I'm using Sharepoint List Filter to filter values from a Sharepoint List. However, one option is missing for the user and that's the ability to show everything (in other words, disengage the filter) It seems like I cannot inherit SpListFilterWebPart since it's sealed. Thanks

Bump. Does anyone know the answer to this?

Hi, In the "Advanced Filter Options" section in toolpane (Edit --> Modify Shared Web Part) for List Filter, select "Allow multiple selections" checkbox. This way users will have checkbox option instead of radio button for selecting value and if they will uncheck all the check box, all items would be visible. Hope this helps. Regards.

Thank you, this option is familiar to me but it is not available since the filter is connected to a list view. Is there no way to inherit this web part?

Hi, Remove the connection between filter and list view web part and after making necessay changes in "Advanced Filter Options", again create connection between filter and list view web part. Regards.
