Help with the NeedDatasource event.

[Emil Eriksson]

I dont know what I have done wrong. I have a chart, the chart needs a datasource. This is my NeedDataSource-method

private

 

void companyBooking_NeedDataSource(object sender, System.EventArgs e)

 

{

Telerik.Reporting.Processing.

Chart companyBookingChart = sender as Telerik.Reporting.Processing.Chart;

 

companyBookingChart.DataSource =

this.bokadoktornDataSetTableAdapter1.GetData();

 

}

In the InitializeComponent()-method I have this eventHandler.
this.companyBookingChart.NeedDataSource += new System.EventHandler(this.companyBooking_NeedDataSource);

This is my database-sqlquery, (Works fine)

SELECT YEAR(BookedDate) AS Year, MONTH(BookedDate) AS Month, CONCAT(u.FirstName, ' ', u.LastName) AS FullName, Count(*) AS NoOfBookings
FROM         Bookings b
INNER JOIN Users u ON u.Id = b.BookedById
INNER JOIN CompanyUsers cu ON cu.Id = u.Id
WHERE cu.CompanyId = 1
GROUP BY u.Id, MONTH(BookedDate), YEAR(BookedDate)
ORDER BY NoOfBookings DESC;

When I preview my report nothing happends. I dont know why, everything worked fine until I added my chart. Is it something wrong with my NeedDataSource-method.

Thanks
/Emil

Hello Emil Eriksson,

From what you have sent the problem is not in this code. Please check the Output window for any exceptions and try to debug the application to make sure that everything is properly initialized and called.
