Fill combo box in silverlight using collections !!

Hi all...

I am still having issues in loading combo box in silverlight dynamically.

My requirement is -

There is a Silverlight Page(.xaml file), Class file(class1.cs file), Service file(svc.cs file).

I have written the [OperationContract] in Service file(svc.cs file).

I have written the EventHandlers and Listeners and Methods in Class file(class1.cs file).

There are 2 methods: 1)CheckLogin() and 2)FillData().

And finally, invoked the method in Silverlight Page(.xaml file).

There is no error. But during debugging, the control goes to the CheckLogin() after debugging FillData() method.

And the combo box is not loaded.

Please help me out.

True !!

I did your code in a new silverlight project !! It worked....

But the SilverlightServiceReference is not getting updated and hence, I am not able to make the event handlers to load the combo box...

To update the ServiceReference, I did a right click on the servicereference and clicked Update Service Reference.

Still not working !!!

Thanks !!!

then change the return type to  list

Very true !! But, in the combobox, I just want the First Names column..... I am unable to get that !!
The linq query is -
var result = from users in context.Tbl_FirstName select users.FName;

You have return type as Tbl_FNames.

But you are returning list of string.

public List LoadTypes()
        {
            try
            {
               
                    context = new ComplaintManagementSystemDataClasses1DataContext();
                    
                  return context.Tbl_FNames.ToList() ;
                 
            }
            catch (Exception err)
            {
                err.Message.ToString();
                return null;
            }
        }

Hi,

I have to write a method in WCF Service in silverlight as below:
public List LoadTypes()
        {
            try
            {
              
                    context = new ComplaintManagementSystemDataClasses1DataContext();
                   
                   var comtypes = from types in context.Tbl_FNames select  types.FNames.ToList() ;
                  
                  return comtypes.ToList();
                  
              
            }
            catch (Exception err)
            {
                err.Message.ToString();
                return null;
            }
        }

List strlist= from names in TblNames select new { names.FName}.ToList();
