Customize the TextBox
The appearance of the TextBox part of RadAutoSuggestBox can be customized via the TextBoxStyle property of the control.
The TextBoxStyle property expects a Style object with a TargetType set to RadWatermarkTextBox.
Example 1: Setting TextBoxStyle
<telerik:RadAutoSuggestBox Foreground="Red">
<telerik:RadAutoSuggestBox.TextBoxStyle>
<!-- The BasedOn property is required when using NoXaml dlls. Otherwise, remove the setting. -->
<Style TargetType="telerik:RadWatermarkTextBox" BasedOn="{StaticResource RadWatermarkTextBoxStyle}">
<Setter Property="Opacity" Value="0.5" />
<Setter Property="FontWeight" Value="Bold" />
</Style>
</telerik:RadAutoSuggestBox.TextBoxStyle>
</telerik:RadAutoSuggestBox>
