event dispatched whenever the value of test2.text.length > 5 changes? I've tried ChangeWatcher, BindUtils and PropertyChangeEvent, but no luck :( Thanks; [EDIT] Copying my comments from further down: Well... I'm actually using...
It doesn't seem like there is an obvious to implement databinding using jQuery or any other javascript framwork. I'm wondering if anyone has implemented databinding using jQuery in the same vein as WPF databinding, or even your standard databinding scenario (fill a table with the results of this resource). ...
Hello, In my project I have a WPF Listbox bound to an ObservableCollection. Every time I add a new item to the Collection the same item is added to the Listbox automaticly. To display the items in the Listbox I use a XAML Datatemplate. What I want to do is animate an item once when it is added to the Collection/Listbox. Can this be don...
Hi, I have a listbox which is databound to a collection of objects. I want to modify the way the items are displayed to show the user which one of these objects is the START object in my program. I tried to do this the following way, but the listbox does not automatically update. Invalidating the control also didn't work. The only wa...
Hello, Without thinking about it too much, I've been doing something like the following: 1) building a list of SomeBean objects based on the results of a database call 2) putting that list in my command object 3) building a form based on that command object where users can modify attributes of the SomeBeans 4) extracting data out of...
Hello there, I'm new to WPF and its Databinding, but I stumbled upon a strange behaviour I could not resolve for myself. In a Dialog I've got a Listbox with Users and a TextBox for a username. Both are bound to a UserLogonLogic-which publishes among others a CurrentUser property. I want the TextBox to update its text when I click on a...
Hello All, Am new to XAML/WPF and have come across this weird issue: I have a list view to which I set a DataSource. The DataSource is an arraylist of "CatalogPartRows". I create my columns in the code. I then set their cell templates (some of my columns contain combo boxes and check boxes). My problem here is that I need to call a fu...
What method do you use to get a compile time error when the database schema changes occur in an ASP.NET project? For example, if you have a GridView bound to a DataSource, I can only get runtime errors when a schema change occurs, not a compile time error. Intellisense works fine on the code behind using datasets, LINQ, etc, but I cant...

I am binding an array to a DataGridView. I have a column containing file paths which maps to a column of push buttons. I would like to pre-process the file path so that the DataGridViewButtonColumn displays only the file name (sans the parent folders). How do I intercept and pre-process values before they are bound to the columns of a D...
Hello, I was wondering if anyone could explain to me how I could properly bind a group of radio buttons to a boolean variable in the model using JFace data binding. Let me explain the situation first: I've created a class that represents a group of SWT buttons (with the style set to 'SWT.RADIO') that consists of three elements: A label...
