Binding a collection of collections
-
Consider a Collections of Organisations and let that collectionObject be called collectionOrg. Each organisation Object in the collection have name, address and an object called countryObject which has country Id and country Name. I want to bind this collectionOrg to a datagrid. Code for this is OrgDataGrid.DataSource = collectionOrg; OrgDataGrid.DataBind(); and in the html part to bind this property to the But as this CountryObj.Name gives an error. What should I do to handle this error. Thanks in advance With Thanks and Regards Anand Ignorance is Bliss

Hi there, Why don't you provide a little more information about the error and sample code instead of letting people diagnose the problem of your sample code just from fews words "gives an error ..."?
It gives an error unable to find property "Name" if i provide "Name" as datatextfield which is correct as the collection directly donot have Name only Collection.Country.Name is available. Even "Country.Name" gives the same error cannot find property. the bound column to datagrid is like as follows when i set datafield as name or country.name it gives error cannot find property anyway Thanks for the reply Not everything that can be counted counts, and not everything that counts can be counted -- modified at 11:45 Wednesday 28th September, 2005

Because, you bind a property (Name) of a member (Country) of an item (Organization) in the collection, you should not use the bound column as the DataTextField requires you to specify a member of the Organization object. In this case, you can use a template column, and provide a data binding expression using the DataBinder class.
