Disable button when SelectedDate is null

Hello,
I've got a DateTimePicker and a Button inside a WPF / Caliburn Micro project... I wish to disable the button when the user doesn't select a date... but there's no set of my property to null since the Validator detects that there's no datetime selected... how can I do that?
Thanks

Paolo

How to fix the gap between two x-Axis values.

Hi,
I have a chart, which works on some filter selection of dates.

User can select atmost 12 dates to be displayed on the chart. It has grid at the bottom which is aligned to x-axis points of the chart (see the attached image.)

Now when user select the less number of dates say 2 or 6, the gap between the two dates on x-axis increases, as it has more space available, which is now not alligned with the grid.
Please refer attached images for more information.

So, is there any way to fix the distance between the two dates, so that they can come on a single position everytime?

Please reply as soon as possible.

Thanks.

Cannot focus any control under the BusyIndicator

Similar to:
http://www.telerik.com/community/forums/wpf/busy-indicator/busyindicator-over-listbox-has-style-issue.aspx

Steps:
1. Set IsBusy to true.
2. Set IsBusy to false.
3. Set focus to something (anything!) under the BusyIndicator.
Focus is never set. I've tried the control.Focus() method as well as FocusManager options.

Without setting IsBusy to true focus can be set as expected.

Has anyone else seen this?

What happened with v.2011.3.1116.40? DnD stopped working for me

I upgraded to the new version to try and get some of the bugfixes, but my DnD has stopped working. Trying to start a drag operation switches the cue to a no-drag icon and nothing gets dragged.

Are there changes in DnD that I missed in the release notes?

And, to be quite frank, I don't have the time to re-write my DnD code to cope with whatever it is you've done, so I also need to know how to downgrade my installation. Your "Upgrade Wizard" only knows how to upgrade, apparently. I need to get back to the previous version. What's the fastest and most accurate way to do this, please?

Filter for combobox column does not get displayed.

Hi,

I have the following xaml code , but I do not get any column filter shown, not even the default one(when removing the filter control) , is it because I am binding to an object and not a foreign key (ID) as the example you have in a blog post. http://blogs.telerik.com/pavelpavlov/posts/10-01-20/filtering-gridviewcomboboxcolumn-in-radgridview-for-wpf.aspx. Is it possible to filter when binding to an object ?.

<telerik:GridViewComboBoxColumn UniqueName="cmbActionBy" ShowFieldFilters="True" IsFilterable="True" IsComboBoxEditable="True" Header="Action by" DataMemberBinding="{Binding Path=tblContact}" telerik:TextSearch.TextPath="ShortName" DisplayMemberPath="ShortName" Width="80" SortMemberPath="tblContact.ShortName" EditorStyle="{Binding Source={StaticResource MyStyle}}">

<telerik:GridViewComboBoxColumn.FilteringControl>

<filter:ComboColumnFilteringControl IsActive="True" IsEnabled="true"></filter:ComboColumnFilteringControl>

</telerik:GridViewComboBoxColumn.FilteringControl>

</telerik:GridViewComboBoxColumn>

RadMaskedDateTimeInput: Possible to enter 0000-00-00 for "open end" ?

We're using the date value 9999-12-31 as a kind of "open end" or "umlimited" flag in RadMaskedDateTimeInput.
Is it possible to set up the control so that the entry 0000-00-00 is possible ?

(Our customers know this value from an older product and it's much easier to enter. The RadMaskedDateTimeInput may convert this value internally to 9999-12-31)

Best regards
Oliver

RowDetail record erased while sorting or filtering master grid.

Hi,
I have a gridview having a grid in its rowdetail, when row detail visibility changes i fetch data from database to load the row detail grid.
But the problem here is that when i sort or filter on the main grid, the data is removed from the already opened row detail grid.

Same thing happens when we have some controls in our rowdetails, and the values of expanded row details sets to blank when filtered or sorted.

Using "RowDetailsVisibilityChangedevent" to populate the rowdetails, due to some constraints not using "LoadingRowDetails".

Please let me know is there anything i can do so that those row detail grid data does not get removed when I do sorting or filtering on main grid.

Please reply its urgent.
Thanks
