Change XSD / XML dataset during runtime and display texts in field explorer

Question

Hi there,
I am changing the datasource of a report during runtime. Afterwards, I would like to change the texts of the fields appearing in the field explorer.
I tried:
CrystalDecisions.ReportAppServer.DataDefModel.XMLDataSetClass xmlDS =
new CrystalDecisions.ReportAppServer.DataDefModel.XMLDataSetClass();
byte[] xmlContent = reportContent.getXmlContent();
byte[] xsdContent = reportContent.getXsdContent();
CrystalDecisions.ReportAppServer.CommonObjectModel.ByteArray xmlData =
new CrystalDecisions.ReportAppServer.CommonObjectModel.ByteArray();
CrystalDecisions.ReportAppServer.CommonObjectModel.ByteArray xsdData =
new CrystalDecisions.ReportAppServer.CommonObjectModel.ByteArray();
xmlData.ByteArray = xmlContent;
xmlDS.XMLData = xmlData;
xsdData.ByteArray = xsdContent;
xmlDS.XMLSchema = xsdData;
rasDoc.DatabaseController.SetDataSource(xmlDS, "", "");
rasDoc.Database.Tables[0].Description = "POMMES";
for (int i = 0; i < rasDoc.DatabaseController.Database.Tables[0].DataFields.Count; i++)
rasDoc.Database.Tables[0].DataFields.Name = "TEST";
MessageBox.Show(rasDoc.Database.Tables[0].DataFields.Name);
rasDoc.Database.Tables[0].DataFields.HeadingText = "HOORAY";
rasDoc.Database.Tables[0].DataFields.Description = "NOPE";
MessageBox.Show(rasDoc.Database.Tables[0].DataFields.Description);
MessageBox.Show(rasDoc.Database.Tables[0].DataFields.HeadingText);
When running this, the message boxes include the right strings I set before but when this is done, the filed explorer still shows no changes. What am I doing wrong?
Also, I would like to change the field texts that are displayed in the field explorer. How can this be done?
Thanks,
Pascal

Answer 1

Also, I do not understand why I am not able to change the display of the fields in the filed explorer.
This coding does not change a bit, but why??
//preparation
string tableName = reportDataSet.Tables[0].TableName;
              // Get the table definition exactly like the definition of my own dataset.
              CrystalDecisions.ReportAppServer.DataDefModel.Table table = GetTable(tableName);
              table.ConnectionInfo = connectionInfo;
              //delete all existing tables if there are any
              foreach (CrystalDecisions.ReportAppServer.DataDefModel.Table oldTable in rasDoc.DatabaseController.Database.Tables)
                  rasDoc.DatabaseController.RemoveTable(oldTable.Name);
              //add my new table with the IDs of the XSD
              rasDoc.DatabaseController.AddTable(table, null);
              //now I want to change the displayed fields texts
              CrystalDecisions.ReportAppServer.DataDefModel.Tables modifyTables =
                  rasDoc.DatabaseController.Database.Tables;
              CrystalDecisions.ReportAppServer.DataDefModel.Table myTable =
                  (CrystalDecisions.ReportAppServer.DataDefModel.Table)modifyTables[0];
              Fields fields = myTable.DataFields;
              for (int i = 0; i < fields.Count; i++)
                  ISCRField field = fields<i>;
                  ResultFieldController resultFieldController =
                     rasDoc.DataDefController.ResultFieldController;
                  try
                      resultFieldController.Remove(field);
                      string sText = "";
                      sText = "Bäschreibung" + i.ToString();
                      field.Description = new string(sText.ToCharArray());
                      sText = "Häding" + i.ToString();
                      field.HeadingText = new string(sText.ToCharArray());
                      //sText = "Näme" + i.ToString();
                      //field.Name = new string(sText.ToCharArray());
                      resultFieldController.Add(-1, field);
                  catch (Exception exp)
                      MessageBox.Show(exp.Message);
I am completely stuck.
Thanks for any help.
