.net - WPF DataGrid And Avalon TimePicker Binding?
May 26, 2010I'm using a the WPF DataGrid from the wpf toolkit and a TimePicker from AvalonControlsLibrary to insert a collection of TimeSpans. My problem is that bindings are not working inside the DataGrid, and I have no clue of why this isn't working.Here is my setup:
I have the following XAML:
<Window x:Class="TestMainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:wpf="http://schemas.microsoft.com/wpf/2008/toolkit" xmlns:a="http://schemas.AvalonControls/AvalonControlsLibrary/Controls" SizeToContent="WidthAndHeight" MinHeight="250" MinWidth="300">
<Grid>

EDIT 1: I forgot to mention that the binding to SelectedTime TimeSpan works as expected. The problem are the bindings inside the DataGrid.

.net - Silverlight Datagrid Binding With Object With A List Property?
Oct 27, 2011I'm having trouble with some Silverlight functionality. My goal is to get some data from the database and display it in my grid. Sounds simple, however, there are 7 columns that are always going to be there.
The rest of the columns depends on the account. There could be 2 (called Actions) associated with a certain account, compared to another account that could have 5, and the action names can be completely different.
I have successfully been able to return a list of all the possible actions for the given account, and then adding the columns to the grid in the code bihind(VB), and I can bind my data to the grid for all the columns that are already known. The way I store the item's actions, is a Property of type List. My problem is finding a way to iterate through the actions list of the Item object in order to bind those actions to the grid.

View 3 RepliesDuplication Of Tabpage Layout?
Jul 21, 2010I've gone through various thread, posts, classes and walkthroughs on sites but seem to be coming up short either in my understanding or what is/should be going on.I have a very simple data entry tabcontrol (think like microsoft excel but textboxes, labels and the odd combobox rather than a grid). When I click one tab it creates a new tab and names it according the sequence (no problems so far). Here is the crotch kicker (for me at least). I need the first tabpage layout on all additional tabpage so that data can be entered in each separately and stored with constant "processing" (adding and subtracting ).What would be the best approach to doing such a tabpage duplication?
Currently a User control library inheriting from tabpage seems like a good idea but with the 40 or so controls on it is this actually going to function like the first tabpage (as in the one i have now not the one I'd have if i used the user control instead).Do I take the raft of code the designer creates automatically for the tabpage and its controls and simply add them to the click event? Would this create duplication problems with name or would it be ok as they would be tabpage1.lblName and tabpage2.lblName?
