RegisterData problem

ihsany

hi,

i m using webreport and trying to register my business object like this;

protected void WebReport1_StartReport(object sender, EventArgs e)
{
//..
//Load Product List by Custom Business Objects
//
WebReport1.Report.Load(Server.MapPath("Products.frx"));
WebReport1.Report.RegisterData(ProductsList, "ProductsList");
WebReport1.Report.GetDataSource("ProductsList").Enabled = true;
((FastReport.DataBand)WebReport1.Report.FindObject("Data1")).DataSource = WebReport1.Report.GetDataSource("ProductsList");
((FastReport.DataBand)WebReport1.Report.FindObject("Data1")).DataSource.Enabled = true;
}

and html

<cc1:WebReport ID="WebReport1" runat="server" OnStartReport="WebReport1_StartReport" />

when i run this page, report is opening and there are 5 rows but all rows are blank.
but the products list has 5 rows with values.. and each list item has a custom object with public properties..

please help me..
thanks in advance..

Hello,

When you register a business object this way, FastReport actually does nothing. You should go the designer, "Data|Choose Report Data" menu and check the necessary datasources/fileds. Try to replace

WebReport1.Report.RegisterData(ProductsList, "ProductsList");

with

WebReport1.Report.RegisterData(ProductsList, "ProductsList", 3);

where 3 is max. nesting level of your business object.

thanks for your reply alex,

i tried also add an ObjectDataSource and chose it for DataSource but then, class public properties does not seem in report designer..

i m trying to make your said but something is going wrong.. How can i solve this problem? i attached a sample web site for this issue..

thanks for your helps..

The reason is simple: you've changed the datasource for the band, but didn't change the Text objects - Text2, Text4, Text6. They are still bound to old datasource - [ObjectDataSource1.Databound Col0]. You have to replace the text with something like this: [ProductList.ProductId]

hi alex,

i changed my approach last night.. Now, i only using ObjectDataSource and not other code..
My ObjectDataSource has public properties and a method for select. Select Method returns List<Products>
and everything goes OK.

Now i m looking for grouping. My product objects has a type property and i want to group report by type..
i hope, i can do this quickly and easily..
