Creating a crystal report from a dataset
Hi
I have created a blank Crystal report called test.rpt.
I would like to manually add the information from a dataset to the report.
The report is loaded into Crystal Report Viewer.
The below code works in adding the report to the viewer but how would I connect my dataset to it?
I think I am close, just need help with the final display.
Thanks

private void rptBrowser_Load(object sender, EventArgs e)
{
// Create new DataSet
mydb thedb = new mydb();
SqlDataAdapter myds = null;
string _sql = "select LogName, Firstname, Lastname from sysUser";
myds = thedb.myDataAdapter(_sql);
ReportDocument cryRpt = new ReportDocument();
cryRpt.Load(myglobal_properties.FP1 + "test.rpt");
rptView.ReportSource = cryRpt;
rptView.Refresh();
}

Greatsubash - I am not sure which article I am looking at
mimcc - I don't know VB and I am using VS2008. This article assumes you have a dataset created but I am trying to create one programically and link it to the Crystal Report.
Any help is always appreciated.
I tried adding the line cryRpt.SetDataSource(myds)
However, I am now getting a 'the data source object is invalid error message.
1. What am I doing wrong in my code
2. I have attached my code for creating a dataset below. Is there any way to see in the watch list what is contained in the dataset or a way to browse a dataset. There is no errors in creating the dataset but I would like to see if it contains any information.

SqlDataAdapter thisAdapter = null;
if (!isConnected)
return thisAdapter;
SqlCommand thisCommand = new SqlCommand (sql,thisConnection );
myds = new DataSet();
try
{
thisCommand.CommandText = sql;
thisAdapter = new SqlDataAdapter(thisCommand );
thisAdapter.Fill(myds, "DataTables");
//Return result
return thisAdapter;
}
catch (Exception ex)
{
string _error = ex.Message;
return thisAdapter;
}
finally
{
thisCommand.Dispose();
thisCommand = null;
}
His creates the dataset in the program trhen passes it to the report.

Thanks Mimcc
I am running VS2008 so when I downloaded sample it was converted into VS2008. When I try to run the report I get a load error.
I am really looking for a solution for my code. Is there any way you are able to help me with that? or anyone else?

Did you check for data in your dataset? Throw a datagridview on your form and set the datasource to your table in your dataset...make sure you have the data you expect....

elmbrook, could you please tell me what does rptView mean in the code???
And the second question:
Is your DataSet is displayed in your Report after the final code?

rptView is my form that displays the Crystal Report Viewer.
You have to connect the Dataset to the report first using the Database Expert, drop the fields in the report and then the information is displayed in the report.
