问题 I have a function in .xaml.cs which i wanted to call: .xaml.cs private void treeView_SelectedItemChanged(object sender, EventArgs e) { //treeView.ScrollToCenterOfView(sender as TreeViewItem); } like from this post: Make ListView.ScrollIntoView Scroll the Item into the Center of the ListView (C#) Answer 1 But i dont use the SelectedItem, my approach would be like: XAML: <Style.Triggers> <DataTrigger Binding="{Binding Path=IsActive}" Value="true"> // ###call this function </DataTrigger> </Style

问题 This question already has answers here : Static binding doesn't update when resource changes (2 answers) Closed 2 years ago . I am using DataTrigger to change the background color in WPF. I have a property in Globals Class which have a true and false value. I check a lot of code from Stackoverflow but I didn't get it working. Please check. <Grid Height="350" Width="525" Name="gridTesting"> <Grid.Style> <Style TargetType="{x:Type Grid}"> <Style.Triggers> <DataTrigger Binding="{Binding

问题 This is the code: <Grid> <Ellipse Fill="Turquoise" HorizontalAlignment="Left" Height="100" Stroke="Black" VerticalAlignment="Top" Width="100"> <Ellipse.Style> <Style TargetType="Ellipse"> <Style.Setters> <Setter Property="Ellipse.RenderTransform"> <Setter.Value> <TranslateTransform X="0" Y="50"/> </Setter.Value> </Setter> </Style.Setters> <Style.Triggers> <DataTrigger Binding="{Binding ElementName=rectRight, Path=IsMouseOver}" Value="True"> <DataTrigger.EnterActions> <BeginStoryboard>

问题 I have a ComboBox and a Button on my main view, and I want to apply a style to the button such that when the combobox index is set to 1, the button becomes visible (initially it's hidden). This is my XAML code: <Grid> <StackPanel Orientation="Vertical" Margin="10"> <ComboBox Name="comboBox"/> <Button Name="myBtn" Content="Hello" Visibility="Hidden"> <Button.Style> <Style TargetType="{x:Type Button}"> <Style.Triggers> <DataTrigger Binding="{Binding ElementName=comboBox, Path=SelectedIndex}"

问题 I would like to use a DataTrigger to modify the opacity of my button. <Button x:Name="StartTreatment" Grid.Column="3" Width="160" Height="30" Content="{x:Static resources:UserMessages.TrcsConsoleViewModel_LoadWfSequence_StartProcedure}" IsEnabled="{Binding CanStartProcedure}" Visibility="{Binding CanStartPatientTreatment, Converter={StaticResource BooleanToVisibility}}" > <Button.Style> <Style> <Style.Triggers> <DataTrigger Binding="{Binding CanStartProcedure}" Value="False"> <Setter Property

问题 iv'e got several itemscontrols which i need to attach an event handler for their PreviewMouseLeftButtonDown event only when a certain condition is met . iv'e designed a style for my controls with a datatrigger ,i checked out it's bindings and tried it out with a regular property setter for the BorderThickness Property just to see that the datatrigger works .

问题 I would like to have a button that blinks/animate when triggered by DataTrigger. I want to animate the button's background.

问题 So I have a combobox I'd like to reuse for multiple sets of data rather than having 3 separate comboboxes. Maybe this is bad and someone can tell me so. I'm open to all ideas and suggestions. I'm just trying to clean up some code and thought one combobox rather than 3 was cleaner. Anyway the ItemsSource and SelectedItem all should change when another ComboBox's value is changed which Raises the Property Changed value for the ComboBox that isn't working. The worst part is when CurSetpoint
