[Solved] Sorting Converted Data

[Seo]

Hi,
I want to sort column Data as converted Data type.

I  am getting Data via WCF RIA Services, and convert Data string type  into number type using a converter.

and I want to sort these Data  as NUMBER  TYPE(Converted Data Type) with column header click event,

but  sorting is not working properly.

i think , it is sorted as String Data Type(Original DataType).

can you teach me how to sort Data as converted data type?

i attach a file.

thanks.

Hello Seo,

With our latest release we have extended the functionality of the sort descriptors.
A way to perform complex sorting  is demonstrated in this blog post. The example with the sort descriptor demonstrated there can be easily modified to use the converter.

This code can be executed within the Sorting event handler of RadGridView.

In case you need a working example of such implementation with the above  mentioned approach - just let me know are you trying to sort programmatically by adding sort descriptors  or you need sorting by the converted value when the user clicks the column  header.

All the best,
Pavel Pavlov

Hello, Pavel

Thank you for your reply.
I need sorting by the converted value when the user clicks the column header.

and I have one thing need to know.
that is:
when the user clicks the column  header,
is it always sorting the original value type?
is there no way(sorting the converted value type) if i set specific property?

I've try to the example what you taught me, 
but actually I don't  understand it well now.
I try it more...

thanks.
