Hi Vuyiswa,

Thank you for contacting us.

We already have this feature in our development plans, but for now I cannot give you a certain timeframe when it is going to be ready. Meanwhile, I can suggest you to refer to this forum discussion where you can find a sample project illustrating how this can be achieved.

Hope this information helps. Please let us know if you have further questions.

Kind regards,

Good Day

i looked at the example, i am not sure what is wrong with it. but i can visuall see the example control declared on the xaml. but i have created something interesting here. my xaml looks like this

<telerik:RadSplitButton HorizontalAlignment="Left" IsChecked="False" IsOpen="False" Margin="60,79,0,0" Name="radSplitButton1" Width="204" Height="27" VerticalAlignment="Top">

<telerik:RadSplitButton.DropDownContent>

<ListBox x:Name="lstAllergies" SelectionChanged="lstAllergies_SelectionChanged">

<ListBox.ItemsPanel>

<ItemsPanelTemplate>

<telerik:RadWrapPanel x:Name="Panelcheckbox" Width="180" Orientation="Horizontal" />

</ItemsPanelTemplate>

</ListBox.ItemsPanel>

</ListBox>

</telerik:RadSplitButton.DropDownContent>

</telerik:RadSplitButton>

and i am creating the items at runtime, but in my real app i am going to get the items from the database , so iw ill be binding this to an object and currently i am binding it like this

//Add the Checkboxes

for(int i=0 ; i < 8 ; i++)

{

CheckBox chkbox = new CheckBox();

chkbox.Name = "Allergy_" + i;

chkbox.Content = "Allergy_" + i;

lstAllergies.Items.Add(chkbox);

}

NOw i want to get the value path of the selected checkbox that being created onfly.

Thanks

Hello Vuyiswa,

I am not sure whether i understand your issue correctly. However, since you define CheckBoxes on top of the ListBoxItems (by populating the ListBox.Items collection with CheckBoxes), when you select a CheckBox the ListBox.SelectionChanged event won't befired since the underlying ListBoxItem cannot detect the LeftMouseButton event which indicates the selection. This is caused by the fact that the CheckBox handles this event instead.

Therefore you can define the ListBoxItems like so:

<telerik:RadSplitButton HorizontalAlignment="Left" IsChecked="False" IsOpen="False" Margin="60,79,0,0" Name="radSplitButton1" Width="204" Height="27" VerticalAlignment="Top" DropDownContent={Binding Allergies}>

<telerik:RadSplitButton.DropDownContentTemplate>

<DataTemplate>

<ListBox ItemsSource={Binding} SelectionChanged="SelectionChanged">

<ListBox.ItemTemplate>

<DataTemplate>

<StackPanel Orientation="Horizontal">

<CheckBox/>

<TextBlock Text={Binding Name}/>

</StackPanel>

</DataTemplate>

</ListBox.ItemTemplate>

</ListBox>

</DataTemplate>

</telerik:RadSplitButton.DropDownContentTemplate>

Give this a try and let us know if it works for you.
