Hi Thomas, 

 

Thanks for using Syncfusion product. 

 

We have checked your requirement to change the text "Select all" in a ComboBoxAdv and you can able to achieve your requirement by customizing the style of the control. Here you can able to initialize the text to Content of the ComboBoxItemAdv as like below code snippet, 

 

<syncfusion:ComboBoxAdv x:Name="comboBoxAdv" Style="{DynamicResource ComboBoxAdvStyle1}" AllowMultiSelect="True" AllowSelectAll="True" HorizontalAlignment="Left" Height="34" Width="311" Margin="118,66,0,0" SelectionChanged="ComboBoxAdv_SelectionChanged"> 

    <ListBoxItem Content="item1"/> 

    <ListBoxItem Content="item2"/> 

    <ListBoxItem Content="item3"/> 

</syncfusion:ComboBoxAdv> 

 

<Style x:Key="ComboBoxAdvStyle1" TargetType="{x:Type syncfusion:ComboBoxAdv}">            

            <Setter Property="Template"> 

                <Setter.Value> 

                    <ControlTemplate TargetType="{x:Type syncfusion:ComboBoxAdv}"> 

 

……. 

<syncfusion:ComboBoxItemAdv x:Name="PART_SelectAll" Background="{Binding Background, ElementName=DropDownBorder}" Content="SelectAll item" Margin="0.2,0,0,0.5" Grid.Row="0"> 

    <syncfusion:ComboBoxItemAdv.Visibility> 

        <TemplateBinding Property="AllowSelectAll"> 

            <TemplateBinding.Converter> 

                <BooleanToVisibilityConverter/> 

            </TemplateBinding.Converter> 

        </TemplateBinding> 

    </syncfusion:ComboBoxItemAdv.Visibility> 

</syncfusion:ComboBoxItemAdv> 

 

……….

Hi Jagadeesan,

Ok, it works.

But is there an easier way than overwriting the entire template?

Hi Thomas, 

 

Thanks for your update. 

 

We have checked your query and you can able to rename the SelectAll item, by using the below code snippet. Here you can get the SelectAllItem using reflection and change the content as like below code snippet, 

 

public MainWindow() 

{ 

    InitializeComponent(); 

    this.Loaded += OnLoaded; 

    this.comboBoxAdv.DropDownOpened += ComboBoxAdv_DropDownOpened; 

} 

 

private void ComboBoxAdv_DropDownOpened(object sender, EventArgs e) 

{ 

    FieldInfo infor = typeof(ComboBoxAdv).GetField("SelectAllItem", BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance); 

    var value = infor.GetValue(this.comboBoxAdv) as ComboBoxItemAdv; 

    value.Content = "Select All Item"; 

}
