How would I go about enabling the tool tip for a slot in the RadScheduleView. I already have a tool tip defined for the appointment, but I need to provide the user with additional information about each slot when they are trying to decide where to make their appointment.

Thank you in advance,

Stephen

Update filter when object content is modified

Hi,

I have a rad grid view in my application and I like the power of the column filtering.

My xaml looks like this:

<telerik:RadGridView AutoGenerateColumns="False" ItemsSource="{Binding Entries}" IsReadOnly="True" CanUserReorderColumns="False" CanUserDeleteRows="False" CanUserInsertRows="False" RowDetailsVisibilityMode="Visible" SelectionMode="Extended">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" Header="Name" IsReadOnly="True"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Connections}" Header="Connections" IsReadOnly="True"/>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

The gridview binds its itemssource to an observable collection.

When someone is filtering on the connections column and one of the items connection property changes, the filtered content is not updated. The updated value does appear in the column however (thanks to INotifyPropertyChanged). I noticed that when the collection changes the filter does work. Is there a way to trigger a filter update as well when a property like connections is updated?

Kind regards

[Solved] Use SecureString as PropertyType

Hi,

I must use a SecureString as a property type. Is it possible to edit the value in the PropertyGrid? How can I achieve this?

I already tried to get the value in the EditEnded event and tried to convert it on my own, but I do not get the value, it is null.

Thanks for your replies.

borders around clustered/stacked bars

I was wondering how to style dynamically-created clustered/stacked bar charts (created using ChartSeriesProvider), so that there is a border around each bar (i.e., be able to set BorderBrush and BorderThickness properties). Here is a code snipped of the *.xaml without borders.

<telerik:RadCartesianChart.SeriesProvider>

<telerik:ChartSeriesProvider Source="{Binding Data}">

<telerik:ChartSeriesProvider.SeriesDescriptors>

<telerik:CategoricalSeriesDescriptor ItemsSourcePath="Data" ValuePath="Sales" CategoryPath="Article">

<telerik:CategoricalSeriesDescriptor.Style>

<Style TargetType="telerik:BarSeries">

<Setter Property="CombineMode" Value="Stack" />

<Setter Property="local:ChartUtilities.SeriesStackGroupKey" Value="{Binding StackGroup}" />

<Setter Property="LegendSettings">

<Setter.Value>

<telerik:SeriesLegendSettings Title="{Binding NameInLegend}"/>

</Setter.Value>

</Setter>

</Style>

</telerik:CategoricalSeriesDescriptor.Style>

</telerik:CategoricalSeriesDescriptor>

</telerik:ChartSeriesProvider.SeriesDescriptors>

</telerik:ChartSeriesProvider>

Thanks!

Adjust row height by cursor

Hi,

I insert a table to a RichTextBox and formatting it with both built-in UI and programmatically as http://docs.telerik.com/devtools/wpf/controls/radrichtextbox/document-elements/features-tables.html#formatting-a-table-via-the-built-in-ui . However when I'm adjusting the height of table row, by programmatically it can be shorter than the default size when font size is 8 and by cursor the min height is the default height when the table is created. Is there anyway to make the mouse drag the row height smaller then that?

Thanks,

Yiping

Vertival Orientation GridViewImageColumn Cells

I'm using a GridViewImageColumn to display images that are smaller than the cell.

How do I change Horizontal Orientation or Vertical Orientation in XAML to let the image appear e.g. on top or on bottom of the cell?

RadGridView expands wrong Group

I have a problem with the Telerik Grouping. I can reproduce the error like this (Q3 2015):

Load a grid which contains about 8 which allows multi selection (amount does not matter)
Select one item (let's assume the first)
Group over a column, so that 4 collapsed groups appear
If i try to open a group, this will open and also the group, which contains the selected item

This behaviour is not as the user expect, because only the selected group should expand, not the one containing the selected item.

Maybe some one has a solution,

Thank you!
