I have a report that contains a number of fields, and a table control. My data source is a list of "user" data objects, each of which in turn contains a list of "phone number" objects.

I create the report programmatically, and then assign my user list to its DataSource property. So far so good. Now what is the correct way to get each user's phone number list into the table? Should this be done within the detail section itemdatabound event handler? This is the approach I tried initially, and I'm having some problems with it, so I wanted to confirm best practices before proceeding further.

Hi Mark,

The DataSource of the report is a separate thing from the DataSource of the table item itself, which can be considered as separate "data" region. If you want to bind it programmatically, you should use its NeedDataSource event i.e.:

table1.NeedDataSource += new EventHandler(table1_NeedDataSource);

private
 void table1_NeedDataSource(object sender, EventArgs e) 
        { 
             string sql = @"SELECT Name, ProductNumber FROM Production.Product"
         string connectionString = 
           "Data Source=(local)\\SQLEXPRESS2005;Initial Catalog=AdventureWorks;Integrated Security=True"
         SqlDataAdapter adapter = new SqlDataAdapter(sql, connectionString); 
         DataSet dataSet = new DataSet(); 
         adapter.Fill(dataSet); 
             
            Telerik.Reporting.Processing.Table procTable = (Telerik.Reporting.Processing.Table)sender; 
            procTable.DataSource = dataSet; 
        } 

If you're providing the data directly to the definition table item, then you can setup one table at design time and see the generated code for it in the InitializeComponent() method for sample code snippet.

Hi farooq,

I am not sure I understand your scenario. Do you use any data source components or the DataTable objects is passed directly to the report? Have you set any filter expressions? I have attached two sample reports illustrating NeedDataSource to pass data and objectDatasource component.

If you need help on this, elaborate on your report structure, data, databinding and settings.

All the best,
Stef
