Hi guys,

I have a WPF code as below :

VB

<UserControl x:Class="Sample"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:view="Sample.view"
             xmlns:viewModel="Sample.viewModel"
             Width="auto" VerticalAlignment="Top">

XML

<UserControl.Resources>
    <DataTemplate DataType="{x:Type viewModel:SelectionViewModel}">
        <view:Transaction />
    </DataTemplate>
    <DataTemplate DataType="{x:Type viewModel:ConfigurationViewModel}">
        <view:Configuration />
    </DataTemplate>
</UserControl.Resources>

</UserControl>

I would like to add Those DataTemplates into Resources Programatically in Code behind.

My query is how to create data template programatically and how to add it into resoruces in code behind?

Thanks :)

According to the SDK, the recommended way to programmatically create a template is to load XAML from a string or a memory stream using the XamlReader.Load() method. Believe me, that's the easiest way. It's very easy to build the necessary xaml string dynamically, and then load it.

To add the template to your Resources, you probably should create a ResourceDictionary with your template in it, use XamlReader.Load to load the xaml, and then merge the dictionary, like so.

C#

this.Resources.MergedDictionaries.Add(myResourceDictionary);
