DataSet binding problem

I use the following code to bind a DataSet:
StiReport r = new StiReport();
r.RegData(dsData.DataSetName, dsData);
r.Dictionary.ImportXMLSchema(dsData);
r.Dictionary.Synchronize();
designer.Design(r);
but it seems that no connection to DataSet can be made, I have the schema and can design the report, but no preview. And the DataSet is crossed as the attached image.

Hello,
Please use following code:
Code: Select all
StiReport r = new StiReport();
r.RegData(dsData.DataSetName, dsData);
r.Dictionary.Synchronize();
designer.Design(r);
Thank you.

Thank you very much for your prompt reply.
I changed the code as you advised, but the problem still persists:
DataSet dataset = dbm.Query("SELECT Alias, Fullname FROM users");
StiReport r = new StiReport();
r.RegData(dataset.DataSetName, dataset);
r.Dictionary.Synchronize();
StiWebDesigner1.Design(r);

Hello,
You must also add database to dictionary. Please use the following code:
Code: Select all
string connString = "SELECT Alias, Fullname FROM users";
StiSqlDatabase database = new StiSqlDatabase(dataset.DataSetName, connString);
report.Dictionary.Databases.Clear();
report.Dictionary.Databases.Add(database);
Thank you.

Hi,
Now, the dataset is not crossed anymore and I can drag-drop the fields to my report. But the report preview does not show any data, and when I try to use a StiWebViewer to show the saved report, it says:
"Format of the initialization string does not conform to specification starting at index 0."
and shows the following line as the error line:
StiWebViewer1.Report = r;
here is the code I am using to invoke the designer
dset = dbm.Query("SELECT Alias, Fullname FROM users");
dset.Tables[0].TableName = "users";
StiReport r = new StiReport();
string connString = "SELECT Alias, Fullname FROM users";
StiSqlDatabase database = new StiSqlDatabase(dset.DataSetName, connString);
r.Dictionary.Databases.Clear();
r.Dictionary.Databases.Add(database);
r.RegData(dset.DataSetName, dset);
r.Dictionary.Synchronize();
StiWebDesigner1.Design(r);
and to show the report:
dset = dbm.Query("SELECT Alias, Fullname FROM users");
dset.Tables[0].Rows.Add("Ali", "Ali");
dset.Tables[0].TableName = "users";
StiReport r = new StiReport();
r.Load("c:\\Users\\bakhtiari\\Desktop\\1.mrt");
string connString = "SELECT Alias, Fullname FROM users";
StiSqlDatabase database = new StiSqlDatabase(dset.DataSetName, connString);
r.Dictionary.Databases.Clear();
r.Dictionary.Databases.Add(database);
r.RegData(dset.DataSetName, dset);
r.Dictionary.Synchronize();
StiWebViewer1.Report = r;
r.Render(true);
I have added that "dset.Tables[0].TableName = "users";" lines to see if it may solve the problem, but no change.
Besides, are you sure it is a good idea to use a SELECT command here? I am going to use it as the report engine for an ERP, and the main application populates a dataset and sends it to me to create reports. The dataset I am given can be quite complex and I don't know how i should create a SELECT command to represent all the relations in it!

Hello,
"Format of the initialization string does not conform to specification starting at index 0."
Please send us the full error stack.
For the viewer you need only register the data, creating a connection is not necessary. It is necessary only for the report designer, because the report designer stores only the data schema, the data are not transferred. Also, for these purposes, the web designer has a special GetPreviewDataSet event, where you can register data for preview.
r.Render(true);
Not necessary to render a report after the appropriation its to the viewer, as viewer knows how to do it myself.
Thank you.

Hi,
I added the "GetPreviewDataSet" event, and set "e.PreviewDataSet" to my dataset, but still the preview is empty.

Hello,
I'm sorry, it is my mistake. In the connection string parameter you must set your connection properties to your database, not to a query for it. For example:
Code: Select all
connString = "Data Source=127.0.0.1;Initial Catalog=master;Integrated Security=True"
If, after fixing the code we did, the problem still exist, please send us aspx and cs files for analysis.
Thank you.

Hello!
I have been reading very carefully this topic because I´ve the same problem.
My steps are the following:
First I Call a designer, design the report in the web browser but can not get to preview, what is wrong??
I tried to do the same locally and it works perfectly.
my code is:
Code: Select all
StiReport re= new StiReport();
DataSet data= new DataSet();
bussinesAD bussines= new bussinesAD();
data= bussines.getBussinesID(2);
re.RegData(data);
string connString = "Data Source=.\\SQLEXPRESS;AttachDbFilename=C:\\Proyects Rodrigo\\GesRes.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True";
StiSqlDatabase database = new StiSqlDatabase(data.DataSetName,connString);
re.Dictionary.Databases.Clear();
re.Dictionary.Databases.Add(database);
re.Dictionary.Synchronize();
StiWebDesigner1.Design(re);
*Edited: informe -> re; I wrote it wrong here, sorry*
Thank you for your help!
