Have a read (and play about) with the code that Josh Smith put together here[^].

That is the simple way. Don't try and complicate things for yourself.

Dear Josh,

I went thru your article and many more articles for bindinf a tree view with database. My problem is still unresolved.
my requirement is, I have three tables linked togather as below

1-Order table contains, partyCode and orderNo.
2-Item table contains, orderNo & ItemCode.
3-Stages table contains, orderNo, itemCode & stageCode.(Same stageCode can appear in the table for different items, but not for same Items. Items may or may not have stages. If Item has stages, then entry for such Item will be available in stage table. Otherwise not.)

I am unable to generate a tree in below manner:

Tree display
ord1
...Item1
.......stage1
.......stage2
...item2
.......stage1
.......stage2
.......stage3
...item3
...item4
...item5
...item6
...item7
...item8
...item9
ord2
……
ord3
…….

please help me in generating a tree of such type. I am using dataservices to getch the data from database.

So you want a simple way, try this one :

I am sure it will end up even more complex though. Laugh | :laugh:

UriMapper (and stuff) [SOLVED (sorta)]

#realJSOP15-Apr-10 6:23

I have the following xaml (nonessential markup removed in the interest of brevity):

<navigation:Frame x:Name="ContentFrame" >
    <navigation:Frame.UriMapper>
        <uriMapper:UriMapper>
            <uriMapper:UriMapping Uri="/{pageName}" 
                                  MappedUri="/Views/{pageName}.xaml"/>
            <uriMapper:UriMapping Uri="/FMChart/{metricID}/{orgID}" 
                                  MappedUri="/Views/FMChart.xaml?metricID={metricID}&orgID={orgID}"/>
        </navigation:Frame.UriMapper>
    </navigation:Frame.UriMapper>
</navigation:Frame>

I'm creating the HyperLinkButton objects dynamically (in code), like so:

int metricID = 1;
int orgID = 1;

HyperlinkButton button = new HyperlinkButton();
button.Name        = Guid.NewGuid().ToString();
button.TargetName  = "ContentFrame";
<br />

<big>string url = string.Format("/FMChart/{0}/{1}", metricID, orgID);</big> // <<------

button.NavigateUri = new Uri(url, UriKind.Relative);

When I click the bbutton, the browser renders a blank page, and eventually presents me with a REALLY long stack trace (InvalidOperation exception). If I take the parameters out of th indicated line:

string url = "/FMChart";

...it works as expected (brings up the desired page).

What am I doing wrong?

SOLUTION ===========================================

It seems that the order of the UriMappers in the XAML matters. Originally the mapping I specified was the last one listed in the group. When I changed it to be the FIRST item in the group, it worked. The reason I say this is"sorta" solved is that I think this is a bug in Silverlight. It was a unique mapping (compared to all of the others) and should have been discovered by Silverlight in the original order.

Not absolutely certain, but should the Uri not be Uri="/FMChart/{metricID}&{orgID} ?

I tried that too, and that didn't work either. BTW, the format of the string has been represented both ways (and on the official MS site, it's the way I have it). I've trie it the following ways:

uri = "/FMChart/{metricID}/{orgID}"
// the space between the & and the amp; in the next line is due to CodProject's 
// now completely screwed up auto-formatter
uri = "/FMChart/{metricID}& amp;{orgID}" 
uri = "/FMChart/{metricID}&{orgID}"

This is interesting.
Let me see if I get some time to play around with the navigational framework.

Encrypting app.config through code [modified]

Hi,

I am trying to encrypt my appSettings section through code but i am facing some problem.

This is what is am doing
-- app.config

<? xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <add key="Encrypt" value="Encrpyted"/>
  </appSettings>
</configuration>

--Code

string s = System.IO.Directory.GetCurrentDirectory();

s = s + "\\Test_Encrypt_1_WPF.exe.config"; // "Test_Encrypt_1_WPF" is my exe name

Configuration config = ConfigurationManager.OpenExeConfiguration(s);

AppSettingsSection section = (AppSettingsSection)config.GetSection("AppSettings");

if (!section.SectionInformation.IsProtected)
{
     section.SectionInformation.ProtectSection("RsaProtectedConfigurationProvider");
}
config.Save(ConfigurationSaveMode.Modified);

In the above code the "section" object is showing null i.e. i am not able to find the "AppSettings" section.
I even tried configuration/appSettings but the same result.
Can anyone please help!

Thanks in advance,

Samar

Hi All,

I got the solution myself.

Instead of

string s = System.IO.Directory.GetCurrentDirectory();
s = s + "\\Test_Encrypt_1_WPF.exe.config"; // "Test_Encrypt_1_WPF" is my exe name
Configuration config = ConfigurationManager.OpenExeConfiguration(s);

i wrote

Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);

This worked!!

Samar

Hi Mark,

I was not able to find the link you have mentioned when i was searching.

The solution in the link looks pretty similar to what i have tried.

Please do let me know if i am incorrect in any way on stating the above.

WPF Toolkit Datagrid Performance issue in rendering

Hi All,

I am facing a performance issue with WPF Toolkit datagrid. In my application I have created a view containing multiple Data Grids (around 15) with about 100 rows in each grid. The view shows 15 rows for each grid. The grids are placed in an ListView, so when I scroll in the list view I am experiencing a performance hit.

Can anyone guide me to resolve the issue.

Thanks

I have no idea about the datagrid, but did you Virtualized your ListView?

You would need to add C# code in your code behind file. This code should generate a button dynamically.

You may also try creating a UserControl and then use it for your application. I think, it will be useful and handy in your case.
