Custom Row Template

Hello,

I am trying to create a row template which is only applied to certain items. It is not clear which template governs the row in a treelistview (is it a GridViewGroupRow or a GridViewRow). Additionally, I appear to be unable to modify a copy of either the RowStyle or the GroupRowStyle in Expression Blend. Are the XAML representations of the default styles listed somewhere?

Cheers,

Mike

[Solved] Want to programmatically control whether row details are displayed for a given row

I have a RadGridView control on a screen in my WPF application. It holds the results of a search the user can perform. There are two different types of objects that can be in this control; they both implement an interface that the window that holds the RadGridView is aware of.

One of these two types contains an array of a third type of object that I want to display in a Row Details data template, but only if the array isn't empty. The other type does not have any information in it that I want to display in any row details area.

So I need a way to set the Row Details Visibility property for each row in the RadGridView based on its underlying type. I've already added a boolean property called CanDisplayDetails. For the type that I don't want to display any details for, this always returns false. Of the other type, this returns true if the number of rows in an array property is greater than zero.

How do I hook this property up to each row's DisplayRowDetails property?

RadChart Not Refreshing Correctly?

I have a RadChart (2011-Q3) with a single X axis and 2 Y axis's. The right Y axis gets its MaxValue and Step from binding to properties in my associated view model. Every three minutes the underlying data in the VM refreshes itself. I'm noticing that when the underlying data refreshes itself, the data on the chart refreshes, but the right Y axis does not. It does not attempt to retrieve new values for the MaxValue and Step. I've determined this by setting breakpoints on my getter properties. The getter is called once, when the chart first loads, and is never called again, even when the chart data refreshes.

Is this a bug in the Chart control, or is there something I need to do to cause the entire chart to refresh (including the axix's) when the underlying data refreshes?

RadScheduleView appointment changes commit.

Hello,

I'm trying to replace the window that appears on AppointmentEditing event of the radscheduleview.

I'm updating an appointment, then I try to commit the changes with .Commit() method (which actually returns false -> there must be an error in this method, but I can't see it :P )

I'll give you a code snippet of what i'm trying to do:

private void AppointmentEditingHandler(object sender, AppointmentEditingEventArgs e)

{

try

{

...

var appointment = e.Appointment;

...

var radScheduleView = (RadScheduleView)e.Source;

appointment.BeginEdit();

appointment.Start = newStartDateTime;

appointment.End = newStopDateTime;

appointment.Subject = courseTypeToString;

appointment.EndEdit();

radScheduleView.Commit();

e.Handled = true;

e.Cancel = true;

e.RoutedEvent = null;

}

catch (exception ex)

{}

I've tried every single thing on your forum but I haven't manage to make it work.

Please help me with the above issue, it's VERY annoying.

Combobox row via DataTemplateSelector, how to detect when they should be disabled?

Hi all,

I've made the first row of my grid contain comboboxes using a DataTemplateSelector. This works like a charm.

My problem is associated with validation errors when they occur in a cell in a different row. When a cell fails to validate, the cells in the rest of the grid become readonly and non-focusable, or disabled in some fashion, so the focus cannot be changed to a different cell in the grid. However, the comboboxes remain enabled. I want to disable them but cannot find a property in the tree above them to bind to.

I am trying to use something like:

const string xaml =

"<DataTemplate>"

+

"<ComboBox Tag=\"{0}\" IsEnabled=\"{{Binding Path=IsEnabled, RelativeSource={{RelativeSource FindAncestor, AncestorType=telerik:GridViewCell}}}}\" />"

+ "</DataTemplate>";

string dataTemplateXaml = string.Format(xaml, fieldIndex);

In this example, I am looking to the IsEnabled property on the enclosing GridViewCell but it does not work. I've used Snoop to walk up the tree to the RadGridView to find a property to which I can bind to get the correct behavior. I cannot find a property that changes when there is a validation error in a cell in the grid.

Maybe I'm way off base on this approach. Suggestions would be greatly appreciated.

RadTreeViewItem highlight colour

Hello,

Please see the attached screenshots of my RadTreeViewItems. As you can see, when the tree has lost focus, the highlight colour of the SelectedItem becomes almost impossible to distinguish from an unselected item and this is causing usability issues with our users. I would like to know how to make the highlight colour not change when the tree has lost focus.

Thanks,

Ammaar.
