Web Part Error: Unhandled exception was thrown by the sandboxed code wrapper's Execute method in the partial trust app domain: An unexpected error has occurred.

namespace DemoProject.HelloWorldWebPart 
{ 
    [ToolboxItemAttribute(false)] 
    public class HelloWorldWebPart : WebPart 
    { 
     protected override void CreateChildControls() 
     { 
      //Label lblHelloWorld = new Label(); 
      //lblHelloWorld.Text = "Hello World"; 
      //this.Controls.Add(lblHelloWorld); 
      //const string DATASOURCEID = "gridDS"; 

      ObjectDataSource gridDS = new ObjectDataSource(); 
      gridDS.ID = "gridDS"; 
      gridDS.SelectMethod = "SelectData"; 
      gridDS.TypeName = this.GetType().AssemblyQualifiedName; 
      gridDS.ObjectCreating += new ObjectDataSourceObjectEventHandler(gridDS_ObjectCreating); 
      this.Controls.Add(gridDS); 

      // Instantiating Sharepoint GridView object and assigning properties to it 
      SPGridView spgvStudentList = new SPGridView(); 
      spgvStudentList.ID = "spgvStudentList"; 
      spgvStudentList.DataSourceID = gridDS.ID; 
      spgvStudentList.AutoGenerateColumns = false; 
      spgvStudentList.AllowPaging = true; 
      spgvStudentList.PageSize = 5; 
      spgvStudentList.AllowSorting = true; 
      this.Controls.Add(spgvStudentList); 

      SPGridViewPager pager = new SPGridViewPager(); 
      pager.GridViewId = spgvStudentList.ID; 
      this.Controls.Add(pager); 
     } 
     public DataTable SelectData() 
     { 
      // Creating a datasource object for databinding the sharepoint gridview 
      DataTable dataSource = new DataTable(); 

      dataSource.Columns.Add("ID"); 
      dataSource.Columns.Add("Name"); 
      dataSource.Columns.Add("Region"); 
      dataSource.Columns.Add("Total Sales"); 

      dataSource.Rows.Add(1, "J. Smith", "Europe", 10000); 
      dataSource.Rows.Add(2, "J. Smith", "North America", 15000); 
      dataSource.Rows.Add(3, "J. Smith", "Asia", 5000); 
      dataSource.Rows.Add(4, "S. Jones", "Europe", 7000); 
      dataSource.Rows.Add(5, "S. Jones", "North America", 30000); 
      dataSource.Rows.Add(6, "S. Jones", "Asia", 8700); 
      dataSource.Rows.Add(7, "W. Nguyen", "Europe", 3000); 
      dataSource.Rows.Add(8, "W. Nguyen", "North America", 50000); 
      dataSource.Rows.Add(9, "W. Nguyen", "Asia", 25000); 

      return dataSource; 
     } 

     private void gridDS_ObjectCreating(object sender, ObjectDataSourceEventArgs e) 
     { 
      e.ObjectInstance = this; 
     } 
    } 
} 

Quelqu'un peut-il me suggérer ce que je fais mal ici? Merci et salutations Mac

Answer 1

Eh bien je l'ai eu, je l'ai utilisé des solutions sanboxed et appels de processus de travail en sandbox sont limitées à utiliser plusieurs classes et méthodes. Malheureusement, Microsoft.Sharepoint.WebControls est également l'une des classes. nous sommes limités à l'utilisation des contrôles ASP.Net uniquement. Je l'ai changé pour Farm Solutions et ça marche bien.
