Hi Roshan,

If you need to customize the content, for example to set a localized string to a Label, you can define your own LoadOnDemandTemplate.

For example:

<telerikDataControls:RadListView.LoadingOnDemandItemTemplate>

<DataTemplate>

<Grid>

<Label Text="Bind this to your localized string" />

</Grid>

</DataTemplate>

</telerikDataControls:RadListView.LoadingOnDemandItemTemplate>

Hi Roshan,

Take a look at the RadListView Load On Demand Advanced section of the documentation for a complete description and more examples.

The two templates you can set are:

- LoadOnDemandTemplate (this is the 'load more" button)
- LoadingOnDemandTemplate (this is shown while the next set of items are being fetched)

You have 100% control over the appearance in that template, if you want it to look like the default appearance, you can design your custom template that way.

Here's an example using both templates with a mock static helper class for the translation properties

<telerikDataControls:RadListView x:Name="listView"

IsLoadOnDemandEnabled="True"

LoadOnDemand="ListView_LoadOnDemand"

LoadOnDemandMode="Manual">

<telerikDataControls:RadListView.LoadOnDemandItemTemplate>

<DataTemplate>

<Grid BackgroundColor="Yellow"

Padding="5">

<Label Text="{x:Static local:MyTranslationHelper.LoadMoreItemsText}"

TextColor="Black"

FontSize="24"

HorizontalOptions="Center" />

</Grid>

</DataTemplate>

</telerikDataControls:RadListView.LoadOnDemandItemTemplate>

<telerikDataControls:RadListView.LoadingOnDemandItemTemplate>

<DataTemplate>

<Grid BackgroundColor="Green"

Padding="5">

<Label Text="{x:Static local:MyTranslationHelper.LoadingMoreItemsText}"

TextColor="White"

FontSize="24"

HorizontalOptions="Center" />

</Grid>

</DataTemplate>

</telerikDataControls:RadListView.LoadingOnDemandItemTemplate>

</telerikDataControls:RadListView>
