Wpf - Programmatically Set Height Of Row In XAML?
Jul 26, 2009I'm doing a WPF project and decided to try it out with Visual Basic. So, basically I'm trying to set the height of a row in a Grid. I'm not great at programming but with C# I managed somehow to figure it out, without remembering how. It actually looks like an animation because when clicking the button, the height of one row smoothly goes down to 0. But I'm trying to even reach that property and I can't figure out the context. The row is called "AnimationRow" and I can reach that, but where do I set the height?

View 1 RepliesPass A Variable From Xaml To Program?
May 8, 2010I know I gotta get a book or something because things are just way too hard for me. But before that happens I have what I think should be an easy question.
I want to create a variable in xaml, the angle that a control is currently at, and then use this variable in my VB code (event handler).
Or even better can I, while in VB code, check the current angle a specific control is at so that I can add to the number when setting the new angle?
WPF App - Update Database Directly From XAML
Nov 18, 2010I have a WPF app that is currently driven completely from XAML. All fields, datagrids everything are bound from XAML using ObjectDataProviders objects. I have a DataAccessLayer (DAL) imported into the project. The calls to retrieve data using the ODPs are being used to display the data are all working. Is it possibly to perform inserts, updates, deletes using the methods that exist in my DAL directly from the XAML? I am trying to avoid ANY code-behind here at all to keep the UI a separate entity. I cannot find any clear cut examples with insert, update, deletes on this.
View 1 Replies.net - Set A Code Object As The DataSource For A ComboBox, Using XAML?
Sep 24, 2010I've gotten to a point where I'm trying to add a ComboBox to a UserControl, and to populate it from a collection which exists in code.
I've been getting along pretty much on monkey-see-monkey-do coding for the most part; copying and adapting existing code in order to get the next stage working, but this DataSource stuff has me stumped. I've been through a whole bunch of articles on MSDN this morning and am no closer to understanding than I was when I started.
Let me go through a few of the things that are messing with me, and hopefully you guys will be able to point me in the right direction:
1) None of the [UserControlName].vb files contains any code. All of the code for the UserControls is stored in [UserControlName]Model.vb files, and then code of the following sort is used:
<UserControl
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:l="clr-namespace:MySolution"
[Code]....
1.5) (using bullet points means I can't use <> brackets or code blocks later on. What the hell, markdown?) Anyway...
2) I'm pretty sure I only want a Static Source for the moment, as the items in the ComboBox aren't going to change during execution, at this time. Problem is, all the articles I can find about this are gigantic, complex things about creating XML readers, and populating DataGridViews and sorting data, and on and on and on. I just want to declare that I'm using a frealing List! A List I've already created in code.
So, yeah, I basically need to use a Public Property ComboBoxLines As List(Of String) from a class which isn't the same class as the UserControl itself as the DataSource for a ComboBox.
VB 2010 Express - Make A Application With XAML ?

Can I still convert this to XAML or just see any XAML language somewhere. Cause I need to proove to my Teacher the application I made includes XAML.
View 1 RepliesWpf - DataContext Issues With ListBox After Changes To MainWindow.xaml?
Jun 18, 2012I am new to WPF and the MVVM design pattern this month, and more than a little out of practice in general. To learn, I've been playing around with textboxes, rectangles, and ways to display them in a window. I began with Ashley Davis' excellent "Simple Drag Selection in WPF" tutorial, which walks through creating a view model for a collection of rectangles, binding a listbox to said collection, and styling the listbox with a canvas, creating a data template for the rectangles, as well as basic "rubber band" selection logic.
I have since built on this tutorial to improve the drag selection so that it behaves much more like selection does in windows explorer, and to allow resizing the rectangles from the corners or edges.All was well until I changed the MainWindow.xaml in an effort to include a column on the side for various buttons and controls, thus moving the "editor surface" grid from inside a 1x1 grid on the main window to a column of a 1x2 grid, moving the data template to the grid's resources (since it will be the only element in the window that needs it). As soon as I did this, subroutines that I wrote which interact with the listbox started misbehaving--rubber band selection no longer works. There's no visual indication that listbox items are being selected (they were highlighted previously), and interrogating listBox.SelectedItems.Count after a drag-selection mouseUp event returns a zero.
After some experimentation, reading many questions on this site and sections of my WPF Unleashed book, and going over the msdn databinding overview, as of this morning I still cannot find my mistake(s). I believe it is a data binding mistake or incorrect data context.Some details about the view models involved:
DataFieldViewModel
...implements INotifyPropertyChanged and exposes properties for its (in this case a rectangle and a textbox) X,Y position, width, height, visibility, and selection status (a way to track it across several rubber band selection operations)
PageViewModel
...implements INotifyPropertyChanged, and has among other things an ObservableCollection of type DataFieldViewModel, called DataFields, and exposes it as a ReadOnly Property.Here's a look at MainWindow.xaml.vb and one of the broken subs:
Namespace EditorUI
'
' The main window of the editor.

Wpf - ObjectDataProvider MethodParameter Define Directly In XAML?
Nov 16, 2010I am trying to modify the MethodParameter directly in the XAML. I do have a working example where I am setting it from code. Code version is:

odp.MethodParameters.Add(CType(txtCatId.Text, Integer))
ObjectDataProvider defined in XAML looks like this:

Is there anyway I can retrieve the value of my textbox (which is bound to a separate ObjectDataProvider and put that in place of the hardcoded "0" currently in my XAML? I am looking to have this be completely XAML driven and have not been able to get it working without the code change.
