For example how you were able to rename RechnungenBO.cs to RechnungenReportBO.cs without breaking everything ? I will try to create it from scratch again. I really need to know the way of getting there. I used CustomBuisnessBindingSource to create the BBS and BO('s) within the ReportBinding namespace. Thanks alot for your help.

Had to delete the instance of your RechungenBBS from the form, as there was some error there, I guess with namespaces or such. Also repaired some code and inheritance of BO, and it looks like working now: Attachments ReportSS2.zip (118 views, 3.00 MB)

Group: Forum Members Posts: 141, Visits: 263	Ivan George Borges (12/08/2008) It looks like you forgot to override the AreCustomerDescriptorsEvaluated property: Private Shared _AreCustomDescriptorsEvaluated As Boolean = False /// <summary> /// Determine if the custom descriptors are going to be evaluated /// </summary> /// <remarks></remarks> protected override bool AreCustomDescriptorsEvaluated { get { //-- Establish Locals bool r = _AreCustomDescriptorsEvaluated; //-- Do not eval the desciptors again _AreCustomDescriptorsEvaluated = true; //-- Return results return r; } } Actually i allready have that: namespace ReportSS2.ReportBinding { public class RechnungenBO : ReportSS2.RechnungenBO { #region Private Fields private static bool _AreCustomDescriptorsEvaluated = false; private static RechpositionenBBS _Rechpositionen = new RechpositionenBBS(); #endregion #region Protected Methods /// <summary> /// Determine if the custom descriptors are going to be evaluated /// </summary> /// <remarks></remarks> protected override bool AreCustomDescriptorsEvaluated { get { //-- Establish Locals bool r = _AreCustomDescriptorsEvaluated; //-- Do not eval the desciptors again _AreCustomDescriptorsEvaluated = true; //-- Return results return r; } }

Group: Forum Members Posts: 141, Visits: 263	i noticed i build my test project different from the samples, so i created a new one which is now in-line to how the samples were build: The one with the red underline is where i put the custom property for Rechpositionen. Now when i run the project, i get a null-reference exception at the line: r.Add(new ReflectionPropertyDescriptor("Rechpositionen", typeof(RechpositionenBO))); "The Object reference not set to an instance of an object." I have uploaded the new source code here: http://www.ready3.net/ReportSS2.zip

One way of doing it is to make your BBS show up in the toolbox and drop it on the form. For that, add the ToolboxItem attribute to your BBS code: Then, rebuild your project, which will make your BBS appear in the toolbox. Drop it on your form and you will be able to choose it from the ReportManager Data Sources list:
