How to bind nested collection

[ali zubair]

Hi All,

I have struck with very serious problem while using Rad grid.

Issue is my web Method returns a collection (Student Collection). i have bounded that collection to rad grid through javascript like

IndendedProgramGrid = $find("<%= rgIndendedProgram.ClientID %>").get_masterTableView();
IndendedProgramGrid.set_dataSource(result[0].ObjStudentProgramsCollection);
IndendedProgramGrid.dataBind();

In "ObjStudentProgramsCollection" have some direct colums like "ID" which is bounded very successfully with grid.But this collection also have another collection in it. Like "ObjStudentProgramsCollection[0].Cources.CoucseName". Now i want to bind course name to rad grid colum..

How can i bind this.
In asp data list i simply use following code and works properly. How can i do this in Rad Grid>????
 <%#Eval("Courses.courseName")%>

Please help.......

Hello Ali,

RadGrid cannot bind out of the box to nested properties. However you can  handler OnRowDataBound client event and populate the cell manually as demonstrated on the snippet bellow:

1.function rowDataBound(sender, args)
2.            {
3.                args.get_item().get_cell("Column_UniqueName").innerHTML = args.get_dataItem().Nested.Text;
4.            }

Best wishes,
