You can't wire up to an item in your DataTemplate directly. That's not the way that DataTemplates work. You'll need to do something like this[^] and then add the event handlers.

Thank you Pete for your reply,
I've finally got the solution to this issue through:
string text = (((sender as ComboBox).SelectedItem) as ActionPicture).ImageName
Where ActionPicture is the picture enclosed in the selected. And ImageName is the name of that picture.
Best regards,
Rv

Hi I need to refactor this code..thanks in advance for any help!!
public MyListViewModel GetData(List<UpdatingViewModel> updatingList, MyListViewModel myList)
{
foreach(UpdatingViewModel x in updatingList)
{
x.Gain = myList.UpdatingView[0].Gain;
x.Amount = myList.UpdatingView[0].Amount;
x.Minimum = myList.UpdatingView[0].Minimum;
x.Charge = myList.UpdatingView[0].Charge;
x.abc = myList.UpdatingView[0].abc;
}
}

Start by renaming the method. A method that updates something should not be called Get...!
Fix the compilation error. The method is declared as returning a MyListViewModel, but it doesn't return anything.
Then provide a proper description of what you're trying to do, what you've tried, and where you're stuck.

add new tools to my tool box as *.dll file.
|
|
|
|
|
Simplest way?
Open the Design view on any form.
Open the Toolbox pane.
Close branches so you get "clear space".
Use Windows explorer to browse to the DLL or EXE file containing your controls.
Drag the Assembly file to the ToolBox and drop it there.
You can also create a new Tab first, and drop them on that if you want it a bit tidier.

Now, I am building an application like Russian dictionary. How to program the Russian pronunciation in C #, which library to use? Does the Speech or Speech.lib libraries contain "text to speech" functions for Russian as well as for English? Please Help me solve text russian to speech in C # using library or not?

According to this[^], yes it does. BTW, remove your email address from your signature - that's a sure fire way to get spammed.

Thank you so much. Can you show me how to use the SDK? Currently I'm using C # 2012 but have not installed the SDK in C #? Please show me how to use it.

Hi everybody,
I'm currently developing an application in which I have to drag a video from in a media element into another container (let's say a kind of library). The video must keep playing in the media element and only a copy is "stored" in that library.
All the videos present in the library must be visible in order to eventually be reloaded (through drag and drop) into the media player for vizualization.
Have someone an idea on how this could be achieved?
Best regards,
RV

Hi guys,
Probably a simple task but i'm struggling with it.
I have a list of objects, lets call this a list of Object1. Each Object1 contains a list of another object lets say Object2.
Object2 has 2 properties. 'Name' and 'Value'.
I want to be able to select Object1 where Object2.Name equals a specified value using lambda.
eg
class Object2
{
public string Name {get; set;}
public string Value {get; set;}
}
class Object1
{
public List<Object2> theList = new List<Object2>(){ new Object2(){Name = "Blah", Value = "Blah"}};
}
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
var myList = Object1.Where(m => m.theList.Name == "Blah")
}
}
I hope I explained myself clearly.
Many thanks for your help

There are a lot of things wrong with that!
Object1 is a class, not a collection, so you can;t use Where on it.
Name is not a property of the list, it;'s a property of teh objects teh list contains.
Try this:
List<Object1> myList = new List<Object1>();
myList.Add(new Object1());
myList.Add(new Object1());
myList.Add(new Object1());
IEnumerable<Object1> myResults = myList.Where(m => m.theList.FirstOrDefault(o => o.Name == "Blah") != null);

Thanks Member 12616185,
Yes, Object1 was meant to be a collection of Object1's. My bad for not proof reading. Thanks for spotting and correcting.
Your reply worked a treat. Here's the implementation I used which served my purpose.
var myResults = Object1.Where(m => m.Object2.Select(o => o.Value == "802.11g") != null);
Many thanks again for the help

That's not going to do what you want. It's just going to return every item from the input sequence, since m.Object2.Select(...) returns an IEnumerable<T> which is never equal to null.
Try:
var myResults = Object1.Where(m => m.Object2.Any(o => o.Value == "802.11g"));

I did a test run and you were right! all objects came back in the collection.
I have since implemented your recommendation and that worked
Here's my test code for ref.
using System.Collections.Generic;
using System.Linq;
namespace ConsoleApp3
{
class Program
{
static void Main(string[] args)
{
List<Object1> origCollection = new List<Object1>()
{
new Object1() {ID = 1, theList = new List<Object2>()
{
new Object2() { Name = "Mode", Value = "802.11b" },
new Object2() { Name = "BW", Value = "20" },
new Object2() { Name = "Chan", Value = "1" },
new Object2() { Name = "Tech", Value = "SISO" }
}
},
new Object1() { ID = 2, theList = new List<Object2>()
{
new Object2(){ Name = "Mode", Value = "802.11g" },
new Object2(){ Name = "BW", Value = "20" },
new Object2(){ Name = "Chan", Value = "1" },
new Object2(){ Name = "Tech", Value = "SISO" }
}
}
};
var theCollection0 = origCollection.Where(m => m.theList.Select(n => n.Value == "802.11b") != null);
var theCollection1 = origCollection.Where(m => m.theList.Any(n => n.Value == "802.11b"));
var theCollection3 = origCollection.Where(m => m.theList.Any(n => n.Value == "802.11z"));
}
};
class Object1
{
public int ID { get; set; }
public List<Object2> theList;
}
class Object2
{
public string Name { get; set; }
public string Value { get; set; }
}
}
Many thanks for spotting and fixing this! your a star

Probably simpler to replace the .FirstOrDefault(test) != null with .Any(test):
IEnumerable<Object1> myResults = myList.Where(m => m.theList.Any(o => o.Name == "Blah"));

I'm new to programming and is currently working on Windows Forms where i'm developing a basic Pong game. I'm trying to follow a video which shows how to make a simple Pong game but although it's easy to just copy the code being written i'm not really understanding what exactly is happening since it's not explained.
I'm particulary having trouble understanding the code blocks below.
This block of code is supposed to represent points being increased by one for player 1 i think:
if (ball.Location.Y < 0)
{
pl1Score++;
ball.Location = new Point(this.Width / 2, this.Height / 2);
}
but what does
if (ball.Location.Y < 0) mean? What does the if statement represent?
Aswell as:
if (ball.Location.X > player1.Location.X && ball.Location.X + ball.Width < player1.Location.X + player1.Width && ball.Location.Y + ball.Height > player1.Location.Y)
{
bvelY *= -1;
}
bvelY is a variable representing speed of the ball btw.
And another one is
if (ball.Location.Y > this.Height)
{
pl2Score++;
ball.Location = new Point(this.Width / 2, this.Height / 2);
}
That increases points for player 2 i think. But i'm not understanding the
if (ball.Location.Y > this.Height) statement
I haven't really found any tutorials or pages that explain these things, so that's why i'm asking here. Could someone give a good description of what these things mean? Would be appreciated.
Sorry if this may come off as a stupid question, i'm new here.
