Using built in filtering (from column headers) with DomainDataSource

[Matt Greer]

It seems like the RadGridView works with the DomainDataSource well for the most part. If I sort on a column for example, this causes the data to be sorted correctly with paging taken into account (ie the entire datasource is sorted, instead of just the page I am currently on).

But this is not true with the built in filtering functionality. If I click the filter icon on a column header, and pick a filter, it only filters the current data in the current page. What I want it to do is filter the entire datasource and repage/load the entire grid with the new filter. Effectively if I assigned a FilterDescriptor to the DDS myself.

Is this possible? Can I get the grid to do this for me, or can I intercept the filtering functionality and filter the DDS myself?

Hello Matt Greer,

You have three options.

1. Implement server-side filtering like this blog post describes.

2. Translate all filtering that occurs in the grid to DomainDataSource FilterDescriptors, like this example demonstrates.

3. Turn the grid filtering off and throw RadDataFilter in the whole picture. RadDataFilter can directly filter the DomainDataSource like demonstrated in this example. RadGridView will be simply bound to the DDS and will have absolutely no clue that RadDataFilter is actually filtering the DDS.

I hope this helps.

Thank you, those are good choices to work with.
