custom web parts

[looksharp123]

Hi there
Is it a difficult or straightforward thing to integrate Chart FX components into custom web parts (i.e. web parts created using the WebPartManager control in VS 2005 for a straightforward ASP.NET application, not one based on the Sharepoint platform)?
I can only find information related to Sharepoint, but we don't develop this way.
I'd appreciate any comments.
Best regards

Like any Web Control Chart FX can be added as a Web Part.

I don't know exactly what kind of functionality are you looking for but if you care to elaborate maybe I can point you in the right direction.

We wrapped it in a server control and use the generic webpart to load it and it works fine.  The one thing that we have not been able to get working is the Autosave Autoload; that feature will go into an endless loop the first time the part is added to the manager.

Are you rendering as an image or as a .NET Client?

If you are rendering as an image. Are you handling the Personalized event? What are you doing in it?

We're using .NET.  Actually some tidbits I picked up in other threads helped me get autosave and autoload working.  UseCallbacksForEvents seemed to be key. 

BTW We're saving the personalize bytes in a web part personalizable property rather than the profile as the example docs show.  This is all done in the server control wrapper I mentioned.

[Personalizable(), WebBrowsable]

public Byte[] ChartPersonalization

{

  get { return btChartPersonalization; }

  set { try { btChartPersonalization = value; } catch (Exception) { } }

}

 

... 

// Save

if (e.Stream != null)

{

  Byte[] btChart = new Byte[e.Stream.Length];

  e.Stream.Read(btChart, 0, btChart.Length);

  e.Stream.Close();

 

  // The web part property will be saved in personalization

  ChartPersonalization = btChart;

}

 

 

// Read it back...

if (btChartPersonalization != null && btChartPersonalization.Length > 0)

{

  e.Stream = new System.IO.MemoryStream(btChartPersonalization);

}

Excellent, looks like you have it under control now.
