For a project, I've created a web-part which derives from the ChartWebPart class (in order to set the data-source relatively).
SP:
SharePoint Server 2010 (Enterprise)
cs-file:
using System;
using System.ComponentModel;
using System.Web;
using System.Web.UI;
using System.Web.UI.DataVisualization.Charting;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using Microsoft.Office.Server.WebControls;
using Microsoft.SharePoint;
using Microsoft.SharePoint.WebControls;
namespace Cbs.PP.ProjectCosts.WebParts.ProjectExpensesChartWebPart
{
[Serializable()]
[ToolboxItemAttribute(false)]
public class ProjectExpensesChartWebPart : ChartWebPart
{
public ProjectExpensesChartWebPart()
{
}
protected override void CreateChildControls()
{
base.CreateChildControls();
}
}
}
Elements.xml:
<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/" >
<Module Name="ProjectExpensesChartWebPart" List="113" Url="_catalogs/wp">
<File Path="ProjectExpensesChartWebPart\ProjectExpensesChartWebPart.webpart"
Url="ProjectExpensesChartWebPart.webpart"
Type="GhostableInLibrary">
<Property Name="Group" Value="CBS" />
</File>
</Module>
</Elements>
Deploying the web-part and adding it to a site is no problem, but when I try to configure the webpart, it throws an exeption:
Type: SerializationException Message: The constructor which is needed for the deserialization of an object of the type "[...].ProjectExpensesChartWebPart" couldn't be found.*
*note: translation, since I have the german version of SP installed. Original: "Der für die Deserialisierung eines Objekts mit dem Typ "[...].ProjectExpensesChartWebPart" erforderliche Konstruktor wurde nicht gefunden."
I hope that someone has a clue, what's wrong here, or can at least point me in the right direction.
also, the Stacktrace:
