I'm getting the following error whenever I click on an appointment on the schedule view. I can drag/drop appointments onto the schedule view but actually clicking on an appointment will give me the following error. Also note that this isn't just when I'm debugging my own WPF app in Visual Studio, this happens when I try to click on an appointment in the WPF Controls Example application aswell. Looks like it's trying to find a file on the C:\ drive that I can confirm is not there.

Generic types cannot be marshaled to COM interface pointers.

Locating source for 'c:\Builds\WPF_Scrum\Release_WPF\Sources\Development\Controls\ScheduleView\ScheduleView\Controls\AppointmentItem.cs'. Checksum: MD5 {87 50 ae 34 9e 6c a1 bb c7 7a 37 31 e6 5c 9e c8}
The file 'c:\Builds\WPF_Scrum\Release_WPF\Sources\Development\Controls\ScheduleView\ScheduleView\Controls\AppointmentItem.cs' does not exist.
Looking in script documents for 'c:\Builds\WPF_Scrum\Release_WPF\Sources\Development\Controls\ScheduleView\ScheduleView\Controls\AppointmentItem.cs'...

How to set red border programmatically

Hi Folks,
When I use entryfield validation by exception, controls paint a red border around itself on error.
How can I set this border from outside ?
(I.e. an outer "check function" gets called from somewhere and wants to set the red "error state" on an entryfield)
Is there something like radTextBox1.SetErrorState ???

Best regards
Torsten

[Solved] Binding controls w/i RadRibbonDropDownButton.DropDownContent

Hi.

I'm having a problem with the following code:

<telerik:RadRibbonDropDownButton.DropDownContent>

<StackPanel >

<StackPanel Orientation="Horizontal" x:Name="LayoutRoot">

<ListBox Name="ListBox" ItemsSource="{Binding Path=Columns, ElementName=TableGrid}">

<ListBox.ItemTemplate>

<DataTemplate>

<CheckBox Content="{Binding Header}"

IsChecked="{Binding IsVisible, Mode=TwoWay}" />

</DataTemplate>

</ListBox.ItemTemplate>

</ListBox>

<telerik:RadGridView Name="TableGrid" ItemsSource="{Binding Units}" ShowGroupPanel="False" />

</StackPanel>

</telerik:RadRibbonDropDownButton.DropDownContent>

This is the "Showing and hiding radgrid columns outside the radgrid" example from the Telerik website, in a dropdowncontent. When I run this and set the datacontext, "TableGrid" shows data properly but "ListBox" does not show the column headers. If I take the "LayoutRoot" stackpanel up a level, out of the radribbonbutton and into the radribbongroup driectly, it works fine ("ListBox" contains the "TableGrid" headers.) Poking around I've read that that the dropdowncontext doesn't share the same visual tree as the parent, but I would think I could bind controls from within the dropdowncontext. Can you point me in the right direction to resolve this please?

Thanks,
MR

Logviewer(listbox) not updating synchronously

I have used MVVm pattern in my application having three views.I wanted display log messages(status,error etc) in 1st window( in listbox ).I have created singleton class(loghelper) with function AddLog(),which i am calling whever i wanna update log msg & to write to log file also.so whenver this method gets called ,it triggers event(in loghelper class) and the eventhandler in respective view model gets called and there it adds log messages to Source(ObservableCollection which is bound to list box).
Now the problem is eventhough log message is added to collection for each log msg ,message is not updating synchronously in list box.View looks like freezing for a minute and all messages updates at a time.
I am not using multithreading here.

It it possible to style the RadPanes in such a way that each header has it's own closing X instead of 'just' the one placed on the right hand side?

Thanks,

Validating if information is entered

I am using the RadMaskedTextInput to contain a last name, a first name, city and several other random strings. I am trying to have the validation just test whether there is data in the field. I found a help file for doing something similar on the MaskedTextBox, but nothing for the more generic TextInput. Any help would be greatly appreciated.

The Validation help http://www.telerik.com/help/wpf/radmaskedinput-features-validation.html contains an exception called ValidationException which I cannot find a reference to in my Visual Studios. This looked like the proper way to go, but without access to that Exception I am stuck.

lockups after binding

i have a radtreelistview in my application that i am binding an object model to. After binding, i continue to update my object list. I notice that after binding and displaying my data, the entire application will lock up, or sometimes just the tree will lock up, and these lockups dont always correspond to my updating the data model, but are rather sporadic In addition, i notice that my memory usage balloons to a very large size, and then eventually settles back down again, at which point the lockups tend to reduce or go away. Im not at the office right noa so i cant post a code sample, i wil tomorrow, but has anyone else experienced this? Can anyone point me in the right direction? I am replacing a devexpress tree control with the radtreelistview and this was not happening with that. It also doesnt seem to happen with the syncfusion tree Thanks

[Solved] How to add Filter, Group and Sort for Column with CellTemplate

If a column has a celltemplate defined, its Filter, Sort and Group capability are gone. I'm sure there's a template perhaps that I can define to bring them back but I'm hoping it's more straightforward than that. If you're wondering why I use CellTemplate, it's because I need a CheckBox that uses a Command.

How do I go about this predicament?
