[Solved] GridViewComboBoxColumn

[Phillip Garrett]

Hi,

I've followed your documentation on GridViewComboBoxColumn here:
http://www.telerik.com/help/silverlight/radgridview-columns-column-types-combobox-column.html

This works, however I would like to filter, sort and group by DisplayMemberPath value rather than the DataMemberBinding value.

In your example clicking filter on the Country column header would filter on CountryId (a collection of numbers). How do I get the filter to pick up the DisplayMemberPath values (a collection of strings)?

Thank You
Phill

Hi Phillip Garrett,

Indeed for the time being that is the recommended way of filtering a GridViewComboBoxColumn. Another possible approach may be to use the DistinctValuesLoading and Filtering events of the grid and set the values to be shown inside the UI of the filter and those the filtering to be performed on. You can read a bit more about this workaround in this forum thread.
However, I would suggest you to use the one described in the blog post.

Thanks,

Does this mean there is a GridViewComboBoxColumn filtering improvement in the pipe-line?
(i.e. to avoid custom filtering controls or event handling)

Hi Phillip Garrett,

The recommended mechanism for filtering a GridViewComboBoxColumn represents mainly forcing that column to be filtered by means of external additional code. However, implementing that functionality is in our to-do list and we are investigating the best possible approach for including it in the grid.
