If I have a mix of projects using different frameworks what does the xap use.
.Web only has 4 available
Silverlight app is set to 5 (xap is generated by this)
Utilities is using 4 (5 is available but it has not been complied into 5 yet) and is referenced by the Silverlight app.
Am I going to get any benefits from SL5?

If you are not using any SL 5 features, you are not going to get any benefits.
It does not matter whether you compile your code using SL4 or SL5.

I was under the impression the the runtime is quite different from 4 to 5 and 4 will run in a sandbox within 5 and have no optimisation.
Interesting issue, if you have a WCF in 4 that references a models library in 5 the model library is not available when referencing the service in the SL5 app.

Hi All,
I want a solution/sample code to do following scenario:
I want to bind Hierarchical data to a tree view. When I click on tree view the child data(second level data) should display in List view (Tree view should not display the child data i.e no expand). If the child's are three levels, the second level data should expand in tree view itself. and when click on second level, the third level data should show in list view (The third level data should show in tree view).
Thanks in advance,
|

What have you tried? Have you spent any time researching this? Do you think someone's going to write the code for you and post it without you even trying?
There are plenty of examples of using a treeview in WPF. I suggest you research first, the come back and post questions specific to any issues you're having.
If it's not broken, fix it until it is

I don't often vote 1 but you deserve it for this question. Your requirements are very simple and there are a myriad of examples that will show you how to do this. Search the articles and Google, read the articles and work with the examples, when you have a specific problem then return with a sensible question.
Oh if you really are after someone to code this for you then go to rentacoder or elance with a few pennies, that is what those sites are for!

Thanks for your valuable responses.
I was a wpf beginner and I tried and I found plenty of examples But I couldn't achieve what I want exactly. So I posted. Anyways, thanks again for your valuable responses.

Infragistics has a tree view that supports hierarchical structures by default.
|
|

|

There's an example of this being done here: http://msdn.microsoft.com/en-us/library/ms171645(v=vs.80).aspx[^]
The example creates a windows explorer style interface, with the directory data in the treeview, and the files in the listview - but you could easily adapt this so that the lowest level of directories were in the listview instead.
Hope that helps.

I found the answers from Kevin Marois amd Mycroft Holmes to be very disrespectful and insulting. I am really sorry for this. They could have instead provided some rough guidelines or chosen not to answer. But no moderator should have given them the right to answer in such a disrespectful manner.

I completely agree. Rudeness is not required to instruct someone how to research and post questions in the forums.
Even a simple link to How to get an answer to your question[^] would not be disrespectful and at the same type will help new users how to start and not run away from CP.
If they run away from CP, they will never get the chance to become contributors on the future.
While I'm at it, maybe I should post this link to them:

Wow you must have such a sensitive soul. If you read the response you will note that I was not trying to answer the OPs question but give an explanation of the 1 vote. I dislike the tendency to simply respond with a 1 vote to a lousy question.
The original question showed a complete lack of effort to help himself and therefore deserved no respect whatsoever.
I am a little surprised the OP made the effort to create an account to ask the question when it would have been simpler and quicker to do the tiniest bit of research to help himself. I am impressed however that you and Fabio did not resort to tit for tat 1 voting.
As this has the potential to degrade into a flame war I will leave the discussion here.

I don't disagree with the voting, I disagree with making the OP feel stupid with things like:

Don't want that to happen:

You had already made your point. Editing your post to put that in was unnecessary. I haven't voted on your post, but it appears to have offended someone (and I don't think it's Mycroft).

It seemed that he had not read what was there when I pointed it in the first time, because he claimed the OP deserved no respect, so I pointed it out again.

Maybe, or maybe someone just does not agree with me and voted me down.

Please rebuild the solution and try again.

|

|

ok..... but how i can do it
|
|
|
|
|
Build->Clean Solution. This will clear the bin/Debug folder.
Then Build->Rebuild Solution.
This will rebuild the entire solution.
If the file is still missing, I would suggest making sure it's added to the project, but I think you would see obvious issues like that...

Hi, i tried this code to parse CSV file and save data in a wpf data grid, the code is correct but i can't store values on datagrid
this is a class wich contain the code:
public class CsvParser
{
public List<string[]> ReadAndParseData(string path, char separator)
{
var parseData = new List<string[]>();
using (var sr = new StreamReader(path))
{
string line;
while ((line = sr.ReadLine()) != null)
{
string[] row = line.Split(separator);
parseData.Add(row);
}
}
return parseData;
}
}
}
the is the code behind; assigned to event click on boutton
List<string[]> parseData = csv.ReadAndParseData(datasource, ';');
foreach (string[] row in parseData)
{
MessageBox.Show(""+row.GetValue(0));// i get the correct value
dgvreceipient.Items.Add(row.....);// but i get a empty datagrid
}

Why do you persist in trying to do this the wrong way? You could solve this simply with an ObservableCollection and a little bit of binding.
public class CsvReaderViewModel
{
public ObservableCollection<string> CsvLines { get; set; }
public CsvReaderViewModel(string datasource)
{
List<string> csv = new CsvParser().ReadAndParseData(datasource, ';');
CsvLines = new CsvLines(csv);
}
}Then, "in your code behind", all you need do is (make sure you have called InitializeComponent before you try this):
CsvReaderViewModel vm = new CsvReaderViewModel("my source");
DataContext = vm;Finally, you just need to set your grid ItemsSource to CsvLines.
BTW - you have posted and been told often enough, format your code blocks using the pre tags. It's not hard to do.
