Adding a Command

By default, the toolbar of RadChat will not be visible. When a ToolBarCommand is added to the ToolBarCommands collection, the ToggleButton for opening the toolbar will appear next to the Send Button. The ToolBarCommand element exposes the following two properties:

• Text: The text Content that will be set to the generated Button.
• Command: The ICommand that is to be executed when clicking the Button.

Adding a ToolBarCommand to the ToolBarCommands collection

C#

this.chat.ToolBarCommands.Add(new ToolBarCommand() { Text = "Click", Command = new DelegateCommand(MyCommandLogic) });

ToolBarCommandTemplateSelector

RadChat supports defining custom DataTemplate for the elements generated in its toolbar. This is done via its ToolBarCommandTemplateSelector property. Its conditional logic can be implemented based on the given ToolBarCommand.

Defining a custom DataTemplateSelector

C#

public class ToolBarCommandTemplateSelector : DataTemplateSelector
{
	protected override DataTemplate SelectTemplateCore(object item, DependencyObject container)
	{
		var toolBarCommand = item as ToolBarCommand;

		if (toolBarCommand.Text == "Block")
		{
			return ClickTemplate;
		}
		else
		{
			return this.DefaultTemplate;

		}
	}

	public DataTemplate ClickTemplate { get; set; }
	public DataTemplate DefaultTemplate { get; set; }
}

Define the custom DataTemplateSelector in XAML.

Adding the ToolBarCommandTemplateSelector

XAML

<Grid.Resources>
	<my:ToolBarCommandTemplateSelector x:Key="ToolBarCommandTemplateSelector">
		<my:ToolBarCommandTemplateSelector.ClickTemplate>
			<DataTemplate>
				<Button Content="{Binding Text}" Foreground="Red"/>
			</DataTemplate>
		</my:ToolBarCommandTemplateSelector.ClickTemplate>
		<my:ToolBarCommandTemplateSelector.DefaultTemplate>
			<DataTemplate>
				<Button Content="{Binding Text}"/>
			</DataTemplate>
		</my:ToolBarCommandTemplateSelector.DefaultTemplate>
	</my:ToolBarCommandTemplateSelector>
</Grid.Resources>

Finally, the custom template selector can be set to the ToolBarCommandTemplateSelector property of RadChat.

Applying the ToolBarCommandTemplateSelector

XAML

<telerik:RadChat x:Name="chat" ToolBarCommandTemplate="{x:Null}" ToolBarCommandTemplateSelector="{StaticResource ToolBarCommandTemplateSelector}"/>
