The gridview control's interface does not enable the user to filter on a null or empty date in a date column. But a null date is a valid entry in a date column. Is there a way to enable filtering (for an end user) for a null date in a date field. If not could this be added to the list of feature requests for future releases.

I would like to let an end user filter on a grouped column. There appears to be on way to do this. If this is correct and it currently cannot be done, can this be added as a feature request for future releases. This could be achieved by displaying a filter text box to the right of each grouped column header label.

With both these issues I can achieve the desired results by adding extra controls to a form and programatically implementing the effect I want, but I would like the features built into the telerik gridview control.

Hello Barry,

Thank you for these suggestions.

1. Currently there is no way to filter on a null value in RadGridView. We will add this feature in our TODO list and it will be implemented in one of our next releases.

2. You can set the ShowGroupedColumns property to true. This way you will be able to filter grouped columns. Consider the code snippet below:

this.radGridView1.MasterGridViewTemplate.ShowGroupedColumns = true

We will consider your suggestion about adding text boxes to the right side of each group item.

I have added points to your account for the suggestions.

Don't hesitate to contact us if you have any other questions.

Best wishes,

Jack - is there any way to subscribe to certain updates / fixes?

The filter function on datetime columns which are nullable is pretty important to us - so we want to be sure to update as soon as its released.

Best regards,

Mikkel

Hi Mikkel,

Right now we offer only a RSS feed which sends news on when a new version of our tools is available, plus all changes that were mage. You can subscribe to it here: Release history. We also announce all new versions in our monthly newsletter.

We are working on a public issue tracker which will give you the functionality you are after - to get updates on a specific item only. The issue tracker is expected in a couple of months.
