I'm pretty sure my recommendation will fix both your issues.
When Silverlight 3 was released, I uninstalled Silverlight,
the silverlight VS tools, and the toolkit. Then I downloaded and
installed (in order) everything on the Get Started Building Silverlight 3 Applications[^]
page. Except for some namespace shuffling (they keep changing stuff for WPF
compatibility and when controls get migrated from the toolkit to the
framework) everything works correctly.
The toolkit is essentially beta, so I highly recommend keeping
up the latest version. They are fixing stuff every few months.
July is not the newest.

Hi,
I am working on a silverlight application. In this I need to access session variables in silverlight application.For this I created a WCF service to get the session variable. For this I used the following code:
In service
[ServiceContract(Namespace = "")][AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
UserId = int.Parse(System.Web.HttpContext.Current.Session["LoginUserID"].ToString());
In web.config file:
<serviceHostingEnvironment aspNetCompatibilityEnabled="true">
but I am getting the following error:
System.Reflection.TargetInvocationException: An exception occurred during the operation, making the result invalid. Check InnerException for exception details. ---> System.ServiceModel.CommunicationException: The remote server returned an error: NotFound. ---> System.Net.WebException: The remote server returned an error: NotFound. ---> System.Net.WebException: The remote server returned an error: NotFound.
If any one have any idea to solve this or directly access the session variable in silverlight application please reply me.
Thanks in advance.

Hi,
I am getting an exception while calling a WCF service in silver lght application.This exception is as below.
Exception:
An exception occurred during the operation, making the result invalid. Check InnerException for exception details. ---> System.InvalidOperationException: The underlying channel factory could not be created because no binding information was found in the configuration file for endpoint with name '*'. Please check the endpoint configuration section with name '*' to ensure that binding information is present and correct.
If anyone have idea to solve this please reply me.
Thanks in advance.

First idea is this: follow the suggestion of the exception and verify your binding information. You have to have a basicHTTPBinding in order to use WCF with Silverlight. Try Googling "Using WCF with Silverlight 3.0" and you will discover a wealth of information.

Maybe you could actually reply to peoples replies instead of
asking the same question over and over.
I asked before: Are the endpoints configured properly on both ends?
From your posts, I'm thinking no.

In addition to properly defined endpoints, you can only connect using basicHTTPBinding not wsHTTPBinding

Hi,

My Problem is "HOW TO BIND THE IMAGE TO DATA GRID CONTROL FROM
DATABASE"

Thanks and Regards

What form is the image data in?
Without seeing a sample of the data class used as the DataGrid data
and what your DataGrid column definition looks like, it's difficult to
give a precise example...
Can you post a simple example of the XAML and the data class?

Can you use the Datagrid.SelectItem property to
get the data for the entire row?

You'll need to bind the SelectedItem to a property on your view model. You should then be able to set the property from the code. Don't forget to notify property change

Hi together,
for a benchmark (WinForm - WPF) I want to measure the drawing time of an thrid party control (for WinForm and WPF available). Under WinForm I created a test project, derived the thrid party control and override the OnPaint and OnPaintBackground Method to measure the runtime. I just started programming in WPF, so I do not now who I can do this measureing under WPF. Does somebody have an idea?
thanks in anticipation

You can't post the EXACT error?
Are the endpoints configured properly on both ends?

Hi all,
I have to do printing of visuals say Grid contents, over multiple pages supporting basic printing functionalities like changing the margin, orientation ,paper size etc without invoking Print Dialog.

2. If Print document allows these features, please let me know how to convert the visual as a IDocumentPaginatorSource to pass it to the Print Document function?
Please reply asap...Very urgent... please provide sample code if you have...

What kind of service? If WCF, see here:
Designing Service Contracts[^] ("Out and Ref Parameters" section)

My code is as bellow on services1.svc.cs page
[OperationContract]
public DataTable getEmpCode(System.DateTime dt1, System.DateTime dt2)
{
string s = "";
tbl1 = createTable();//tbl1 is a DataTable
//createTable() is a function which generating table and return it
db = new DataClasses1DataContext();
var objECode = from user in db.UserMgmts
where user.ProjectName == "WapCos"
select user;
//return objECode.ToList();
List<UserMgmt> l = objECode.ToList();
int intCount = objECode.Count();
for(int i = 0; i < intCount; i++)
{
drw1 = tbl1.NewRow();
drw1[0] = l[i].ECode.ToString();
s= getCost1(l[i].ECode.ToString(), dt1, dt2);
drw1[1] = s;
tbl1.Rows.Add(drw1);
}
return tbl1;
}
i want to retrive data of tbl1 on page.xaml.cs page by clicking any button.

First of all, Silverlight doesn't have a DataTable class...
Is this your own class?
Second, I don't see anything having to do with "ref" there.

Actually firstly i was using ref type variable since i had no idea of using ref keywords in silverlight so i changed my logics and used there DataTable but i came to knew from you that Silverlight don't have DataTable class.
Over all i am getting some data by Linq and kept it in DataTable after performing few manipulation.Function that creates DataTable is as bellow.(all code are written on Services1.svc.cs page)
public DataTable createTable()
{
DataTable tbl2 = new DataTable("UserCost");
DataColumn DC0 = new DataColumn("DT_ECode");
DataColumn DC1 = new DataColumn("DT_Area");
tbl2.Columns.Add(DC0);
tbl2.Columns.Add(DC1);
return tbl2;
}
To create DataTable I add using System.Data; namespace
Function that performs operation and keeps data in a table is:
public DataTable getEmpCode(System.DateTime dt1, System.DateTime dt2)
{
string s = "";
tbl1 = createTable();//tbl1 is a DataTable
db = new DataClasses1DataContext();
var objECode = from user in db.UserMgmts
where user.ProjectName == "WapCos"
select user;
//return objECode.ToList();
List<UserMgmt> l = objECode.ToList();
int intCount = objECode.Count();
for(int i = 0; i < intCount; i++)
{
drw1 = tbl1.NewRow();
drw1[0] = l[i].ECode.ToString();
s= getCost1(l[i].ECode.ToString(), dt1, dt2);
//s is some manipulated value against every ECode by another function
//getCost1(string empCode,date1,date2){some codes...}
drw1[1] = s;
tbl1.Rows.Add(drw1);
}
return tbl1;
}
My objective is to use tbl1 data on Page.xaml.cs page.Then what should be another way to use this tabular data on Page.xaml.cs page instead of DataTable.
