Custom filter (dropdown + checkbox) populated from XML file

[vlad]

Hello,

I have a simple problem that seems really hard to solve (for me !) :

To make it simple, imagine that I have a RadGrid displaying a list of customers. One of my columns ('language') can contain only predefined values stored in XML file.

For example:

<?xml version="1.0" encoding="utf-8" ?>
<Items>
  <Item Text="English" Value="0" />
  <Item Text="German" Value="1" />
  <Item Text="French" Value="2" />
  <Item Text="Italien" Value="3" />
  <Item Text="Chinese" Value="4" />
  <Item Text="Russian" Value="5" />
  <Item Text="Other" Value="6" />
</Items>

If I use GridDropDownColumn, I can display data, no problem. But I need to setup a custom filter.

I need a dropdown control (like MS DropDownList or RadComboBox) populated with my XML file, where user can chosse one OR MORE languages he wants to display (for example German AND French). So this control has to implement checkboxes, for example.

It looks like a very common scenario. So I'm really surprised that it seems so hard to implement. I can't get it work ... Can anybody give me a simple working example that I can adapt ?

Thanks a lot !

Hello Vlad,

Check out the following code library submission which illustrates on how to implement a RadComboBox supporting multi-selection with checkboxes. This should surely help you to achieve your requirement.
