Hi experts,

My command is declared in a ViewModel.cs file, command is defined in Command.cs file. the command is being called in XAML page. Codes from these three files are here for your ready reference. I searched web a lot, but did not overcome my problem.

hi experts,
I myself sorted out this issue. I added following lines above item template. Hope this post will help others.
<i:Interaction.Triggers>
<i:EventTrigger EventName="SelectedItemChanged">
<i:InvokeCommandAction x:Name="abc" Command="{Binding Path=test, Mode=TwoWay}">
</i:InvokeCommandAction>
</i:EventTrigger>
</i:Interaction.Triggers>

There is a free tool here[^] that might help you do this as well.
The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it.

Hi Abhinav,
I tried this but it did not worked for me. I need this to be incorporated as one of the grid row in an xaml file.

Hello,
I'd like to display my own WPF window at start up, which means I don't need standard splash screen. But, I'd like exactly the same behavior as splash screen. It means my own WPF window should appear right after the aplication started and stay visible until the main application window shows up.
Thank you in advance.
Regards,
Goran

Hi,
Due to business requirements, I have to have something like a process to run all the time to retrieve data and do processing with it...
My first guess is to create a windows service so that it can be started and be left running.
Question:
Is windows service the best choice for my requirement or can I have a wcf i.e. .svc file to do the same thing i.e. (get started and be left running all the time). ?
|

Yes - a windows service is what you need.
A WCF service is for communications between a two clients or a client and a server. You would use a WCF service *inside* your Windows service.

A book is what he needs. He's been posting basic stuff in this forum for weeks now, and a good introductory text or two would serve him better.

Yeah, I know - I decided to take the chance that he would have gotten some form of a clue by now, but I guess not, based on his response to my answer.
In the end, all you can do is point and laugh...

Well, unfortunately, you keep answering his retarded questions. If you stopped, maybe he *would* get a clue. I think its time Arkiboy stepped up and became an Arkiman and quit depending on people to spoon feed him.

I'll give him answers to a certain degree, but he's gonna have to cowboy up and do most of the legwork himself.

Just you wait. He will start asking questions like "I went to the toilette, but there are no bathroom tissues. What do I do?"

I would like to return the data to the GUI from the windows service.
1- Should the GUI call WCF which gets the data from window service?
OR
2- Should the GUI just call the windows service to get the data?
Thanks

The windows service shouldn't return the data, it should store the data locally, and send out a system-wide message that new data is available. If a desktop application is running that knows about the message, it can then load the data from the local source.

I see what you mean and this is what I am trying to devlope at present.
But where does WCF come into this?
Thanks

Buy some books. Read them. Learn from them. Stop expecting us to spoonfeed you.

Just you wait. He will start asking questions like "I left my car keys in another jacket. What do I do?"

This is an inappropriate question. He'll get better, but the question is whether or not we'll all live to see it. There's no reason to ban him, and foltering users in a programming forum is a bad idea.
