composite filter

[David Ocasio]

if i add a filterdescriptor derectily to a radgridview attached to a raddatapager and a raddomaindatasource
the raddomaindatasource (set to autoload) does a load automatically

if i add a compositefilter directly to a radgridview attached to a raddatapager and a raddomaindatasource
the raddomaindatasource (set to autoload) also does a load automatically

but if i add a filterdescriptor to a compositefilter that is already attached to the radgridview a load is not performed

this seems inconsistenet to me.

thanks

Hi,

 I have tested the described scenario. Once I changed the FilterDescriptors in the already attached CompositeFilterDescriptor the GridView was filtered again. Generally as long as something changes, be it something very small or absolutely everything, the filtering expression is rebuilt from scratch and re-executed against the source collection in order to get the new fresh view of the data.

May I ask you to share how do you define the filter in both the cases and when do you change it?

I an not saying the radgridview is not filtering, in fact it is.
Rather no new load from the datasource(ria in my case) is triggered.

so it goes something like this

add a filterdescriptor to the grid
domaindata source does load

add a compositefilter to the grid
domaindata source does load

add a compositefilter to the grid
domaindata source does load
add a filterdescriptor to compositefilter
domaindataa source does not load
radgridview filters locally.

thats the behavior i observed

thanks

Hello,

 Thank you for the clarifications. We were able to encounter the behaviour as you have described it. 

We will need to discuss whether this behaviour should be changed. I will update the thread once I have more relevant information to share.

Hello,

In regard to our previous conversation, I would recommend you to work with the FilterDescriptors of the RadDomainDataSource directly. You could check this online demo for an example.

I hope this will work good for your scenario.

All the best,

thanks

yes i rewrote it as just filterdescriptors instead of using the composite
this works for my current need.
but i could forsee where in a more complex situation the composite filter might be advantageous.

Hello,

We will investigate this issue.

But when you add the descriptors directly to RadDomainDataSource you should be able to use any number of nested CompositeFilterDescriptors -- is that not the case? Can you please try this -- do exactly the same but do not add the CompositeFilterDescriptor to the grid but to the RadDomainDataSource.FilterDescriptors. Isn't this working properly?

i see what your saying

add the compositedescriptors to the domaindatasource instead of the gridview

i will investigate
