[Solved] RadGrid Sorting Issue

[Wai Chiu Lau]

Hi,

I have a problem when sorting template columns containing fields that are objects.

I have custom collection ContactList with ContactInfo objects. One of the property of ContactInfo is Owner which is an object of type OwnerType. This object has ToString() method so the column is filled with the data, so that is no problem. When I sort this column the grid just goes blank!

I would really appreciate help.

Hi Tahir ,

How the grid is bound in your case? Do you use NeedDataSource or ObjectDataSource?

Kind regards,

Hi,

Thanks for your reply. I am not using either. I use something like:

gvw.DataSource = ContactList.Load().List
gvw.DataBind()

Hello Tahir,

Automatic sorting can be achieved only with advanced data-binding otherwise you should handle SortCommand, provide DataSource and DataBind() the grid again exaclty in the same way as with MS DataGrid or MS GridView. More info you can find here:

Hello Vlad,

Yes I am doing exactly that, handling the SortCommand event and providing DataSource and calling DataBind(). For simple columns it works fine however for a column (property of object) that is a custom object/class, then it fails.

Hi Wai Chiu Lau,

You can switch to Advanced Databinding. Please, find an example of RadGrid bound to sub-objects here.
