1. I have implemented a class called CustomGridViewToggleRowDetailsColumn which descends from GridViewBoundColumnBase.  This class has properties that allow me to hide the GridViewToggleButton for a row if that row does not have any row details.  It also has a Click event that is raised whenever the user clicks on the GridViewToggleButton.
2. In my class that populates the rows of the RadGridView, I have implemented INotifyPropertyChanged.
3. In the window that has the RadGridView, I retrieve my data from the database but leave the Alarms property (which is bound to the DataGrid's ItemsSource property in the DataTemplate) set to null initially.  A bool property called HasAlarms is set to true if the row has Alarms associated with it.
4. In the window that has the RadGridView, I have a Click event handler for the custom Click event I mentioned in #1.  This checks to see if the Alarms property for the row that was clicked is null.  If it is, it goes to the database and retrieves the Alarms.  Note that this event can't happen unless HasAlarms is set to true for that row.

This is all working, but the DataGrid remains empty after the RowDetails are displayed.  What am I missing to make this work?

I sent a support ticket to the telerik admins asking if there were any API methods to determine if the caret is at the start and end of a line.
They responded with a solution so I thought I should share it with everyone else.

Is Caret at Line Start

Is Caret at Line End

I hope this helps you as it did myself.

Thanks,

Hi,

I'm trying to use the RadMaskedNumericInput as follows;

<telerik:RadMaskedNumericInput
                Grid.Row="6"
                Grid.Column="1"
                Value="{Binding Mileage}"
                EmptyContent="kilometer"
                FormatString="D"
                Mask="d"
                IsClearButtonVisible="False"
                VerticalAlignment="Center"
                VerticalContentAlignment="Center"
                />
