DataBinding + Extension Method Problem

Hi,

Could someone explain me how to provide some value to the parameters in a finder method. For exemple I know that the BDC list WP use this method. Is there a way to provide some value for those parameter at runtime? I really don't understand (even after some deep search on the web) where are the values for the parameters from and how we can connect to them. Even with C# code I can't find any information on how it work.

I don't want to define my parameters as filter in the ADF because then I will have this filter section in my BDC list WP (or is there a way to get rid of that?). Actually one of the parameter should be automatically calculated from a value in a SP list, the other parameter should be provided by my own filter web part.

Thank you for your help.

Hi;

I want to canceling an asynchronous method.

How can me it?

i.e:

public IAsyncResult BeginGetAllUsersCount(object sender, EventArgs args, AsyncCallback callback, object state)
{
       if(_index==0){
       
       //Canceling asynchronous operation
      }
     return AdapterUser.BeginGetAllUsersCount(callback);
}

   public void EndGetAllUsersCount(IAsyncResult asyncResult)
   {
     _totalRowsCount = AdapterUser.EndGetAllUsersCount(asyncResult);
   }

 Thanks

I have a WCF Service and a client application. WCF Service has an operation contract (say UpdateTables()) with IsOneWay = True. I call this method of WCF Service from my client application using the code below:
   Private Sub UpdateTable_Client()
        Dim WCFSvcObject As New MyFirstWCFServiceClient
        Dim WCFSvcData as new MyFirstWCFDataRequest 'DataContract object
        WCFSvcData.TableName = "Customer"
        WCFSvcData.ColumnName = "Name"
        WCFSvcObject.UpdateTable(WCFSvcData)
        Catch ex As Exception
            Throw ex
        Finally
            If WCFSvcObject  IsNot Nothing Then               
                WCFSvcObject.Abort()
            End If
        End Try
    End Sub

Sometimes this call reaches to WCF Service successfully but sometime it lost and UpdateTable() method could not be invoked on service side. I am not sure but I think WCFSvcObject.Abort() code aborts the WCF request before it reaches to the service. I can not use Close() method here as my client application hangs on the Close().
Please suggest me what may be the reasons of the client call could not reach to the WCF Service. Should I not use Abort() method. If yes then how can I dispose the WCF proxy(since Close() method is not working here).

I added the extender and when i tried to add the method this message poped up;

Cannot create page method "GetCompletionList" because no Code Behind or codefile was found.

does anyone know why this is happening?

Thanks  =)

I have a class that runs calculations on numbers and populates the results to my SQL database.  My code behind page instantiates the class object, and in a loop it makes use of the method five times (once per loop).  Essentially, my code behind collects the information from controls and passes the information to the class method for processing.  The method works just fine most of the time.

On one of the iterations I get a error before the code even gets to the class.  The error is, "Arithmetic operation resulted in an overflow."  What strikes me as odd is that while stepping through the code, the loop crashes with that error before getting to the class that runs the calculations.  Additionally, no arethmetic operations are performed on the form's code-behind page (which calls the method).  I even put a break-point on the class constructor but the code crashed before reaching that constructor.

The information being sent is the results of matches from a sporting event.  As a troubleshooting measure I changed the order of the matches by deleting them an re-entering them into the database in a different order.  Again only this one particular match crashed.

Here is the code that crashes:

cRating.SetRating(dMatchDate, iSetID, 8, iHPlayerID, 

I am using gridview, in ItemTemplate  I am using dropdownlist which has the hard-coded value, I want to get updated value of dropdownlist from database, but whenever I use EVAL, it throws the following error:

 'ddl' has a SelectedValue which is invalid because it does not exist in the list of items.

Parameter name: value
