Migration from ASP .Net 1.1 to 4.0

I have migrated the application in asp .net 1.1 to 4.0 successfully using wizard.
But i am facing some issues in follwoing senario

Application uses one dll which contains 2 overloaded methods as below

public static UltraWebGrid EncodeDatagrid(Infragistics.WebUI.UltraWebGrid.UltraWebGrid dg)
{
   return dg;}

public static DataGrid EncodeDatagrid(DataGrid dg)
{
   return dg;
}

when i am calling EnocdeDatagrid in the application as below

Protected WithEvents grdArea As System.Web.UI.WebControls.DataGrid
EncodeDatagrid(grdArea)

getting the following compile time error

"Reference required to assembly 'Infragistics.WebUI.UltraWebGrid.v5.1, Version=5.1.20051.37, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb' containing the type 'Infragistics.WebUI.UltraWebGrid.UltraWebGrid'. Add one to your project. C:\Inetpub\wwwroot\AphelionDotNet\Lockers\AddArea.aspx.vb"

So what's your question?

Re: Migration from ASP .Net 1.1 to 4.0

Why we need the reference of infragistic dll in VS 2010 if we are not calling the function which is having the infragistic control as a parameter? This reference is not required in the VS 2003.

Re: Migration from ASP .Net 1.1 to 4.0

You need a reference because your code is using it. It does not matter that you never call that function - Visual Studio cannot figure out what functions are not called. Hence the reference is required.

Re: Migration from ASP .Net 1.1 to 4.0

With the same senario it does not required the reference in the VS 2003 why this is so?

Also if I am not at all calling the EncodeDatagrid() method then it does not required the reference in VS 2010

Re: Migration from ASP .Net 1.1 to 4.0

The last time I saw VS 2003 was about 5 years ago, so it's difficult to say why reference is not required there.

HOWEVER, if you don't call this method, can I ask what is it doing in your code? Just comment it out, if you don't call it - you don't need it. Problem solved.

Re: Migration from ASP .Net 1.1 to 4.0

I am calling 1 of the overloaded method from my code as i shown in the code given above.

Re: Migration from ASP .Net 1.1 to 4.0

OK, do the following:

//public static UltraWebGrid EncodeDatagrid(Infragistics.WebUI.UltraWebGrid.UltraWebGrid dg)
//{
//   return dg;}

public static DataGrid EncodeDatagrid(DataGrid dg)
{
   return dg;
}

This will solve your problem with a reference.
