Hi. I'm using the OperationVisibility event of the ASPxFilterControl to customise the list of operators available for each column. I notice under ClauseType there are a variety of predefined date filters like IsToday, IsTomorrow, IsEarlierThisWeek, however I can't make them visible. I presume this is because they're used by the WinForms controls instead, but is there any reason they couldn't be made available in the ASPxFilterControl as well?
Regards,
Stuart.
Hi,
These operations weren't implemented in ASPxFilterControl, so you can't make them visible. However, ASPxGridView can work with these criteria, so you can apply this filter using the ASPxGridView.FilterExpression Property. Let me know if you have further questions.
This functionality is sorely needed. Many of our users are asking for this. We allow our user to save grid layout. They can later pick it from a list and restore the layout as they had it. However, the need to be able to filter date fields based on relative dates. They need to be able to say [SomeDateField] >= TODAY. And, be able to save that as grid's layout for later retrieval. Please provide a work-around on how this can be done. Also, besides being able to use relative dates, they need to retain the ability to filter using absolute values.
If the grid control would allow to compare fields, such as [Field1] [Comparison] [Field2], then I could add a field called [Today] into the grid and let users compare to that field. But, this option is also missing. Please provide a usable work-around.

Please take note of a similar functionality implemented in version 15.2 in the context of the following feature: ASPxFilterControl - Support predefined operations for date columns
