Hello Jingying Wu,

You can clear grid FilterDescriptors.

All the best,

I tried that already and it simply clears out the entire grid data.
I just opened a ticket (Your ticket ID is : 237010 ) with the screenshots, so that you can see what i'm seeing.
thanks,

Hi Jingying Wu,

I cannot reproduce the problem that you are describing in neither 2009.1.526 nor 2009.2.701. I have attached two project (526 and 701) where you can find a button that clears the filtering without side effects.

The only possible cause of the data loss that you are describing is if the FieldDescriptors collection is cleared instead of the FilterDescriptors one.

Since we were unable to reproduce the problem would you be so kind to send us an application which can be used to simulate the data loss?

Sincerely yours,

I'm using 2009.1.526.
I can repro the same issue in your attached application (clearfilter526.zip)

Repro steps:
1) Click Filter on Subject by checking (Cats are cool)
2) See that it's filtered to show only "Cats are cool"
3) Click button (Clear Filter)
4) Now Filter on Subject by checking (Mice are cool). (Uncheck all others)

Expected Results:
Filter works on Mice are cool

Actual Results:
Filter no longer works after clicking (Clear Filter)

Hi,
is it possible that I have the same issue in a current control build?

Scenario:
1. I have a grid with  the default filtering
2. I have a 'clear filter' button, which should reset all filters
3. After a click on the button, the filter indicator is now grey (aka. 0 filters set)
4. If I open the column filter dialog, the value by 'contains' is still set.

Do you have any idea how to 'fix' it?

Thanks!
