View 2 RepliesI'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.
I am trying to bind a few values in xaml to variables declared in the code behind.
e.g.
vb.net
dim test as integer = 2

I need to use the xaml writer to convert in string some controls. What I get is a string like this for example

I've created a Custom Control, and I will be placing a large number of instances of that Custom Control on my xaml page. In working with that Custom Control in the VB Code Behind, how do I do the following?
How do I reference the name of the Custom Control (in my VB code) which was clicked with the MouseLeftButtonDown event? For example, if I have 10 instances of my Custom Control in xaml, each with a different x:name (say 1-10), when a particular instance is clicked, how can I see which one was clicked? I've tried a number of things including e.OriginalSource.Name (which returns the component within the control which was clicked and not the name of the instance of the control). My Custom Control consists of numerous parts and pieces (Rectangles, Lines, Text, etc). Each of these items is a part of my layer. In VB code, once I can reference a particular Control, how can I hide or change certain parts of that control (such as hiding a Line, and changing the text). Also, I need to modify more than just the control which was clicked, so I need to be able to access properties of all of the controls, not just what was clicked. For example, if I click Control instance Test1, I also need to modify Test2, Test3, and Test5 in some way.
Here is some test code I through together as part of a Silverlight project using MS Blend 2. My control is much larger, and I need 200 - 250 instances/copies of that custom control, so I really need to know which control instance/copy was clicked.
My UserControl:
<UserControl
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

To set the checked state of the child node to its parents node i used this code.
mycode
vb
Private Sub CustomerFields_AfterCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles CustomerFields.AfterCheck

I also found the following code on msdn. Whats the difference b/w the two. Both of them works
vb
Private Sub CheckAllChildNodes(treeNode As TreeNode, nodeChecked As Boolean)
Dim node As TreeNode
For Each node In treeNode.Nodes

I have been watching "absolute video tutorial". In those tutorials when doubled clicked on stuffs like "button" or "textbox", a code page appears named as "mainpage.xaml.cs" but when I use Visual Basics and do the same, on double click a page "mainpage.xaml.vb" appears. In this the coding stuffs are different. And when I write the same codes like in tutorial I get errors.

I'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?

Private mpopDropdown As Popup
Public Property Dropdown() As Popup

but they don't seem to expose the property either. I've also tagged the property as <Bindable(True)> but that didn't seem to do anything.
Look at this simple bug :
<textblock (...) Width="0" />
Working great, the textBox appears to be 0px thin. Works with value like, 2, 3, 4...
Now that is NOT working :
<TextBlock (...) />
<TextBlock.Width>
<MultiBinding Converter="{StaticResource WidthConverter}">
[CODE]..................
Why can i set zero value to TextBox.Width in xaml and not in code behind ? By using a converter, when returing 0, the TextBlock.Width is not set to 0 but to "auto", i can read the text

What I am trying to accomplish: Create a dynamic bubble that expands on height and width depending on the amount of text in the bubble. What I researched so far: In a SO article they described utilizing the measurestring function to figure out the exact width or height so dynamic changes in the .cs to the width and height can be accomplished.

I tried saving data from my rich text box using the TextRange to save in xamlpackage format, however my question is basic, what extension should the file have, if I use Xaml, the normal wpf xaml files would not be capable of opening as they are not xamlpackages
View 1 RepliesI 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?
I 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.

Visual Basic 2010. For a school assignment i had to make a application with XAML in it. I made the tutorial Math Quiz when starting up Visual Basic 2010. This was a Windows Form application that only needed VB programming language. Now i made the Math Quiz and finished it but there is no XAML included or what so ever. 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.
